How to Fill Out California Form AT-160 (w/Examples) + FAQs

Yes, you can complete California Form AT-160 yourself in under an hour if you gather the bill of sale, registration documents, and proof of any exemption before you start. Form AT-160 is the Affidavit for Transfer Without Probate used to claim a California-registered vehicle, vessel, or mobile home from a deceased owner whose total estate is small enough to skip full probate court.

The form looks short, but a single wrong checkbox or missing signature can stall the title transfer at the California DMV for months. According to the Judicial Council of California, more than 65% of small-estate transfers under $184,500 are now handled with affidavit-based forms like AT-160 instead of formal probate, saving heirs an average of $7,500 in court costs.

What Form AT-160 Really Is

California Form AT-160, officially titled the Affidavit for Transfer Without Probate California Titled Vehicle or Vessels Only, is a sworn statement filed with the California Department of Motor Vehicles to move title of a vehicle, vessel, or specific mobile homes from a deceased registered owner to the legal heir. The form is governed by California Probate Code §§ 13100–13116, which together create the “small estate” pathway.

The plain-English meaning is simple: if the person who died owned a car, boat, or covered mobile home in California, and the total value of everything they owned (minus a few exempt items) is under the statutory threshold, you do not need a judge to transfer the title. You sign AT-160, attach a death certificate, hand it to the DMV, and the title moves to you.

The consequence of skipping or botching this form is steep. Without a properly filed AT-160, the DMV will refuse to release title, the vehicle cannot be legally sold or insured in the new owner’s name, and unpaid registration fees keep stacking up. In a 2024 CDTFA enforcement bulletin, the agency reminded heirs that operating an unregistered inherited vehicle can trigger both DMV penalties and use tax assessments.

A real-world example helps. Maria, a daughter in Fresno, inherited her father’s 2018 Toyota Camry. Because his entire estate was worth $90,000, she filed AT-160, waited the required 40 days, and walked out of the DMV with new title in her name for under $25.

A common misconception is that AT-160 also transfers real estate, bank accounts, or stocks. It does not. Real estate uses Form DE-305, and most bank accounts use a separate small-estate affidavit under Probate Code § 13100.

Who Can Use Form AT-160

The form is available to a “successor of the decedent” as defined in Probate Code § 13006. That term covers the sole beneficiary under the decedent’s will, all beneficiaries acting together, or, if there is no will, the heirs entitled to the property under California’s intestate succession rules in Probate Code §§ 6400–6414.

The consequence of filing as the wrong person is automatic rejection plus possible perjury exposure, because AT-160 is signed under penalty of perjury. Jamal, a nephew in Oakland, learned this when he filed AT-160 for his late uncle’s truck without listing his two cousins, who were equal heirs; the DMV pulled the transfer and demanded a corrected affidavit signed by all three.

A misconception persists that the named executor in the will may sign alone. Not true. Until letters testamentary issue from a probate court, the will alone gives no signing power, and only the actual successors may use the small-estate affidavit pathway.

When AT-160 Becomes Available

Under Probate Code § 13100, the affidavit may be presented only after 40 days have passed since the date of death. The waiting period gives creditors and other heirs time to surface before assets are released.

Filing before day 41 leads to outright DMV rejection and forces you to refile, lengthening the wait. Linda, a widow in San Diego, mailed her AT-160 on day 35; the DMV returned it stamped “premature,” and she lost three weeks because she had to wait, recopy the death certificate, and resend.

The misconception that “40 days” means business days is wrong. The statute counts calendar days, weekends and holidays included.

When You Must Use AT-160 Versus Other Paths

Form AT-160 is the right tool only when three conditions all line up: a California-titled vehicle, vessel, or covered mobile home is involved; the gross value of the decedent’s entire California estate (with carve-outs) is at or below the cap; and 40 days have passed. Miss any one of these, and you must use a different process.

The current cap, set by Probate Code § 13100 and adjusted every three years under § 890, is $184,500 for deaths on or after April 1, 2022, and $208,850 for deaths on or after April 1, 2025. Always check the date of death against the cap in force on that day.

The consequence of forcing AT-160 onto an estate that exceeds the cap is severe. The DMV may transfer title in error, and creditors or omitted heirs can sue you personally under Probate Code § 13109 for the value received, plus attorney fees. Robert, a son in Sacramento, used AT-160 for his mother’s classic Mustang while quietly ignoring her $300,000 brokerage account, and a creditor of the estate later collected the full Mustang value from him personally.

The misconception that real property of any value can ride along with AT-160 is dangerous. Real property has its own forms and its own, smaller cap of $61,500 (gross) under Probate Code § 13200 for the affidavit procedure.

Spousal Property Alternative

A surviving spouse or registered domestic partner often has a faster route called the Spousal Property Petition, filed on Form DE-221. This route has no dollar cap and can transfer community property the day of death.

Choosing AT-160 instead of the spousal petition is fine for low-value vehicles, but not for boats or planes worth tens of thousands. The consequence of using AT-160 when a spousal petition would apply is usually only lost time and a slightly higher use tax exposure, but it can also waive certain community property protections.

A common myth is that surviving spouses must use the spousal petition. They may, not must, choose it.

Full Probate Versus AT-160

If the estate is over the cap, contested, or includes complicated assets, full probate under Probate Code § 7000 is required, and the personal representative will transfer the vehicle using letters of administration rather than AT-160.

The consequence of mixing the two paths is title clouding. Title insurance and lenders may refuse to recognize a buyer down the road if the chain shows an AT-160 transfer that should have been a probate sale.

The misconception that probate “always” takes years is overstated. California’s Heggstad and summary procedures often close in 6 to 9 months when there is no dispute.

Step-by-Step: Filling Out Form AT-160 Line by Line

Form AT-160 is a one-page document with eight numbered sections, plus the signature block. Below is the line-by-line breakdown using the current revision posted on the DMV forms portal.

Read each line twice before writing. The form is signed under penalty of perjury under Probate Code § 13101, and a wrong answer is not a typo, it is a sworn lie.

The DMV reviewer is trained to spot mismatches between the affidavit and the title record. Any inconsistency, even a middle-initial swap, can trigger a hold and a request for a corrected form.

Section 1: Decedent Information

Line 1 asks for the full legal name of the deceased exactly as it appears on the California Certificate of Title or current registration. If the title says “ROBERT J. SMITH” and the death certificate says “Robert James Smith,” write “Robert James Smith (aka Robert J. Smith)” so the names reconcile.

Line 2 asks for the date of death. Use the date on the certified death certificate from the California Department of Public Health, not a funeral home printout. The consequence of using a non-certified date is rejection.

Line 3 asks for the county of death. Match the county printed on the death certificate, even if the decedent lived elsewhere; the DMV cross-checks vital records.

Section 2: Vehicle or Vessel Description

Line 4 demands the VIN or HIN (vehicle identification number for cars, hull identification number for boats), license plate or CF number (the California vessel number), year, make, and body type. Pull these directly from the title or current registration card to avoid transposed digits.

The consequence of any mismatch is automatic kickback. Priya, an heir in San Jose, swapped a “B” for an “8” in her late mother’s VIN and waited five extra weeks for a corrected affidavit to clear.

A common myth is that a partial VIN suffices. The DMV requires the full 17-character VIN for any 1981-or-newer vehicle, per 49 CFR § 565.

Section 3: Statement of Value

Section 3 is a sworn statement that the gross value of the decedent’s entire California estate, excluding the assets carved out by Probate Code § 13050, does not exceed the statutory cap.

The carve-outs include joint tenancy property, payable-on-death accounts, life insurance, retirement accounts with named beneficiaries, registered vehicles up to $20,000 (in some prior calculations), and salary owed up to $19,573. Subtract these before testing the cap.

The consequence of overstating the carve-outs is personal liability under Probate Code § 13109.5. David, a brother in Long Beach, ignored his sister’s $250,000 IRA’s contingent-beneficiary issue and signed AT-160 anyway; the IRS and the contingent beneficiary both came after him.

A persistent misconception is that out-of-state assets count toward the California cap. They do not, but they may trigger probate in the other state.

Section 4: Successor Declaration

Section 4 is where you, the signer, declare your status as the successor. You must check either box A (“sole successor”) or box B (“all successors are signing this affidavit, and their names appear below”).

The consequence of checking box A when other heirs exist is fraud exposure. The consequence of checking box B without all signatures is rejection.

A common myth is that a notarized signature from one heir can stand in for another. It cannot, unless that heir granted a specific power of attorney before death, attached to the form.

Section 5: No Pending Probate

Line 5 swears that no probate proceeding is pending or has been conducted for the decedent’s estate in California. The DMV cross-checks the California Courts case search for probate filings.

The consequence of a false statement here is automatic rejection plus a perjury referral. Susan, a daughter in Riverside, filed AT-160 while her brother had quietly opened probate in Los Angeles County; the DMV caught it and referred the file to the district attorney.

The misconception that a closed probate blocks AT-160 is wrong. Only a pending probate blocks the form; a closed probate that did not include the vehicle leaves the affidavit pathway open.

Section 6: Right to Property

Line 6 states that you, as successor, are entitled to the described vehicle or vessel. If the will leaves the vehicle to a specific person, that person is the only one who may claim it.

The consequence of claiming a vehicle willed to someone else is a creditor-style lawsuit by the rightful beneficiary. A common misconception is that “all heirs share everything equally” overrides a specific bequest. It does not; a specific bequest controls.

Section 7: Lien and Loan Disclosure

Line 7 asks whether the vehicle has any outstanding lien. If yes, the lienholder’s payoff letter must accompany the affidavit, and the lien releases only after payoff or assumption.

The consequence of omitting a known lien is title fraud. Carlos, a son in San Bernardino, hid his father’s $8,000 RV loan; the lender repossessed the RV three months later, and Carlos lost both the vehicle and the use tax he had paid.

A myth says inherited debts vanish at death. They do not; secured debts ride with the asset.

Section 8: Signature Block

The signer prints name, signs, dates, and provides a daytime phone. A notary acknowledgment is required in every California county per the DMV’s 2023 revision, even though the underlying statute only requires notarization in some scenarios.

The consequence of skipping notarization is rejection. The misconception that an “acknowledgment by a DMV clerk” replaces a notary is wrong; the DMV stopped offering that service in 2018.

Three Real-World Filing Scenarios

Scenarios make the rules click. Each table below shows a typical fact pattern and the practical outcome at the DMV counter.

The first scenario is the cleanest, and most filers will land here. The second adds a sibling dispute. The third adds a lien.

Scenario A: Solo Heir, Free-and-Clear Car

Filer Step	DMV Outcome
Maria waits 41 days after father’s death	Affidavit timing valid
Lists $90,000 total estate, well under cap	Section 3 passes
Checks box A, sole successor	Section 4 passes
Notarizes signature, attaches death certificate	Title transfers in 10 business days

Scenario B: Two Siblings, One Car

Filer Step	DMV Outcome
Jamal and his sister both sign AT-160	Section 4 box B satisfied
Both attach photo ID	DMV verifies signatures
Estate value $150,000, no real property	Section 3 passes
One sibling later wants the car alone, files quitclaim from the other	DMV transfers to the keeping sibling

Scenario C: Lienholder Involved

Filer Step	DMV Outcome
Carlos discloses $8,000 RV loan in section 7	Section 7 passes
Attaches payoff letter from credit union	Lien-release path opens
Pays off loan from estate cash	Lender issues lien release
Submits release with AT-160	Title transfers free of lien

Named Examples to Anchor the Rules

Aisha, a 34-year-old marketing manager in Long Beach, inherited her mother’s 2020 Honda Civic worth $18,000. Because the entire estate was $120,000 with no debts, she filed AT-160 on day 42, attached a certified death certificate, and walked out of the Long Beach DMV field office with new title in 14 days.

Tomás, a 58-year-old contractor in Bakersfield, inherited a 28-foot fishing vessel from his uncle. The boat’s CF number had lapsed; Tomás first paid the back registration on DMV Form REG 343, then filed AT-160. The CDTFA later assessed use tax under Pub 79A, which Tomás paid using the boat’s Kelley Blue Book value as his measure.

Hannah, a 27-year-old teacher in Stockton, was named in her grandmother’s handwritten will to receive a 1972 Volkswagen bus. The estate totaled $200,000, just under the 2025 cap. Hannah filed AT-160, but the DMV requested the will because her last name differed from the registered owner’s; once she attached a copy of the holographic will, title transferred.

Mistakes to Avoid

Each error below has stalled real filings. Avoiding them keeps your transfer on the 10-to-14-day track instead of the 6-to-12-week track.

Filing before the 40-day waiting period closes, which causes automatic rejection under Probate Code § 13100
Forgetting to attach a certified (raised-seal) death certificate, since the DMV refuses photocopies
Missing one heir’s signature when more than one successor exists, voiding the entire affidavit
Underreporting estate value to slip under the cap, which exposes you to personal liability under § 13109
Skipping notarization, which the DMV’s 2023 revision now treats as a fatal defect
Ignoring a lien in section 7, which leads to repossession and lost equity
Using the wrong cap amount for the date of death, which voids the sworn statement

Use Tax, Fees, and Penalties

Most heirs do not owe use tax on a vehicle inherited through AT-160 because the CDTFA family-transfer exemption covers transfers from a deceased parent, child, spouse, sibling, or grandparent to certain relatives. The exemption is claimed on CDTFA-111 at the DMV.

The consequence of failing to claim the exemption is paying tax you did not owe, often 7.25% to 10.25% of fair market value. The misconception that “inheritance is always tax-free” ignores the non-relative successor scenario; a friend named in a will pays full use tax.

Standard DMV transfer fees include the $15 transfer fee, a $23 California Highway Patrol fee in some counties, plus any back registration. The DMV fee calculator shows the full amount before you visit.

Late Penalties

Registration penalties accrue from the date of death if the vehicle expires during the transfer window. The penalty schedule from Vehicle Code § 9554 starts at 10% and climbs to 60% after one year.

The consequence of waiting beyond the registration expiration is steep. Tomás’s boat above accrued $340 in penalties before he caught up. The misconception that “death pauses registration” is false; registration runs with the vehicle, not the owner.

Smog and Inspection

A smog certificate is required on most title transfers, but Health and Safety Code § 44011 exempts transfers between family members and certain inherited transfers. Confirm exemption before paying for a smog test.

The consequence of missing the smog when required is rejection of the entire AT-160 packet. The myth that all inherited cars are smog-exempt is wrong; non-family heirs usually still need the smog.

Do’s and Don’ts

Each rule below has a one-line “why” so you can see the logic.

Do wait the full 40 calendar days, because earlier filings violate § 13100 and get bounced
Do attach a certified death certificate, because the DMV cross-checks the seal against state vital records
Do list every successor on box B, because omitted heirs can sue you for their share
Do disclose every lien, because hiding one is title fraud and a felony under Vehicle Code § 4463
Do keep a copy of the signed AT-160 for seven years, because the CDTFA audit window stretches that far for use tax
Don’t guess the VIN, because one wrong digit voids the affidavit
Don’t overstate carve-outs in section 3, because the DMV and IRS share data
Don’t sign for a co-heir, because forgery is a separate felony
Don’t skip the notary, because the 2023 form revision now requires it in every county
Don’t ignore CDTFA-111, because losing the family exemption is the most common avoidable cost

Pros and Cons of the AT-160 Path

Each item below carries a short reason so you can weigh it against probate or the spousal petition.

Pro: Cheap, because total filing cost is under $50 versus $7,500 average probate
Pro: Fast, because the DMV typically issues new title in 10 to 14 business days
Pro: Private, because no court file is created
Pro: Self-service, because no attorney is required by statute
Pro: Flexible, because vessels, vehicles, and some mobile homes all use the same form
Con: Personal liability, because signers are responsible to creditors under § 13109
Con: Cap-limited, because estates over $184,500 (or $208,850 post-April 2025) cannot use it
Con: Dispute-fragile, because any sibling can block the transfer by refusing to sign
Con: No court oversight, because mistakes surface later as title clouds
Con: Use tax exposure, because non-family heirs still owe full tax

Key Entities Involved

The California DMV processes the affidavit and issues new title. The California Department of Public Health issues the certified death certificate that anchors the filing.

The California Department of Tax and Fee Administration governs use tax on vessels and aircraft and reviews CDTFA-111 exemption claims. The Judicial Council of California sets the underlying small-estate forms and updates dollar thresholds every three years.

The successor of the decedent, the lienholder, and the notary public round out the cast. Each plays a distinct role: the successor signs, the lienholder releases security, and the notary certifies identity.

Court Rulings That Shape AT-160

In Estate of Bonanno (2008) 165 Cal.App.4th 7, the court of appeal confirmed that a successor who signs a small-estate affidavit “stands in the shoes” of the decedent for creditor claims, locking in personal liability up to the value received.

In Estate of Heggstad (1993) 16 Cal.App.4th 943, the court paved the way for non-probate transfers of trust property, indirectly reinforcing the affidavit pathway for non-trust vehicles.

In Parson v. Tickner (1995) 31 Cal.App.4th 1513, the court held that a successor who failed to disclose other heirs was personally liable for their share plus attorney fees, a holding that still drives the strict box-B signature rule today.

FAQs

Can I file Form AT-160 before 40 days have passed since the death?

No. Probate Code § 13100 requires a full 40 calendar days, weekends and holidays included, before any successor may present the affidavit to the DMV.

Does Form AT-160 transfer real estate or bank accounts?

No. AT-160 covers only California-titled vehicles, vessels, and certain mobile homes; real estate uses Form DE-305, and bank accounts use a separate § 13100 affidavit.

Do I owe use tax on a vehicle inherited through AT-160?

No, in most family transfers, because the CDTFA family exemption applies; non-family successors, however, owe full use tax based on the vehicle’s fair market value.

Must every heir sign Form AT-160?

Yes. When more than one successor exists, each must sign in the box B section, or the DMV will reject the affidavit and require a refiled, fully signed version.

Is notarization required on Form AT-160?

Yes. The 2023 DMV revision requires a notary acknowledgment in every California county, regardless of the underlying Probate Code requirements that once allowed exceptions.

Can I use AT-160 if probate is already open?

No. Section 5 of the affidavit swears that no probate is pending; filing while a probate case is open exposes you to perjury referral and automatic rejection.

Does AT-160 work for out-of-state vehicles?

No. The form is limited to California-titled vehicles and vessels; an out-of-state vehicle must first be registered in California or transferred under that state’s small-estate rules.

Can a power of attorney sign AT-160 for a deceased person?

No. All powers of attorney terminate at death under Probate Code § 4152; only a successor may sign the affidavit.

Is a smog certificate always required when filing AT-160?

No. Family-member transfers and many inherited transfers are exempt under Health and Safety Code § 44011, but non-family heirs usually must still provide one.

Can creditors of the decedent come after me after I file AT-160?

Yes. Under Probate Code § 13109, unpaid creditors of the decedent may collect from any successor up to the fair market value of property received through the affidavit.

Does the cap include life insurance proceeds?

No. Probate Code § 13050 excludes life insurance with a named beneficiary, joint tenancy property, and retirement accounts with beneficiaries from the small-estate cap calculation.

Can I sell the inherited vehicle before filing AT-160?

No. Without new title in your name, any sale is void; California Vehicle Code § 5600 requires a properly endorsed title for every transfer.
