In a California same-sex divorce or domestic partnership dissolution, the family home is divided under the same community property rules that apply to every married couple. A home bought during the marriage or partnership with earnings from that time is generally community property and split equally. A home owned beforehand, or bought with a gift or inheritance, is generally separate property. Community mortgage payments can still create a shared interest.
Most people facing this question are not looking at a simple timeline. The house may have been bought years before the two of you could marry. You may have registered as domestic partners, lived through the Proposition 8 years, and married later. The mortgage may have been paid from one person's savings at first, then from shared paychecks. So the real question is less "who gets the house" and more "which parts of this home's history count, and how."
This article walks through how California characterizes a family home, meaning how the law decides who owns which part of it. It also covers how the relationship history particular to many same-sex couples shapes that answer, and what options exist for the home when the relationship ends.
How California Community Property Law Applies to Same-Sex Couples
Family Code section 760 sets the starting rule: "all property, real or personal, wherever situated, acquired by a married person during the marriage while domiciled in this state is community property," except as otherwise provided by statute. Community property means assets that both spouses own together, in equal shares, simply because they were acquired during the marriage. Neither person has to be on the title, and neither has to have earned the money.
This rule applies to same-sex spouses exactly as it does to any married couple. Nothing in the community property statutes turns on the gender of the spouses.
Registered domestic partners stand in the same place. Under AB 205 (Stats. 2003, ch. 421), from January 1, 2005, registered domestic partners have the rights and duties of spouses, whenever they registered. Family Code section 299(d) reinforces this for the end of the relationship. Partners dissolving a domestic partnership "shall possess the same rights, protections, and benefits, and be subject to the same responsibilities, obligations, and duties" as spouses in a dissolution of marriage.
Two more rules shape how the home is treated. Under Family Code section 721, spouses owe each other "a duty of the highest good faith and fair dealing" in transactions between themselves. That duty matters when one person refinances, retitles or borrows against the house. Section 299(d) also lets partners who registered in California file for dissolution here even if neither now lives in the state. That point comes up for couples who have since moved away.
When the Family Home Is Community Property
A home bought during the marriage or registered domestic partnership, using earnings from that period, is community property under section 760. Each spouse or partner holds an equal one-half interest in it, regardless of whose name is on the deed or whose paycheck covered the mortgage.
Title adds a second layer. Family Code section 2581 presumes that property acquired during marriage "in joint form," such as joint tenancy, is community property for purposes of division. That presumption can be rebutted in only two ways the statute names. The first is a clear statement in the deed or title document that the property is separate. The second is proof of a written agreement that it is separate.
The community period has two boundaries. The first is the date of marriage or registration. The second is the date of separation. Family Code section 70 defines the date of separation as the date "a complete and final break in the marital relationship has occurred." Two things must both be true. One spouse has "expressed to the other spouse the intent to end the marriage," and that spouse's conduct is "consistent with the intent to end the marriage." The court considers "all relevant evidence." Under Family Code section 771, each person's earnings and accumulations after that date are their separate property. Mortgage payments made from post-separation wages can therefore be treated differently from payments made before.
At the end, Family Code section 2550 directs the court to divide the community estate equally. That rule applies "except upon the written agreement of the parties, or on oral stipulation of the parties in open court." Many couples resolve the house by settlement rather than leaving it to a judge, and the statute expressly allows that path. Family Code section 2552 adds that the court generally values assets "as near as practicable to the time of trial." For a home that has risen or fallen in value since separation, that rule can matter a great deal.
When the Home — or Part of It — May Be Separate Property
Family Code section 770 defines separate property as "all property owned by the person before marriage." It also includes property acquired during marriage "by gift, bequest, devise, or descent," along with the rents and profits of that property. In plain terms, that means things you owned going in, and gifts and inheritances you received along the way.
A home one person bought entirely before the marriage or registration starts out as that person's separate property. It does not turn into community property just because the couple lived there together. Under Family Code section 852, changing a property's character, which the law calls a transmutation, requires a writing. That writing must contain "an express declaration" made or accepted by the spouse whose interest is adversely affected. Adding a partner to the deed, or signing refinance papers, may or may not meet that standard. The answer depends on the documents themselves.
Commingling is where things get harder. Commingling means mixing separate and community money in the same account or asset. Picture a down payment that came partly from pre-relationship savings and partly from joint earnings. Or picture a remodel paid from an account holding both kinds of funds. Sorting out which dollars came from where is called tracing.
Family Code section 2640 governs one common version of this problem. When a home is community property but one person paid toward it with traceable separate funds, that person is generally reimbursed. Covered payments include a down payment, improvements or principal paydown, and reimbursement applies unless that person waived the right in writing. The reimbursement comes "without interest or adjustment for change in monetary values" and cannot exceed the property's net value. Interest, maintenance, insurance and property tax payments do not count. Section 2640(c) provides a similar reimbursement for separate funds put into the other spouse's separate property, unless a written transmutation or waiver exists.
The Proposition 8 Gap and Its Effect on Property Timelines
The date a relationship legally began is not always the date a couple would choose. In November 2008, California voters approved Proposition 8. It provided that only marriage between a man and a woman is valid or recognized in California. California allowed no new same-sex marriages from November 2008 until after Hollingsworth v. Perry was decided on June 26, 2013. That case decided standing only. The petitioners did not have standing to appeal the District Court's order, and the Ninth Circuit's judgment was vacated and remanded. Same-sex marriages in California resumed after that decision.
For couples who were together through those years, the legal record often looks like this. A home bought in, say, 2010, before the couple could marry, may sit outside the marriage entirely. But if the couple was registered as domestic partners at the time, the picture changes. Because of AB 205, partners have held the rights and duties of spouses since January 1, 2005, whenever they registered. Property acquired during a registered partnership in that period is analyzed under the same community property rules as property acquired during a marriage. For couples who registered before 2005, how earlier acquisitions are characterized is a separate, fact-specific question.
Many couples registered as domestic partners and later married each other. That leaves them with two legal relationships, not one. Family Code section 299(e) allows partners "who are also married to one another" to "petition the court to dissolve both their domestic partnership and their marriage in a single proceeding." The partnership did not end when the marriage began. As a result, the community period for the home may run across both relationships, and the court looks at the full timeline.
This history is often where same-sex property cases differ most from others. A registration certificate, a marriage certificate and a deed can each carry a different date. The home's character can shift depending on which date controls a given payment.
Options for the Family Home at Dissolution
Equal division under section 2550 does not require cutting the house in half. Equality is measured across the whole community estate. The home can be balanced against other assets, such as retirement accounts in divorce, or handled directly. Several paths come up regularly.
Buyout. One spouse or partner keeps the home and pays the other for their one-half community interest. Any section 2640 reimbursement is accounted for first. This often arises when one person has the income to carry the house alone and a strong reason to stay.
Sale and division of proceeds. The home is sold, and the net proceeds are divided equally after any separate-property reimbursement. This tends to arise when neither person can or wants to carry the property alone.
Deferred sale of home order. Family Code section 3800 defines a deferred sale of home order as an order that "temporarily delays the sale." It awards temporary exclusive use of the home to a custodial parent of a minor child. Its purpose is "to minimize the adverse impact" of the dissolution "on the welfare of the child." Under section 3801, the court first decides whether keeping up the mortgage, taxes, insurance and the home's condition is economically feasible. It considers factors including the resident parent's income and available support. Section 3802 then lists the factors the court weighs, including:
- how long the child has lived in the home
- the child's school placement
- any disability adaptations
- the emotional effect of a move
- each parent's ability to find suitable housing
- the tax consequences
- the economic detriment to the nonresident parent
For same-sex parents, this option connects directly to custody. A non-biological parent's standing as a legal parent can affect who is the custodial parent. Questions of parental rights in same-sex divorce often run alongside the housing question.
Continued co-ownership by agreement. Under section 2550, the parties can agree in writing to a different arrangement. That includes continuing to own the home together for a set period, then selling or buying out on agreed terms. Some couples addressed these questions years earlier in postnuptial agreements for same-sex couples, and those documents can shape the analysis.
Sometimes a judgment does not address the home at all. Family Code section 2556 gives the court continuing jurisdiction to divide community assets "omitted or not adjudicated by the judgment."
What Happens When Both Separate and Community Property Are in the Same Home
The most common mixed-character home looks like this. One person bought the house before the relationship, and joint earnings then paid down the mortgage for years. For this situation, California courts generally apply what is widely known as the Moore/Marsden calculation. The idea is that the community, by reducing the loan principal, buys into a proportional share of the house. The house still remains the owner's separate property in title and in origin.
In broad terms, the calculation works in three steps:
- Total the principal paid down with community funds during the community period. Interest, taxes and insurance do not count.
- Compare that total to the original purchase price to get the community's percentage.
- Apply that percentage to the home's appreciation during the community period. The community's share is the principal it paid plus that slice of appreciation.
The separate-property owner keeps their original down payment and the separate-property principal payments. They also keep the corresponding share of appreciation, including any appreciation before the relationship began.
This is a different situation from section 2640. Section 2640 reimburses separate money put into a home that is community property, without interest and without any share of appreciation. Moore/Marsden runs the other direction: community money goes into a home that is separate property, and the community does share in appreciation. Which framework applies depends on the home's character, and that can depend on the Proposition 8 and registration timeline described above.
Both calculations depend on records. Typical records include the closing statement from the purchase and the source of the down payment. They also include mortgage statements showing principal paydown over time, records of any refinance, and a current valuation of the home. The registration and marriage dates set where each payment falls. For many couples, the hardest part is rebuilding a paper trail from years when nobody expected to need one.
If You'd Like to Talk Through the History of Your Home
A family home in a same-sex divorce rarely has one clean start date. A consultation looks at the facts that drive the analysis. Those include when the home was bought, when you registered and when you married, where the down payment came from, how the mortgage was paid, how title is held, and whether children live in the home. The goal is a clearer picture of which framework likely applies, whether community ownership, section 2640 reimbursement or a Moore/Marsden share, and what records will matter most. Our practice is limited to California family law. For readers who simply want general background on the divorce process for same-sex couples, that page or the court's self-help resources may be a useful first stop.
