California Form GC-140, Letters of Guardianship, is the one-page court order that gives a guardian the legal power to act for a minor’s person, estate, or both, and you fill it out by entering the minor’s name, the guardian’s name, the guardianship type, and any special powers granted by the judge, then filing it with the superior court clerk for the judge’s signature and the clerk’s seal. The form is published by the Judicial Council of California and used statewide under Probate Code section 2310.
Without signed and sealed Letters, a guardian has no authority to enroll a child in school, consent to medical care, open a blocked account, or sell estate property. According to the Judicial Council’s 2024 Court Statistics Report, California superior courts processed more than 8,400 new probate guardianship petitions in fiscal year 2022–2023, and every single approved case ended with a GC-140 issuance.

What Form GC-140 Is and Why It Exists
Form GC-140 is the official Letters of Guardianship under California Rules of Court, rule 7.101. It is the document the court hands the guardian to prove appointment to schools, hospitals, banks, landlords, and the Social Security Administration. Without it, third parties have no legal duty to follow the guardian’s instructions.
The form exists because Probate Code section 2311 requires the clerk to issue Letters once the guardian qualifies by filing the bond (if any) and signing the Form GC-150 Duties of Guardian Acknowledgment. The Letters then trigger the guardian’s fiduciary duties under Probate Code section 2401.
A common misconception is that the Order Appointing Guardian (Form GC-240) is the same as Letters. The Order is the judge’s ruling that you may serve. The Letters are your proof of authority. You need both, and most institutions ask only for the Letters.
The consequence of acting before Letters issue is severe. Contracts signed without Letters are voidable, medical consents may be ignored, and the would-be guardian can be personally liable. In Conservatorship of Pelton (1982) 132 Cal.App.3d 496, the court reaffirmed that a fiduciary’s authority begins only when Letters issue, not when the order is signed.
A real-world example: Maria Hernandez of Fresno is named guardian of her niece on March 1, but the bond is not posted until March 14. Maria cannot legally sign a school enrollment form on March 5, even though the judge already ruled in her favor.
Person, Estate, or Both
GC-140 supports three guardianship types. Guardianship of the person covers custody, schooling, and medical care under Probate Code section 2351. Guardianship of the estate covers money and property under Probate Code section 2400. A combined guardianship covers both.
The consequence of checking the wrong box is that the bank, school, or hospital will refuse to act. A person-only guardian cannot withdraw from a blocked account. An estate-only guardian cannot sign a surgical consent. The mistake forces a return to court for amended Letters, costing weeks.
A common misconception is that “guardianship of the person” includes the right to spend the child’s inheritance. It does not. If the minor receives more than $5,000, Probate Code section 3401 requires a separate estate guardianship or a blocked account.
For example, James Carter of San Diego is appointed guardian of the person of his 10-year-old grandson. When the boy inherits $40,000 from a deceased parent, James must petition again for guardianship of the estate before the funds release. The first GC-140 alone is not enough.
Before You Touch GC-140: The Filing Packet
GC-140 is the last form issued, not the first filed. You first complete the petition packet under California Rules of Court, rule 7.1001. The packet drives whether GC-140 ever gets signed.
The core forms include the GC-210(P) Petition for Appointment of Guardian of Person, the GC-210(CA) Confidential Guardian Screening Form, the GC-110 Notice of Hearing, the GC-211 Confidential Guardian Information, and the ICWA-010(A) Indian Child Inquiry Attachment under the Indian Child Welfare Act, 25 U.S.C. § 1901.
The consequence of missing any one form is a clerk rejection or a continued hearing. Los Angeles Superior Court’s self-help guardianship page reports that incomplete packets are the top reason for first-hearing continuances.
A common misconception is that you can file GC-140 yourself, blank, and the clerk will fill it in. The clerk will not. You prepare GC-140 in advance, leave the signature and seal blocks empty, and present it after the judge signs the GC-240 order.
For example, Aisha Robinson of Alameda County brings a perfectly drafted GC-140 to her hearing. The judge signs GC-240, and the clerk issues GC-140 the same afternoon. Tom Nguyen in Orange County forgets to bring GC-140; he must mail it in and waits eleven days for issuance.
County Local Rules
Each county adds local nuances. Los Angeles Local Rule 4.124 requires a courtesy copy lodged seven days before the hearing. San Diego Local Rule 4.16.4 requires the proposed guardian to attend an orientation. Sacramento Local Rule 8.06 requires fingerprinting through Live Scan.
The consequence of ignoring a local rule is continuance, sanctions under Code of Civil Procedure section 177.5, or denial. Local rules sit on top of the Probate Code, never below.
A common misconception is that statewide Judicial Council forms preempt local rules. They do not. California Rules of Court, rule 3.20 limits local form requirements but allows local procedural rules.
Line-by-Line: How to Fill Out Form GC-140
The current revision is January 1, 2008, and you can download the fillable PDF from the Judicial Council forms page. Type, do not handwrite, except for signatures.
Caption Block (Top of Page 1)
The caption asks for the attorney or self-represented party, the court, and the case caption. Enter the petitioner’s name, mailing address, and phone number under “Attorney or Party Without Attorney.” If you have no lawyer, write In Pro Per in the attorney name field per California Rules of Court, rule 1.20.
The consequence of a wrong address is that court notices go astray. Under Probate Code section 1212, missed notice can void later orders. Always match the address to the petition exactly.
A common misconception is that you can use a P.O. box. Most counties accept it for mailing but require a physical residence elsewhere on the petition. Use both if asked.
For example, Linda Park in Santa Clara writes her Cupertino home address in the caption. She lists the same address on GC-210(P). The clerk accepts both without issue.
Court Branch and Case Number
Enter the superior court branch (e.g., “Superior Court of California, County of Los Angeles, Stanley Mosk Courthouse”). Add the case number assigned at petition filing. Leave blank only if filing GC-140 simultaneously with the petition, which is rare.
The consequence of a wrong branch is rejection at the filing window. Probate is heard only in designated branches; in Los Angeles, that is Stanley Mosk under LASC General Order 2023-GEN-013-00.
A common misconception is that any superior court branch in the county will do. It will not. Probate filings go to the assigned probate hub.
Guardianship of (Name of Minor)
Enter the minor’s full legal name exactly as it appears on the birth certificate. If the minor uses a different surname day-to-day, list both: “Sofia Maria Gonzalez, also known as Sofia Lopez.”
The consequence of a name mismatch is that schools and SSA may refuse the Letters. Identity must match the birth certificate to satisfy 42 U.S.C. § 666 state recordkeeping rules.
A common misconception is that you may shorten the middle name to an initial. Probate practice favors the full name. Banks and Social Security flag mismatches under their Customer Identification Program rules in 31 C.F.R. § 1020.220.
For example, Carlos Rivera lists his ward as “Diego A. Rivera” on GC-140. Wells Fargo refuses to open a blocked account because the birth certificate reads “Diego Antonio Rivera.” Carlos must amend the Letters.
Item 1: Appointment
Item 1 states that the named person is appointed guardian. Check the box for Person, Estate, or both, mirroring the petition. If the appointment is temporary, you must use Form GC-150 Letters of Temporary Guardianship, not GC-140.
The consequence of checking Estate without bond is that the clerk will not issue Letters under Probate Code section 2320. Bond protects the ward from fiduciary loss.
A common misconception is that family relationship waives bond. It does not unless the judge expressly waives it under Probate Code section 2321 and the will or trust instrument allows.
For example, Patricia Wong of San Francisco posts a $50,000 bond before estate Letters issue. Her sister, Jennifer Wong in Contra Costa, asks for bond waiver because the funds will be in a blocked account. The judge grants the waiver under Probate Code section 2328.
Item 2: Special Powers (Person)
Item 2 lists any special powers granted to the guardian of the person beyond the default. Defaults include custody, education, and ordinary medical care. Special powers may include psychotropic medication consent under Probate Code section 2356.5 or out-of-state travel.
The consequence of leaving a needed special power off is that doctors will refuse to prescribe. California’s Welfare and Institutions Code section 369.5 bars psychotropic medication without specific authorization.
A common misconception is that “medical care” includes psychotropic drugs. It does not. Antidepressants, ADHD stimulants, and antipsychotics each require a separate court order.
Item 3: Special Powers (Estate)
Item 3 lists special powers over the estate, such as authority to sell real property under Probate Code section 2540, to operate a business under Probate Code section 2476, or to invest beyond the statutory list.
The consequence of acting outside listed powers is surcharge: personal liability for any loss. The court may also remove the guardian under Probate Code section 2650.
A common misconception is that the guardian can use estate funds for the ward’s daily support without court approval. The guardian cannot. Probate Code section 2422 requires a court order before using estate funds for support.
Item 4: Other Powers and Restrictions
Item 4 lets the court add custom language, such as “Guardian shall not move ward outside California without further order” or “All funds shall be held in a blocked account at Bank of America, Walnut Creek branch.” Match the wording to the GC-240 order verbatim.
The consequence of mismatched wording is that the clerk may refuse issuance. The Letters cannot expand the order. They can only restate it.
A common misconception is that the guardian can later “amend” GC-140 by interlineation. The guardian cannot. Any change requires a new noticed motion under Probate Code section 2403.
Affirmation Block (Reverse Side)
The reverse side contains the Form GC-150 Duties of Guardian Acknowledgment signature line, although many counties use a separate GC-248. The guardian signs under penalty of perjury affirming receipt of the Duties pamphlet.
The consequence of skipping the affirmation is that no Letters issue. Probate Code section 2311(b) makes the affirmation jurisdictional.
A common misconception is that the affirmation is a formality. It is not. Signing it triggers fiduciary duty, and a knowing violation can be perjury under Penal Code section 118.
Clerk’s Certification and Seal
The clerk completes the bottom block, signs, dates, and embosses the seal. Do not fill in this block. Letters without the embossed seal are not valid for SSA, banks, or DMV purposes per SSA POMS GN 00502.139.
The consequence of accepting unsealed Letters is third-party rejection. Always request certified copies for $25 each in most counties under Government Code section 70626.
A common misconception is that a photocopy works. Most institutions, including California DMV for minor driver permits, demand a certified copy issued within the last 60 days.
Three Real-World Scenarios
Each scenario uses a different GC-140 configuration. The tables show the guardian’s choice and what follows.
Scenario 1: Grandparent Guardian of Person Only
| Decision Made on GC-140 | Resulting Authority or Limit |
|---|---|
| Box checked: Guardian of the Person | Grandparent can enroll ward in school under Education Code section 48204 |
| Item 2 lists psychotropic consent | Pediatrician may prescribe ADHD stimulants |
| Item 3 left blank | No authority to touch a $20,000 inheritance; blocked account stays frozen |
| No bond required | Bond waived because no estate is administered |
Scenario 2: Estate-Only Guardian for Inheritance Proceeds
| Decision Made on GC-140 | Resulting Authority or Limit |
|---|---|
| Box checked: Guardian of the Estate | Guardian can open blocked account at an FDIC-insured bank |
| Item 3 includes sale of real property | Guardian may sell inherited home with Probate Code section 2540 confirmation |
| Bond posted at $250,000 | Surety company protects ward against loss |
| Item 4 restricts withdrawals to court order | Each disbursement needs Form GC-400/GC-405 accounting |
Scenario 3: Combined Guardian of Person and Estate
| Decision Made on GC-140 | Resulting Authority or Limit |
|---|---|
| Both boxes checked | Single Letters cover custody and finances |
| Item 2 includes out-of-state travel | Guardian may relocate ward with court approval |
| Item 3 lists business operation | Guardian can run ward’s inherited LLC |
| Bond at $500,000 plus blocked account | Dual safeguard against fiduciary loss |
Named Examples Across the State
Elena Vasquez in Riverside files GC-140 as guardian of the person of her 7-year-old nephew after his parents are incarcerated. She checks only the Person box and lists no special powers. Three months later, when the school requests an IEP signature, her authority is clear under Education Code section 56028.5.
Marcus Johnson in Oakland is appointed guardian of the estate for his 12-year-old daughter after she receives a $300,000 wrongful-death settlement. His GC-140 lists a $330,000 bond and requires a blocked account at Chase. He cannot withdraw a dime without an order under Probate Code section 2422.
Sarah O’Connor in Sonoma is appointed guardian of both person and estate of her 4-year-old half-brother after their mother’s death. Her GC-140 includes special travel powers because the boy’s father lives in Oregon and ICWA-030 notice has cleared. She uses the Letters at SSA to redirect survivor benefits under 20 C.F.R. § 404.2010.
Mistakes to Avoid
Each error below has a specific bad outcome. Avoid all of them.
- Filing GC-140 before the judge signs GC-240, which causes the clerk to reject the Letters and triggers a refile fee under Government Code section 70617
- Checking Estate without posting bond, which freezes issuance under Probate Code section 2320 and delays access to ward’s funds
- Listing the minor’s nickname instead of legal name, which causes SSA Customer Identification rejection at the field office
- Forgetting to sign the Duties of Guardian acknowledgment on Form GC-248, which makes the Letters jurisdictionally void
- Using GC-140 for a temporary appointment instead of GC-150, which voids authority and exposes the guardian to liability
- Skipping psychotropic medication language in Item 2, which forces a separate motion under Probate Code section 2356.5 before any prescription
- Failing to order certified copies, which leaves the guardian unable to satisfy the DMV minor permit rule or open a blocked account
- Using a county’s wrong probate branch, which the LASC probate division and other hubs reject at the window
- Ignoring ICWA inquiry duties, which can void the appointment under In re Isaiah W. (2016) 1 Cal.5th 1
- Misstating the bond amount, which delays issuance until amended under Probate Code section 2322
Dos and Don’ts
The list below mirrors the Judicial Council’s self-help guardianship guide.
- Do type the form using the fillable PDF, because handwritten Letters are routinely rejected by clerks for legibility
- Do match every word of Item 4 to the GC-240 order, because mismatched wording forces a continuance and a new clerk review
- Do order at least three certified copies, because banks, schools, and SSA each demand their own original under Government Code section 70626
- Do file the GC-248 acknowledgment the same day, because Letters cannot issue without it under Probate Code section 2311
-
Do calendar the annual review, because the court schedules a status hearing one year out under California Rules of Court, rule 7.1005
-
Don’t sign the clerk’s certification block, because only the clerk’s signature and seal validate the Letters
- Don’t alter Letters with handwritten edits, because edited Letters are void and may constitute fraud under Penal Code section 115
- Don’t delay bond posting, because the clerk will not issue Letters until proof is filed under Probate Code section 2320
- Don’t ignore ICWA inquiry, because tribal notice failures void appointments retroactively
- Don’t use stale Letters, because most institutions refuse Letters more than 60 days old per SSA POMS GN 00502.139
Pros and Cons of Probate Guardianship via GC-140
The list draws from the California Courts self-help center.
- Pro: Court oversight protects the ward’s funds through bond and accounting under Probate Code section 2620
- Pro: Letters give the guardian instant credibility with schools, hospitals, and SSA, ending consent disputes
- Pro: The guardian gains standing to pursue the ward’s claims under Code of Civil Procedure section 372
- Pro: The arrangement is reversible by the parents through a Probate Code section 1601 petition when fitness returns
-
Pro: CalWORKs Approved Relative Caregiver funding becomes available for relative guardians
-
Con: Annual accounting under Probate Code section 2620 demands receipts, bank statements, and form work
- Con: Bond premiums cost roughly 0.5% of the bond amount per year, draining estate funds
- Con: The guardian needs court approval for major decisions like real estate sales under Probate Code section 2540
- Con: The court can remove the guardian on petition under Probate Code section 2650 for misconduct
- Con: The process requires Live Scan fingerprinting, investigator interviews, and ongoing reports
Key Entities You Will Encounter
The Judicial Council of California writes the form. The superior court probate department hears the case. The court investigator under Probate Code section 1513 interviews the proposed guardian, the parents, and sometimes the minor. The clerk issues the Letters.
The surety company posts bond. Top California sureties include The Hartford and SuretyBonds.com. Their underwriting depends on the guardian’s credit.
The Department of Social Services matters when the minor is also a California Dependency Court child. ICWA tribes participate when the minor may be Indian under 25 U.S.C. § 1903.
Bond, Blocked Accounts, and Court Investigators
Bond is governed by Probate Code section 2320. The amount equals the value of personal property plus one year’s income, plus a cushion for cost of recovery. The court can waive bond if the guardian uses a blocked account under Probate Code section 2328.
Blocked accounts under Probate Code section 2456 freeze funds until the ward turns 18 or the court orders release. Banks accept blocked accounts only with the MC-358 Order to Deposit form and certified GC-140 Letters.
The court investigator interviews under Probate Code section 1513. The investigator’s report can recommend denial. The judge usually follows the report.
A common misconception is that bond is optional in family cases. It is not, unless the court waives it. Estate of Bonaccorsi (1999) 69 Cal.App.4th 462 confirms that improperly waived bond can void later actions.
For example, Robert Kim of Ventura serves as estate guardian for his nephew. The court sets a $100,000 bond. Robert pays $500 in annual premium to a surety. When his nephew turns 18, the bond is exonerated under Probate Code section 2334.
Court Rulings That Shape GC-140 Practice
Guardianship of Ann S. (2009) 45 Cal.4th 1110 held that a probate guardianship can free a child for adoption when parents are absent, and the Letters provide the standing to file. In re Charlotte D. (2009) 45 Cal.4th 1140 applied the same rule to ICWA children.
Guardianship of L.V. (2006) 136 Cal.App.4th 481 limited a guardian’s reach over a parent’s reunification rights. The Letters do not erase parental rights; they suspend them under Family Code section 7505.
Guardianship of Christian G. (2011) 195 Cal.App.4th 581 required clear-and-convincing evidence to deny a fit parent’s request to terminate guardianship. Letters do not give permanent custody.
Frequently Asked Questions
Is California Form GC-140 the same as a court order?
No. GC-140 is the Letters proving authority, while Form GC-240 is the order making the appointment, and you need both to act for the minor.
Do I need a bond before GC-140 issues for an estate guardianship?
Yes. The clerk cannot issue estate Letters until the bond is filed under Probate Code section 2320, unless waived through a blocked account.
Can a non-relative serve as guardian using GC-140?
Yes. Any adult of suitable character may serve, but Probate Code section 1514 gives nominees by parents and close relatives statutory preference.
Does GC-140 expire?
No. Letters do not expire, but most third parties demand a certified copy issued within the past 60 days, so order new certified copies often.
Can I use GC-140 in another state?
Yes. Under the Uniform Child Custody Jurisdiction and Enforcement Act, other states honor California Letters, though some banks ask for ancillary orders.
Is GC-140 used for emergency guardianships?
No. Emergencies use Form GC-150 Letters of Temporary Guardianship under Probate Code section 2250, which last 30 days unless extended.
Can the guardian sell the minor’s house using only GC-140?
No. The guardian needs a separate confirmation order under Probate Code section 2540, even when GC-140 lists special sale powers.
Do I file GC-140 with the petition?
No. You prepare GC-140 in advance, but the clerk does not issue it until the judge signs GC-240 and you file the GC-248 acknowledgment.
Can a guardian be removed after GC-140 issues?
Yes. Any interested person may petition for removal under Probate Code section 2650 for misconduct, incapacity, or failure to perform duties.
Is fingerprinting required before GC-140 issues?
Yes. Most counties, including Sacramento Superior Court, require Live Scan under Probate Code section 1516.5 before Letters issue.
