Yes, gay marriage is legal in California, and has been continuously since June 2013. It is protected twice over: California voters wrote the right to marry into the state constitution by passing Proposition 3 in November 2024, and the U.S. Supreme Court’s 2015 decision in Obergefell v. Hodges guarantees the right nationwide.1Legislative Analyst’s Office. Proposition 3 Constitutional Right to Marriage Same-sex couples who marry in California receive identical legal rights to opposite-sex married couples, from property and taxes to parental rights and federal benefits.
What Rights You Get by Marrying in California
Marriage triggers a broad set of legal rights under both state and federal law. They apply the same way regardless of the sex of the spouses.
Property and Spousal Support
California is a community property state. Property acquired by either spouse during the marriage is generally owned equally by both, no matter who earned it or whose name is on the title.2California Legislative Information. California Code FAM 760 – Community Property In a divorce, community property is typically divided equally, while each spouse keeps their separate property, meaning assets owned before the marriage or received as a gift or inheritance.3Judicial Branch of California. Property and Debts in a Divorce Courts can also order spousal support, weighing factors such as each spouse’s earning capacity, the standard of living during the marriage, the length of the marriage, and the age and health of both spouses.4Justia. California Code FAM 4320-4326 – Factors to Be Considered in Ordering Support
Social Security and Survivor Benefits
The Social Security Administration recognizes same-sex marriages for all benefit purposes. When you claim retirement benefits, your spouse may qualify for benefits based on your earnings record, and if you die, your surviving spouse can receive survivor benefits.5Social Security Administration. What Same Sex Couples Need to Know The SSA has special rules for couples who would have married earlier if their state had allowed it: if you can show you would have been married at the time of your partner’s death but for unconstitutional state laws, you may still qualify for survivor benefits.
Immigration
U.S. Citizenship and Immigration Services treats same-sex marriages the same as opposite-sex marriages. A U.S. citizen or permanent resident can sponsor a same-sex spouse for a green card. USCIS applies a place-of-celebration rule, so a marriage performed in California is valid for federal immigration purposes regardless of where the couple later lives.6U.S. Citizenship and Immigration Services. Chapter 2 – Marriage and Marital Union for Naturalization
Taxes
Married same-sex couples file taxes the same way any married couple does. On federal returns, you use either married filing jointly or married filing separately. California follows the same approach at the state level, and married couples and registered domestic partners file as married/RDP filing jointly or married/RDP filing separately.7Franchise Tax Board. 2025 Personal Income Tax Booklet Marriage also unlocks the federal marital deduction for estate and gift tax purposes, letting a surviving spouse inherit an unlimited amount from their deceased spouse without federal estate tax; the per-person exemption is $15 million for 2026.8Internal Revenue Service.

Parentage
California applies a marital presumption of parentage. If you are married and your spouse gives birth during the marriage, you are presumed to be the child’s legal parent regardless of biological relationship.9California Legislative Information. California Family Code 7611 That presumption covers same-sex couples on the same terms.
Even so, family law attorneys widely recommend that non-biological parents in same-sex marriages obtain either a stepparent or second-parent adoption or a court parentage judgment, even when both parents are listed on the birth certificate. A birth certificate alone does not guarantee your parental rights will hold up if challenged in court or in another state. A court order is far harder to contest and provides an extra layer of protection when traveling, dealing with schools and medical providers, or moving to a less protective jurisdiction. For couples using assisted reproduction with a donor who is not the spouse, California’s Uniform Parentage Act allows both parents to establish legal parentage through a Voluntary Declaration of Parentage. Surrogacy arrangements are not covered by that process and require a separate court proceeding.
How to Get Married in California
The process is the same for same-sex and opposite-sex couples. Both partners must be at least 18, unmarried, and not closely related. Minors can marry only with both parental consent and a court order.
Apply for a marriage license at any county clerk’s office in California. Bring valid photo identification proving your name and date of birth: a driver’s license, passport, military ID, or resident alien card. Fees vary by county, generally falling between $60 and $110. Once issued, the license is valid for 90 days, and your ceremony must take place inside that window.10Justia. California Code FAM 350-360 – Marriage License
California doesn’t require any particular ceremony format, but both partners must declare in the physical presence of the officiant that they take each other as spouses. Authorized officiants include judges, religious leaders, and individuals ordained online.
If You Marry Here and Move Somewhere Else
A California marriage remains legally recognized if you move. The Respect for Marriage Act, signed into federal law in December 2022, requires every state to honor marriages that were valid where performed, regardless of the sex, race, or national origin of the spouses.11Office of the Law Revision Counsel. 28 U.S. Code 1738C – Certain Acts, Records, and Proceedings and the Effect Thereof California separately recognizes any marriage valid where it was performed, so marriages from other jurisdictions are honored here as well.12California Legislative Information. California Family Code 308
Domestic Partnership Is Not the Same as Marriage
California still offers registered domestic partnerships. Under state law, domestic partners have the same rights, responsibilities, and obligations as married spouses.13California Secretary of State. Frequently Asked Questions The federal side is where the gap opens. The federal government does not treat registered domestic partners as spouses for tax purposes, so domestic partners cannot file joint federal returns and can miss out on other federal benefits tied to marriage.
If you are already in a domestic partnership and want to marry the same partner, you don’t have to dissolve the partnership first. California lets both coexist between the same two people. Once you’re married, the marriage itself carries all the state and federal protections, and keeping the partnership alongside it adds nothing further. Registration for domestic partnerships is handled through the California Secretary of State, not a county office; a city or county registry doesn’t confer state-level rights.13California Secretary of State.

How the Right Became Settled Law
California’s route to marriage equality moved through the state courts, the ballot box, and the federal courts. In May 2008, the California Supreme Court ruled in In re Marriage Cases that state laws restricting marriage to opposite-sex couples violated the California Constitution.14California Supreme Court Resources Stanford Law School – Robert Crown Law Library. In re Marriage Cases – 43 Cal 4th 757 That November, voters passed Proposition 8, which added language to the state constitution defining marriage as between a man and a woman.15Secretary of State. Proposition 8 – Title and Summary – Voter Information Guide 2008 Federal courts struck down Proposition 8, the U.S. Supreme Court declined to disturb that ruling on June 26, 2013, and same-sex marriages resumed in California two days later.
In June 2015, the U.S. Supreme Court decided Obergefell v. Hodges, holding that the Fourteenth Amendment guarantees same-sex couples the right to marry in every state.16Justia U.S. Supreme Court Center. Obergefell v. Hodges, 576 U.S. 644 (2015) Congress added a federal statutory safeguard through the Respect for Marriage Act in December 2022. And in November 2024, California voters approved Proposition 3, which removed the obsolete Proposition 8 language from the state constitution and replaced it with an affirmative right to marry.1Legislative Analyst’s Office. Proposition 3 Constitutional Right to Marriage The measure didn’t change who can marry, but it made the constitution’s text match the law.
