A prenuptial agreement is a written contract two people sign before marriage to decide how property, debt, and financial support will be handled if the marriage ends. In South Carolina the document is sometimes called a premarital or antenuptial agreement.
Not legal advice. This article is general information only. Prenup laws differ by state and change over time. Consult a licensed attorney in your state before acting on anything here.
South Carolina treats these contracts seriously, but it judges them differently from many other states. The state has not adopted the Uniform Premarital Agreement Act, so the rules come from court decisions rather than a single statute.
This guide explains how South Carolina courts decide whether a prenup holds up, what the agreement can and cannot do, and how couples create one that is likely to be enforced.
Are Prenups Valid in South Carolina?
Yes. South Carolina enforces prenuptial agreements that are entered fairly and that meet the standards set by the state’s appellate courts. Because there is no statewide premarital agreement statute, the controlling rules come from case law.
The leading decision is Hardee v. Hardee, decided by the South Carolina Supreme Court in 2003. A later Court of Appeals case, Holler v. Holler, shows what happens when these standards are not met.
The Hardee Enforceability Test
In Hardee, the court applied a three-part test for deciding whether a premarital agreement should be enforced. A court reviews the agreement under each of these questions.
First, was the agreement obtained through fraud, duress, mistake, or the misrepresentation or nondisclosure of material facts? An agreement signed under pressure or based on hidden assets can be set aside.
Second, is the agreement unconscionable? Terms so one-sided that no reasonable person would have agreed to them can fail this part of the test.
Third, have the facts and circumstances changed so much since signing that enforcement would now be unfair and unreasonable? This question looks at the situation at the time of divorce, not only at the time of signing.
Who Bears the Burden of Proof
The spouse who wants to escape the agreement is the one who must prove it is invalid. That person has to show fraud, duress, a lack of disclosure, unconscionability, or a major change in circumstances.
The Holler case illustrates a successful challenge. There, a spouse with limited English signed shortly before her visa expired, after being told the document was required to marry and that she would face deportation if she refused. The family court found duress and an unconscionable agreement, and the result was not enforced.
What Belongs in a South Carolina Prenup
A prenup can settle most financial questions a couple may face. The table below lists common subjects South Carolina allows.
| Topic | What the Agreement Can Do |
|---|---|
| Separate property | Identify assets each person keeps as their own and outside division |
| Marital property | Define how property acquired during the marriage will be divided |
| Debts | Limit one spouse’s liability for the other’s debts |
| Spousal support | Set, limit, or waive alimony, subject to court review |
| Inheritance and gifts | Protect assets meant for children from a prior relationship |
| Business interests | Keep a company or professional practice with its original owner |
| Financial roles | Spell out how accounts, income, and expenses are handled |
What a South Carolina Prenup Cannot Do
Some terms are off limits no matter how the agreement is written. A court will ignore or strike provisions that cross these lines.
- Set or waive child support, which belongs to the child and is decided by the court
- Decide child custody or visitation, which is judged by the best interests of the child at the time of divorce
- Require anything illegal or against public policy
- Include terms that encourage or reward divorce
- Permanently bind a court on alimony, since South Carolina courts keep the power to review a support waiver for fairness
Signing a South Carolina Prenup the Right Way
South Carolina does not impose a long checklist by statute, but its courts expect certain practices. Following them makes an agreement far harder to challenge.
Writing and Signatures
The agreement must be in writing and signed by both people before the wedding. An oral promise about property or support is not a valid prenup.
Notarization is not strictly required, but it is standard practice in South Carolina. A notarized signature helps confirm that each person signed and reduces later disputes.
Time and Independent Counsel
Courts look closely at how much time passed between signing and the wedding. Signing well in advance, rather than days before the ceremony, weakens any later claim of pressure.
Each person should have a chance to review the agreement and consult a separate attorney. When both spouses have their own lawyers, a court is much more likely to treat the agreement as fair and voluntary.
Alimony in a South Carolina Prenup
South Carolina allows couples to address alimony in a prenup, including waiving it entirely. The state’s courts have held that an alimony waiver is not automatically unconscionable or against public policy.
That said, a support waiver is not free from review. A court can examine the waiver under the Hardee test and decline to enforce it if circumstances have changed enough to make the result unfair and unreasonable.
Because of this, an alimony waiver works best when both spouses had full information, their own counsel, and adequate time to decide. Those facts make a waiver much more likely to survive a challenge.
Full Financial Disclosure
Honest disclosure is one of the strongest factors in whether a South Carolina prenup is enforced. The Hardee test treats nondisclosure of material facts as a reason to set an agreement aside.
Each person should share a complete account of income, assets, and debts, with values attached. Many couples exchange written financial statements and attach them to the agreement as proof.
Hiding an account, undervaluing a business, or leaving out a debt gives the other spouse grounds to attack the contract later. Full disclosure protects both people and the agreement itself.
South Carolina Law When There Is No Prenup
Without a prenup, South Carolina divides property under its equitable distribution rules, often called equitable apportionment. The governing statute is South Carolina Code Section 20-3-620.
Equitable does not mean equal. A family court looks at factors such as the length of the marriage, each spouse’s contributions including work as a homemaker, income and earning potential, health, and the economic effect of any marital misconduct.
The court applies those factors to decide a fair split of marital property and may also rule on alimony. A valid prenup lets a couple set their own terms instead of leaving these outcomes to a judge.
Common Reasons South Carolina Prenups Fail
Most invalid prenups share a few avoidable problems. Watching for these reduces the risk of a court refusing to enforce the agreement.
- Signing under pressure or close to the wedding date, supporting a claim of duress
- Hiding or understating assets, income, or debts
- Terms so one-sided that a court finds them unconscionable
- Denying one spouse a real chance to read the agreement or hire counsel
- Trying to control child support or custody, which courts will not allow
- A major change in circumstances that makes enforcement unfair years later
South Carolina Prenup Costs Explained
The cost depends on how complex the finances are and whether each person hires an attorney. The table below shows typical ranges in South Carolina.
| Option | Typical Cost |
|---|---|
| Attorney drafted, simple estate | $1,500 to $5,000 per couple |
| Attorney drafted, complex estate | $2,000 to $7,000 per person |
| Online prenup platform | A few hundred dollars, flat rate |
Online services such as HelloPrenup let couples prepare an agreement at a flat price, which can be far cheaper than full attorney drafting. Many couples use an online platform to build a draft and then have an attorney review it before signing.
How to Set Up Your South Carolina Prenup
A clear process helps produce an agreement that is fair and likely to be enforced. The steps below follow the practices South Carolina courts reward.
- Start early, ideally months before the wedding, so neither person feels rushed
- Talk openly about goals for property, debt, and support
- Exchange full written disclosure of income, assets, and debts
- Draft the agreement using an attorney or a trusted online platform
- Have each person review it with separate legal counsel
- Sign the written agreement, with notarization, before the ceremony
- Store signed copies somewhere safe and accessible
Final Thoughts on a South Carolina Prenup
A South Carolina prenup can give a couple control over their finances and reduce conflict if the marriage ends. Because the state relies on case law rather than the UPAA, fairness, disclosure, and voluntary signing carry real weight.
An agreement that meets the Hardee standards, with full disclosure and time for each person to get advice, has the best chance of holding up. Careful preparation now protects both spouses later.
