Same-Sex Divorce and Property Division in New York: When Your Marriage Started Before It Was Legal

New York legalized same-sex marriage through the Marriage Equality Act, which took effect on July 24, 2011. The U.S. Supreme Court extended that right nationwide in Obergefell v. Hodges in 2015. Since then, same-sex spouses divorce under the same Domestic Relations Law that governs every other New York divorce, including the equitable distribution rules in DRL §236(B).

Equitable distribution means the court divides marital property fairly — which is not the same as equally. New York is not a community-property state, so there is no automatic 50/50 split. Instead, a judge weighs a list of statutory factors to reach a result the court considers fair. Marital property generally includes whatever the spouses acquired from the date of the marriage until the date the divorce is commenced. Separate property — what each person owned before the marriage, plus gifts and inheritances received individually — normally stays with the spouse who owns it.

Here is where the standard rules collide with the lived experience of many same-sex couples. Because marital property is measured from the wedding date forward, the years a couple spent together before they could legally marry usually fall outside the marital estate. A house one partner bought in 2004, an investment account opened in 2008, a business launched in 2009 — if these were acquired before the 2011 wedding, they often start out as that partner’s separate property, even though the couple treated everything as “ours” for years.

New York does not recognize common-law marriage; the state abolished it in 1933. Living together, sharing expenses, and presenting as a couple do not create a legal marriage no matter how long they last. And New York courts do not automatically backdate a marriage to the start of the relationship. So a couple together for twenty-five years but legally married for only a few may find that a large share of what they built is, on paper, separate property belonging to whichever partner’s name is on the title.

The starting point is not the finish line. Property that began as separate can take on a marital character — in whole or in part — through what the couple did over the years. Common ways this happens include:

• Joint titling. Adding a partner’s name to a deed or a bank account is strong evidence that the asset was meant to be shared, and it can convert separate property into marital property.
• Commingling. When separate funds are mixed with marital funds so thoroughly that they can no longer be traced — for example, a pre-marriage savings account that both spouses paid into for years — courts may treat the account as marital.
• Appreciation tied to effort. If the value of a separate asset grew during the marriage because of a spouse’s contributions or marital funds — paying down a mortgage, renovating a home, helping build a business — the increase in value can be subject to distribution.
• Reimbursement and credit claims. Even when an asset stays separate, the marital estate may be entitled to a credit for marital money spent improving or maintaining it.

Proving these points depends on records: deeds, closing statements, account histories, and a clear timeline of who paid for what. The further back the relationship goes, the more those old documents matter.

The wedding-date problem reaches beyond property. New York ties the suggested duration of spousal maintenance to the length of the marriage, again measured from the legal wedding date. Under the statutory advisory ranges, a marriage of up to fifteen years suggests maintenance for roughly fifteen to thirty percent of its length; the percentages rise for longer marriages. A couple together for two decades but legally married for five could see a much shorter suggested maintenance window than their actual partnership would imply.

The advisory schedule is a guideline, not a straitjacket. Courts keep discretion to adjust the amount and duration based on the facts, and the circumstances of a long pre-marriage partnership are exactly the kind of factor a judge can consider. Raising it well — with evidence and a clear narrative — is part of advocating for a fair result.

No single argument erases the wedding-date gap, but several tools can soften it:

• The catch-all equitable factor. New York’s equitable-distribution statute lets a court consider “any other factor” it finds just and proper. A long, committed relationship that predates a legally available marriage, and each partner’s contributions during those years, can be argued under this provision.
• Careful tracing. A forensic accountant or a well-documented timeline can show how separate and marital funds intertwined — turning a vague sense of unfairness into a concrete, provable claim.
• Prenuptial and postnuptial agreements. For couples who are not yet divorcing, a prenuptial or postnuptial agreement is the cleanest way to define what is separate, what is shared, and how to credit the years spent building a life before the wedding.
• Negotiated settlement. Most of these cases are resolved by agreement, not trial. A settlement lets both spouses account for the full history of the relationship in a way a strict reading of the statute might not.

If children are involved, custody and support are decided under New York’s ordinary standards, but same-sex parents should also confirm that both legal parent-child relationships are secure. We cover that in our companion article on LGBTQ parental rights in New York.
