Differences Between a Prenuptial Agreement vs. Postnuptial Agreement

Marriage is a personal commitment, but it is also a legal and financial partnership. A married couple blends their assets, debts, business interests, and future obligations. Many couples find it worthwhile to evaluate and address how these matters will be handled if the marriage ends or when one spouse dies. Prenuptial and postnuptial agreements offer couples a way to clarify their wishes and protect their legal and financial interests.

However, the timing of the agreement matters. Understanding how South Carolina courts will evaluate a prenuptial agreement vs. postnuptial agreement, and what they cannot address, helps couples make informed decisions about whether a prenuptial agreement or postnuptial agreement is right for them.

Key Takeaways:

• Timing is the primary difference between a prenuptial agreement vs. a postnuptial agreement. A prenuptial agreement is signed before the wedding, while a postnuptial agreement is signed after a couple is married.
• Because spouses owe one another fiduciary duties, South Carolina courts analyze postnuptial agreements more closely than prenuptial agreements. When deciding whether the agreement is enforceable, they consider whether both spouses had full knowledge of the couple’s finances, whether the agreement was voluntary, and whether its terms are fair.
• Prenuptial and postnuptial agreements can address potential legal issues between a couple such as asset protection, debts, liabilities, spousal support, business interests, and estate planning matters. They cannot address child custody or child support.
• To be enforceable, a prenuptial or postnuptial agreement must be in writing and signed by both parties, entered into voluntarily and supported by full financial disclosure, and reasonably fair at the time it was signed.

Understanding Prenuptial Agreements and Postnuptial Agreements

Prenuptial and postnuptial agreements are legal documents that provide clarity and protection for prospective spouses and married couples. These contracts are increasingly common and are used to manage financial matters, property rights, and other issues that may arise between a couple if the marriage ends. They can also be used in connection with an estate plan when one spouse dies.

What Is a Prenuptial Agreement?

A prenuptial agreement, also known as a “prenup,” is a contract signed before marriage that outlines how a couple will handle financial matters during the marriage, in the event of divorce, and after the death of one spouse. They are negotiated before a couple is married, when the potential spouses are independent and have not yet taken on the legal obligations of marriage.

What Is a Postnuptial Agreement?

A postnuptial agreement is similar to a prenuptial agreement and can address many of the same issues, such as property division, debts, and spousal support, but it is signed after a couple is married.

Key Differences Between a Prenuptial Agreement vs. a Postnuptial Agreement

The key difference between a prenuptial agreement vs. a postnuptial agreement is when the document is signed. Prenuptial agreements are executed before a couple marries, while postnuptial agreements are signed after a couple is married.

Because postnuptial agreements are signed after a couple is married and legally owe fiduciary duties to one another, South Carolina courts examine them more closely to ensure neither spouse has exploited the marital relationship to gain an unfair advantage. Courts will consider whether both spouses have full knowledge of the couple’s finances, whether the agreement was truly voluntary, and whether the terms of the agreement are fair given the marital relationship.

Prenuptial and postnuptial agreements are contracts and must be supported by consideration, or something of value, to be enforceable. In a prenuptial agreement, that consideration is the marriage itself. Each party agrees to the prenuptial agreement in exchange for the other’s agreement to marry. South Carolina courts have found that the mutual promises in a postnuptial agreement are enough to provide adequate consideration. But this is a legal issue that must be considered.

What Can a Prenuptial Agreement or a Postnuptial Agreement Address?

Prenuptial and postnuptial agreements can cover a wide range of issues. Specifically, they can be used to address:

• Asset protection. Couples can use a prenuptial or postnuptial agreement to protect individual assets acquired before or during the marriage. These agreements can help a couple avoid disputes by defining marital and separate property, ensuring each spouse retains their separate assets in the event of divorce.
• Allocation of debts. A prenuptial or postnuptial agreement can clarify which debts belong to each spouse and how debts incurred before marriage will be handled. This can prevent one spouse from being responsible for the other’s debt if the couple divorces.
• Liability protection. These agreements can protect one spouse from the other’s financial liabilities by clearly defining each spouse’s financial obligations. However, these provisions do not limit the rights of third-party creditors.
• Spousal support terms. Couples can agree in advance on whether and how spousal support will be paid in the event of a divorce. Defining these terms early can avoid uncertainty and conflict. However, courts will not enforce terms that are unconscionable or would leave one spouse unable to meet their basic needs.
• Business interests. A prenuptial or postnuptial agreement can protect a business owned by one spouse or both spouses. The agreement could establish that the business is to remain separate property, limit a spouse’s claim to ownership or management, and address how the business will be valued or divided if the marriage ends.
• Inheritance and other estate planning concerns. Couples can use a prenuptial or postnuptial agreement to preserve an inheritance, family heirlooms, or other assets they wish to pass on to children from a prior relationship or to other family members. An agreement can also specify what each spouse will receive upon the other’s death.
• Life insurance and retirement accounts. A prenuptial or postnuptial agreement can address ownership and beneficiary designations of life insurance policies, IRAs, 401(k)s, pensions, and other retirement accounts. However, federal laws, like ERISA, may impose additional requirements.

Both agreements are subject to the same limitations and cannot address child support or child custody matters. They also cannot include terms that are unconscionable.

What Are the Legal Requirements for a Valid Prenuptial or Postnuptial Agreement?

In South Carolina, prenuptial and postnuptial agreements are enforceable as long as they satisfy the following requirements:

• The agreement must be in writing and signed by both parties.
• Both parties must fully disclose their financial assets and liabilities. Failure to do so can make the agreement unenforceable.
• Both parties must enter the agreement voluntarily, without coercion or undue pressure.
• An agreement can favor one party, but it must be reasonably fair to both so as not to be “unconscionable” at the time it was signed.

South Carolina courts will generally uphold and enforce a prenuptial or postnuptial agreement that satisfies these requirements.
