Why a South Carolina prenup is different
A First prenup is built around the laws of South Carolina, and you, from the ground up.
The code recognizes prenups, and case law sets the test
South Carolina's divorce code treats property excluded by a written contract, a prenup included, as separate rather than marital. What the state never adopted is the Uniform Premarital Agreement Act, so a challenged agreement is judged under the South Carolina Supreme Court's decision in Hardee v. Hardee: free of fraud, duress and nondisclosure, not unconscionable, and still fair to enforce when the day comes.
South Carolina does not require you each to hire a lawyer
No South Carolina statute requires a prenup to be reviewed by attorneys, notarized, or witnessed. Courts do weigh whether each partner had a real chance to understand what they were signing, which is why disclosure and timing matter more than paperwork. Complete, honest disclosure from both partners, signed well before the wedding, is what the Hardee test rewards.
Equitable distribution is the default you are replacing
Without a prenup, a South Carolina family court apportions marital property equitably, weighing the length of the marriage, each spouse's contributions including as a homemaker, and a list of other statutory factors. Equitable means fair in context, not equal, and it is decided by a judge who does not know either of you. A prenup is how you two decide instead.

First vs hiring two South Carolina attorneys on your own
Key considerations
A South Carolina prenup is $649 flat for the couple through First, completed online with notarization included. Hiring two attorneys separately in South Carolina, where family law attorneys bill $200 to $500 an hour and Charleston, Columbia and Greenville run $350 to $500, commonly lands between $3,700 and $12,400 for the couple.
Hired separately, a prenup is quoted per partner and often billed hourly, so the final number is hard to predict before you start. First is one flat price for both of you, with no retainer and no hourly bills.
The fees also price only the legal work. Hiring on your own means building a shortlist of South Carolina family law attorneys, calling each one, booking consults, and confirming both fees and availability against your wedding date, then running all of it again because your partner needs a different attorney. First replaces this work with a process the two of you complete together, at your own pace, from anywhere in the state.

South Carolina prenup questions, answered
Is a prenup enforceable in South Carolina?
Yes. South Carolina's divorce code recognizes prenups directly: property excluded by a written contract, which the statute says includes an antenuptial agreement, is not marital property. South Carolina did not adopt the Uniform Premarital Agreement Act, so the test a challenged agreement has to pass comes from case law, principally the South Carolina Supreme Court decision in Hardee v. Hardee. A court asks three questions: was the agreement obtained through fraud, duress, mistake, or the misrepresentation or nondisclosure of material facts; is the agreement unconscionable; and have the facts and circumstances changed since it was signed so as to make enforcement unfair and unreasonable. An agreement built on full disclosure and signed voluntarily, with time to spare, is built to pass all three.
How much does a prenup cost in South Carolina?
With First, a South Carolina prenup is $649 flat for the couple, with online notarization included. Hiring attorneys instead commonly runs $3,700 to $12,400 for the couple, billed hourly at Charleston, Columbia and Greenville rates of $350 to $500 an hour, since each partner needs their own attorney and the hourly math runs twice. Our guide to what a prenup costs walks through that math.
Do you do prenups in Charleston, Columbia and Greenville?
Yes. First serves couples across South Carolina, including Charleston and Mount Pleasant, Columbia and the Richland and Lexington county suburbs, Greenville and Spartanburg, Rock Hill, and the Myrtle Beach and Hilton Head areas. Self-Serve is $649 flat for the couple and is completed online, so where in the state you live does not change the process or the price.
How much does a prenup cost in Charleston?
Charleston, Columbia and Greenville family law attorneys bill $350 to $500 an hour. Because each partner needs their own, hiring two separately commonly runs $3,700 to $12,400 for the couple. First is $649 flat for the couple, with online notarization included.
Do both people need a lawyer for a prenup in South Carolina?
No. No South Carolina statute requires either partner to be represented by an attorney for a prenup to be valid. South Carolina courts do treat independent counsel as one factor when weighing whether a partner signed voluntarily and understood the agreement, alongside financial disclosure and how much time each partner had to review it. Those last two are within your control, and they are what First Self-Serve is built around.
Can I do a South Carolina prenup online?
Yes. Nothing in South Carolina law treats an agreement differently because of how it was produced. What matters is that both partners disclosed their finances fully, both signed voluntarily, the terms are not unconscionable, and the agreement was drafted to South Carolina law. First Self-Serve is $649 for the couple and includes online notarization.
Does a South Carolina prenup have to be notarized?
South Carolina does not require a prenup to be notarized or witnessed for it to be valid. Notarizing it is still worth doing, because a notarized signature is straightforward evidence that both partners signed. First includes online notarization at no extra cost.
When should we sign a prenup in South Carolina?
As early as you reasonably can. South Carolina has no statutory waiting period, but timing is one of the clearest signals a court reads when someone argues they signed under duress. An agreement produced days before the ceremony, to a partner who has not seen it, is the fact pattern most likely to be challenged. Signing months ahead, after both partners have read it and had a real chance to ask questions, removes that argument.
Is First Self-Serve right for a complex South Carolina prenup?
Yes. Self-Serve covers business ownership, stock, options and RSUs, real estate, inheritance and gifts, existing child support or alimony obligations, and alimony terms, all for $649 flat for the couple. If you'd like to talk your situation through first, book a free 20-minute call.
What does a South Carolina prenup cover?
A South Carolina prenup can set out what counts as marital and separate property, how property and debts are divided if the marriage ends, what happens to a home, retirement accounts, inheritances and gifts, and whether alimony is modified or waived. It cannot decide child support or custody, which a South Carolina family court determines on the best interests of the child at the time the question arises.
