If you’re handling a loved one’s property in California without a will or probate, you might need to file an heirship affidavit. It’s not a court process it’s a sworn statement used to prove who inherits real or personal property when someone dies intestate (without a will). Getting it right matters because banks, title companies, and county recorders rely on this document to transfer ownership. A small error like missing a required witness signature or misidentifying heirs can delay access to assets for months, or worse, trigger legal challenges later.

What is an heirship affidavit in California?

An heirship affidavit is a legal form signed under penalty of perjury that identifies the deceased person’s heirs and explains how property should pass under California intestacy law. It’s commonly used for small estates especially for transferring real property like a house or land when probate isn’t required or has been avoided. Unlike a formal probate proceeding, it doesn’t involve a judge or court filing, but it must meet strict statutory requirements under California Probate Code § 13100.

When do you actually need to file one?

You’d use an heirship affidavit when: the deceased left no will; the estate qualifies as “small” (under $184,500 in 2024 for non-real property, or real property valued below certain thresholds); and the asset holder like a bank or county recorder accepts the affidavit instead of requiring probate. For example, if your parent died owning a paid-off mobile home in Riverside County and left only you and a sibling as heirs, the park manager may ask for an heirship affidavit before letting you take over the lease or sell the unit.

Who can sign it and who can’t?

At least two disinterested witnesses must sign the affidavit people who knew the deceased, are over 18, and aren’t heirs themselves or related by blood or marriage to anyone claiming inheritance. The heirs named in the affidavit cannot serve as witnesses. Also, the person signing the affidavit (often one heir acting on behalf of others) must have personal knowledge of the family relationships and facts stated not just what they’ve heard from relatives. That’s why some people mistakenly list a cousin who “thinks” a distant relative is alive, only to find out later the person passed away years earlier. That kind of error can invalidate the whole document.

Where and how do you file it?

You don’t “file” it with a court but you do record it with the county recorder’s office where the real property is located, if it involves land or a home. For personal property (like a bank account), you submit the signed, notarized affidavit directly to the institution holding the asset. In both cases, it must be notarized and include specific details: full names and addresses of all heirs, dates of birth and death, relationship to the deceased, and a description of the property. Some counties like San Diego also require a preliminary change of ownership report (PCOR) alongside the affidavit. Skipping that step is one of the most common oversights we see.

What mistakes trip people up most often?

People forget to update heir information when someone has died since the original affidavit was drafted or they leave out a half-sibling who wasn’t in contact but is still a legal heir under California law. Others assume signing once covers all assets, but each institution may require its own version. And many don’t realize that if the deceased had debts, creditors can still come after the property even after an heirship affidavit is recorded. You’ll want to review the full list of common mistakes when submitting heirship affidavit in California to avoid those pitfalls.

Can you fix an error after it’s submitted?

Yes but not easily. If the affidavit hasn’t been accepted yet, you can withdraw and re-submit with corrections. Once it’s recorded or accepted by a bank, though, you’ll likely need to file a corrective affidavit or, in some cases, go through probate to clear title. That’s why double-checking heir names, dates, and signatures before notarization saves time and stress.

Next step: Get it reviewed before submission

Before you notarize or send anything, compare your draft against the official California Judicial Council form (Form DE-310) and verify every heir’s status using birth certificates, marriage licenses, or death certificates. If there’s any uncertainty like a missing heir, a prior divorce affecting inheritance rights, or property held in joint tenancy talk to a probate attorney. You can also walk through the correct steps for heirship affidavit submission in California to confirm timing, witnesses, and recording requirements for your county.

Quick checklist before signing:

  • All heirs are correctly identified including those born outside marriage or adopted
  • At least two disinterested witnesses signed (not heirs, not spouses of heirs)
  • The affidavit is notarized in California (out-of-state notarization won’t work)
  • Real property descriptions match county assessor records exactly
  • You’ve included a PCOR if filing with a county recorder
