What is a New Jersey Postnup?

Postnuptial agreements, also called post marital agreements, are legally binding contracts that couples execute after entering a marriage. The purpose of this agreement is primarily financial planning in case the couple decides to separate or divorce. In addition, a marital agreement can also address how finances will be handled throughout the marriage and what happens if one spouse dies.

Hiring an attorney to draft a postnuptial agreement is highly recommended. An experienced family law attorney will be familiar with what terms belong in a marital agreement and what issues cannot be included. A lawyer can help ensure that your agreement is legally binding and will be held up in court.

Do I Need a Postnuptial Agreement in New Jersey?

Most people believe that only those who are wealthy need a postnuptial agreement, however this is not necessarily true. Every married couple with assets, debts, a business, or children from a previous relationship can benefit from a well drafted postnuptial agreement.

New Jersey divorce courts follow the principles of equitable distribution. This means that property attained during a marriage will not be split equally in a divorce. Instead, a family court judge will determine how to divide the property so that it is fair and equitable based on each spouse’s contribution.

Some factors that judges will look at to determine how to distribute property include:

  1. Length of the marriage
  2. Age and health of each spouse
  3. Education and earning potential of each spouse
  4. Whether either spouse helped further the other’s career or education
  5. If there are children, who is the primary caretaker

A valid postnuptial agreement will override state property distribution laws and outline a couple’s customized plans for their assets and liabilities.

What's Typically Included in a New Jersey Postnuptial Agreement

Every postnuptial agreement must include a full disclosure of assets and liabilities to be legally valid. Assets can include real property, investment accounts, business assets, trusts, retirement benefits and foreign assets. If either spouse fails to disclose assets, the other spouse could challenge the legality of the agreement due to fraud or unconscionability.

In addition to a full financial disclosure, the following provisions are typically included in most New Jersey postnuptial agreements

  • Property classification and division. A comprehensive list of what property is marital, what property is separate, and how marital property will be divided in the event of a divorce or separation.
  • Spousal support. Terms of any spousal support that one spouse may be entitled to including the amount and duration of payments.
  • Debt allocation. How debts and liabilities incurred during the marriage will be allocated between the spouses. This is especially important if either party entered the marriage with a large amount of debt and marital funds were used to pay the debt.
  • Inheritance. Inheritance and gifts are typically separate property. However, to protect these assets, they should be included in a postnuptial agreement. If either spouse has a child from a previous relationship, inheritance for heirs can also be included in the agreement.
  • Business interests. If either spouse owns a business, the agreement can address how the business will be divided or valued in the event of a divorce or separation.
  • Legal fees. The agreement can outline how legal fees will be handled in the event of a divorce or separation.

When couples have children, they usually add provisions about child support and child custody to their marital agreement. In some cases, courts will honor the terms, however the court will also reserve the right to modify child support and custody terms. Courts are obligated to ensure that the interests of a child are protected. Marital agreements cannot waive child support for one spouse or limit visitation rights.

Postnuptial Agreement Drafting in New Jersey

Hiring an attorney to draft a postnuptial agreement is highly recommended. A family lawyer will be familiar with New Jersey law and know what can and cannot be included and enforced in a New Jersey postnuptial agreement.

Before drafting a marital agreement, the lawyer will consult with the couple to learn about their financial situation and future plans. The attorney will then draft an agreement that implements the spouse’s requested terms.

Postnuptial Agreement Review in New Jersey

Some couples choose to draft their own postnuptial agreement without help or legal advice from an attorney. While this is an option, having a lawyer review the document ensures that it follows all New Jersey laws and that it will be held up in divorce court.

A lawyer can also assist a couple in understanding all the terms of the contract and what rights, if any, they may be surrendering. Under New Jersey law, couples must have sufficient time to review the agreement, or it could be overturned in court.

"Hired LeMont for a compliance review — a claim I was about to print and an agreement I was about to sign. He asked good questions before starting instead of guessing at my facts, and one of them caught a real gap in my own draft. Where the law was unsettled he told me what he'd do rather than stopping at "it depends," which is the entire reason I hired a lawyer instead of trying to read the statutes myself. He also surfaced something my own research had missed entirely. He flagged an issue he could easily have billed me to analyze, and told me to wait until it was actually a problem. Delivered on time, at the flat fee quoted, no surprises. I'll be hiring him again."

Hi, I'm Randy, and I've been practicing law for over 30 years with a genuine passion for contracts and legal drafting. I spent nearly 15 years running my own solo practice in Richmond, Virginia, where I built a thriving firm helping everyone from small business owners to entertainment professionals navigate their legal needs. Those years taught me that great contracts aren't just about covering all the bases legally - they're about understanding what my clients actually need and translating that into clear, enforceable agreements. My sweet spot is contract drafting across a wide range of areas. I've written hundreds of LLC operating agreements (both single and multi-member), prenuptial and postnuptial agreements, residential and commercial leases, independent contractor agreements, service contracts, NDAs, consulting agreements, and corporate formation documents. I also have extensive experience in estate planning documents - wills, trusts, powers of attorney, and living wills - plus employment agreements and entertainment law contracts. These days I'm based in New York City, but I work with clients nationwide on contract matters. What I love most about this work is taking complex business relationships and turning them into documents that actually make sense and protect everyone involved. Whether you're a startup founder needing your first operating agreement or an established business updating your contractor templates, I focus on creating contracts that work in the real world, not just on paper. After three decades of practice, I still get excited about a well-crafted contract. Let's talk about how I can help with yours.
