Losing a partner to someone else’s negligence is devastating under any circumstances, but for unmarried couples, the legal path to compensation is far less clear than it is for married spouses. California does extend wrongful death rights to domestic partners, but the qualifications are specific, the documentation requirements are real, and the window to act is limited. Knowing where you stand legally from the start makes a critical difference in whether you are able to pursue a claim at all.
At Setareh Law, we help surviving family members throughout California navigate wrongful death claims, including those involving non-traditional family structures. With over $250 million recovered and 60 years of combined experience, our attorneys work to make sure every eligible party receives the full compensation the law allows.
Who Qualifies as a Domestic Partner Under California Law
California Code of Civil Procedure Section 377.60 governs who may bring a wrongful death lawsuit. It explicitly includes a decedent’s surviving domestic partner alongside spouses, children, and other heirs. However, the law draws a clear line between a registered domestic partner and an informal partner who simply lived with the decedent.
For purposes of wrongful death eligibility, California defines “domestic partner” as someone who was in a registered domestic partnership established in accordance with Section 297 of the Family Code at the time of the decedent’s death. This means the couple must have formally filed a Declaration of Domestic Partnership with the California Secretary of State. Simply cohabiting, sharing finances, or being in a long-term committed relationship is not enough on its own to qualify.
What Registered Domestic Partners Can Recover
Registered domestic partners who qualify as claimants under California law stand on essentially the same legal footing as a surviving spouse. They may recover a broad range of damages, and understanding what constitutes a wrongful death claim in California helps clarify the full picture of what losses the law recognizes.
Recoverable damages typically include financial support the surviving partner would have received, the reasonable value of household services the decedent provided, loss of the decedent’s companionship, comfort, and affection, and funeral and burial expenses. The strength of the claim depends heavily on the financial and personal interdependence of the couple, as courts evaluate how deeply the surviving partner’s life and economic stability were connected to the deceased.
The Challenge for Couples Without a Registered Partnership
According to a 2025 Pew Research Center analysis, approximately 7% of U.S. adults are cohabiting with an unmarried partner. Many of these couples share lives, finances, and households for years without formalizing their relationship through registration or marriage. For these partners, the path to a wrongful death claim is significantly more difficult.
An unregistered partner is not automatically entitled to bring a wrongful death claim. In some circumstances, a surviving partner may still be eligible if they can demonstrate financial dependency on the decedent and meet specific requirements under California law. This is a narrow exception, and proving it requires substantial documentation. Learning who can receive compensation from a wrongful death claim in California helps unregistered partners assess whether any path to recovery exists in their specific situation.
What Documentation Strengthens a Domestic Partner Claim
Whether a couple was registered or must argue for eligibility on another basis, documentation is the foundation of the claim. Relevant evidence may include a range of materials that establish the nature and depth of the relationship.
Joint bank account records, shared lease or mortgage agreements, insurance policies naming the surviving partner as a beneficiary, tax filings showing shared household, and communications demonstrating the couple’s mutual commitment can all support the claim. The long-term financial implications of a wrongful death claim extend well beyond immediate expenses, which is why building a complete evidentiary picture from the beginning of the process matters so much.
