What is the Difference Between a Prenup and a Postnup?

Prenuptial and postnuptial agreements are legal documents that are becoming increasingly popular in today’s society. These agreements allow couples to define their rights and responsibilities before and after marriage, respectively.
In this article, we will discuss the key differences between prenuptial and postnuptial agreements, including the legal requirements for each, the enforceability of each agreement, and the types of issues that can be addressed in each agreement. We will also provide a brief overview of the laws in the state of New York that apply to these agreements.
What is a Prenuptial Agreement?
A prenuptial agreement, also known as a “prenup,” is a legal contract that is entered into by two people before they get married. The purpose of a prenup is to outline the rights and responsibilities of each spouse in the event of a divorce or death. Prenups typically address issues such as property division, alimony, and inheritance rights.
In New York, prenuptial agreements are governed by the New York Consolidated Laws GOB § 3-303. Under New York law, a prenuptial agreement must be in writing, signed by both parties, and notarized. The agreement must also be entered into freely and voluntarily, without coercion or undue influence. Additionally, the agreement cannot be unconscionable and must be fair at the time of execution.
Each party should also have an opportunity to consult with an independent attorney before signing the agreement.
What is a Postnuptial Agreement?
A postnuptial agreement, also known as a “postnup,” is a legal contract that is entered into by two people after they are already married. The purpose of a postnup is to outline the rights and responsibilities of each spouse in the event of a divorce or death, just like a prenup. Postnups typically address the same types of issues as prenups, such as property division, alimony, and inheritance rights.
In New York, postnuptial agreements are also governed by the law. The same requirements for prenuptial agreements apply to postnuptial agreements, including that the agreement must be in writing, signed by both parties, and notarized. Additionally, the agreement must be entered into freely and voluntarily, without coercion or undue influence. Furthermore, the postnup must be executed voluntarily and without coercion. The agreement cannot be unconscionable and must be fair at the time of execution.
Each party should also have an opportunity to consult with an independent attorney before signing the agreement.

Key Differences between Prenups and Postnups
While prenuptial and postnuptial agreements have many similarities, there are some key differences between the two.
- Timing: The most obvious difference between prenuptial and postnuptial agreements is the timing of when they are executed. Prenups are entered into before marriage, while postnups are entered into after marriage.
- Enforceability: Prenuptial agreements are generally considered to be more enforceable than postnuptial agreements. This is because a prenup is entered into before the marriage, while a postnup is entered into after the marriage. This means that the parties are less likely to claim that they were coerced into signing the agreement. However, both types of agreements are subject to the same legal requirements, and both prenups and postnups have the same chances of being upheld in court as long as they meet all legal requirements.
- Changes in Circumstances: Another key difference between prenuptial and postnuptial agreements is that postnups are generally easier to modify than prenups. This is because postnups are entered into after the marriage, when the couple’s circumstances may change from time to time. In contrast, prenups are often more difficult to modify, as they are entered into before the marriage and are based on the couple’s circumstances at that time.
Types of Issues Addressed
Both prenuptial and postnuptial agreements can address various issues, including property division, alimony, and inheritance rights. However, some issues are typically addressed in prenups, and others are typically addressed in postnups.
Prenups typically address:
- Property rights and ownership.
- Division of assets and liabilities in the event of a divorce.
- Alimony and spousal support.
- Inheritance rights.
- Waiver of the right to elect against a will or trust.
- Agreement on the terms of a divorce, in the event that one occurs.

Postnups typically address:
- Changes in financial circumstances since the marriage.
- Clarification of property rights and ownership.

- Agreement on how to handle future disputes.
- Agreement on the terms of a divorce, in the event that one occurs.
- Agreement on the terms of estate planning, including the distribution of assets upon death.
