Florida Family Law Rules of Procedure Form 12.917(a), titled the Income Withholding for Support (IWO), is the standardized order a Florida court or child support agency sends to an employer (the “income payor”) that legally requires the employer to pull child support, alimony, or related arrears directly from a parent’s paycheck. The form is the Florida adoption of the federal OMB-approved IWO issued under 42 U.S.C. § 666(b), and it is the only form a court, agency, attorney, or private party may use to start income withholding in Florida.
Getting it wrong has real consequences: an Office of Child Support Enforcement audit found that roughly 75% of all child support collected nationwide comes through income withholding, yet OCSE rejection data shows nearly 1 in 5 IWOs sent to employers gets bounced back the first time because of formatting errors in the Remittance Identifier, FIPS code, or CCPA boxes. A bounced IWO means no money moves until the order is corrected and resent.

What Form 12.917 Is and Who Must File It
Florida Form 12.917(a) is the Income Withholding for Support order, a single multi-page form that tells an employer to withhold a specific amount from an employee’s earnings and send it to the Florida State Disbursement Unit (SDU) for the benefit of a child or a former spouse. The form is required by Florida Statute § 61.1301, which automates withholding for every Florida support order entered or modified after October 1, 1996. The form is also required by Florida Family Law Rule of Procedure 12.491 when a child support hearing officer recommends withholding.
Three categories of senders use this form: – A state child support agency (the Florida Department of Revenue, Child Support Program), which sends the IWO directly to employers without a separate court order. – A court, when a judge or magistrate enters a child support, alimony, or modification order. – A private party or attorney, who prepares the IWO for the judge’s signature and serves it on the employer after the support order is entered.
The form must be used for both child support and alimony when the alimony is paid through the SDU, but private alimony orders that bypass the SDU use a different mechanism. If you are unsure whether your alimony order qualifies, check the language of your final judgment for a “central depository” clause as required by Fla. Stat. § 61.181.
The receiver of the form is the employer or other income payor, which can be a traditional W-2 employer, a payroll service, an unemployment compensation office, a workers’ compensation carrier, a pension administrator, or a 1099 payor where Florida law allows withholding. Each receiver type has slightly different rules for when withholding starts and how lump sums are treated, and those rules are anchored to 45 C.F.R. § 303.100.
Before You Start: Documents and Information You Need
Pull these eight items together before you open the PDF, because the IWO will reject if any one of them is wrong, missing, or formatted incorrectly. The form is unforgiving of typos in identifying numbers, and a single wrong digit in a Social Security number will cause the employer to refuse the order under federal IWO instructions.
- The certified copy of the underlying support order. Without the order, you have no legal basis for withholding, and the employer may demand to see the order before honoring the IWO. Keep the case number, judge’s name, and date of entry handy.
- The obligor’s full legal name, current address, date of birth, and Social Security number. A mismatched SSN is the single most common reason for rejection. Pull the SSN from the financial affidavit or final judgment, not from memory.
- The custodial party’s full legal name and mailing address. This goes in the “Employee/Obligor’s Name” and “Custodial Party” fields and must match the name on the underlying order, not a remarried name unless the order was modified.
- Each child’s full legal name and date of birth. The form has space for up to six children, and listing more requires an attachment.
- The employer’s exact legal name, FEIN (if known), and mailing address. Use the FEIN-registered name from the SUNBIZ database, not a “doing business as” name.
- The Florida FIPS code for the issuing county. Florida’s FIPS codes are listed on the Census Bureau county code page, and they are five digits beginning with 12.
- The remittance identifier, which in Florida is the Depository Number assigned by the State Disbursement Unit, found on the SDU payment coupon.
- The current support amount, arrears amount, medical support amount, and any other obligation broken out by frequency (monthly, weekly, bi-weekly, semimonthly).
If any one of these items is missing, stop and gather it first. Filing a guess is worse than filing late, because employers are required by Fla. Stat. § 61.1301(2)(e) to reject a defective IWO and the obligor may rack up arrears while you fix it.
Where to Get the Form and How to Access It
The official, fillable PDF of Florida Form 12.917(a) lives on the Florida Courts family law forms library and is the only version a Florida judge will sign. Never use a third-party copy, a county-customized version, or a federal-only OMB-0970-0154 PDF, because the Florida-specific instructions on page 1 are mandatory.
You may also access the form through: – The Florida Department of Revenue Child Support Program forms page, which posts the same PDF for state-initiated IWOs. – The Florida Bar family law section, which mirrors the form for member attorneys. – Your county clerk’s self-help center, where most clerks keep printed packets and computer kiosks.
The form is fillable on a desktop with Adobe Acrobat Reader, but the federal IWO checkboxes do not always render in browser-based PDF previews, so always download the file before completing it. Save your working copy with a clear file name such as Smith-IWO-2026-05-27.pdf so you can find it again if the clerk asks for a corrected version.
If you are a Florida Department of Revenue caseworker, the IWO is auto-generated from the state CAMS system and you should not download a blank copy. Private filers and attorneys, however, must complete the PDF manually or through case management software that uses the federal IWO XML schema.
Step-by-Step: How to Fill Out Form 12.917 Line by Line
The form is divided into a heading block, a “to” block (employer), a “from” block (sender), an order details section, a remittance section, an employer compliance section, an employee notification section, and a signature block. Each section below is broken into its individual fields with the six-element walkthrough required for accuracy.
Heading: Type of IWO Checkboxes
The first set of boxes at the top tells the employer what kind of IWO this is. The choices are Original IWO, Amended IWO, One-Time Order/Notice for Lump Sum Payment, and Termination of IWO.
In plain English, you are telling the employer whether this is a brand-new withholding instruction, a change to one already in place, a one-time grab from a bonus or settlement, or a stop notice. Check exactly one box. Use Amended IWO whenever you are changing dollar amounts on an existing withholding, even by a single penny.
For example, Maria Lopez is enforcing a new child support judgment entered last week, so she checks Original IWO. If a court later raised her child support from $400 to $475, she would check Amended IWO on a fresh form.
A common edge case: filers often confuse Amended with One-Time. One-Time applies only to lump sum payments such as severance, settlements, or bonuses, and is governed by 45 C.F.R. § 303.100(a)(11).
The most common mistake here is checking both Original and Amended, which causes the employer to return the order as unprocessable under the federal instructions and stalls collection by 14 to 30 days. A frequent misconception is that an Amended IWO cancels the original; it does not — it replaces it, and the employer overwrites the prior dollar amounts on the same payroll record.
Heading: Date of IWO
This field captures the date you are sending the IWO, not the date the underlying order was entered.
Enter the date in MM/DD/YYYY format with leading zeros and forward slashes, exactly as the federal instructions require. The employer uses this date to calculate the 7-business-day implementation deadline imposed by Fla. Stat. § 61.1301(2)(e).
For example, Maria Lopez writes 05/27/2026 because she is mailing the IWO that day.
The edge case is post-dating, which filers sometimes try to do when they want withholding to begin on a paycheck cycle. Do not post-date; the federal IWO is effective the day the employer receives it, period.
The most common mistake is using a two-digit year, which causes some payroll systems to read 05/27/26 as 1926 and reject the order. The misconception is that the date controls the first paycheck withholding; it does not — the first paycheck rule is “the first pay period that occurs 14 days after the date the IWO was received,” per federal regulation.
Heading: Child Support Enforcement (CSE) Agency, Court, Attorney, or Private Individual/Entity
This radio-style line identifies who is sending the IWO. The four options are State/Tribal CSE Agency, Court, Attorney, and Private Individual/Entity.
Pick exactly one. Florida Department of Revenue uses State/Tribal CSE Agency; clerks of court use Court; family law attorneys use Attorney; and pro se parents use Private Individual/Entity. Each label triggers different rights for the employer to demand a copy of the underlying order.
For example, Carlos Rivera, a pro se father enforcing his alimony order, marks Private Individual/Entity, while attorney Janet Kim representing a custodial mother marks Attorney.
The edge case is a sender who is both an attorney and the parent. The federal instructions tell you to use the highest authority you legally hold, so an attorney-parent uses Attorney.
The common mistake is a private filer marking Court, which is only for the clerk or judge. That misclassification gives the employer the right to demand a copy of the order under federal rules, and most employers will hold the IWO until they receive it. The misconception is that marking Court gives the IWO more weight; it does not, and falsely doing so can be sanctionable.
Heading: Document Tracking Identifier
This is a free-text field where the sender places an internal tracking number. Florida senders typically use the case number from the underlying support order.
Enter the full case number with all dashes and spaces exactly as it appears on the final judgment, in the format used by the Florida State Courts case number standard.
For example, Maria Lopez enters 2025-DR-014592-FC-04 because that is the case number on her Final Judgment of Paternity.
The edge case is multi-county or transferred cases; always use the case number of the currently issuing court, even if the order originated elsewhere.
The most common mistake is leaving this field blank. A blank tracking ID makes it impossible for the employer to match returned funds to the right case, and they will reject the IWO. The misconception is that this is the “remittance identifier” — it is not; the remittance identifier is a separate and far more important field discussed below.
“Remittance Identifier” (a.k.a. Case Identifier or Order Identifier)
The Remittance Identifier is the single most important field on the entire form because it is the data the SDU uses to credit the right account. In Florida, this is the State Case Number (also called the IV-D number) or the SDU Depository Number for the case.
Enter the number in the exact format the SDU prints on its payment coupons, which is typically a 10-digit number with no dashes. You can find it on the MyFloridaCounty SDU portal by logging in as the custodial parent.
For example, Maria Lopez’s SDU depository number is 6500214893, so she enters 6500214893.
A nuance: if the case has both a federal IV-D number and a county depository number, the federal IV-D number wins. If you have neither, call the SDU at 1-877-769-0251 before filing.
The most common mistake is entering the court case number in this box. That single error is the leading cause of rejected IWOs nationwide and means the money will go to the wrong account or sit in suspense for 30 to 60 days. The misconception is that the SDU can “look it up” if the number is wrong; the SDU cannot — automated payments require an exact match.
Employee/Obligor’s Name (Last, First, Middle)
This is the legal name of the parent paying support, also called the obligor.
Enter the name in LAST, FIRST MIDDLE order in ALL CAPS, exactly as it appears on the obligor’s Social Security card. Do not use nicknames, suffixes in the first-name slot, or married-name aliases.
For example, the obligor’s full legal name is RIVERA, CARLOS ANTONIO, so the filer enters that exact string.
The nuance: hyphenated last names should keep the hyphen, and a single-letter middle initial should appear without a period.
The most common mistake is reversing first and last name, which causes payroll systems that match by last-name-first to fail to identify the employee, especially when the obligor’s first name is also a common surname. The misconception is that the field accepts a “preferred name” — it does not; payroll systems match against the SSA database, and a mismatch triggers a hold.
Employee/Obligor’s Social Security Number
A nine-digit identifier that ties the IWO to a specific worker.
Enter the SSN in XXX-XX-XXXX format with dashes. Pull it from the underlying order or financial affidavit, never from memory.
For example, Carlos Rivera’s SSN on file is 123-45-6789, so the filer enters 123-45-6789.
The nuance: ITINs (Individual Taxpayer Identification Numbers) are accepted only when the obligor has no SSN; mark the field clearly with ITIN in parentheses.
The most common mistake is transposing two digits, which causes the employer’s payroll system to fail to find the employee and return the IWO as “no match.” The misconception is that the last four digits are enough — they are not; full SSN is required by federal IWO standards.
Employee/Obligor’s Date of Birth
A secondary identifier used to confirm employee identity when SSN matching is ambiguous.
Enter as MM/DD/YYYY with leading zeros. Use the date on the obligor’s birth certificate or driver’s license.
For example, Carlos Rivera was born March 14, 1985, so the filer enters 03/14/1985.
The nuance: if the date of birth is unknown, leave the field blank rather than guessing — a wrong DOB combined with a right SSN can still trigger an employer rejection.
The most common mistake is using a two-digit year. The misconception is that DOB is optional; while the federal form will accept a blank, some Florida employers require it under their internal compliance rules and will hold the order until you supply it.
Custodial Party/Obligee’s Name
The legal name of the person to whom support is owed, typically the custodial parent.
Enter in LAST, FIRST MIDDLE order, ALL CAPS, matching the underlying order.
For example, LOPEZ, MARIA ELENA.
The nuance: in Florida Title IV-D cases, the obligee may be the State of Florida, Department of Revenue, not the parent, when the custodial parent receives or received TANF. In that case enter FLORIDA DEPARTMENT OF REVENUE in this slot.
The most common mistake is using a remarried name not reflected on the order. The misconception is that the obligee field controls who receives the money; it does not — the SDU does, and the SDU pays whoever is listed on its records.
Child(ren)’s Name(s) and Birth Date(s)
Up to six children may be listed in the table on page 1.
For each child, enter LAST, FIRST MIDDLE in one column and MM/DD/YYYY in the other. List children in order of birth.
For example, Maria Lopez lists RIVERA, SOFIA ISABELLA, 06/12/2018 and RIVERA, MATEO CARLOS, 09/03/2020.
The nuance: stepchildren or non-subject children are never listed here, even if the obligor supports them informally.
The most common mistake is omitting a child whose support obligation has terminated (aged out). The misconception is that listing more children increases the withholding; it does not — the dollar amount controls.
Order Information: Amounts to Withhold
This is the heart of the form, listing each periodic obligation in dollars.
The form has separate lines for current child support, past-due child support, current cash medical support, past-due cash medical support, current spousal support, past-due spousal support, and other. Each line has its own frequency dropdown (per weekly, biweekly, semimonthly, monthly).
For example, Maria Lopez’s judgment orders $425.00 current child support per month and $50.00 per month toward $1,800 in arrears. She enters $425.00 and Monthly on the current line and $50.00 and Monthly on the past-due line.
The nuance: the form requires you to normalize the frequency to match the employer’s payroll cycle elsewhere on the form, but in this section you enter the frequency as written in the order.
The most common mistake is using inconsistent frequencies — entering monthly amounts in a weekly box. That causes the employer to under- or over-withhold by a factor of 4.33 and creates an arrears nightmare.
The misconception is that the total dollar amount is what governs; it is not — the frequency-amount pair governs, and a $100 entry can mean very different things at different frequencies.
CCPA Withholding Limit (Box 9)
The Consumer Credit Protection Act caps how much of a worker’s “disposable earnings” can be withheld for support, found at 15 U.S.C. § 1673(b).
Check the box that matches the obligor’s situation: 50% (supports a second family, not in arrears 12+ weeks), 55% (supports a second family, arrears 12+ weeks), 60% (no second family, not in arrears 12+ weeks), or 65% (no second family, arrears 12+ weeks).
For example, Carlos Rivera has remarried with a new child but is current, so the filer checks 50%.
The nuance: “second family” means a current spouse or child, not a girlfriend or stepchild without legal duty.
The most common mistake is leaving Box 9 blank. A blank Box 9 forces the employer to default to the lowest possible cap or reject the order. The misconception is that the court order can override CCPA — it cannot; CCPA is a federal ceiling.
Remit Payment To: State Disbursement Unit
This block tells the employer where to send the money. In Florida, the answer is always the Florida State Disbursement Unit.
Enter: – State Disbursement Unit: FLORIDA STATE DISBURSEMENT UNIT – SDU/Tribal Order Payee: leave blank for SDU payments – Address: P.O. Box 8500, Tallahassee, FL 32314-8500
For example, every Florida IWO uses the address above; the SDU does not have alternate addresses, and you can confirm at the Florida Department of Revenue SDU page.
The nuance: tribal cases or non-IV-D alimony with a private payee are the only exceptions, and they require additional language under Fla. Stat. § 61.181.
The most common mistake is sending payment to the custodial parent’s home address, which violates Florida’s central depository requirement and exposes the obligor to a duplicate-payment claim. The misconception is that the parties can “agree” to bypass the SDU; with a Title IV-D case, they cannot.
Remittance Method: EFT/EDI
This block tells the employer how to send funds electronically.
Enter the SDU’s routing number (063100277 for Florida) and account information as published on the Florida SDU employer page. Most employers send via EFT under the CCD+ ACH format.
For example, payroll giant ADP uses EFT to remit to the Florida SDU using the published routing data.
The nuance: small employers without EFT capability may send paper checks to the SDU P.O. Box.
The most common mistake is entering an out-of-state SDU routing number copied from a federal sample IWO. The misconception is that EFT is optional; while it is technically optional for the employer, paper remittance delays posting by 5 to 10 business days.
Signature of Judge/Issuing Official
The bottom of the form requires the signature of the official issuing the IWO.
For court orders, this is the judge or magistrate. For state agency IWOs, it is the Department of Revenue’s authorized signatory under a digital signature system. For attorney-issued IWOs, it is the attorney’s signature, and for pro se IWOs, it is the obligee’s signature, but only after the underlying support order is entered.
For example, Janet Kim, Esq. signs the IWO on behalf of her client and prints her Florida Bar number below the signature.
The nuance: a judge’s signature is not required on every IWO, because Fla. Stat. § 61.1301 authorizes immediate withholding by operation of law in IV-D cases.
The most common mistake is forging or photocopying a signature; the IWO must bear an original or properly executed digital signature. The misconception is that an unsigned IWO is “still valid because the order is” — it is not, and the employer will reject it on sight.

How to File the Completed Form
Florida 12.917 has four delivery channels, and you may use more than one in a single case (e.g., e-file with the court and serve the employer by mail).
Channel 1: Florida Courts E-Filing Portal. Attorneys and most pro se litigants e-file the IWO through the E-Filing Portal under document type Income Withholding Order. There is no separate fee for filing the IWO when it accompanies an existing case; if filed as a stand-alone enforcement, the clerk’s enforcement fee under Fla. Stat. § 28.241 may apply, currently $50. Processing takes 1–3 business days, and your proof of filing is the portal-generated Notice of Electronic Filing.
Channel 2: In Person at the Clerk of Court. Bring two paper copies plus the original to your county clerk’s family law division. The clerk stamps both copies, keeps one, and returns one to you for service on the employer. There is no separate filing fee on a IV-D case. Save the stamped copy as proof of filing.
Channel 3: Mail to the Employer. Once the IWO is signed (or self-executing in IV-D cases), mail the IWO to the employer’s payroll department by certified mail with return receipt. There is no fee, but certified mail postage runs about $4–$8. Processing time is dictated by the 7-business-day implementation rule in Fla. Stat. § 61.1301(2)(e). Your proof of service is the green return receipt card.
Channel 4: Federal e-IWO System. State CSE agencies and large employers participate in the federal e-IWO program operated by OCSE. Florida DOR transmits IWOs to participating employers electronically with no fee, and processing is same-day. The proof-of-filing is the e-IWO transaction acknowledgment.
After service, the employer must begin withholding no later than the first pay period that occurs 14 days after receipt and must remit the funds within 2 business days of withholding under 42 U.S.C. § 666(b)(6)(A)(ii).
What Happens After You File
Once the IWO reaches the employer, three timelines start running. First, the employer has 7 business days to send a copy of the IWO to the obligor and to start setting up payroll deductions, per Fla. Stat. § 61.1301(2)(e). Second, the employer must begin withholding on the first pay period that occurs 14 days after receipt. Third, the employer must remit funds to the SDU within 2 business days of each withholding.
The SDU posts received funds within 2 business days and disburses to the custodial parent within 2 more business days, often by direct deposit or the Florida Way2Go Card. Most custodial parents see their first payment within 30 days of the employer receiving the IWO, but high-volume employers like Walmart and Disney often pay within 15 days.
If the obligor changes jobs, the employer must notify the issuing agency within 14 days and return the IWO. If the obligor disputes the IWO, they may file a Motion to Contest Income Deduction within 15 days of receiving notice; however, contesting does not stop the withholding while the motion is pending.
The custodial parent can monitor payments in real time on the Florida Child Support eServices portal, and the obligor can do the same to verify their employer is remitting correctly.
Mistakes to Avoid When Filling Out the Form
The 10 errors below cause the overwhelming majority of rejected Florida IWOs.
- Entering the court case number in the Remittance Identifier box. Money posts to the wrong account or sits in suspense for 30 to 60 days.
- Checking both Original and Amended. The employer rejects the order as unprocessable.
- Using a two-digit year in any date field. Some payroll systems read 26 as 1926 and reject the order.
- Leaving Box 9 (CCPA limit) blank. The employer either defaults to the lowest cap or rejects the order outright.
- Sending payment instructions to the custodial parent’s home address. The remittance violates Florida’s central depository rule and exposes the obligor to duplicate-payment claims.
- Entering monthly amounts in weekly fields. Withholding is off by a factor of 4.33, creating arrears or overpayment.
- Forging or photocopying the issuing official’s signature. The order is void and may trigger sanctions or criminal exposure.
- Using a third-party version of the form. Florida judges and clerks reject non-official PDFs because the page-1 instructions are mandatory.
- Leaving the Document Tracking Identifier blank. The employer cannot match returned funds to the right case and rejects the IWO.
- Listing children who have aged out of support. The employer flags the inconsistency and contacts the sender, delaying first payment by 2 to 4 weeks.
Do’s and Don’ts
Do: – Do download the form fresh each time from the Florida Courts forms page so you always use the current revision. – Do confirm the SDU Depository Number on the SDU portal before entering it as the Remittance Identifier. – Do serve the employer by certified mail with return receipt, because the green card is your only admissible proof of receipt. – Do keep a stamped copy of the IWO in your case file for at least four years, the limitations period for support enforcement claims in Florida. – Do call the SDU at 1-877-769-0251 if you cannot find a Remittance Identifier or are unsure which depository number applies. – Do update the IWO promptly after every modification, because withholding does not auto-adjust.
Don’t: – Don’t post-date the IWO; it is effective on receipt, not the date you write. – Don’t fill the form out by hand if at all avoidable; payroll OCR systems struggle with handwriting and reject illegible IWOs. – Don’t skip the CCPA box, even if you think the obligor’s wages are low enough that the cap will not bind. – Don’t send payment to the custodial parent directly; the SDU is mandatory in Title IV-D cases. – Don’t serve a stale IWO; if more than 30 days have passed since you signed it, regenerate and re-date. – Don’t assume the employer has the underlying order; private filers may need to attach a certified copy on request.
Pros and Cons of Filing on Your Own vs. With Help
Filing 12.917 yourself saves money but exposes you to formatting traps that can delay collection for weeks. Hiring a Florida family law attorney or working with the Florida Department of Revenue Child Support Program costs more but offloads the rejection risk.
Pros of pro se filing: – Cost: zero attorney fees, which can save $300–$1,500 per IWO. – Speed: you control the timeline and can prepare the IWO the same day the order is entered. – Knowledge: you become familiar with your case data and catch errors a busy attorney might miss. – Privacy: you avoid sharing sensitive financial details with another professional. – Direct communication: you talk to the SDU and employer directly, which can shorten resolution time on small issues.
Cons of pro se filing: – Rejection risk: pro se IWOs are rejected at almost double the rate of attorney-prepared IWOs. – Service errors: missing certified mail or skipping the obligor copy can void enforcement of arrears. – Lump sum traps: failing to check the lump sum box on bonuses can let a $20,000 bonus slip through untouched. – Modification confusion: many pro se filers re-issue an Original when they should issue an Amended, doubling the withholding. – Court contempt risk: a defective IWO can be challenged by the obligor, and the court may sanction the filer for procedural abuse.

Yes. It is Florida’s adoption of the federal OMB-0970-0154 Income Withholding for Support form, with Florida-specific routing language added on page 1.
Do I need a judge’s signature on every 12.917?
No. Title IV-D cases authorize immediate withholding by operation of law, and an attorney or DOR caseworker may sign on behalf of the issuing authority.
Can I use 12.917 for alimony only?
Yes. It works for spousal support so long as the alimony is paid through the State Disbursement Unit under section 61.181, Florida Statutes.
What goes in the Remittance Identifier if I do not have a depository number?
No guessing — call the Florida SDU at 1-877-769-0251 and request the depository number for your case before filing.
Do I write my maiden name or married name in the Custodial Party field?
Yes, use the name printed on the underlying support order, even if you have since remarried, unless the order has been formally amended.
Should the Document Tracking Identifier match the Remittance Identifier?
No. They are different fields; the Document Tracking Identifier is your case number, and the Remittance Identifier is the SDU depository number.
Can I list more than six children on the IWO?
Yes, but you must attach a continuation sheet titled Additional Children with the same name and DOB format used in the main table.
Does the obligor get a copy of the IWO?
Yes. The employer must mail or hand-deliver a copy to the obligor within 7 business days of receiving it under Florida law.
Is there a fee to file 12.917 with the clerk?
No in IV-D cases; in non-IV-D enforcement actions a clerk’s fee around $50 may apply under section 28.241.
How long does it take for the first payment to arrive?
Yes, most custodial parents receive their first deposit within 30 days of the employer receiving the IWO, sooner with large payroll providers.
What if the obligor is self-employed?
No standard payroll exists, so the IWO must be served on a 1099 payor or income source identified in discovery, and a separate motion may be needed.
Can the employer charge a fee for processing the IWO?
Yes, Florida law allows employers to deduct up to $5 per payment from the obligor’s remaining wages as an administrative fee under section 61.1301.
What happens if the obligor changes jobs?
Yes, the prior employer must notify the issuing party within 14 days and return the IWO; a new IWO must then be served on the new employer.
Can I email the IWO to the employer?
Yes, if the employer has agreed in advance or participates in the federal e-IWO program; otherwise certified mail is the safest channel.
Does filing 12.917 stop me from going back to court for arrears?
No. Income withholding is one collection tool among several, and you may still pursue contempt, judgment liens, or license suspension for unpaid arrears.
