Short answer: California treats married same-sex couples exactly the same as opposite-sex couples for wills, trusts, and default inheritance rights. Marriage does not finish the job, though. LGBTQ+ families still need the same core documents every California family needs, and a few gaps deserve extra attention: legal parentage for children raised without a biological or adoptive link to both partners, unmarried or domestic-partnered couples who do not get California’s default marital protections, and recognition outside California if you own property or spend time in another state.
Does marriage in California put same-sex couples on equal footing?
Yes. California recognizes same-sex marriage on the same terms as opposite-sex marriage, and the state’s community property and default inheritance rules apply without regard to the spouses’ sex or gender. That equal treatment covers who can make medical decisions for an incapacitated spouse, who inherits property when a spouse dies without a will, and who has standing to serve as executor or trustee.
Equal treatment under California law does not automatically travel with you everywhere. If you own property in another state, work for an employer based elsewhere, or spend significant time outside California, that state’s law, not California’s, may control certain parts of your plan. A written estate plan, rather than reliance on marital status alone, is what actually holds up wherever you go.
What if we are not married, or we are registered domestic partners instead?
Registered domestic partners have many of the same rights as married couples under California law, but the overlap is not perfect, particularly where federal law is involved. Unmarried partners, whatever the length or seriousness of the relationship, generally have no automatic inheritance rights at all. If one partner dies without a will or trust, California’s intestate succession rules control who inherits, and an unmarried partner is not in that line of succession.
For unmarried couples, a written estate plan is not optional in the way it might be for a married couple who can lean on default marital protections as a backstop. It is the only way to make sure your partner inherits anything, has authority to handle your affairs if you become incapacitated, and has standing to make medical decisions if you cannot make them yourself.
What documents do LGBTQ+ families in California actually need?
The document set is the same one every California family needs. What changes is how carefully it has to be drafted to say what your family actually means, rather than relying on assumptions a hospital, bank, or court might not share.
- A will. A will directs who receives your property and, for parents of minor children, who you want to serve as guardian. A will by itself does not avoid probate. It only takes effect once a court validates it through the probate process.
- A revocable living trust. A properly funded trust holds title to your assets during your lifetime and distributes them according to your instructions after death, generally without court involvement. A trust that is never funded, meaning assets are never retitled into it, does not avoid probate for whatever was left out.
- A durable power of attorney. This document names someone to handle your financial and legal affairs if you become unable to manage them yourself. Without one, the person you would choose, including a partner who is not a legal spouse, may have no authority to act on your behalf.
- An advance health care directive. This names your health care agent and states your treatment preferences if you cannot speak for yourself. For unmarried or non-biological family members, this document is often the only thing that gives your chosen person a seat at the table in a hospital setting.
How do we protect our children’s legal relationship to both parents?
A birth certificate, a marriage license, or being listed as a parent on school or medical paperwork does not automatically establish legal parentage in every situation, particularly in another state or in a dispute that reaches a court. For LGBTQ+ parents who used assisted reproduction, surrogacy, or a partner’s prior relationship to build their family, the safest way to lock in a legal parent-child relationship for a non-biological or non-gestational parent is typically a formal adoption or a court judgment of parentage, not paperwork alone.
This matters directly for estate planning. If a legal parent-child relationship is ever questioned, it can affect guardianship nominations, inheritance, and who has authority to make decisions for the children if something happens to one or both parents. Naming a guardian in your will is a strong first step, but it works best layered on top of a secure legal parentage foundation, not in place of one.
What about property or family outside California?
California’s protections for LGBTQ+ families are not universal law. If you own a vacation home in another state, if a partner’s family lives elsewhere and might contest your plan, or if you relocate later, a plan built only around California assumptions can leave gaps. A trust that holds out-of-state property, paired with documents drafted to anticipate a move, generally holds up better than relying on the fact that California currently recognizes your marriage or partnership.
What to do next
Start with the same four documents every California family needs: a will, a funded revocable living trust, a durable power of attorney, and an advance health care directive, then build in the specific protections your family needs around parentage, out-of-state property, or an unmarried partnership. An estate planning attorney can review your family’s actual structure, not just your marital status, and make sure the paperwork matches it.
