Free Cohabitation Agreement Template

A cohabitation agreement is a written contract between two unmarried partners who live together, or plan to, that sets out how they will handle property, income, shared expenses, debts, and other practical matters during the relationship and if they later separate or one partner dies. It functions much like a prenuptial agreement, but with one important difference: it does not require marriage to take effect. The moment both partners sign, the agreement governs the financial side of the relationship.

The reason these agreements matter is that, in nearly every U.S. state, simply living together does not give a couple the legal rights and protections that married spouses receive. Cohabitation by itself does not create a marriage, and most states have abolished common-law marriage. As a result, an unmarried partner generally has no automatic claim to property held in the other partner's name, no automatic right to inherit, and no statutory right to support if the relationship ends. A cohabitation agreement fills that gap by letting the couple define their own rules in advance.

The legal foundation for these contracts traces to the landmark California case Marvin v. Marvin (1976), in which the California Supreme Court held that unmarried partners may enter into enforceable agreements regarding property and support, provided the agreement is not founded on the exchange of sexual services. Most states now follow some version of this reasoning and treat a cohabitation agreement as an ordinary contract, enforceable so long as it meets standard contract requirements. The result coined the popular term "palimony" to describe support-like awards between unmarried partners.

A cohabitation agreement is worth considering any time two people share a home and combine some part of their finances without being married. The need grows stronger as the financial stakes increase. The following situations are the most common.

Moving in together is the natural starting point. When partners begin sharing rent or a mortgage, utilities, groceries, and furniture, a written agreement clarifies who pays what and who owns what, preventing arguments about shared responsibilities later.

Buying property together raises the stakes considerably. If one partner contributes a larger down payment, or only one name appears on the deed or lease, the agreement can document each partner's ownership share so that contributions are honored if the couple separates. Without this, courts often default to title ownership and ignore uncredited contributions.

Unequal income or assets is another strong trigger. When one partner earns significantly more, owns a business, has substantial savings, or expects an inheritance, both partners benefit from clarity about what stays separate and what is shared.

Protecting children from a prior relationship and existing estate plans is a frequent motivation for older couples and those entering second relationships. The agreement can confirm that separate property remains separate and is preserved for intended heirs.

Blending finances, opening joint accounts, co-signing loans, or making major joint purchases all create entanglements that are far easier to untangle when the rules were written down at the outset. In every case, the goal is the same: replace uncertainty and assumption with clear, mutually agreed terms.

A thorough cohabitation agreement should address every area where the partners' finances and property overlap. The clauses below form the backbone of an effective agreement and mirror the sections in the template above.

Drafting a strong cohabitation agreement is a step-by-step process that rewards thoroughness and honesty. Working through the following stages helps ensure the finished document is both complete and enforceable.

Start with full financial disclosure. Each partner should prepare an honest list of their assets, debts, and income and share it with the other. Courts are far more likely to enforce an agreement when both partners entered it with a clear picture of the other's finances, and concealment is one of the leading reasons agreements are later thrown out.

Next, identify the parties and the shared residence with specificity, using full legal names and addresses. Then work through each financial category in turn: separate property, joint property, household expenses, bank accounts and debts, major purchases, and pets. For every category, decide the rule that fits your situation and state it in plain, specific language. Avoid vague terms like "fair share" in favor of concrete percentages, dollar amounts, or formulas.

Address what happens on separation. Spell out notice requirements, how joint property and debts will be divided, deadlines for inventory and removal of belongings, and whether any temporary support applies. Add a dispute-resolution clause that requires negotiation and mediation before either partner files suit.

Finish with the formalities. Include a clause confirming both partners disclosed their finances and had the opportunity to seek independent legal advice, a governing-law clause naming your state, and an amendments clause requiring changes to be in writing. Both partners then sign and date the agreement, ideally before a notary. Using a structured template like the one above keeps the process organized and ensures no critical section is overlooked.

For a cohabitation agreement to hold up in court, it must satisfy ordinary contract-law requirements as well as the special rules that apply to agreements between unmarried partners. The exact rules vary by state, so reviewing your own jurisdiction's law, or consulting a local family-law attorney, is strongly advised.

The agreement should be in writing and signed voluntarily by both partners. Most states require a written contract for arrangements involving real estate, and a signed writing is far easier to enforce than an oral understanding. Both partners must enter the agreement freely, without coercion, fraud, or duress.

Full and fair financial disclosure is essential. Each partner should disclose their material assets, liabilities, and income before signing. The agreement should also be supported by valid consideration, meaning each partner gives up or promises something of value. Critically, under the Marvin v. Marvin rule followed by most states, the agreement cannot be founded on sexual services as consideration; a clause tying the contract to a sexual relationship can render it unenforceable.

State law differs significantly. California broadly enforces both express and implied agreements between unmarried partners under Marvin. Illinois takes a much more restrictive view: in Hewitt v. Hewitt (1979), the Illinois Supreme Court refused to enforce a marriage-like property and support claim between cohabitants on public-policy grounds, though express written contracts on specific property are treated more favorably. Because of these differences, a governing-law clause naming your state is important.

Notarization is generally not legally required, but having both signatures notarized adds authenticity and helps defend the agreement if it is later challenged. Independent legal advice for each partner further strengthens enforceability.

Even well-intentioned couples can undermine their cohabitation agreement by overlooking a few recurring pitfalls. The mistakes below are among the most damaging.
