Separation Agreement

Also called: Marital Separation Agreement

What it means

A written contract between spouses who plan to live apart, settling the issues that would otherwise be decided in a divorce. The agreement covers property division, who keeps the house, who pays which debts, spousal support, and — if there are children — custody, visitation, and child support. New York requires the agreement to be in writing, signed, and acknowledged by a notary in the same form as a deed (DRL § 236(B)(3)). Once signed, the agreement is binding. After spouses live apart under a written separation agreement for at least one year, either spouse can use the separation as a ground for a no-fault divorce. Many couples skip the separation route and file a no-fault divorce directly. A separation agreement that was unfair when signed, or that one spouse signed without understanding, can sometimes be challenged. A lawyer-reviewed agreement is harder to undo than one drafted without legal advice.

When you might hear this

A separation agreement is a written contract between spouses who are living apart. It covers property, debts, support, and any issues involving children. Most separation agreements are used as the foundation for an uncontested divorce.

What to ask

  • Does the agreement need to be notarized in the same way as a deed?
  • How does the agreement affect a future divorce filing?
  • Can the agreement be changed after it is signed?
  • What happens if my situation changes — job loss, illness, a move?
  • Is it worth having a lawyer review the agreement before I sign?
