Postnuptial agreements are voluntary agreements made during an existing marriage laying out financial agreements that a couple may want to establish in the case of a divorce. If the agreements are fair and agreed upon by both parties, then the postnuptial agreement will be enforced in the event of the death or divorce of a spouse. However, if the agreement is found to be unconscionable, or extremely unfair,  then it could be thrown out.

A few other scenarios that may invalidate a postnuptial agreement include coercion, a spouse misrepresenting themself, or incomplete financial disclosure. If the postnuptial agreement is one-sided, the court may change certain aspects of the contract to ensure that both parties get a fair deal. 

Is a Postnuptial Agreement Right For You? 

There are several reasons why a couple may consider entering a postnuptial agreement. The primary role of a postnuptial agreement is to protect the spouses’ assets and ensure that assets are split relatively in the case of a divorce.  

Many couples make a prenuptial agreement that specifies provisions for a divorce before they are married. Premarital agreements can include a wide range of topics that can be discussed and agreed upon by both parties. Even though it is advised that every couple create a prenuptial agreement before getting married, many do not. 

The good news for such couples is that postnuptial agreements are recognized under Illinois law as well. The same conditions and concerns covered by prenuptial agreements are also covered by postnuptial agreements. The main distinction is that the contract is signed after the couple has already been married.

What is a Postnuptial Agreement?

Postnuptial contracts are binding agreements. Similar to agreements made prior to marriage, the couple determines in advance how the couple's joint property and spousal support would be handled in the event of a divorce. These agreements avoid court entanglement while sparing the couple the financial anguish of a contentious divorce. Postnuptial agreements can also make it simpler to decide what belongs to each party separately and what is marital property.

Prenuptial agreements are becoming more common in Illinois marriages. However, many people have never heard of a postnuptial agreement. Prenuptial and postnuptial agreements are actually quite similar; the main difference is that a prenuptial agreement takes place before a wedding, and a postnuptial agreement happens after the wedding has already happened.

If a couple is already married, it may seem odd to write a postnuptial agreement. But often, engaged couples are so busy planning the wedding that the less exciting financial elements of their relationship take a backseat. A postnuptial agreement is a way to address those issues that may have been overlooked during the honeymoon stage.

What is the Purpose of a Postnuptial Agreement?

Just like a prenup, a postnuptial agreement is a legal contract wherein spouses agree ahead of time on the way certain things will be addressed during the marriage and in the event of a divorce. One way postnuptial agreements do this is by determining what was “premarital property” – assets owned by only one spouse before the marriage – and what is “marital property” – assets acquired by both spouses during the course of the marriage.

A prenuptial agreement can be a great option for marrying couples who want to ensure that their financial assets are protected. However, some couples are reluctant to pursue a premarital agreement, possibly because of the awkwardness of thinking about divorce before the marriage even begins, or possibly because they feel they do not have sufficient assets for a prenuptial agreement to be necessary. For some of these couples, it may become apparent after the wedding that an agreement would be beneficial. Fortunately, married spouses have the option of establishing a postnuptial agreement.

What Can an Illinois Postnuptial Agreement Address?

A postnuptial agreement is often beneficial when a couple experiences a significant change in their financial situation during their marriage, perhaps due to an inheritance, a career opportunity, or the establishment of a new business. A postnuptial agreement can address many of the same issues as a prenuptial agreement, including:

• Each spouse’s property rights during the marriage, including ownership, use, management, and the ability to buy or sell.

  ...

Marriage is more than love and romance. The union is comprised of many facets, not the least of which is the financial component. One must remember that above all, marriage is a legal contract, and unless an agreement exists stating otherwise, “What is mine is yours" is the general rule that will be followed. Under Illinois law, any property or debt acquired during a marriage is considered marital property, meaning both parties have an equal claim to these assets in the case of divorce. Although this may seem trivial when everything is sunshine and rainbows during a marriage, it can be extremely detrimental should the union fail. To address these issues, a postnuptial agreement can protect your interests if your relationship encounters difficulty.

A Logical Look to the Future

A prenuptial agreement can document what should happen to assets and debts should the marriage result in divorce. Although the thought of the marriage failing before it even begins can be unromantic, logically, this is an ideal time for the discussion, especially given that approximately 50% of marriages result in divorce. When preparing to get married, you can civilly discuss the intimate details without the hostility associated with separation.

After “I Do,” It Is Not Too Late

For many Americans, a prenuptial agreement is either out of the question or regarded as unnecessary. However, as a marriage progresses, circumstances change that alter the family dynamic. In these cases, it is not too late to create a legal agreement to protect yourself. A postnuptial agreement is fundamentally identical to a prenup, except that it is created after the marriage vows. The contract can include any provisions the couple deems necessary, such as how assets will be divided or whether one spouse will pay spousal maintenance. Some spouses even choose to incorporate a clause regarding what should happen in the event of adultery, something the state does not include in divorce decisions.
