What Is Palimony in California?
A California Family Law Attorney’s Guide to Support for Unmarried Partners
The Direct Answer
Palimony is financial support that one unmarried partner may be ordered to pay the other after their relationship ends, based on an express or implied agreement to provide support rather than on marital status. California does not recognize common-law marriage, so unmarried partners do not have the same rights as spouses under Family Code community property laws. However, under the principles established in Marvin v. Marvin, a partner who can prove that the couple had an express oral or written agreement, or an implied agreement based on conduct, to share property or provide support may recover damages or ongoing support after separation. Palimony claims are contract claims, not family law claims, and are filed in civil court rather than family court. The agreement must be supported by consideration other than sexual services, meaning the partners must show they pooled resources, performed services, or made sacrifices in reliance on the agreement.
Why Palimony Exists in a No Common-Law State
California abolished common-law marriage in 1895. Since then, unmarried couples who live together do not acquire the legal rights and obligations of married couples, regardless of how long they cohabit or how intertwined their lives become. This means that when an unmarried couple separates after decades of shared finances, joint property acquisitions, and mutual sacrifices, neither partner can walk into family court and demand community property division or spousal support.
Palimony was created to fill this gap. The California Supreme Court in Marvin v. Marvin held that unmarried partners can make enforceable agreements about property and support, and that courts will enforce these agreements under standard contract principles. The key is that there must be an agreement. Cohabitation alone, no matter how long, does not create palimony rights.
This distinction matters in Los Angeles and Santa Monica, where many couples choose to live together indefinitely without marrying. Some avoid marriage for tax reasons, some for philosophical reasons, and some simply never get around to it. When these relationships end, the financial consequences can be as severe as a divorce, but the legal remedies are different and harder to access.
At Hayat Family Law, we handle palimony claims for unmarried partners who have separated after long-term cohabitation. We also defend against palimony claims when the alleged agreement never existed. These cases require careful documentation of the couple’s financial arrangements, communications, and conduct during the relationship.

Court: Civil court, not family court
Based on California contract law and Marvin v. Marvin
The Marvin v. Marvin Framework
The 1976 California Supreme Court decision in Marvin v. Marvin created the legal foundation for palimony. The case involved actor Lee Marvin and his partner Michelle Triola Marvin, who lived together for six years without marrying. When they separated, Michelle claimed that Lee had promised to support her for life and that she had given up her career in reliance on that promise.
The Supreme Court held that unmarried partners can enter enforceable contracts regarding property and support, provided the contract is not based on sexual services. The court rejected the traditional rule that cohabiting couples could not make legally binding agreements about their financial relationship. The decision opened the door for unmarried partners to seek remedies similar to divorce, but only when they can prove an agreement.
The Marvin framework requires three elements. First, there must be an agreement, express or implied, to share property or provide support. Second, the agreement must be supported by consideration other than sexual services. Third, the partner seeking enforcement must have relied on the agreement to their detriment, such as by giving up a career, contributing labor to the other partner’s business, or pooling financial resources.
Express Agreements vs. Implied Agreements
Palimony claims can be based on express agreements or implied agreements. Each type requires different proof and faces different challenges.
An express agreement is a direct statement or writing in which one partner promises to support the other or share property. Express oral agreements are enforceable but difficult to prove because they often become he-said-she-said disputes. Express written agreements, such as cohabitation agreements or property-sharing contracts, are much stronger and easier to enforce.
An implied agreement is inferred from the couple’s conduct during the relationship. Courts look at whether the partners pooled their finances, purchased property together, made joint financial decisions, or conducted themselves as if they were married. The longer the cohabitation and the more intertwined the finances, the stronger the inference of an implied agreement.
However, implied agreements are harder to prove than express agreements. The partner seeking palimony must show that the conduct was specifically intended to create financial obligations, not just the natural result of living together. Sharing a bank account might support an implied agreement, but it might also just be convenience.
The Consideration Requirement
The most important limitation on palimony is the requirement that the agreement be supported by consideration other than sexual services. This means that the partner seeking support cannot base their claim solely on the fact that they had a sexual relationship with the other partner.
Valid consideration includes financial contributions, domestic services, career sacrifices, business assistance, and emotional support. If one partner gave up a promising career to raise the couple’s children while the other partner built a business, the career sacrifice is valid consideration. If one partner managed the household, handled finances, or provided labor to the other partner’s business, these services are valid consideration.
The consideration requirement prevents palimony from becoming a backdoor form of common-law marriage. It ensures that palimony is based on economic interdependence and mutual sacrifice, not on the mere fact of a romantic relationship.
Cohabitation Agreements: The Best Protection
The strongest palimony protection is a written cohabitation agreement signed by both partners. These agreements function like prenuptial agreements for unmarried couples. They specify how property will be owned, how expenses will be shared, and whether one partner will support the other if the relationship ends.
Cohabitation agreements are enforceable under California contract law, provided they meet the basic requirements of contract validity: mutual consent, consideration, and lawful purpose. They do not need to be notarized or witnessed, though notarization strengthens the evidence that both parties signed voluntarily.
Unmarried couples who acquire significant assets together, such as real estate in Los Angeles or Santa Monica, should strongly consider a cohabitation agreement. Without one, property disputes after separation are governed by general property law, not family law, and the partner who contributed less financially may have no claim to the home they shared for years.
Property Division for Unmarried Couples
Unmarried couples do not have community property rights. When they separate, property division is governed by general property law principles, primarily the law of joint tenancy, tenancy in common, and resulting or constructive trusts.
If the couple purchased real estate together and both names are on the deed as joint tenants, each partner owns half and can force a sale or buyout. If only one partner’s name is on the deed, the other partner may claim a resulting trust if they contributed to the purchase price, or a constructive trust if they were promised an ownership interest.
Personal property, bank accounts, and vehicles follow similar rules. If both names are on the account or title, the property is jointly owned. If only one name is on the title, the other partner must prove a trust or agreement interest to claim a share. These claims are civil actions, not family law matters, and are filed in the civil division of the superior court.
Frequently Asked Questions
Quick Answers on Palimony
Q1: Does living together for 10 years create palimony rights?
No. Cohabitation alone, regardless of duration, does not create palimony rights in California. You must prove an express or implied agreement to share property or provide support. The length of cohabitation is evidence of an implied agreement but is not sufficient by itself.
Q2: Can I get palimony if we never had a written agreement?
Yes, if you can prove an implied agreement based on conduct. Courts look at whether you pooled finances, made joint purchases, or relied on promises of support to your detriment. Oral agreements are also enforceable if you can prove them with credible evidence.
Q3: Is palimony the same as alimony?
No. Alimony is spousal support under Family Code Section 4320 and applies only to married couples. Palimony is a contract-based remedy for unmarried couples. The legal standards, procedures, and courts are different.
Q4: Can same-sex couples claim palimony?
Yes. Palimony applies to all unmarried couples regardless of gender or sexual orientation. Since same-sex marriage became legal in California, many same-sex couples who were together for decades before marriage may have palimony claims from the pre-marriage period if they never formalized their relationship.
Q5: What evidence proves an implied agreement?
Evidence of an implied agreement includes joint bank accounts, joint property purchases, joint tax filings, one partner’s career sacrifice for the other’s benefit, and testimony about promises made during the relationship. The more your financial lives were intertwined, the stronger the implied agreement claim.
Q6: Can I get half the house if we bought it together but only my partner’s name is on the deed?
If you contributed to the purchase price or mortgage payments, you may have a resulting trust claim that entitles you to a proportional share. If your partner promised you an ownership interest and you relied on that promise, you may have a constructive trust claim. These are civil claims, not family law matters.
Q7: How long do I have to file a palimony claim?
Palimony claims are contract claims subject to the statute of limitations for written or oral contracts. In California, the statute of limitations for written contracts is four years, and for oral contracts it is two years. The clock typically starts running from the date of separation or from the date the agreement was breached.
Q8: Can a cohabitation agreement be challenged?
Yes, on the same grounds as any contract: fraud, duress, undue influence, or lack of capacity. A cohabitation agreement can also be challenged if it is unconscionable, meaning it is so one-sided that no reasonable person would have agreed to it. Courts review these challenges under standard contract law principles.
Q9: Does having children together strengthen a palimony claim?
Having children together does not automatically create palimony rights, but it strengthens the evidence of an implied agreement. If one partner gave up a career to raise the children while the other built a business, the career sacrifice is strong consideration supporting a palimony claim. Child support is a separate issue governed by Family Code Section 4053.
Q10: Should unmarried couples get a cohabitation agreement?
Yes, if they acquire significant assets together, share finances, or want to clarify their rights upon separation. A written cohabitation agreement eliminates the uncertainty of proving implied agreements and provides clear rules for property division and support. It is the best protection for both partners.
What Unmarried Couples in California Should Know
Unmarried couples in California have no automatic rights to each other’s property or support. The law treats them as independent individuals whose financial relationship is governed by contract and property law, not family law. This can produce harsh results when long-term relationships end and one partner is left with nothing despite years of contribution.
Palimony is the remedy, but it is not guaranteed. It requires proof of an agreement, consideration beyond sexual services, and detrimental reliance. These are legal hurdles that many partners cannot clear, particularly if the relationship was informal and undocumented.
The practical advice is simple. If you are living with a partner and sharing finances, get a cohabitation agreement. If you are buying property together, put both names on the title. If you are making career sacrifices for the relationship, document them. The law protects married couples automatically. It protects unmarried couples only when they take steps to protect themselves.
