Planning a wedding or already married and thinking ahead? Collins Law Group, PLLC is a prenuptial & postnuptial agreements lawyer NYC couples trust to protect what they’ve built before the wedding or years into the marriage.

Prenuptial & Postnuptial Agreements Lawyer NYC

A prenuptial agreement is a contract you sign before marriage. A postnuptial agreement is the same kind of contract, signed after marriage. Both spell out who keeps what — homes, savings, a business, an inheritance — if the marriage ends. In New York, either one can also set spousal support terms, but neither can decide child custody or child support. A solid agreement, written by a prenup attorney NY couples can rely on, usually takes two to six weeks to complete when both sides act in good faith.

Here’s a short example. Say you own a small business before you marry. Without an agreement, if you divorce, a court could treat part of that business’s growth during the marriage as shared property. With a prenuptial agreement, you and your spouse decide in advance that the business stays yours. Clear terms, no guessing, no fight later.

Why Couples Across NYC Come to Collins Law Group

You want a lawyer who has handled real cases like yours – not a generic form. We serve clients in Manhattan, Westchester, Long Island, and the surrounding boroughs, and we build every agreement around your actual life: your income, your family, your property, and your goals. We answer your questions the same day you ask them, and we tell you plainly if something in a draft agreement won’t hold up in court.

Prenup Attorney NY: What We Handle

As your prenup attorney NY family works with, we draft agreements that cover the real things people worry about before a wedding:

  • Keeping a home, apartment, or investment property as separate property
  • Protecting a business, medical practice, or professional license you built before marriage
  • Setting expectations for spousal support if the marriage ends
  • Protecting an inheritance or gift meant for you or your children
  • Outlining how debt brought into the marriage stays with the person who owes it
  • Setting rules for how you’ll handle money during the marriage, like joint accounts or shared expenses


We also represent the spouse who is asked to sign a prenup. If someone hands you an agreement to review, you need your own lawyer – not theirs. We’ll read every line, tell you what’s fair, what’s not, and negotiate changes on your behalf.

Postnuptial Agreement Lawyer NY: When You Need One

Life changes after the wedding. Maybe you started a business. Maybe you received an inheritance. Maybe trust needs rebuilding after a hard year. A postnuptial agreement lawyer NY couples turn to can put new terms in writing at any point during the marriage – not just before it.

Common reasons married couples come to us for a postnup:

  • One spouse started or grew a business after the wedding
  • A large inheritance or gift arrived and needs to stay separate
  • One spouse gave up a career to raise kids and wants income protection written down
  • The couple is working through trust issues and wants clear financial terms going forward
  • A couple wants to update or replace a prenup that no longer fits their life


A postnuptial agreement works the same way a prenup does under New York law. Both spouses must fully disclose their finances, both need their own lawyer, and both must sign willingly, without pressure.

Marital Agreement Attorney NY: How We Protect Your Assets

As a marital agreement attorney NY spouses hire for both prenups and postnups, we focus on one thing: making sure your agreement actually protects you. New York divides property “equitably,” not automatically in half. Without a written agreement, a judge decides what’s fair, based on many factors and that outcome is never guaranteed.

A well written marital agreement removes that guesswork. It tells the court, clearly, what you and your spouse already agreed to. That means:

  • Faster, calmer outcomes if the marriage ever ends
  • Lower legal costs later, since fewer things are in dispute
  • Real certainty for your business partners, family, or children from a prior relationship
  • Protection for the lower-earning spouse too, through fair spousal support terms

Prenup Law Firm NY: Our Simple, Honest Process

As a prenup law firm NY couples describe as easy to work with, here’s exactly what happens when you hire us:

  1. Free call. We talk through your situation, your assets, and your timeline. No pressure, no jargon.
  2. Financial disclosure. Both spouses share a full, honest list of what they own and owe. This step protects the agreement from being thrown out later.
  3. First draft. We write the agreement in plain language, matched to your goals.
  4. Review and negotiation. Your spouse’s lawyer reviews it. We go back and forth until both sides agree the terms are fair.
  5. Signing. Both parties sign in front of a witness, with time to consider the terms – never rushed.


Most agreements are ready in two to six weeks. If your wedding is close, tell us early – we can move faster.

Marriage Contract Lawyer NY: What Makes an Agreement Enforceable

A marriage contract lawyer NY residents trust will tell you the truth: not every prenup or postnup holds up in court. New York judges look for five things:

  • The agreement is in writing and signed properly, with a witness
  • Both spouses had their own lawyer, not one lawyer for both
  • Both spouses shared their full financial picture, honestly
  • Nobody signed under pressure, threats, or a rushed deadline
  • The terms were fair when the agreement was signed


Templates you find online almost always miss one of these five requirements. When that happens, a judge can throw out the whole agreement – which means you get no protection at all, right when you need it most. We build every agreement to meet all five standards from day one.

Asset Protection Lawyer NY: What You Can and Can't Protect

As an asset protection lawyer NY families call before a wedding or after a big financial change, here’s what a prenup or postnup can protect:

  • Homes and real estate you owned before marriage
  • A business, practice, or professional license
  • Retirement accounts and investments from before the marriage
  • Inheritances and family gifts
  • Intellectual property, like a patent or a book you’re writing


Here’s what New York law says a prenup or postnup
cannot decide: child custody and child support. Those decisions are always made based on the child’s needs at the time, not locked in years earlier. Any lawyer who tells you otherwise isn’t giving you accurate advice.
