If you’re handling a loved one’s property in California after they’ve passed away without a will or trust, you might need to file an affidavit of heirship. It’s not a court process like probate but it’s still legally binding if done right. Getting the California legal requirements for filing an affidavit of heirship wrong can delay title transfers, cause disputes among heirs, or even lead to rejection by title companies or county recorders.

What is an affidavit of heirship in California?

An affidavit of heirship is a sworn statement signed in front of a notary that identifies who the legal heirs are and how property should pass after someone dies intestate (without a will). It’s most commonly used for real estate, especially when the deceased owned land or a home solely in their name and there’s no probate estate. Unlike probate, it doesn’t require a judge’s approval. But that doesn’t mean it’s informal: California law sets clear rules about who can sign it, what must be included, and how it must be filed.

Who can sign and file it?

Only certain people may sign an affidavit of heirship in California and only those with personal knowledge of the decedent’s family, marriage, and children. That usually means a relative, close friend, or neighbor who knew the person well for at least five years before death. The signer must be disinterested (not an heir themselves) or, if they are an heir, they must disclose that fact clearly. You’ll also need two witnesses who know the facts and sign under penalty of perjury.

It’s important to confirm eligibility early. For example, a distant cousin who never met the decedent or a paid caregiver with no firsthand knowledge of family relationships can’t legally sign. If you’re unsure whether someone qualifies, review the eligibility rules or consult a probate attorney.

What must the affidavit include?

California Probate Code § 210 provides the framework. A valid affidavit must state:

• The decedent’s full name, date and place of death, and last known address;
• Whether they were married, widowed, divorced, or single and details about any surviving spouse;
• A list of all known children (including adopted and stepchildren, if legally recognized), parents, and siblings;
• Whether the decedent had a will or trust and if so, why it doesn’t control this property;
• How the property is held (e.g., “as sole owner,” “community property,” or “joint tenancy”);
• A description of the property, including its legal description (not just the street address);
• A statement that the signer has personal knowledge of these facts and is not an heir or, if they are, that they’ve disclosed it.

You’ll also need to attach certified copies of the death certificate and any marriage or divorce documents that support heirship claims.

Where and how do you file it?

You don’t “file” the affidavit with a court. Instead, you record it with the county recorder’s office where the real property is located. Once recorded, it becomes part of the public chain of title. Some title companies accept affidavits of heirship for sales or refinancing but others require additional documentation or refuse them outright, especially for high-value properties or complicated family situations.

Before recording, make sure the document meets your county’s formatting rules like margin size, font, and notary wording. Los Angeles County, for instance, requires a $15 recording fee and a cover sheet with specific information. Always call ahead or check the county recorder’s website for current instructions.

Common mistakes people make

Leaving out a living heir even a half-sibling or adult child born outside marriage is the most frequent error. California presumes all children inherit equally unless proven otherwise, and omitting one can invalidate the entire affidavit later.

Another mistake is using vague language: “John was married once” instead of naming the spouse and stating whether the marriage ended in death or divorce. Or listing “two sons” without names, birthdates, or whether they’re alive or deceased.

Some people assume signing the affidavit gives them ownership. It doesn’t. It only supports a claim of heirship. To actually transfer title, you’ll usually need a quitclaim deed signed by all heirs or, in some cases, a court order.

When should you consider something else instead?

An affidavit of heirship works best for straightforward cases: one piece of real estate, clear family relationships, no contested heirs, and no debts tied to the property. If the decedent had significant debt, multiple properties, or unclear parentage (e.g., unknown fathers or unadopted stepchildren), probate or a petition to determine succession of estate may be safer and more reliable.

You might also need a different type of affidavit if the property is held in joint tenancy or if the heir is a minor.

Next step: Review and record

Before you record anything, double-check that:

1. The signer meets California’s personal knowledge and interest requirements;
2. All heirs including those who may have predeceased the decedent are named and accounted for;
3. The legal description matches the deed on file with the county;
4. The notary section follows California’s statutory wording (Probate Code § 210);
5. You’ve included certified copies of supporting documents.

If everything checks out, take the completed, notarized affidavit to your county recorder’s office or mail it with payment and a self-addressed stamped envelope if allowed. Keep a certified copy for your records. And if you’re unsure about any part of the process, talk with someone familiar with California’s rules for who can submit an affidavit of heirship.
