A postnuptial agreement is a document that a married couple creates to determine what happens to their joint and separate assets and financial responsibilities in the event of a divorce. This document is very useful when the spouses prioritize transparency and certainty regarding their marital financial future.

In this text, we will explore answers to questions such as:

  • Is a postnuptial agreement legally binding?

  • How long after marriage can you get a postnuptial agreement?

  • What cannot be included in a postnuptial agreement?

For answers to these questions and much more, read on. 

What is a Postnuptial Agreement?

A postnuptial agreement, or just postnup, is a legal contract that partners create after they are officially married to regulate financial matters. It is important to note that the purpose of the postnuptial agreement is to address issues related to the division of the property and debts, both marital and separate, in the event of divorce or the death of one spouse.

Therefore, the spouses cannot use this document to decide on child-related issues such as child custody, child support and visitation rights. This issue will be discussed by the judge when it comes to the divorce, not prior to it.

However, to be effective, a postnuptial agreement must be based on the parties' good faith, honesty, and complete disclosure of all the property and money they own, as well as their debts. Only in that case can the judge determine if the postnup is fair so it can be legally binding.

Otherwise, either party can ask the court to decide that a postnuptial agreement favors one spouse to avoid its enforcement. In that case, the judge will apply the statutory rule of property division.  

Postnuptial vs. Prenuptial Agreement

Postnuptial agreement and prenuptial agreement present similar terms as they serve the same purpose—to outline how the partners' property, assets, debts, and business interests will be divided in the event of divorce, legal separation, or death, but they are created at different stages of marriage.

So, the main difference between these two similar documents is that partners create a prenuptial agreement before getting married, while a postnup is made after they get officially married.

Because of this, a prenuptial agreement focuses more on the property the partners bring into the marriage and how they will manage those assets. Of course, that doesn't prevent spouses from using a prenuptial agreement to address marital financial matters. 

Beyond that, there are no other differences between these documents.

What Information Goes on a Postnuptial Agreement

Information that goes into a postnuptial agreement encompasses details about the parties involved and their agreement concerning property and finances. 

Let's delve into these several vital components:

Postnuptial Agreement Elements

  • Parties involved. The agreement begins by clearly identifying the spouses, detailing their full names, current addresses, and contact information.

  • Financial disclosure. This section outlines each spouse's present financial status. It encompasses details such as income (salary and other sources), assets (real estate, vehicles, investments, and personal belongings), and liabilities (debts, mortgages). It also addresses any changes in financial circumstances since the marriage began.

  • Spousal support (alimony). This part of the agreement allows spouses to specify financial support arrangements one will provide to the other in case of separation or divorce. It includes terms like the duration, amount, and method of payment.

  • Division of assets and debts. This section outlines how marital property and debts will be allocated in the event of divorce or death. It defines what constitutes separate versus marital property, clarifying what each spouse brought into the marriage and what was acquired jointly.

  • Amendments and clauses. Postnuptial agreements often include additional provisions and clauses tailored to the spouses' specific needs and preferences. These provisions can cover dispute resolution mechanisms (such as a jurisdiction clause), conditions for modifying or terminating the agreement, and other relevant matters.

When Should You Make a Postnuptial Agreement?

You should make a postnuptial agreement when certain circumstances arise that make managing critical financial matters within the marriage more logical and secure. This is often the case when one or both spouses bring their wealth into the marriage and wish to preserve it as separate property.

Also, if one spouse starts a business during the marriage, they can use a postnuptial agreement to regulate how the business will be handled if the marriage ends. Postnups are also used when a spouse expects to receive a significant inheritance and wants to clearly define that it will remain their separate property.

Besides these reasons, spouses may choose to use a postnuptial agreement in other situations when they want to have peace of mind and avoid any conflict in the event of divorce.

How to Create a Postnuptial Agreement?

To create a postnuptial agreement, you can start with our professional Contract.net postnuptial agreement builder, which allows you to tailor the document to your needs. 

The next step is to fill out the document by outlining the following information:

#1. Enter Personal Details

Start by entering the essential personal information about both spouses, such as full names, current addresses, and contact information.

#2. List Assets and Debts

Each spouse must provide a detailed list of their assets, which covers everything from bank accounts and real estate to investments and vehicles.

As we said, transparency is key to a postnuptial agreement. Both spouses must fully and precisely disclose their financial situation, including property they owned before marriage and property acquired during the marriage.

Otherwise, they risk a judge assessing that their agreement is not fair, which may lead to not accepting it, so the court will apply state law.

#3. Define Business Interests

If either spouse owns a business, it is important to include terms regarding its management. Decide whether the business will remain separate or be considered marital property, which will be divided between spouses in the event of divorce.

#4. Clarify Debt and Tax Responsibilities

It is not all about the assets and the property—the spouses should determine how existing debts and tax obligations will be handled. Given that, agree on who will pay off loans, mortgages, and other liabilities.

Addressing these issues in advance helps avoid financial strain and administration or court disputes later on. 

#5. Decide on Living Arrangements and the Marital Home

The marital home can be a sticky point. To avoid it, discuss what will happen to it in the event of legal separation or divorce. Decide whether the house will be sold (and how the money will be divided), kept by one spouse, or divided (if applicable).

#6. Sign and Notarize Postnup

The last and mandatory step is to sign and notarize the postnup to make it valid. So, both spouses have to sign a postnuptial agreement in the presence of the notary public. Before signing, the parties should go through the document once again to make sure everything is according to their agreement.

Pros of Making a Postnuptial Agreement

The pros of making a postnuptial agreement are as follows:

Pros of a Postnuptial Agreement

  • Clarity in financial responsibilities. After experiencing married life and gaining insight into each other's financial habits and attitudes, it's easier to approach this type of contract. By regulating the financial and property aspects, spouses ensure clarity on their financial rights and responsibilities.

  • Preservation of family assets. This agreement helps safeguard family wealth, ensuring that assets and inheritances remain within the family lineage. This advantage is particularly beneficial for protecting children from previous marriages by clearly defining their inheritance rights and preventing assets from being divided in the event of a divorce. 

  • Enhanced marital stability. Discussing and agreeing on financial matters can strengthen communication and trust between spouses, which can improve overall marital stability and reduce the likelihood of misunderstandings regarding finances and property.

Cons of Making a Postnuptial Agreement

Despite its benefits, a postnuptial agreement has several drawbacks:

Cons of a Postnuptial Agreement

  • Potential strain on relationships. Introducing discussions about a postnuptial agreement can create tension and distrust, especially if one spouse feels pressured or caught off guard.

  • Enforceability challenges. Laws governing postnuptial agreements vary by jurisdiction, and courts can reject certain provisions if they are deemed unfair or unreasonable.

  • Emotional impact. Negotiating financial terms and preparing for a potential divorce can be emotionally draining. This impact is heightened if one spouse has a significantly stronger financial position, potentially leading the other spouse to feel vulnerable and hurt.

4 Mistakes To Avoid When Making a Postnuptial Agreement

To ensure a postnuptial agreement is effective, fair, and enforceable, we provide you with a list of the most common mistakes to avoid when making a postnuptial agreement.

Postnuptial Agreement Mistakes

  • Incomplete disclosure. A postnuptial agreement must fully disclose all assets, debts, income, and financial obligations of both spouses. Failure to disclose everything can lead to challenges in court, as the agreement may be viewed as unfair or unenforceable.

  • Lack of legal review. The spouses should have a separate lawyer review the postnuptial agreement. Without independent legal advice, spouses might not fully comprehend their rights and the agreement's implications, or the terms can be unfairly advantageous to one spouse, potentially resulting in the agreement being invalidated by a court.

  • Lack of mutual consent. If one spouse pressures the other into signing the agreement through direct threats, emotional manipulation, or other means of undue influence, the court can invalidate the agreement. Both parties must agree willingly and voluntarily for it to be legally binding.

  • Legal formalities. According to state laws, postnuptial agreements must adhere to specific legal formalities and requirements to be enforceable. These typically include being in writing, signed by both parties and, in some cases, notarized or witnessed by neutral third parties to ensure validity. 

Final Thoughts

Once you're married to your loved one, understanding each other's financial situations is crucial for building trust, making joint financial decisions, and planning for the future together.

Whether there are inheritances, children from previous relationships, or a desire to manage financial aspects comprehensively—not just in the case of divorce or separation but also for the sake of your children and in the event of death—a postnuptial agreement can provide a practical solution.

While not the most romantic choice, approaching a postnuptial agreement sensibly and with the mutual consent of both spouses, guided by impartial legal advice, allows you to manage your financial arrangements and address future uncertainties effectively.
