The COLTAF Enrollment Form is the one-page document a Colorado lawyer or Licensed Legal Paraprofessional (LLP) completes with their bank to open a pooled client trust account, where the interest earned funds legal aid for low-income Coloradans instead of going to the lawyer. You fill out the top half, your bank teller initials and signs the checklist, and one copy goes to the Colorado Lawyer Trust Account Foundation.
This form looks simple, but the details matter because your trust account is tied directly to your law license. A single mistake, like titling the account wrong or using your own Tax ID, can trigger an overdraft report to the Office of Attorney Regulation Counsel. COLTAF distributes millions of dollars in grants each year from the pooled interest on these accounts, so getting your enrollment right helps fund civil legal help across the state. This guide walks you through every line, using the current form posted on COLTAF’s website in October 2025.
Here is what you will learn in this guide:
- 🏦 How to title and open your COLTAF account so it matches Colo. RPC 1.15B word for word
- ✍️ Exactly what to write in every field, with real example entries
- 🔢 Why you use COLTAF’s Tax ID, #74-2250921, and never your own EIN
- 📬 Every way to file the finished form, including the secure remittance portal and the Denver mailing address
- ⚠️ The field-level mistakes that lead to bounced checks, overdraft reports, and discipline
What the COLTAF Enrollment Form Is and Who Must File It
The COLTAF Enrollment Form is the account-opening document that links your bank, you, and the Colorado Lawyer Trust Account Foundation. COLTAF runs Colorado’s Interest on Lawyers’ Trust Accounts (IOLTA) program. When you hold small or short-term client money, that cash sits in a pooled account, and the bank sends the interest to COLTAF rather than to you or the client. COLTAF then turns that interest into grants for civil legal aid.
You must file this form if you hold client or third-party funds that are nominal in amount or expected to be held for a short period of time. Colorado Rule of Professional Conduct 1.15B says all such funds must go into a COLTAF account unless an exception applies. The rule covers every lawyer in private practice in Colorado, and the program now includes Licensed Legal Paraprofessionals (LLPs), the newer license type approved by the Colorado Supreme Court.
The form has three jobs. First, it tells COLTAF a new account exists so the foundation can collect interest. Second, it forces the correct account title and Tax ID at the moment of opening. Third, it creates a teller-signed record proving the account was set up the right way. If you skip this form, your bank may not flag the account as a COLTAF account, and the interest will not reach the foundation, which puts you out of step with the rule.
The account must be held at a bank approved by the Regulation Counsel under Colo. RPC 1.15E. Approved banks agree to report any overdraft on your trust account to attorney regulators. That reporting duty is the main reason your account title and setup must be exact from day one.
Before You Start: Documents and Information You Need
Gather everything below before you walk into the bank or open an account online. Missing one item can stall the opening or force you to redo the form, which delays when COLTAF starts receiving interest.
- Your full legal name as registered with the state. The form must match the name on file with attorney regulation, or COLTAF cannot match the account to you.
- Your Colorado attorney or LLP registration number. This is the unique number that identifies your license; without it, COLTAF cannot tie the account to your record.
- Your law firm’s exact legal name. The account title is built from this, so a wrong or informal name creates a mismatched title.
- Your firm’s mailing address, city, state, and ZIP. COLTAF uses this to send notices, and a bad address means you miss required communications.
- Your firm phone number. This number must print on every trust account check, so have the exact line you want used.
- COLTAF’s Tax ID, #74-2250921. The account is opened under this number, not your EIN, so write it down before you go.
- A government photo ID. The bank needs it to open any account and verify you under federal customer rules.
- A list of approved banks. Confirm your bank is approved by Regulation Counsel so overdraft reporting is in place.
- Your email address (optional but smart). Giving it keeps you on COLTAF’s notice list; skipping it waives your right to certain notices under COLTAF’s bylaws.
Having these ready also helps the teller move fast. Many tellers see this form rarely, so the more complete your information, the smoother the process. Marcus, a new solo attorney in Pueblo, lost an afternoon because he arrived without his registration number and had to drive home to find it.
Where to Get the Form and How to Access It
The official form lives on the foundation’s site as the COLTAF Enrollment Form PDF, posted in October 2025. This is the version this guide follows, and it is the one you should use so your field labels match what regulators expect. Always pull the form from the official source rather than a copy a colleague emailed you, since older copies may carry outdated titling language.
You can also get the form through your bank. Many Colorado banks that offer trust accounts, such as those marketing a legal banking package, keep the COLTAF form on hand and know the program by name. If your banker gives you a blank form, confirm it carries the “COLTAF Trust Account of [Firm Name]” titling instruction and the teller checklist, which are the marks of the current version.
If you cannot find the form or have questions, call COLTAF directly at 303.863.7221, the number printed at the bottom of the form. The staff can confirm which version is current and answer setup questions. You do not need a login or an account to download the PDF; it is free and open to the public.
Print the form single-sided so the teller can initial each checklist item with room to write. If you fill it on a computer first, double-check that the account title field did not auto-correct your firm name. Keep a blank backup copy in case the bank needs one for its own file.
Step-by-Step: How to Fill Out the COLTAF Enrollment Form Line by Line
The form has two main blocks: the Lawyer or Licensed Legal Paraprofessional (LLP) Information section that you complete, and the Financial Institution Information section that you and the teller complete together. Fill in your fields in ink or on screen, then hand the form to the teller for the checklist and signature. Work through the fields in the order they appear below.
1. Lawyer or LLP Name
This field asks for the full legal name of the lawyer or Licensed Legal Paraprofessional opening the account. Write your name exactly as it appears on your registration with the state, last name and first name spelled in full. Jennifer A. Caldwell writes Jennifer A. Caldwell, not Jen Caldwell and not the firm’s name.
If you practice under a middle initial on your registration, include it here so the records line up. A common mistake is writing the firm name in this box instead of a person’s name, which breaks the link between the account and a licensed individual. Some filers think any partner’s name works for a multi-lawyer firm, but you should list the lawyer or LLP who is responsible for the account. The name here is about the person behind the license, not the business entity.
2. Phone Number
This field asks for the phone number where COLTAF and the bank can reach you. Enter a direct, working number, area code first, in a clean format such as (719) 555-0142. Use the line you actually answer, not a fax or a disconnected old office number.
If your firm has one main line, that line is fine here, and it can match the firm phone number that must appear on your checks. The most common error is listing a number that is no longer in service, which means COLTAF cannot reach you about your account. Some people believe this number is only a formality, but it is how the foundation contacts you about interest issues or account questions. Keep it current if your number ever changes.
3. Lawyer or LLP Registration Number
This field asks for your official Colorado attorney or LLP registration number, the unique ID tied to your license. Write the full number with no missing digits, copied straight from your registration record. Jennifer A. Caldwell enters 54321 if that is her registration number.
If you are a newly licensed LLP, use the registration number issued for your LLP license, not a paralegal certificate number. The biggest mistake here is transposing or guessing the digits, which means COLTAF and regulators cannot match the account to the right license. Some filers think the bar association membership number is the same thing, but the registration number is the one assigned through attorney regulation. Double-check it against your official record before you sign.
4. Lawyer or LLP Signature
This field is where you sign to confirm the information you gave is true and that you understand the account rules. Sign in ink, or apply your valid electronic signature if the form is digital, the same way you sign legal documents. Jennifer A. Caldwell signs Jennifer A. Caldwell on this line.
If two lawyers share responsibility for the account, the lawyer named in box 1 should be the one who signs here for consistency. A common mistake is leaving the signature blank or letting staff sign for you, which can make the form invalid and the account opening incomplete. Some people think a typed name counts as a signature on a printed form, but a printed form needs a true handwritten signature. Your signature ties you personally to the account setup.
5. Mailing Address
This field asks for the mailing address where COLTAF should send notices about your account. Enter your firm’s street address or P.O. Box, exactly as mail is delivered to you. Jennifer A. Caldwell writes 1200 Main Street, Suite 4.
If you use a P.O. Box for mail but the bank needs a physical address, give the box here for COLTAF notices and provide the physical address separately to the bank. The common mistake is listing an old office you have since left, which sends your notices to the wrong place. Some filers think email replaces the mailing address, but COLTAF still uses physical mail for many notices. Keep this address current with both COLTAF and the bank.
6. City
This field asks for the city that goes with your mailing address. Spell out the full city name, with no abbreviations. Jennifer A. Caldwell writes Colorado Springs.
If your firm sits in an unincorporated area, use the city your post office assigns to your ZIP. A frequent error is leaving this blank because the street was filled in, which can hold up mail delivery. Some people shorten city names, like writing Co Spgs, but the full name avoids confusion. A complete city line keeps your notices flowing without delay.
7. State
This field asks for the two-letter state where you receive mail. For a Colorado firm, write CO. Use the standard postal abbreviation in capital letters.
If your firm’s mailing address is in a neighboring state but you practice in Colorado, list the state of your actual mailing address here. The common mistake is leaving this blank because it seems obvious, which can still cause a record gap. Some filers spell out Colorado when the form expects the short code, and either is readable, but the two-letter code is cleanest. This small field still matters for clean records.
8. Zip
This field asks for the ZIP code tied to your mailing address. Enter the full five-digit code, or the nine-digit ZIP+4 if you know it. Jennifer A. Caldwell writes 80903.
If your firm recently moved, confirm the new ZIP rather than reusing the old one from memory. The most common mistake is a wrong or partial ZIP, which can misroute COLTAF mail. Some people think the ZIP is optional once the city is listed, but mail systems rely on it heavily. A correct ZIP keeps your account notices arriving on time.
9. Email Address (Optional)
This field asks for an email address so COLTAF can reach you electronically, and it is marked optional. Enter a working email you check often, such as jcaldwell@caldwelllaw.com. The form states that by giving your email you consent to receiving emails from COLTAF.
If you choose to leave it blank, read the warning first: skipping the email waives your right to notice when COLTAF’s bylaws require notice. The common mistake is entering an email you rarely check, which means you miss real notices. Some filers think leaving it blank protects their privacy at no cost, but it actually gives up a notice right. For most filers, providing a monitored email is the safer choice.
10. Financial Institution Name
This field, in the bank section, asks for the name of the bank or credit union holding the account. Write the institution’s full legal name, not a branch nickname. The teller can confirm the exact name, for example Climb Credit Union for those offering a COLTAF account.
If your bank recently merged or rebranded, use the current legal name the bank gives you. The common mistake is writing a branch or shortened name that does not match the bank’s records, which can confuse COLTAF’s matching. Some filers think any bank works, but the account must sit at an institution approved by Regulation Counsel. Confirm approval before you open.
11. Account Name
This field asks for the exact title of the account, and the form is strict: the account must be titled “COLTAF Trust Account of [Firm Name]”. Replace [Firm Name] with your real firm name, so Caldwell Law LLC writes COLTAF Trust Account of Caldwell Law LLC. The form also states you must notify the person opening the account that every check drawn on it must include “COLTAF Trust Account of [Firm Name]” and the firm’s phone number.
If you are a solo with no formal entity name, use the name you practice under, such as COLTAF Trust Account of Jennifer A. Caldwell. The single most damaging mistake on the whole form is mistitling this account, which can mean the bank does not treat it as a COLTAF trust account and the overdraft reporting under Colo. RPC 1.15B fails. Some lawyers think they can add cute or extra wording, and the rule does allow a non-misleading extra designation, but the core phrase must stay intact. Match the format exactly.
12. Account Opening Checklist (Teller-Initialed)
This block is the mandatory checklist, and the form says each item must be initialed by the teller, not by you. The teller initials three statements: that the account was opened with COLTAF’s Tax ID, #74-2250921; that one copy of the form will be sent to COLTAF; and that the account was named using the “COLTAF Trust Account of [Firm Name]” format. Stand with the teller and confirm each line before they initial.
If the teller is unfamiliar with COLTAF, point them to the phone number on the form, 303.863.7221, so they can confirm the steps. The common mistake is using the firm’s or lawyer’s own EIN instead of COLTAF’s Tax ID, which routes interest and tax reporting to the wrong party and breaks the program setup. Some tellers believe the checklist is optional paperwork, but the form states completing it is mandatory. Watch each initial go down before you leave the counter.
13. Teller Name (Printed), Teller Signature, and Date
These fields capture who at the bank opened the account and when. The teller prints their name, signs, and writes the date in a clear format such as 06/02/2026. This is the bank’s certification that the account was opened correctly.
If a personal banker rather than a window teller opens the account, that banker completes these lines. The common mistake is an unsigned or undated teller block, which leaves no proof the bank verified the setup. Some filers think they can sign these lines themselves to speed things up, but only the bank employee may complete them. A complete, dated teller block protects you if a question arises later.
14. Account Number
This field records the new trust account number assigned by the bank. The teller enters the full account number once the account is open, for example 001234567. This number links the form to the live account.
If the bank issues the number after the visit, have them add it before sending the form to COLTAF. The common mistake is leaving this blank, which means COLTAF cannot tie its records to your actual account. Some filers think the account number is sensitive and skip it, but COLTAF needs it to administer the program. Confirm the number is filled in before the form is sent.
Three Filled-Out Examples Using Real Scenarios
Below are three common ways lawyers and LLPs complete this form. Each shows what one named filer enters in the key fields.
Scenario 1: Jennifer, a new solo attorney opening her first trust account
| Form Section | What Jennifer Enters |
|---|---|
| Lawyer or LLP Name | Jennifer A. Caldwell |
| Phone Number | (719) 555-0142 |
| Registration Number | 54321 |
| Mailing Address | 1200 Main Street, Suite 4 |
| City / State / Zip | Colorado Springs / CO / 80903 |
| Email Address (Optional) | jcaldwell@caldwelllaw.com |
| Financial Institution Name | Climb Credit Union |
| Account Name | COLTAF Trust Account of Caldwell Law LLC |
| Tax ID used (teller initials) | #74-2250921 |
| Lawyer Signature | Jennifer A. Caldwell |
Scenario 2: David, a partner moving an established firm’s account to a new bank
| Form Section | What David Enters |
|---|---|
| Lawyer or LLP Name | David R. Okafor |
| Phone Number | (303) 555-7788 |
| Registration Number | 31987 |
| Mailing Address | 455 17th Street, Suite 2200 |
| City / State / Zip | Denver / CO / 80202 |
| Email Address (Optional) | dokafor@okaforpartners.com |
| Financial Institution Name | MidFirst Bank |
| Account Name | COLTAF Trust Account of Okafor & Partners LLP |
| Tax ID used (teller initials) | #74-2250921 |
| Lawyer Signature | David R. Okafor |
Scenario 3: Maria, a newly licensed Licensed Legal Paraprofessional (LLP)
| Form Section | What Maria Enters |
|---|---|
| Lawyer or LLP Name | Maria Elena Vasquez |
| Phone Number | (970) 555-3321 |
| Registration Number | LLP00214 |
| Mailing Address | 88 Mountain View Road |
| City / State / Zip | Fort Collins / CO / 80521 |
| Email Address (Optional) | (left blank, waiving notice) |
| Financial Institution Name | Ent Credit Union |
| Account Name | COLTAF Trust Account of Vasquez Family Law Services |
| Tax ID used (teller initials) | #74-2250921 |
| Lawyer Signature | Maria Elena Vasquez |
In each case, the lawyer or LLP fills the personal and account-title fields, and the teller initials the checklist and signs at the bottom. Note that Maria left her email blank, which the form treats as waiving her right to certain notices. David’s move shows that re-titling at a new bank still uses the same exact format.
How to File the Completed COLTAF Enrollment Form
Once you and the teller finish the form, you must send one copy to COLTAF. The form gives two channels, and you should pick one and keep proof either way.
- By mail. Send one copy to COLTAF at 1120 Lincoln Street, Ste 701, Denver, Colorado 80203. There is no filing fee for enrolling. Use a method you can track, such as certified mail, and keep the receipt as your proof of filing. Allow several business days for delivery and processing.
- By secure remittance portal. You can submit the form through COLTAF’s secure remittance portal, which the form lists as an alternative to mail. There is no fee. Upload a clear scan or photo of the completed, signed form, and save the confirmation screen or email as your proof. Online submission usually reaches COLTAF faster than mail.
For either channel, keep a full copy of the signed form in your own files, along with the bank’s account paperwork. The teller’s signature and the account number should be on the copy you send. If you are unsure which channel your bank prefers, call COLTAF at 303.863.7221 to confirm before you send.
The bank keeps its own copy too, since the teller checklist is part of the account record. Do not assume the bank will send the form for you; the responsibility to send a copy to COLTAF sits with you. Sending promptly matters because it starts the flow of interest to the foundation.
What Happens After You File
After COLTAF receives your form, the foundation logs your account and begins coordinating with your bank so the interest on the pooled funds flows to COLTAF. You will not see this interest, and you have no right or claim to it under Colo. RPC 1.15B. The bank handles the remittance to COLTAF, often monthly, based on the account balance.
Your account is now subject to overdraft reporting because it sits at an institution approved by Regulation Counsel. If the account ever overdraws, the bank reports it to the Office of Attorney Regulation Counsel. That report can lead to questions about how you handle client money, so keep the account reconciled.
From this point, you must follow Colorado’s trust accounting rules every day you hold client funds. That means depositing all nominal or short-term client money into the COLTAF account, keeping client funds separate from your own, and maintaining records. If you ever discover client funds sat in the pooled account long enough to earn meaningful interest for that client, you must request a refund from COLTAF for the client’s benefit, as the rule directs.
If you close the account later or change banks, you set up the new account the same way and send a fresh form. COLTAF will keep your contact information on file using the address and email you provided. Keeping that information current ensures you receive any required notices.
Mistakes to Avoid When Filling Out the Form
- Titling the account without the exact phrase. Leaving out “COLTAF Trust Account of [Firm Name]” can stop the bank from treating it as a trust account and break overdraft reporting.
- Using your own EIN instead of COLTAF’s Tax ID. This routes interest and tax reporting to the wrong party and undermines the whole program setup.
- Writing the firm name in the lawyer name box. This breaks the link between the account and a licensed person, leaving the form incomplete.
- Guessing your registration number. A wrong number means COLTAF and regulators cannot match the account to your license.
- Leaving the teller checklist un-initialed. The form says it is mandatory, so a missing initial makes the account opening record incomplete.
- Signing the teller lines yourself. Only the bank employee may complete them, and a self-signed teller block is invalid.
- Skipping the email without reading the warning. Leaving it blank waives your right to notice under COLTAF’s bylaws.
- Listing an old or wrong mailing address. Your COLTAF notices go to the wrong place, and you miss important communications.
- Leaving the account number blank. COLTAF cannot tie its records to your live account without it.
- Opening at a non-approved bank. Without an approved institution, the required overdraft reporting under the rules is not in place.
- Forgetting the firm phone number on checks. The form requires it on every check, and missing it conflicts with the titling instruction.
- Assuming the bank sends the form to COLTAF. The duty to send a copy is yours, and skipping it means COLTAF never logs your account.
Do’s and Don’ts
Do:
- Do copy your name and registration number from your official record, because exact matches keep your account tied to your license.
- Do title the account exactly as “COLTAF Trust Account of [Firm Name]”, since the form and the rule both demand it.
- Do confirm the teller uses COLTAF’s Tax ID, #74-2250921, because the program depends on it.
- Do provide a monitored email, so you keep your right to COLTAF notices.
- Do keep a signed copy and your proof of filing, in case a question comes up later.
- Do call COLTAF at 303.863.7221 when unsure, because the staff can confirm the current process.
Don’t:
- Don’t use a nickname or informal firm name, because a mismatched title can break trust account treatment.
- Don’t sign the teller’s lines, since only the bank employee may complete them.
- Don’t open the account at a bank you have not confirmed is approved, because overdraft reporting may not apply.
- Don’t leave the account number off the copy you send, as COLTAF needs it to log the account.
- Don’t assume the bank files the form for you, because the duty to send it is yours.
- Don’t reuse an outdated form copy, since older versions may carry wrong titling language.
Pros and Cons of Opening on Your Own vs. With Help
Many lawyers open a COLTAF account directly at the bank, while others lean on a banker who handles legal accounts often. Here is how the two paths compare.
| Opening on Your Own | Opening With a Legal-Banking Banker |
|---|---|
| Faster if you already know the rules, because you control the timing | Slower to schedule, but the banker often knows COLTAF by name |
| Free, with no advisor cost, so you save money | May come bundled with a legal banking package and added services |
| Full control over the exact account title you enter | The banker double-checks the title, lowering the risk of a mismatch |
| You carry all the risk of a setup mistake | Shared review reduces the chance of using the wrong Tax ID |
| Good for a confident solo who has done it before | Better for a first-timer who wants the checklist handled smoothly |
Pros of opening on your own: you save money, you move on your own schedule, you keep direct control of the title, you learn the process firsthand, and you avoid waiting on an appointment.
Cons of opening on your own: you carry the full risk of a titling or Tax ID error, you may face a teller unfamiliar with COLTAF, you have no second reviewer, you may misread the email-waiver line, and you may need to redo the form if something is wrong.
Key Entities That Interact With This Form
Several organizations and rules connect to your COLTAF account, and knowing each helps you stay compliant.
- COLTAF. The foundation that runs Colorado’s IOLTA program and turns pooled interest into legal aid grants; it receives your form and the interest.
- Office of Attorney Regulation Counsel. The body that oversees lawyer conduct and receives overdraft reports on trust accounts; setup mistakes can land here.
- Colo. RPC 1.15B. The rule that requires the trust account, sets the COLTAF account definition, and directs that interest goes to COLTAF.
- Colo. RPC 1.15E. The rule under which banks are approved to hold trust accounts and agree to report overdrafts.
- Your approved bank or credit union. The institution that opens the account, remits interest, and reports any overdraft.
These pieces work together. The rules require the account, COLTAF collects the interest, the approved bank reports problems, and the regulator steps in if funds are mishandled. Your enrollment form is the document that starts this chain.
FAQs
Do I use COLTAF’s Tax ID or my own EIN to open the account? Yes. You open the account with COLTAF’s Tax ID, #74-2250921, exactly as the teller checklist states. Using your own EIN routes interest and tax reporting to the wrong party.
Do I have to title the account a specific way? Yes. The account must be titled “COLTAF Trust Account of [Firm Name]”. This exact phrase lets the bank treat it as a trust account and keeps overdraft reporting working.
Do I write my own name or my firm’s name in the first box? No. The first box asks for the lawyer or LLP name, so you write a person’s name, not the firm. The firm name appears in the account title field instead.
Do I have to give my email address on the form? No. The email is optional, but leaving it blank waives your right to notice when COLTAF’s bylaws require notice. A monitored email is usually the safer choice.
Do I sign the teller’s lines if the teller is busy? No. Only the bank employee may print, sign, and date the teller block. A self-signed teller section makes the form invalid.
Do I, or the bank, send the form to COLTAF? Yes. You are responsible for sending one copy to COLTAF, by mail or the secure portal. Do not assume the bank will send it for you.
Do Licensed Legal Paraprofessionals (LLPs) use this same form? Yes. The form names both lawyers and LLPs, and LLPs use their own registration number. The rest of the fields work the same way.
Do I have to use an approved bank? Yes. Under the rules, the account must sit at a bank approved by Regulation Counsel so overdraft reporting is in place. Confirm approval before opening.
Do I keep any interest earned on the account? No. Interest on a COLTAF account goes to the foundation, and you and your firm have no right or claim to it under Colo. RPC 1.15B.
Do I need to put my phone number on my trust account checks? Yes. The form requires every check to include “COLTAF Trust Account of [Firm Name]” and the firm’s phone number. Missing either conflicts with the titling rule.
Do I have to fill in the account number myself? No. The bank assigns and enters the account number once the account is open. Confirm it is filled in before the form is sent to COLTAF.
Do I pay a fee to file this form with COLTAF? No. There is no filing fee to enroll, whether you mail the form or use the secure remittance portal. Keep your proof of filing either way.
Do I file a new form if I switch banks? Yes. Each new account needs its own form, titled the same exact way, with the new bank’s information and a fresh teller signature.
Do I need to provide my registration number if I just got licensed? Yes. Even new attorneys and LLPs have a registration number, and you must enter it. Use the number tied to your license, not a prior certificate number.
