Yes, you can fill out California Form GC-110 yourself by listing the conservatee’s or ward’s information, identifying the bond amount you want the court to approve, attaching the surety bond, and filing it with the probate clerk in the county where the case is pending. The form is the Bond filing used by conservators, guardians, personal representatives, and trustees to post the security the court ordered before they can act on behalf of someone else’s money.
If you skip this step, the court can suspend your powers, refuse to issue Letters, surcharge you for losses, or remove you entirely under California Probate Code § 2334. According to the Judicial Council of California 2024 Court Statistics Report, more than 38,000 probate, conservatorship, and guardianship cases are filed each year in California, and bond defects are among the top three reasons clerks reject filings at intake.

What Is California Form GC-110?
California Form GC-110 is the Bond form used in probate, conservatorship, and guardianship cases. The Judicial Council adopted this form so fiduciaries can file proof of the surety bond the court ordered before they begin handling someone else’s money. The form is mandatory in conservatorship and guardianship matters and is used in many decedent estate matters as well, depending on the local rule and the size of the estate.
A bond is a type of insurance policy that pays the conservatee, ward, or estate if the fiduciary steals, loses, or wastes the assets. The court sets the amount based on the value of the personal property plus one year of estimated income, as required by Probate Code § 2320(c). If you fail to file a proper bond, the consequence is direct: the clerk will not issue Letters, and you have no legal authority to act.
A common misconception is that GC-110 is only for conservators and guardians. In fact, executors and administrators can use the same form when local rules require it, although Form DE-150 is the related Letters form they will receive after the bond is approved. For a quick scenario, picture Maria, a newly appointed conservator for her mother. The court orders a $250,000 bond at the hearing, and Maria has 30 days to file GC-110 with an attached surety bond, or the court can revoke her appointment under Probate Code § 2320(b).
Why the Court Requires a Bond
Bonds protect vulnerable people from theft and mismanagement. The California Legislature created the bond rule because conservatees and minors cannot watch their own money, and even honest fiduciaries make costly errors. The bond shifts the risk of loss from the protected person to the surety company, which then has the right to sue the fiduciary for repayment.
If you ignore the bond order, the court can suspend your powers under Probate Code § 2334, appoint a successor, and surcharge you personally for any loss. The consequence reaches your own bank account, not just the estate. A real example is David, an executor who waited six months to post bond after his mother’s death; the court removed him and ordered him to repay $42,000 in lost rental income.
A common misconception is that close family members never need a bond. While Probate Code § 8481 lets a will waive bond, the court can still require one if the judge finds it necessary to protect heirs or creditors. The court’s job is protection, not convenience.
Who Must File GC-110
Conservators of the estate, guardians of the estate, executors, administrators, and some trustees must file GC-110 when the court orders a bond. Conservators and guardians of the person only generally do not need a bond because they do not handle money, but the judge can still require one in unusual cases. Public guardians and trust companies are usually exempt under Probate Code § 2321.
The consequence of filing the form when you do not need to is wasted time and a possible rejection notice from the clerk. The consequence of not filing when you do need to is far worse, including denial of Letters and personal liability. A clear example is Janet, a guardian of her nephew’s $80,000 personal injury settlement; she must post bond before she can withdraw a single dollar, even for school clothes.
A common misconception is that small estates avoid bond. While Probate Code § 13100 creates a small estate affidavit shortcut, that procedure does not use Letters at all, so GC-110 does not apply. Once you open a formal probate, the bond rules kick in.
Step-By-Step: How to Fill Out Form GC-110
Form GC-110 has a caption block, six numbered items, two signature lines, and a notary acknowledgment. You complete it after the court signs the order appointing you and setting the bond amount. You then take the form to a licensed surety company, which fills in the surety side and signs.
The form follows the Judicial Council’s standard caption rules at California Rules of Court Rule 2.100. You print or type all entries, never handwrite in cursive, and use black ink only. Errors get the form bounced at the clerk’s window, which delays your appointment by weeks.
A common misconception is that you can file GC-110 before the appointment hearing. You cannot, because the court has not yet set the bond amount. The consequence of premature filing is a clerk rejection and a wasted notary fee.
Caption Block: Attorney and Court Information
The top-left box asks for your name, address, phone, email, and State Bar number if you are an attorney. Self-represented filers write Self-Represented on the State Bar line. The top-right box is for the clerk’s stamp, so leave it blank.
The next block asks for the Superior Court of California, County of [____], plus the court’s street address and branch name. Use the exact county and branch where your case is pending, because filing in the wrong branch can void the bond filing under local rules like Los Angeles Superior Court Local Rule 4.3. The consequence of using the wrong branch is rejection or transfer, which costs you both time and filing fees.
A real example is Robert, who filed his Riverside conservatorship bond at the Indio branch instead of the Riverside branch. The clerk rejected it, and his $400 surety premium clock kept ticking while he refiled. A common misconception is that any branch in the county will do; many counties have strict probate venue rules.
Item 1: Conservatee, Ward, or Decedent’s Name
Item 1 asks for the name of the conservatee, ward, or decedent. Use the exact name shown on the petition and order, including middle initials and any aka (also known as) names. Mismatched names cause the surety to refuse to bind coverage because the bond must match the court order word for word.
The consequence of a name mismatch is that the surety voids the bond, which then leaves you with no coverage even though you paid the premium. A real example is Linda, who wrote Robert Smith on GC-110 when the order said Robert J. Smith Sr.; her surety canceled the bond, and she had to pay a second premium to fix it.
A common misconception is that a casual name is fine because everyone knows who you mean. The court and the surety are not casual, so spell every letter the same way.
Item 2: Type of Fiduciary
Item 2 has check boxes for conservator of the estate, guardian of the estate, executor, administrator, administrator with will annexed, special administrator, and trustee. You check only one box that matches your appointment order. If you serve in two roles, such as conservator of both the person and estate, you only check the role that requires the bond, which is the estate role.
The consequence of checking the wrong box is that the surety underwrites the wrong risk, and the court may treat the bond as defective under Probate Code § 2320. A real example is Carlos, who checked trustee when he was actually the administrator with will annexed; the surety canceled coverage on day one.
A common misconception is that executor and administrator are interchangeable. They are not. An executor is named in the will, while an administrator is appointed when there is no will or no named executor.
Item 3: Bond Amount
Item 3 is the dollar amount of the bond, which must match the amount in the appointment order. The judge sets the amount based on personal property value plus one year of estimated gross income from real and personal property, per Probate Code § 2320(c)(1). If your case involves blocked accounts, the bond amount drops to cover only the unblocked assets, as explained in California Rules of Court Rule 7.207.
The consequence of writing the wrong number is direct rejection by the clerk and possible removal if you act before correcting it. A real example is Patricia, a guardian who wrote $50,000 instead of $150,000; the court issued an order to show cause and held her in contempt for nine days.
A common misconception is that you can round up to be safe. You cannot, because the bond must match the order exactly down to the dollar. Surety premiums are based on the bond amount, so rounding up also costs you more.
Item 4: Sureties and Bond Type
Item 4 identifies the surety company or the personal sureties who guarantee the bond. Most filers use a corporate surety licensed by the California Department of Insurance, because corporate sureties are accepted by every court. Personal sureties are allowed under Probate Code § 2322, but they must be California residents, own real property worth twice the bond, and file a Justification of Surety form.
The consequence of choosing an unlicensed surety is automatic rejection and possible fraud charges if the surety is fake. A real example is Anthony, who used an out-of-state personal surety; the court rejected the bond and gave him 10 days to refile or face removal.
A common misconception is that personal sureties save money. They rarely do, because the justification process costs more in attorney time than a corporate surety premium of about 0.5% of the bond amount per year, per the Surety & Fidelity Association of America 2025 rate guide.
Item 5: Single or Several Sureties
Item 5 asks whether the bond is a single corporate surety bond or a several (joint) bond with multiple personal sureties. Single is the default for corporate bonds. Several requires each personal surety to sign and to justify worth.
The consequence of misclassifying the bond is that the court treats it as defective and demands a corrected filing. A real example is Susan, who used two personal sureties but checked single; the clerk rejected it, and she paid for a new notary appointment.
A common misconception is that several means multiple optional sureties. It actually means jointly and severally liable, which is a legal term meaning each surety is on the hook for the full amount.
Item 6: Effective Date
Item 6 is the date the bond becomes effective, which must be on or after the appointment order date. Backdating is fraud. Most surety companies set the effective date as the date of issue and renew annually.
The consequence of a gap between the appointment date and the bond effective date is that any acts you took during the gap were unauthorized, exposing you to surcharge under Probate Code § 2540. A real example is Michael, who let his bond lapse for 30 days; the court surcharged him $8,500 for unauthorized rent collection.
A common misconception is that the bond is good forever once issued. It is not, because most bonds renew yearly, and you must pay the premium on time or face cancellation.
Signature, Notary, and Surety Blocks
The bottom of the form has signature lines for you (the principal) and for the surety. Both signatures must be notarized, per Probate Code § 2320(b) and California Civil Code § 1189. The notary uses the standard California acknowledgment wording, never an out-of-state form.
The consequence of a missing or wrong notary is rejection at the clerk’s window. A real example is Kevin, whose surety used a Nevada notary acknowledgment; the clerk bounced it, and Kevin lost three days fixing the problem.
A common misconception is that an electronic signature is fine. While California Government Code § 8205 permits remote online notarization since 2024, many counties still require wet-ink signatures on bonds, so check your local rule first.
Three Real-World Scenarios
Each scenario below shows a typical GC-110 filing and the legal consequence of one decision. The tables compare the step taken to the result. These scenarios are based on patterns reported in the California Courts Self-Help Probate Guide.
Scenario 1: Conservator of the Estate
Maria is appointed conservator of her mother’s $400,000 estate. The judge sets bond at $440,000, covering assets plus one year of $40,000 estimated income.
| Step Maria Takes | Legal Result |
|---|---|
| Files GC-110 with corporate surety bond for $440,000 | Court issues Letters of Conservatorship; Maria can act |
| Forgets to attach the bond document itself | Clerk rejects the filing; Maria must refile and re-pay the notary |
| Blocks $300,000 in a court-blocked account under Probate Code § 2328 | Bond drops to $140,000, saving $1,500 in annual premium |
Scenario 2: Guardian of a Minor’s Estate
Janet is guardian of her 10-year-old nephew’s $80,000 settlement. The judge orders a bond of $84,000.
| Step Janet Takes | Legal Result |
|---|---|
| Posts $84,000 corporate surety bond on GC-110 | Court issues Letters of Guardianship; Janet can manage funds |
| Lets the bond lapse in year three | Court suspends Janet under Probate Code § 2334 |
| Files annual accounting on Form GC-405 on time | Court approves accounting; bond stays in force |
Scenario 3: Executor of a Decedent’s Estate
David is executor of his mother’s $600,000 estate. The will waives bond, but two heirs object.
| Step David Takes | Legal Result |
|---|---|
| Asks the court for bond waiver despite objection | Court denies waiver and orders $660,000 bond |
| Files GC-110 with corporate surety on time | Court issues Letters Testamentary; David can sell the house |
| Misses the 30-day filing deadline | Court revokes appointment; successor administrator takes over |
Bond Calculation: The Numbers Behind Item 3
The bond amount in Item 3 is not random. The Probate Code requires a specific formula, and getting it wrong leads to either an under-secured estate or a wasted premium. Personal injury settlements, ongoing rental income, and royalty streams all change the calculation.
The § 2320 Formula
Probate Code § 2320(c) sets the formula as the value of personal property plus the probable annual gross income from real and personal property, plus a reasonable allowance for cost of recovery, including attorney fees. Real property itself is not counted because the court controls sales through Form DE-260. The cost-of-recovery allowance is usually 10% of the base amount.
The consequence of using the wrong formula is that the bond is too low, and the surety has a defense if it later refuses to pay a claim. A real example is Tom, an executor who left out the $30,000 royalty income from his father’s book; the bond was short, and the heirs sued Tom personally for the gap.
A common misconception is that you add real property at full value. You do not, because real estate stays under court control until you sell it, and the proceeds go into a blocked account.
Reductions for Blocked Accounts
You can lower the bond by depositing cash or securities into a court-blocked account under California Rules of Court Rule 7.207. The financial institution signs Form MC-356 (Receipt and Acknowledgment of Order for the Deposit of Money Into Blocked Account), and the bond drops dollar-for-dollar.
The consequence of blocking funds is that you cannot touch them without a court order. A real example is Susan, a guardian who blocked her ward’s $200,000 settlement; she had to file Form MC-358 every time she needed money for orthodontics.
A common misconception is that blocked accounts are a hassle worth avoiding. The truth is that blocking $200,000 saves about $1,500 a year in surety premium, which adds up over a long conservatorship.
Premium Costs and Surety Underwriting
Corporate surety premiums in California average 0.5% to 0.8% of the bond amount per year for fiduciaries with strong credit, per the Surety & Fidelity Association rate guide. Filers with weaker credit may pay 1% to 3%, and some sureties refuse to underwrite filers with bankruptcies in the last seven years.
The consequence of poor credit is either a denial or a higher rate, which the estate ultimately pays. A real example is Brian, an executor with a recent Chapter 13 filing; he paid $4,800 a year on a $200,000 bond, while a clean-credit filer would have paid $1,200.
A common misconception is that the estate cannot pay the premium. It can, because Probate Code § 2640 treats bond premiums as an allowable expense of administration.
Filing, Service, and Hearing Logistics
Filing GC-110 is more than handing it to the clerk. You must serve interested parties, calendar renewal dates, and respond to objections. Each step has its own rules.
Where and How to File
You file the original signed and notarized GC-110 with the probate clerk in the county where your case is pending. Most counties accept e-filing through providers listed on the California Courts e-Filing portal. Some, like Los Angeles, require e-filing for represented parties under Local Rule 3.4.
The consequence of filing in the wrong county is dismissal or transfer, which restarts the clock. A real example is Helen, who filed her San Diego case in Orange County; the clerk transferred it, and Helen lost two months. A common misconception is that filing fees apply to GC-110 itself; they do not, because the bond is part of the appointment process and the original filing fee covered it.
Notice Requirements Under § 1220
Probate Code § 1220 requires 15 days’ written notice to interested parties before any hearing on bond changes, including increases, decreases, or waivers. You serve a copy of the petition and the proposed GC-110 amount. The notice must include the hearing date, time, and department.
The consequence of skipping notice is that any order is void and can be challenged years later. A real example is Frank, an administrator who increased bond without notice; the heirs successfully reopened the estate three years later. A common misconception is that informal notice by text is enough; it is not, because the statute requires written notice by mail.
Renewals, Riders, and Exoneration
Most bonds renew annually, and the surety sends a continuation certificate you must keep with the court file. If the estate value changes, you file a rider increasing or decreasing the bond. When the case ends, you file a petition to exonerate the bond using Form GC-070 for guardianship or DE-295 for decedent estates.
The consequence of forgetting exoneration is that you keep paying premium long after the case closes. A real example is Patricia, who paid $1,200 a year for four years after her conservatee died; she finally exonerated the bond and got no refund. A common misconception is that the bond ends automatically when the case closes; it does not, because the surety remains liable until the court signs an exoneration order.
Mistakes to Avoid on GC-110
Bond filings are technical, and small errors create big consequences. The list below covers the seven most common mistakes reported by California probate examiners and the California Probate Referees Association.
- Mismatched names: Writing Bob Smith when the order says Robert J. Smith Sr. voids the surety contract and forces a refile.
- Wrong bond amount: Rounding $440,000 up to $450,000 triggers clerk rejection because the form must match the order exactly.
- Premature filing: Filing GC-110 before the judge signs the appointment order is a wasted trip because the bond amount is not yet set.
- Out-of-state notary: Using a Nevada or Arizona acknowledgment fails California Civil Code § 1189 and gets the bond rejected.
- Missing surety license: Using an unlicensed or out-of-state-only surety violates Probate Code § 2320 and exposes you to fraud charges.
- Lapsed renewal: Letting the bond expire mid-case suspends your powers under Probate Code § 2334 and triggers personal surcharge.
- No proof of service: Filing without serving interested parties under Probate Code § 1220 makes the order voidable on appeal.
- Forgetting blocked accounts: Skipping the Rule 7.207 reduction wastes thousands in unnecessary surety premium over the life of a long case.
Do’s and Don’ts of Filing GC-110
Following these rules keeps your case moving and protects you from personal liability. Each item ties to a specific Probate Code section or local rule.
Do’s
- Do match every name and dollar amount exactly to the appointment order, because the surety contract follows the order.
- Do use a corporate surety licensed by the California Department of Insurance, because corporate bonds are accepted in every county.
- Do block large cash assets under Rule 7.207 to lower bond and save premium dollars.
- Do calendar the annual renewal date, because lapsed bonds suspend your powers under Probate Code § 2334.
- Do serve all interested parties at least 15 days before any hearing, as required by Probate Code § 1220.
- Do keep a certified copy of the bond and the continuation certificate in your case file for every accounting cycle.
Don’ts
- Don’t sign GC-110 before the surety fills out its side, because incomplete forms get bounced at intake.
- Don’t use a personal surety unless you confirm California residency and double-the-bond real property under Probate Code § 2322.
- Don’t assume the will’s bond waiver is final, because the court can override it under Probate Code § 8481.
- Don’t backdate the effective date, because that is fraud and voids the bond entirely.
- Don’t skip the notary acknowledgment, because Civil Code § 1189 requires it for all sworn filings.
- Don’t forget to exonerate the bond at the end of the case, because the premium clock keeps ticking until the court signs the exoneration order.
Pros and Cons of Different Bond Strategies
Choosing between a corporate surety, a personal surety, blocked accounts, and bond waiver each has trade-offs. The list below highlights the most important pros and cons.
Pros of Corporate Surety Bonds
- Speed: Corporate sureties underwrite in 24 to 48 hours, so you can post bond fast.
- Acceptance: Every California probate court accepts a licensed corporate surety without extra justification.
- Cost predictability: Premiums are set at 0.5% to 0.8% of the bond amount, so you can budget the estate expense in advance.
- Renewal automation: Sureties send continuation certificates yearly, which keeps you in compliance under Probate Code § 2334.
- Liability shield: The surety pays first when there is a covered loss, then pursues the fiduciary, which protects heirs from delay.
Cons of Corporate Surety Bonds
- Annual premium: A $500,000 bond costs about $2,500 a year, which the estate must pay until exoneration.
- Credit checks: Sureties pull personal credit and may deny applicants with bankruptcies or judgments.
- Indemnity agreement: You sign a personal indemnity, meaning the surety can sue you personally if it pays a claim.
- Underwriting delays: Complex estates with foreign assets can take two to three weeks to bind, slowing appointment.
- Cancellation risk: The surety can cancel with 30 days’ notice if your credit drops, leaving you scrambling for a replacement.
Key Entities Involved in a GC-110 Filing
Several people and organizations play a role in the bond process. Knowing each role helps you anticipate every step.
The fiduciary is the conservator, guardian, executor, administrator, or trustee posting the bond. The surety is the corporate insurance company or personal sureties guaranteeing performance. The court is the Superior Court of California probate department in your county, which sets the bond and approves the form.
The probate examiner is the court staff member who reviews GC-110 before the hearing and writes pre-grants or notes of defects. The probate referee is a state-appointed appraiser who values non-cash assets, which feeds into the bond calculation under Probate Code § 8901. The interested parties are heirs, beneficiaries, conservatees, and creditors who have notice rights under Probate Code § 1220.
Recap of Key Court Rulings
California courts have shaped the bond rules through published opinions. The cases below show how judges enforce GC-110 and the underlying statutes.
In Estate of Bonaccorsi (1999) 69 Cal.App.4th 462, the court ruled that an executor who failed to post bond after the court rejected a will waiver was personally liable for losses caused by the delay. The consequence is that you cannot rely on a will waiver if the court overrides it.
In Conservatorship of Lewis (2010) 184 Cal.App.4th 197, the court held that an undisclosed bond reduction stipulation between the conservator and a beneficiary was invalid without court approval and proper notice. The consequence is that bond changes always require a hearing.
In Estate of Kampen (2011) 201 Cal.App.4th 971, the court emphasized that surcharge for a lapsed bond is strict liability, meaning the fiduciary’s good faith is no defense. The consequence is that calendaring is everything in long-running probate cases.
Frequently Asked Questions
Do I need a lawyer to file Form GC-110?
No, you do not need a lawyer to file Form GC-110, but most self-represented filers benefit from one because surety underwriting and notice rules are technical and small errors cause costly delays.
Can a will waive the bond requirement?
Yes, a will can waive bond under Probate Code § 8481, but the court can still order a bond if heirs object or the judge finds it necessary to protect the estate.
Does GC-110 apply to small estates under $184,500?
No, small estates handled by the Probate Code § 13100 affidavit do not use Letters and therefore do not require a bond or GC-110 filing.
How fast can I get a corporate surety bond?
Yes, most California-licensed sureties bind coverage in 24 to 48 hours for filers with strong credit, though complex estates or weak credit can stretch underwriting to two or three weeks.
Can I lower my bond by using a blocked account?
Yes, blocking cash or securities in a court-controlled account under Rule 7.207 reduces the bond dollar-for-dollar, and the financial institution files Form MC-356.
Do conservators of the person need a bond?
No, conservators of the person only generally do not need a bond because they do not handle money, but the court can still require one in unusual cases involving litigation or settlements.
What happens if my bond lapses?
Yes, a lapsed bond triggers automatic suspension under Probate Code § 2334, and the court can remove you and surcharge you for any losses during the gap.
Can the estate pay the bond premium?
Yes, Probate Code § 2640 treats surety premiums as ordinary administration expenses, so the estate reimburses the fiduciary at the next accounting.
Are personal sureties allowed in California?
Yes, personal sureties are permitted under Probate Code § 2322, but each must be a California resident owning real property worth twice the bond amount.
Do I have to refile GC-110 every year?
No, you do not refile the form every year, but the surety files an annual continuation certificate, and the court can order an updated bond if the estate value changes.
Can interested parties object to the bond amount?
Yes, any interested party can object under Probate Code § 1043, and the court will hold a noticed hearing under the § 1220 15-day rule.
How do I exonerate the bond at the end of the case?
Yes, you exonerate the bond by filing a petition for final discharge using Form GC-070 for guardianship or Form DE-295 for decedent estates after final accounting approval.
