Prenuptial Agreements in South Carolina: Rules, Enforceability, and What One Costs

Congratulations on planning your marriage. If you are reading this, you are already doing the thoughtful part: figuring out how the law works before you sign anything. South Carolina couples marry and stay married at high rates. The state posted one of the lowest refined divorce rates in the country in 2024, at 11.7 divorces per 1,000 married women, according to the National Center for Family & Marriage Research at Bowling Green State University. Planning ahead is not a sign you expect the worst. It is how couples get on the same page about money, goals, and what belongs to whom.

A prenuptial agreement (commonly shortened to prenup) is a written contract that spells out how you and your partner will handle property, debt, and support if the marriage ends. In South Carolina, the rules for making one hold up have a specific shape, and a lot of what you will read online about this state is wrong. Let's walk through what the law says, what courts look for, and what it costs.

Are prenups legal in South Carolina?

Yes. South Carolina recognizes prenuptial agreements under S.C. Code § 20-3-630, which excludes from marital property any property covered by a written contract of the parties. In plain terms, the statute lets a couple use a written agreement to decide in advance that certain property stays outside the marital pot.

Here is a common error worth correcting. Several ranking pages claim South Carolina adopted the Uniform Premarital Agreement Act (often citing a 2009 effective date). It did not. South Carolina is one of the states that recognizes prenups through its own statute and case law rather than the uniform act. That difference matters because it means South Carolina courts lean on their own precedent to decide enforceability, not on the uniform framework other states share. For a broader picture of how states diverge on this, see our guide to how prenuptial agreements vary across America.

The practical takeaway: a prenup is a recognized, enforceable tool in South Carolina when it is done right. What "done right" means is the next question.

What makes a prenup enforceable in South Carolina?

Because South Carolina judges enforceability case by case, proper formation and full financial disclosure matter more than any single formality. The core building blocks are the ones you would expect: the agreement should be in writing, signed voluntarily by both partners, and backed by honest, complete disclosure of what each person owns and owes.

When a prenup is challenged, South Carolina courts apply a three-part test from Hardee v. Hardee, 355 S.C. 382, 585 S.E.2d 501 (2003). You can think of it as three questions a judge asks:

None of these is a box to check once and forget. They describe how a court views the agreement as a whole, from the way it was signed to how it plays out years later. That is why disclosure and voluntariness are worth getting right at the start. For a general checklist of what strengthens an agreement, our post on what makes a prenup enforceable covers the fundamentals that apply across states.

Because enforceability is decided case by case, no prenup can promise a guaranteed result. A well-formed, disclosure-backed agreement is designed to give a court every reason to uphold it.

Do you need two lawyers for a prenup in South Carolina?

Short answer: no. Independent counsel is not required for a prenup to be valid in South Carolina. You and your partner can have a valid agreement without each hiring your own attorney.

That said, separate representation does something specific under the statute. When both partners are separately represented and each has fully disclosed their finances, S.C. Code § 20-3-630 treats the agreement as presumptively fair and equitable. That presumption can strengthen the agreement if it is ever challenged, because it shifts the starting point in a court's analysis. So independent counsel is not a validity requirement; it is a factor that carries real weight.

For many couples with straightforward finances, a written agreement with genuine disclosure is enough. For couples with complex estates, business interests, or where the terms are heavily weighted toward one side, separate attorneys are worth considering. Our explainer on why two separate attorneys can matter walks through when that extra step pays off. If your situation calls for a lawyer's involvement, retaining your own South Carolina attorney is the route; First's guided process is built for couples who do not need that step.

How does South Carolina divide property without a prenup?

If you do not sign a prenup, South Carolina's default rules decide these questions for you. The state follows equitable distribution, the rule that a court divides marital property in a way it considers fair, which is not necessarily an equal 50/50 split. That last part surprises people, and "equitable" doesn't always mean "equal." A judge weighs factors like the length of the marriage, each partner's contributions, and economic circumstances, then arrives at a division the court considers fair.

Marital property generally means what you built during the marriage. Property covered by a written contract of the parties is excluded, which is where a prenup does its work. Inheritances and third-party gifts to one spouse are generally treated as separate property, though how they are handled can get complicated if they get mixed with marital assets.

Without an agreement, all of these calls belong to a family court judge who does not know you. A prenup lets you and your partner make them yourselves, in advance, with full information. If you want to see what the default looks like in practice, our post on what happens if you don't have a prenup breaks down how default state rules shape a divorce.

How much does a prenup cost in South Carolina?

Cost is where most couples land before deciding, so let's be concrete. The attorney route depends heavily on hourly rates. South Carolina family-law attorneys generally charge in the range of $200 to $400 per hour; the Bureau of Labor Statistics tracks wage data for lawyers in the state as a baseline. With two attorneys negotiating a full agreement, costs commonly reach the low thousands per person. A guided online prenup costs far less.

Here is how the common paths compare:

That last row deserves a warning. A blank prenup template with no disclosure prompts and no state-law logic is the cheapest option upfront and the riskiest at the point it matters. In a state where enforceability turns on disclosure and formation, a form that skips both leaves you exposed. For a national breakdown of price ranges, see our guide to how much a prenup costs.

This is where First's process is built to help. No PDFs, no hourly clock, no back and forth with attorneys unless you want it. You and your partner walk through a structured, South Carolina-aware questionnaire that prompts the disclosures the law cares about, and you can add independent attorney review if your situation calls for it.

Frequently asked questions

Are prenuptial agreements enforceable in South Carolina?

Yes. South Carolina recognizes prenups under S.C. Code § 20-3-630 and through case law. To be enforced, an agreement generally must be in writing, signed voluntarily, and backed by full financial disclosure. Courts then apply the Hardee v. Hardee three-part test to decide whether to uphold it.

Do both people need their own lawyer for a prenup in South Carolina?

No, separate lawyers are not required for a prenup to be valid in South Carolina. However, when both parties are separately represented and fully disclose their finances, the agreement is treated as presumptively fair under S.C. Code § 20-3-630, which can strengthen enforceability.

How much does a prenup cost in South Carolina?

Costs vary. South Carolina family-law attorneys generally charge $200 to $400 per hour, so an attorney-drafted prenup often reaches the low thousands per person. A guided online prenup typically costs several hundred dollars total, depending on complexity and whether attorney review is added.

Does a prenup have to be notarized in South Carolina?

Notarization is not strictly required for validity in South Carolina, but it is widely recommended. A notary confirms identity and that both parties signed, which creates a cleaner evidentiary record if the agreement is ever challenged in family court.

What happens if you divorce in South Carolina without a prenup?

South Carolina is an equitable-distribution state, so a family court divides marital property in a way it considers fair, which is not always a 50/50 split. Inheritances and third-party gifts are generally separate. A prenup lets you set these terms yourselves instead.
