Palimony is financial support that one partner may seek from the other after a long-term, unmarried relationship ends. It is grounded in contract law, not family law, which means a court will not award it just because two people lived together for years. The person asking for support has to prove that an actual agreement for financial support existed between the partners, and whether that claim can even be heard depends on the state.
How Palimony Differs From Alimony
Alimony flows from the legal rights created by marriage. When a marriage ends, a court has statutory authority to order one spouse to support the other. Palimony has no such built-in authority. There is no federal palimony law, and in states that recognize it, the claim is treated as an ordinary breach of contract dispute between two private people who happened to be in a relationship.
The concept traces back to the 1976 California Supreme Court decision in Marvin v. Marvin. Michelle Marvin lived with actor Lee Marvin for several years without marrying and sued when the relationship ended, alleging the couple had agreed to share equally in property they accumulated. The court held that unmarried adults who live together “are nonetheless as competent as any other persons to contract respecting their earnings and property rights.” That ruling opened the door for courts around the country to enforce financial agreements between unmarried partners, within one important limit the same opinion established: a contract between unmarried partners is enforceable only if it is not “explicitly founded on the consideration of meretricious sexual services.”1Justia Law. Marvin v. Marvin In plain terms, the agreement has to be about something other than exchanging sex for money.
What You Have to Prove
Because palimony is a contract claim, you have to show a contract existed. Courts recognize three forms, and the type of agreement dramatically affects how hard the case is to win.
A written agreement is the strongest foundation. A signed cohabitation agreement laying out how assets would be divided or whether one partner would provide support is treated much like any other written contract. These documents do not have to be elaborate, but they do need clear terms.
An oral agreement is harder to prove but still enforceable in most states. If your partner verbally promised to support you and you can show what was promised, that spoken agreement can anchor a claim. “I’ll always take care of you” is probably too vague for a court to enforce. “I’ll pay the mortgage and your living expenses as long as we’re together” gives a judge something concrete to work with.
An implied agreement is the most difficult to establish. Nothing was ever said explicitly; the claim rests on how the couple actually behaved. If one partner gave up a career to raise children or manage the household so the other could build a business, a court might infer a shared understanding that the working partner would provide financial security in return. These cases live or die on circumstantial evidence.
Where You Live Decides Whether You Have a Claim
Palimony is a state-by-state matter, and the differences are stark.
Many states follow the framework set by Marvin v. Marvin and allow contract-based claims between former partners. The analysis is straightforward contract law: was there an agreement, what were the terms, and did one side breach it? The court does not have to find that the relationship resembled a marriage, only that a valid contract existed.
Some states require the agreement to be in writing. New Jersey amended its statute of frauds in 2010 to provide that a promise by one partner in a non-marital relationship to support the other is unenforceable unless it is in writing and both parties had independent legal counsel when the agreement was made.2New Jersey State Library. New Jersey Revised Statutes 25:1-5 The counsel requirement is unusual and makes a casual handshake deal nearly impossible to enforce. Texas takes a similar approach, requiring agreements made “on consideration of nonmarital conjugal cohabitation” to be in writing and signed.3State of Texas. Texas Business and Commerce Code 26.01 – Promise or Agreement Must Be in Writing Without a signed document, a Texas court will not hear the claim.
Washington recognizes “committed intimate relationships” instead of traditional palimony. When one of these relationships ends, a court can divide property and debts acquired during the partnership but cannot order ongoing financial support. You might get half the house, but you will not get monthly checks.
Illinois historically rejected palimony outright. In 1979, the state Supreme Court ruled that granting property rights to unmarried cohabitants raised public policy concerns about undermining marriage.4Justia Law. Hewitt v. Hewitt More recent Illinois decisions have shown greater willingness to hear claims under other legal theories, but the state remains more restrictive than most.
A separate avenue exists in states that recognize common-law marriage. If you can prove a common-law marriage, you gain the full rights of a legally married spouse at separation, including potential spousal support. That is a different claim from palimony because it rests on marital status rather than contract.
The Sexual Services Defense
The most common defense in a palimony case is that the agreement was really about exchanging sex for financial support. If a court concludes the contract rested entirely on sexual services as consideration, it will refuse to enforce it. This rule applies in essentially every state that recognizes palimony.
The key word is “entirely.” A contract between unmarried partners remains enforceable as long as some portion of the consideration is independent of the sexual relationship. A California appellate court put it directly: if one partner provided services as a secretary, business partner, or homemaker, those contributions can support the contract even if a sexual relationship also existed.5Justia Law. Whorton v. Dillingham The contract fails only if it is “inseparably” based on sexual services with no independent value exchanged.
Practically, the partner defending the claim will try to characterize the relationship as purely romantic, while the one bringing it needs to show concrete contributions beyond the relationship itself: homemaking, career support, financial contributions, child-rearing. The more tangible those contributions, the weaker this defense becomes.
Evidence That Actually Wins These Cases
The burden sits entirely on the person bringing the claim. Vague expectations and hurt feelings will not do it.
Financial records are the strongest evidence short of a signed contract. Joint bank accounts, shared credit cards, co-signed loans, and property titled in both names show the couple treated their finances as intertwined. Being named as a beneficiary on a partner’s life insurance or retirement account points to a long-term commitment beyond casual dating.
Written communications can substitute for a formal agreement. Text messages, emails, and letters where your partner discussed financial promises or acknowledged a support arrangement create a paper trail. A single text saying “I’ll make sure you’re taken care of” is not a contract by itself, but combined with other evidence it helps build the picture of a real understanding.
Witness testimony matters too. Friends, family members, or colleagues who heard your partner make financial promises or who can describe how the couple handled money together add credibility a court can weigh.
Evidence of personal sacrifice is particularly powerful in implied-contract cases. If you left a job, paused an education, or relocated to support your partner’s career, documenting those choices and their financial impact shows a court that your contributions had real economic value. A partner who gave up a $60,000-a-year career to manage the household for a decade has a compelling story. A partner who kept working independently and maintained separate finances has a much weaker one.
What a Court Can Award
When a court finds a valid agreement existed and was breached, it generally has two options.
Direct financial support can take the form of a lump sum or periodic payments. Courts awarding periodic support often structure it to help the dependent partner get back on their feet, similar to rehabilitative spousal support in a divorce. The amount and duration track what the agreement actually promised, what the claimant gave up, and what the paying partner can afford.
Property division is the other main remedy. If the agreement covered shared ownership of a home, investments, or other assets, a court can order a distribution based on the contract’s terms. There is no automatic equal split; the division follows what the partners agreed to, or in an implied-contract case, what the court decides is fair based on each person’s contributions.
Some states also allow claims based on equitable theories like unjust enrichment even without a contract. If one partner received a substantial benefit from the other’s contributions and keeping that benefit without compensation would be unjust, a court can order restitution. That is a separate theory from palimony, but it can produce similar results.
Filing Deadlines
Because palimony is a contract claim, the statute of limitations for breach of contract applies. The clock generally starts when the relationship ends and the alleged breach occurs.
Written contract claims usually carry longer deadlines than oral ones. In many states, the deadline for a written contract breach is four to six years, while oral contract claims often must be filed within two to three years. These windows vary significantly by state, and missing the deadline almost certainly means losing the right to bring the claim.
Some states apply a “discovery rule” that delays the start date until you knew or should have known about the breach, but this is not universal. If a long-term relationship just ended and you believe your partner broke a financial promise, talking to an attorney sooner rather than later is the safer move.
Claims After a Partner’s Death
A partner’s death does not automatically end a palimony obligation. Courts in several states have allowed palimony claims to proceed against a deceased partner’s estate, reasoning that a lifetime promise of support is no different from any other contract the person made while alive.
Not every state agrees, and a few do not recognize these claims against an estate at all. Where they are allowed, the surviving partner has to prove a valid agreement existed and was breached, just as in any other palimony case. The estate then becomes responsible for satisfying the obligation out of its assets.
If your partner dies without a will and you were never married, you generally have no automatic right to inherit anything. A palimony claim is one of the few legal avenues available, but it requires the same evidentiary foundation as any other. For unmarried couples with significant shared assets, estate planning documents and a written cohabitation agreement provide far more reliable protection than hoping a court will sort things out later.
