Every unmarried couple who has ever moved in together, split the rent, and told each other “we don’t need a piece of paper” owes a small debt to a Hollywood breakup that got very, very messy. In 1970, actor Lee Marvin ended his six-year relationship with singer Michelle Triola. She sued him for half of what he’d earned while they were together — about $1.8 million — arguing they’d built a life together the same way any married couple would. The case became a national sensation, gave the English language a new word (“palimony”), and created what California lawyers still call a Marvin claim.
But here’s the part that gets left out of most retellings: Michelle Marvin lost. Twice. And that’s actually the most useful part of the whole story for anyone wondering what a Marvin claim can — and can’t — do for them today.

What the California Supreme Court Actually Decided
In its 1976 decision, Marvin v. Marvin, the California Supreme Court didn’t award Michelle Marvin a dime — it simply ruled that she was entitled to have her case heard at all. Before Marvin, courts routinely threw out these cases on the theory that an unmarried couple’s arrangement was too tied up with sex to be a legitimate contract. The Supreme Court rejected that reasoning and held that unmarried partners can sue each other over express or implied agreements about property and support, so long as the agreement doesn’t depend solely on sex itself. That’s the whole precedent. It opened a courthouse door — it didn’t promise anyone a check on the other side.
What happened next proves the point. On remand, after an 11-week trial in 1979, the judge found that Lee Marvin and Michelle Marvin never actually had a contract, express or implied, to share his earnings. She got nothing on her core claim. The judge did award her $104,000 — not as “palimony,” but as a one-time “rehabilitation” payment to help her get back on her feet. Two years later, a California Court of Appeal threw out even that award, finding no legal basis for it. Lee Marvin ultimately paid nothing. The precedent survived; the plaintiff’s own case did not.
The Part Most People Get Wrong: There’s No Automatic Payout
The single biggest misconception we hear is some version of “we lived together for years, so I’m entitled to half.” That is exactly the theory the Marvin case rejected. California does not treat long-term cohabitation like a common-law marriage, and it never adopted the rule Michelle Marvin’s own trial court briefly considered — automatically splitting property just because two people lived together and “acted married.” The California Supreme Court went out of its way to say that theory went too far.
- What you actually need: a real agreement — written, spoken and clearly remembered, or reasonably implied by a specific pattern of conduct (for example, one partner leaving a career to run the household in direct exchange for lifetime support).
- What isn’t enough on its own: years together, shared a home, joint vacations, meeting each other’s families, or even the words “I’ll always take care of you” said in the heat of a good moment.
- The burden is on the person claiming the agreement existed, and without something in writing, that often turns into a swearing contest — which is exactly the kind of case that is hardest, slowest, and most expensive to win.
The Cases That Followed Marvin Mostly Lost, Too
Marvin opened the door in 1976, and for a while, lawyers and the press predicted a flood of copycat suits — one commentator warned “there are over 1,000 cases out there, so fellows beware.” A decade later, a Los Angeles Times retrospective found that the flood never really arrived, and the cases that did get filed mostly failed for the same reason Michelle Marvin’s did: no provable agreement.
- Marilyn Barnett v. Billie Jean King: Barnett, King’s former secretary, sued for lifetime support and a Malibu beach house. King filed an eviction suit instead, a court sided with King, and Barnett dropped the case.
- The Alfred Bloomingdale case: Vicki Morgan’s estate eventually won $200,000 based on specific written promises Bloomingdale had made — but the judge rejected her much larger palimony claim outright, warning that the Marvin decision was never meant to become what he called a “mistresses’ recovery act.”
- The Liberace case: Scott Thorson’s palimony claim against the entertainer was dismissed on similar grounds — courts will not enforce an agreement that amounts to payment for sex.
The pattern holds up almost 50 years later: a Marvin claim can work, but only when there’s a real, provable agreement about property or support — not simply a long, loving relationship.
A Modern Marvin Claim: Bryan Johnson v. Taryn Southern
Marvin claims aren’t just a 1970s relic — they’re still being filed today, including in the tech world. In October 2021, actress and content creator Taryn Southern sued biotech entrepreneur Bryan Johnson (best known for his multimillion-dollar anti-aging regimen) in Los Angeles Superior Court. According to the court record, her complaint alleged — in almost exactly these words — breach of an express oral or implied Marvin agreement for lifelong financial support, and breach of a Marvin agreement to share assets, including equity in his company.
The two met in 2016, moved in together within four months, and were engaged by 2018. Southern claimed Johnson repeatedly promised to take care of her financially and medically “for the rest of her life,” and that she gave up her own career to support his ventures in reliance on those promises. She alleged that in 2019, while she was undergoing treatment for stage III breast cancer, he had her move out of the home they had shared for three years.
Johnson denied the allegations. The case went to arbitration, and in March 2023 the arbitrator dismissed all of Southern’s claims and ordered her to pay Johnson’s attorneys’ fees — $584,199.16, later confirmed by a Los Angeles Superior Court judge. Johnson publicized the result himself, calling the suit an extortion attempt; Southern’s allegations were never adjudicated on their underlying merits at a public trial, since her claims were resolved through a signed release and arbitration rather than a judge or jury ruling on whether a Marvin agreement actually existed.
Whatever one makes of the underlying dispute, the legal lesson is the same one Marvin itself teaches: an unmarried partner can absolutely bring one of these claims — the door the 1976 case opened is still very much open — but simply proving the relationship existed, and even proving real promises were made in the heat of the moment, is not the same as proving an enforceable contract. That gap is where most Marvin claims, then and now, end up failing.
It’s Filed in Civil Court — Not Family Court
This surprises almost everyone. Because a Marvin claim isn’t a divorce (there was never a marriage to dissolve), it isn’t filed in family court and it doesn’t follow family law procedure. It’s a civil breach-of-contract case, filed like any other contract dispute, decided under ordinary contract and equity principles rather than California’s community property or spousal support statutes. That distinction affects everything from which forms you file, to what a judge can and can’t order, to how long the case can take.
It also means a Marvin claim can never decide child custody, visitation, or child support — those issues, when a couple has children together, are handled separately in family court regardless of whether the parents were ever married.

If You’re Building a Life With Someone — Married or Not
Whether you’re trying to protect what you’ve built, or trying to prove what you were promised, the time to get clarity is before there’s a dispute, not after. A short, clearly written cohabitation agreement can do for an unmarried couple what a prenup does for a married one — and it can prevent the exact fight Michelle and Lee Marvin had. If a breakup has already happened and you believe there was a real promise on the table, we can help you evaluate whether you have a claim worth pursuing.
