Affidavit of Death of Joint Tenant: Definition and How It Works in California

By Eric Ridley, attorney, Ridley Law. Updated September 2026.

An affidavit of death of joint tenant is a sworn form a surviving owner records with the county, along with a certified copy of the death certificate, to show that a deceased joint tenant’s interest in real property has ended.

How it works in California

For the mechanics of preparing and recording this specific form, see affidavit of death of joint tenant in California. Prob. Code, §§ 210-212 set out what the affidavit has to contain: a description of the property, an affidavit from someone with knowledge of the facts, and an attested or certified copy of the death record.

Recording the affidavit is how a title company and the county recorder’s records come to reflect that the surviving joint tenant now owns the property outright. California law doesn’t require that it be recorded by any particular deadline, or at all; a joint tenant’s interest passes automatically at death by operation of law, and the affidavit is the standard way to make that transfer visible in the public record so the property can later be sold, refinanced, or transferred without a title problem.

Why it matters

For example, a surviving spouse who owned a house in joint tenancy with her late husband can keep living in it and paying the mortgage without recording anything. The gap shows up later, when she tries to sell or refinance and the title company won’t insure the property until the record shows how her husband’s interest ended.

Common mistakes

Waiting years to record the affidavit and then struggling to locate a certified death certificate or the exact legal description from the original deed. Assuming the affidavit itself transfers the property, when the transfer already happened at death and the affidavit only documents it. Recording the wrong form, such as an affidavit of death of trustee, when the property was actually held in joint tenancy rather than in a trust.
