Prenuptial & Postnuptial Agreements

Prenuptial & Postnuptial
Agreements

Whether entering a marriage or reassessing one already in place, clear financial agreements can preserve both assets and peace of mind. Prenuptial and postnuptial agreements serve as essential legal tools defining rights, obligations, and expectations.

At Bikel Rosenthal & Schanfield, we assist in drafting, negotiating, and litigating prenuptial and postnuptial agreements in complex, high-conflict cases involving intricate assets, family businesses, international holdings, and emotionally charged dynamics.

The "Relationship Ahead of Time" Approach

Too often, prenuptial agreements are framed solely as preparations for divorce.
We advocate a different perspective: a Relationship Ahead of Time strategy.

Rather than viewing prenups as a signal of mistrust, responsible couples view these agreements as a framework for honest discussion, long-term planning, and mutual respect. Prenuptial agreements encourage partners to clarify financial values and expectations early, an exercise that can strengthen the relationship.

Tips for Constructive Prenup Conversations:

  • Start early: Avoid last-minute negotiations that feel pressured or adversarial.
  • Review together: Discuss each clause openly to build mutual understanding.
  • Use neutral language: Focus on planning, not protecting against your partner.
  • Involve separate counsel: Having each party receive independent legal advice ensures fairness and impartiality.

What Can a New York Prenup or Postnup Do?


Prenuptial and postnuptial agreements are binding contracts that can shape how assets and obligations are handled during marriage, in the event of separation or divorce, or upon the death of one of the parties. The contents can be highly customized to the needs of the couple.

Key functions include:

  • Define separate vs. marital property: Preserve individual ownership of premarital assets, gifts, inheritance, and specific property acquired during the marriage.
  • Allocate debt: Ensure responsibility for student loans, business liabilities, or personal debts remains clearly assigned.
  • Clarify maintenance and support obligations: Define whether spousal support (maintenance) will be paid, and under what terms.
  • Protect business and family interests: Maintain clear boundaries for business equity, partnerships, gifts, or inherited wealth, including family-run or multigenerational enterprises.
  • Plan for future assets: Account for anticipated income, investments, or property purchases not yet acquired at the time of marriage.

New York courts generally uphold these agreements if properly executed. However, drafting a valid and enforceable prenuptial agreement (prenup) or postnuptial agreement (postnup) requires careful adherence to legal standards and the use of strategic language.

At Bikel Rosenthal & Schanfield, our Manhattan-based attorneys ensure that your agreement reflects your priorities and withstands future scrutiny.  You can learn more about these marital agreements in our Guide to Prenuptial and Postnuptial Agreements.

Why Prenups and Postnups Matter in High-Conflict Cases

In marriages where emotional, financial, or reputational stakes are high, a well-drafted agreement can be a critical safeguard. We represent clients involved in high-conflict situations such as:

  • Public or media-sensitive divorces
  • Cross-border marriages with conflicting jurisdictional rules
  • Family disputes over trusts or inheritance
  • Businesses with multiple owners or legacy planning
  • Complex asset portfolios or hidden financial histories

In these cases, prenuptial and postnuptial agreements can help reduce courtroom battles, limit costly discovery, and preserve privacy. Drafted carefully, prenups and postnuptial agreements provide a legal framework that limits ambiguity and exposure.

Challenging or Enforcing a Prenuptial Agreement


Marital agreements are not immune to dispute. Whether you're seeking to uphold a prenup or contest one, the matrimonial attorneys at Bikel Rosenthal & Schanfield offer strategic representation grounded in an extensive understanding of New York family law.

Common grounds for challenging a prenup or postnup include:

  • Fraud or concealment: A spouse fails to disclose all relevant assets or income at the time of signing.
  • Improper execution: The agreement wasn't properly signed, witnessed, or documented in accordance with New York law.
  • Unconscionable terms: The agreement is grossly one-sided, leaving one party without reasonable support.
  • Duress or coercion: One spouse was pressured or manipulated into signing the agreement, especially shortly before a wedding.

Courts analyze these claims on a case-by-case basis. A single issue, such as incomplete disclosure, may not be sufficient to overturn an agreement, but multiple issues may render a prenuptial agreement invalid.

Our attorneys evaluate the totality of your circumstances and offer honest, clear guidance on the strength of your position.

Postnuptial Agreements: A Legal Option During Marriage

Some couples choose to formalize financial terms after marriage. Postnuptial agreements function similarly to prenups but are executed after the wedding. They may be used when:

  • Financial circumstances have changed significantly (e.g., business growth or inheritance)
  • One spouse is taking on disproportionate financial risk or responsibility
  • The couple wants to protect children from prior relationships
  • The parties want to reaffirm or revise terms from a prenup

Postnups can be helpful tools for reducing tension, clarifying expectations, or offering reassurance during periods of strain or transition.
