Bringing up a prenuptial agreement with your future spouse can feel awkward, like you’re planning for the marriage to fail before it even starts. In reality, a prenup is just a financial planning tool, one that can actually make a marriage stronger by getting money conversations out in the open early. This guide covers what a prenup actually is, what it can and can’t do, and how Tennessee law treats these agreements.
This guide is part of our broader guide to family law in Tennessee, so if you want the wider picture of how a prenup fits alongside marriage and divorce generally, that’s a good place to start.

A prenuptial agreement, sometimes called a premarital or antenuptial agreement, is a written contract two people sign before they get married, spelling out how they want financial matters handled during the marriage and, especially, if it ever ends in divorce or death. Instead of leaving those questions entirely up to state law later, a prenup lets a couple decide many of these terms for themselves, in advance, while they’re on good terms and thinking clearly about the future.
Prenups are recognized across the United States, though the specific rules for what makes one valid and enforceable vary by state. Many states, including Tennessee, base their approach on principles similar to the Uniform Premarital Agreement Act, a model law designed to bring some consistency to how these agreements are treated from state to state, though each state has adapted it somewhat differently.
A well-drafted prenup can address a wide range of financial matters, including:
Defining upfront what each spouse brought into the marriage and what will be considered jointly owned.
If the marriage ends in divorce.
Including whether it would be paid, how much, or whether it’s waived entirely.
Keeping a business interest classified as separate property and out of a future division.
Making sure money or property meant to stay in one person’s family stays there.
So one spouse isn’t unexpectedly responsible for the other’s premarital debt.
In some cases, setting ground rules for transparency between spouses.
Making sure the prenup lines up with wills, trusts, and beneficiary designations rather than contradicting them.
Prenups are powerful, but they’re not unlimited. There are some things they generally can’t control.
Custody decisions have to be based on the child’s best interests at the time of a divorce, not on an agreement signed years earlier before the child even existed.
Parents can’t sign away a child’s right to financial support in advance, and courts will still apply child support guidelines regardless of what a prenup says.
Provisions that violate the law, or that seem specifically designed to financially reward getting divorced, are generally not enforceable.
Clauses about things like household chores or how often you spend time with in-laws are generally not the kind of thing courts will enforce.
Even financial terms that would otherwise be allowed can be thrown out if the agreement itself wasn’t entered into properly.
Tennessee law addresses premarital agreements directly under Tenn. Code Ann. § 36-3-501, and for one to hold up, it generally needs to meet several requirements.
Tennessee doesn’t recognize oral prenuptial agreements.
An agreement signed under pressure, coercion, or duress is vulnerable to being thrown out later.
Each spouse should have a genuine, accurate picture of the other’s assets, debts, and income before signing, unless that disclosure is knowingly and explicitly waived.
Courts look at whether the terms were so one-sided or unfair, given what was known at signing, that enforcing them wouldn’t be right.
Because these requirements involve both the process (how it was signed) and the substance (whether it was fair), a prenup that skips a legal formality or was clearly one-sided can end up unenforceable exactly when a couple needs it most.
Written and properly signed, meeting Tennessee’s basic formal requirements.
Full financial disclosure, or explicitly and knowingly waiving that disclosure.
No signs of duress or coercion, meaning neither party felt pressured or rushed into signing.
Fair terms at the time of signing, since a wildly one-sided agreement invites a stronger legal challenge later.
Enough time before the wedding, since signing days or hours before the ceremony is one of the most common ways these agreements get successfully challenged.
Independent legal counsel for each party, which significantly strengthens an agreement’s enforceability.
Here’s roughly what putting together a prenup looks like, step by step.
Waiting until right before the wedding creates unnecessary pressure and legal risk, start months in advance if you can.
Both partners should lay out their complete financial picture, assets, debts, income, and anything else relevant.
Having separate representation protects both people and makes the agreement much harder to challenge later.
This is where you work through what you both actually want the agreement to cover.
Your attorneys put the negotiated terms into a legally sound written document.
Both sides should have a genuine opportunity to review, ask questions, and request changes.
Finalizing the agreement well before the ceremony helps avoid any later claim that someone was pressured or rushed.
Keep the original somewhere secure, and make sure both spouses know where to find a copy if it’s ever needed.
A postnuptial agreement works in much the same way as a prenup, but it’s signed after the wedding instead of before. Couples use postnups for a lot of the same reasons: protecting a business, clarifying how property will be handled, or simply getting on the same page financially, sometimes prompted by a major life change like starting a business, receiving an inheritance, or working through a rough patch in the marriage. The legal requirements are similar to a prenup, in writing, signed voluntarily, with full disclosure and fair terms, just without the built-in timing pressure of an approaching wedding.
Entering a second marriage, especially when there are children from a previous relationship.
Owning or co-owning a business, to keep it protected and out of a future divorce.
A significant difference in income or wealth between partners.
Protecting an inheritance or family assets, keeping them separate from the marriage.
Clarifying responsibility for existing debt, so one spouse doesn’t take on the other’s premarital obligations.
Wanting a clearer, faster process if the marriage were ever to end.
Coordinating with an existing estate plan, especially for people who already have significant assets or a trust in place.
Beyond protecting specific assets, a well-drafted prenup can genuinely benefit a marriage in ways couples don’t always expect going in.
Both spouses start the marriage knowing exactly where they stand financially, rather than leaving major questions unresolved.
The disclosure process forces an honest, complete conversation about money that a lot of couples otherwise put off for years.
A business, an inheritance, savings, or property you owned beforehand stays clearly defined as yours.
Each spouse knows upfront what they are, and aren’t, taking on responsibility for.
Working through a prenup together, especially with separate attorneys involved, tends to build trust rather than damage it.
With the big financial questions already answered, a divorce is far less likely to turn into a prolonged, expensive fight.
A prenup can be built to work seamlessly with a will or trust, rather than leaving gaps or contradictions between the two.
And often for their families too, especially in situations involving a family business, a blended family, or a significant difference in wealth.
Yes, and it happens more often than people expect, usually because of a problem with how the agreement was created, not just because someone doesn’t like the outcome. Common grounds for challenging a prenup include:
It wasn’t in writing or properly signed.
One party was pressured, coerced, or didn’t have a real chance to review it, especially if presented right before the wedding.
There wasn’t full and fair financial disclosure, and it wasn’t clearly and knowingly waived.
The terms were unconscionable at the time of signing.
One party lacked the mental capacity to understand what they were signing.
There was fraud, such as one party lying about their assets or debts.
This is exactly why the process of creating a prenup matters as much as what it actually says, a legally sound agreement, created the right way, is far more likely to hold up when it’s actually needed.
Even when a prenup isn’t successfully thrown out in court, plenty of them still cause problems down the road because of avoidable mistakes made along the way.
Bringing up the agreement just weeks, or days, before the wedding creates real legal risk and unnecessary stress.
A single attorney can’t fully represent both sides’ interests, making the agreement much easier to challenge later.
Leaving out assets or debts, even unintentionally, can undermine the entire agreement.
An agreement that clearly favors one spouse invites a much stronger unconscionability challenge down the road.
Terms that seemed clear to both of you when you signed can turn into a genuine dispute years later.
A lot of prenups focus entirely on what happens if the marriage ends, while ignoring what happens if a spouse dies.
A prenup signed early in a marriage may no longer reflect reality years later.
Some prenups say very little about how jointly acquired property and income will be handled.
A prenup negotiated in anger, guilt, or as a rushed compromise often ends up poorly thought through.
Most of these pitfalls are entirely avoidable with enough lead time and the right guidance, which is a big part of why starting the process early, and working with an attorney rather than a generic template, matters so much.
Prenuptial agreements often connect to other family law topics.
A prenup is only as strong as how it was created. At Dahl Family Law, we bring:
A clear understanding of Tennessee’s requirements for a valid, enforceable premarital agreement.
Careful attention to full financial disclosure, so your agreement doesn’t get challenged later over what wasn’t shared.
Thoughtful drafting that protects what matters to you without souring the process leading up to your wedding.
Coordination with your broader estate plan, so everything works together.
It's not strictly required, but it's strongly recommended. Having separate attorneys helps show the agreement was genuinely voluntary and fair to both sides, which makes it much harder to successfully challenge later.
Yes. Couples can amend an existing prenup, or create a postnuptial agreement, at any point during the marriage, as long as both spouses agree and the same basic legal requirements are met.
Not at all. While prenups are common in situations involving significant assets or a business, plenty of couples use them simply to clarify debt responsibility, protect a modest inheritance, or get on the same page financially before the marriage starts.
No. Most couples find that working through a prenup together actually improves communication about money, rather than damaging trust. It's a practical planning tool, not a prediction about how the marriage will go.
Whether you’re getting married for the first time or bringing more complexity into a second marriage, a well-drafted prenup gives you clarity and protection going into your new chapter.
