Safety orders and custody deadlines come first.
Domestic-violence, same-day custody, support-enforcement, and imminent-hearing issues should be flagged as urgent legal matters.
New Jersey palimony is narrow now. The timeline and the writing matter.
N.J.S.A. 25:1-5(h) requires a support promise in a non-marital relationship to be in writing and signed. The statute's independent-counsel requirement was held unconstitutional in Moynihan v. Lynch (2022). Older promises, property contributions, and cohabitation agreements need careful review before anyone assumes the answer is yes or no.
What we do. Pre-2010 oral palimony claim litigation; post-2010 cohabitation agreement drafting and review; alternative-theory analysis where palimony doesn't apply (contract, unjust enrichment, constructive trust, quantum meruit, joint property); cohabitation-related alimony modifications under N.J.S.A. 2A:34-23(n) source ; coordinated estate planning for cohabiting couples.
The 2010 watershed. New Jersey substantially restricted the traditional cohabitation-only palimony framework that Kozlowski v. Kozlowski source established. Current support promises must be in writing and signed by the party to be charged; the statute's independent-counsel requirement was held unconstitutional in Moynihan v. Lynch, 250 N.J. 60 (2022) source . Older promises may still need review, but the proof challenges grow as time passes.
The calls follow patterns. One partner says, "I gave up work because they promised I would be taken care of." Another says, "The house was only in their name, but I paid into it for years." A surviving partner is dealing with adult children who say there was never an agreement. A couple has lived together for years and wants the rules in writing before buying a home. These are not the same case. Palimony, cohabitation agreements, property claims, and estate-planning documents each answer different questions.
Palimony law in New Jersey underwent a major change after Kozlowski v. Kozlowski source . The current statute requires more formality for a non-marital support promise, and old informal arrangements become harder to prove as time passes. The work starts with the timeline, the documents, the property record, and the question the client actually needs answered: support, ownership, reimbursement, occupancy, estate protection, or a clean agreement before a dispute starts.
The Kozlowski source framework.
Under Kozlowski v. Kozlowski source , and subsequent cases including Crowe v. De Gioia source , NJ recognized palimony claims where:
- A promise -- express, written, oral, or implied from conduct -- to provide support.
- Marital-like consideration -- cohabitation, household services, financial contributions, foregone career opportunities.
- Detrimental reliance by the promisee.
Long-term cohabitation arrangements could produce enforceable palimony judgments. The doctrine was wider than it is now; many couples relied on informal arrangements without formal documentation.
The 2010 amendment -- N.J.S.A. 25:1-5(h) source .
The New Jersey Legislature amended the Statute of Frauds under N.J.S.A. 25:1-5(h) source to require a promise by one party to a non-marital personal relationship to provide support or other consideration to be:
- In writing.
- Signed by the party to be charged.
- Made with independent advice of counsel for both parties -- a requirement the New Jersey Supreme Court later held unconstitutional in Moynihan v. Lynch, 250 N.J. 60 (2022) source .
In Moynihan v. Lynch source , the Court struck the independent-advice-of-counsel condition as a violation of substantive due process under the New Jersey Constitution, holding that enforceability cannot be conditioned on attorney review. The writing and signature requirements survive. Oral promises between cohabitants made after the amendment therefore still face a Statute of Frauds problem if they are not reduced to a signed writing, which is why current planning should be documented before reliance grows around an informal promise.
Maeker v. Ross source and timing.
The New Jersey Supreme Court in Maeker v. Ross source addressed prospective application of the amendment. In practice, the litigation question often starts with when the alleged agreement was made, whether it was later modified, what proof exists, and whether separate equitable or property claims survive even if palimony does not.
Cohabitation agreements -- the modern path.
Cohabitation agreements are the cleaner planning path for unmarried partners who want financial expectations in writing. Typical components:
- Treatment of property acquired during cohabitation.
- Treatment of the residence -- title, mortgage contribution, separation/death disposition.
- Support upon separation -- none, time-limited, or ongoing.
- Treatment of business interests held during cohabitation.
- Estate-planning coordination -- wills, beneficiary designations, healthcare proxies.
- Children of the relationship (within statutory limits -- child support and custody remain under N.J.S.A. 9:17-38 source and N.J.S.A. 9:2-4 source ).
To satisfy N.J.S.A. 25:1-5(h) source , any support promise must be in writing and signed by the party to be charged. Independent counsel is no longer a condition of enforceability after Moynihan v. Lynch (2022), but separate counsel for each party remains sound practice. We draft cohabitation agreements as part of our relationship agreements practice.
Alternative theories -- when palimony doesn't apply.
Where palimony doctrine does not answer the problem, alternative theories may:
- Contract claims -- discrete agreements about specific property, contributions, or financial matters may be enforceable as ordinary contracts.
- Unjust enrichment -- restitution where one party has unjustly retained benefit at the other's expense.
- Constructive trust -- where one party holds property that equity dictates should belong to the other; common where one cohabitant funded acquisition or improvement of property in the other's name.
- Resulting trust -- where property was purchased with one party's funds but titled to the other.
- Joint-property claims -- partition or joint-property division for jointly titled property.
- Quantum meruit -- restitution for services provided with expectation of compensation.
Cohabitation and alimony -- N.J.S.A. 2A:34-23(n) source .
Cohabitation by an alimony recipient can produce termination or modification of alimony under N.J.S.A. 2A:34-23(n) source . Factors under the 2014 statutory framework and Konzelman v. Konzelman source include:
- Intertwined finances.
- Sharing or joint responsibility for living expenses.
- Recognition of the relationship in the couple's social and family circle.
- Living together; frequency of contact; duration of relationship.
- Sharing household chores.
- Whether the cohabitant has contributed to support obligations of the recipient.
- All other relevant evidence.
Cascading consequences can affect new partners. Moving in with an alimony recipient may trigger a termination or modification motion and can reorganize household finances. Contact counsel before cohabitation if existing alimony is part of the household economics.
Same-sex couples and palimony.
Palimony and cohabitation-agreement analysis applies regardless of gender. Counsel reviews the promise, timing, writing and signature, property record, and any later marriage or civil-union status. See our LGBTQ+ family law page for related family-law context.
Next step
If you are relying on an informal promise, separating after years of cohabitation, or planning to buy property with an unmarried partner, request a consultation before documents are signed or assets are moved. Bring any written agreement, deed, mortgage statement, bank records showing contributions, messages about support, and estate-planning documents so counsel can separate palimony from the other claims that may matter.
Frequently asked questions
Does New Jersey still recognize palimony?
Only narrowly. New Jersey's Statute of Frauds requires a promise by one party to a non-marital personal relationship to provide support to be in writing and signed by the party to be charged under N.J.S.A. 25:1-5(h)source. The statute's separate requirement that the agreement be made with independent advice of counsel was held unconstitutional in Moynihan v. Lynch, 250 N.J. 60 (2022)source, so counsel review is no longer required for enforceability. Older claims require careful timeline review under Kozlowski v. Kozlowskisource and later cases.
New Jersey palimony law changed sharply after the Legislature amended the Statute of Frauds. Before that change, Kozlowski v. Kozlowskisource recognized that unmarried cohabitants could, on the right proof, create enforceable support obligations through promises supported by consideration and reliance. Crowe v. De Gioiasource became part of that older framework. Today, N.J.S.A. 25:1-5(h)source requires the support promise to be in writing and signed by the party to be charged. The statute also required that the agreement be made with independent advice of counsel, but the New Jersey Supreme Court struck that counsel-review requirement as unconstitutional in Moynihan v. Lynch, 250 N.J. 60 (2022)source; the writing and signature requirements survive. Maeker v. Rosssource addressed prospective application of that amendment. A current claim usually turns on when the alleged promise was made, what documents exist, and whether non-palimony theories such as contract, unjust enrichment, constructive trust, resulting trust, or partition are available.
What about cohabitation agreements -- are they the same thing as palimony?
They are different, but related. A cohabitation agreement is a written contract that can address property, expense sharing, support, and estate-planning coordination for unmarried partners. If it includes a support promise, N.J.S.A. 25:1-5(h)source requires that promise to be in writing and signed. Independent counsel is no longer required for enforceability after Moynihan v. Lynch (2022)source, though separate counsel remains prudent.
Cohabitation agreements are the modern planning tool for unmarried partners who want financial terms in writing before a dispute. They can address ownership of property acquired during cohabitation, household-expense sharing, treatment of the residence, support upon separation, business interests, and estate-planning documents such as wills, beneficiary designations, healthcare directives, and powers of attorney. They cannot override a child's right to support or replace the court's custody analysis. Under N.J.S.A. 25:1-5(h)source, a support promise in a non-marital relationship must be in writing and signed by the party to be charged. Independent legal advice is no longer a condition of enforceability after Moynihan v. Lynch (2022)source, but the cleaner the disclosure and drafting -- and separate counsel remains sound practice -- the less room there is for a later fight about what was promised.
I cohabited for 15 years with my partner who promised to support me -- do I have any claim?
It depends on the timeline and proof. A pre-amendment promise may be analyzed differently from a later promise, and alternative theories may matter even when palimony is unavailable.
Long-term cohabitation alone does not create automatic support rights in New Jersey. The first question is when a specific support promise was allegedly made, what evidence proves it, and whether the claim falls inside or outside N.J.S.A. 25:1-5(h)source. Maeker v. Rosssource is the key prospective-application case. If the alleged promise is not enforceable as palimony, counsel still evaluates whether ordinary contract, unjust enrichment, constructive trust, resulting trust, partition, or quantum meruit theories fit the property and contribution facts.
What if I cohabit with someone and they have a prior palimony or support obligation to someone else?
Cohabitation can trigger termination or modification of alimony from a prior marriage under N.J.S.A. 2A:34-23(n). The Konzelman v. Konzelman framework guides whether 'cohabitation' rises to a level that terminates or reduces alimony. This affects the new partner -- moving in with someone who would lose their alimony can produce practical financial consequences that affect both partners.
Cohabitation can have cascading financial effects on prior support obligations. Cohabitation by an alimony recipient can produce alimony termination or modification under N.J.S.A. 2A:34-23(n)source. The 2014 amendments codified factors for evaluating cohabitation. Konzelman v. Konzelmansource remains part of the framework for marriage-like cohabitation. The party seeking termination or modification bears the initial burden of producing evidence. Different alimony forms can be affected differently, and the new partner generally owes no direct legal obligation to the recipient's ex-spouse. Still, household finances can change substantially. Contact counsel before cohabitation if existing alimony is part of either partner's financial picture.
What about same-sex couples and palimony?
Same-sex couples are governed by the same New Jersey palimony and cohabitation-agreement framework. The analysis turns on the promise, timing, writing, counsel, property facts, and any later marriage or civil-union status.
New Jersey's palimony and cohabitation-agreement rules are not limited by gender. The same core questions apply: Was there a support promise? When was it made? Is it written and signed? Are there property, contribution, or estate-planning facts that create separate claims? Independent counsel is no longer required for enforceability after Moynihan v. Lynch (2022), but separate counsel for each partner remains prudent. For couples who later married or entered a civil union, counsel also reviews whether the cohabitation period affects divorce, property, support, or estate-planning issues. The practical advice is the same for any unmarried couple: put financial expectations in writing and sign them, consider separate counsel, coordinate estate planning, and avoid relying on informal promises.
What about religious or cultural marriages not recognized civilly?
NJ recognizes civil marriages only -- religious or cultural ceremonies that aren't combined with a civil marriage license don't produce civil marital status. Parties who participated in religious-only ceremonies are legally cohabitants, not spouses, and the post-2010 palimony framework applies. Common situations: foreign religious marriages not registered civilly; religious ceremonies without civil license; common-law marriages from other states (NJ doesn't recognize common-law marriage formed in NJ but recognizes valid common-law marriages from other states).
Religious, cultural, foreign, and common-law-marriage issues require careful fact review. New Jersey civil marital status generally depends on a valid civil marriage, while a religious or cultural ceremony alone may leave the parties legally unmarried for divorce, equitable distribution, alimony, inheritance, and benefits purposes. New Jersey does not create a common-law marriage from cohabitation inside New Jersey, although a marriage validly formed elsewhere may raise recognition questions. If the parties are not civilly married, the palimony and cohabitation-agreement framework may apply, along with property-based theories such as contract, unjust enrichment, constructive trust, resulting trust, partition, or quantum meruit. Anyone relying on a non-civil ceremony should speak with counsel about a civil marriage, written cohabitation agreement, estate-planning documents, and parentage documents where children are involved.
