Whether you are planning for marriage or have been married for years, a marital agreement can provide clarity, protect your assets and business interests, and help prevent unnecessary conflict if circumstances change. This guide explains how prenuptial and postnuptial agreements work in Tennessee and how to decide which one fits your situation.

Prenuptial and postnuptial agreements are legal contracts between spouses that establish how certain financial matters will be handled during the marriage or if the marriage ends. They can address property division, debt allocation, spousal support, and the treatment of separate versus marital property. The key difference is timing: a prenuptial agreement is signed before the wedding, while a postnuptial agreement is signed after the couple is already married.
The two agreements work in much the same way and are evaluated under similar principles. What differs is when they are signed and why couples typically choose them.
| Prenuptial Agreement | Postnuptial Agreement | |
|---|---|---|
| When it is signed | Before the wedding | After the wedding |
| Why couples choose it | To set financial expectations and protect assets before marriage | To address changes during marriage, such as a new business, inheritance, or career change |
| Takes effect | Upon marriage | Upon signing |
| Common focus | Separate property, debts, business interests, spousal support | Assets and businesses acquired or grown during the marriage, updating prior terms |
| Can it be changed later? | Sometimes, if both spouses agree in writing | Sometimes, if both spouses agree in writing |
Generally, yes. When properly drafted, voluntarily signed, and compliant with Tennessee law, both prenuptial and postnuptial agreements are usually enforceable. Courts look closely at whether each spouse had a fair opportunity to review the agreement, whether financial disclosures were adequate, and whether the agreement was signed freely, without pressure, fraud, or coercion. Terms found to be unconscionable or the product of duress or misrepresentation may not be enforced.
Identifying and protecting separate property, such as assets owned before marriage, inheritances, or property acquired during the marriage.
Clarifying responsibility for debts incurred before and during the marriage.
Protecting a business interest from being treated as marital property subject to division, including how growth in value will be handled.
Establishing in advance how property will be divided if the marriage ends.
Addressing whether support will be paid and under what terms, subject to what Tennessee law and the court allow.
Reviewing terms proposed by the other party, negotiating changes, and updating an existing agreement as circumstances evolve.
Courts keep authority over matters involving children. Provisions about child custody, parenting time, and child support are generally subject to the court’s review based on the child’s best interests, so they are not something spouses can simply decide in advance. An experienced attorney can help you understand which terms are likely to hold up.
The right choice usually depends on where you are in your relationship and what has changed.
you are engaged and want to protect assets, a business, or an inheritance, or want clarity about debts and support before the marriage begins.
you are already married and have started a business, received an inheritance, experienced a major career or financial change, or want to put an understanding in writing that was never formalized.
you want to reduce uncertainty and prevent future conflict by setting expectations in writing.
Often, yes. Many business owners use prenuptial and postnuptial agreements to protect ownership interests and reduce future disputes involving the business. A well-drafted agreement can define the business as separate property and address how any increase in value during the marriage will be treated. This is especially valuable for businesses started or significantly grown after the wedding, where a postnuptial agreement may be the better fit.
For a prenuptial agreement, it is generally best to begin the process well before the wedding so both parties have enough time to review and negotiate. Signing too close to the ceremony can raise questions later about whether the agreement was signed voluntarily. For a postnuptial agreement, both spouses should have adequate time to review the terms and ideally consult their own attorneys before signing.
Talk through what matters most, whether it is asset protection, business interests, or clarity about the future.
Each party discloses assets, debts, and income so the agreement is based on accurate information.
An attorney prepares terms addressing property, debt, support, and your specific concerns.
Each party ideally has their own attorney review the agreement before signing.
Both parties sign without pressure or coercion, and with adequate time, which supports enforceability later.
Sometimes. Spouses can often modify or replace a prenuptial or postnuptial agreement if both parties agree and the changes comply with Tennessee law. Any changes should be carefully documented and reviewed by an attorney, just like the original agreement.
Prenuptial agreements often connect to other family law topics.
