South Carolina Prenuptial Agreement
South Carolina prenuptial agreements are governed by SC Code § 20-3-630 (defining nonmarital property and the presumption of fairness) and common-law enforceability standards. Courts apply a three-part test established in Hardee (2003): fraud/duress/nondisclosure at signing, unconscionability at signing, and changed circumstances at enforcement. There is no statutory alimony floor, but courts retain discretion to refuse enforcement if circumstances have changed enough to make the agreement unfair. One notable precedent in South Carolina's favor: Hardee upheld a complete alimony waiver even where the spouse became totally disabled during the marriage, finding disability was foreseeable at signing.
Bottom line: South Carolina earns a C+ grade. The changed-circumstances prong of the Hardee test and the absence of a comprehensive prenuptial agreement statute create enforcement uncertainty, but Hardee shows courts will hold firm on well-executed agreements even in sympathetic circumstances. A prenup is far better than none.

South Carolina Prenup Laws: Key Statutes Explained
South Carolina Prenuptial Agreement Law (§ 20-3-630 and Common Law)
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names are split 50/50 as marital property.
Unconscionability Dual Review
The Hardee three-part test evaluates a prenuptial agreement at two points in time: prongs 1 and 2 (fraud/duress, unconscionability) are assessed as of signing, while prong 3 (changed circumstances) is assessed at enforcement. This means courts can refuse to enforce an agreement that was valid when signed if circumstances have changed enough to make enforcement unfair and unreasonable.
Unconscionability Standard
Under the Hardee three-part test, a prenup is unenforceable if any one ground is met: (1) obtained through fraud, duress, mistake, misrepresentation, or nondisclosure of material facts; OR (2) unconscionable at execution — absence of meaningful choice combined with terms so oppressive no reasonable person would make them; OR (3) facts and circumstances have changed since execution, making enforcement unfair and unreasonable.
No Spousal Support Minimum Established
South Carolina has no statutory public-assistance floor for spousal support waivers. Alimony waivers are not per se unconscionable under Hardee. Courts can refuse enforcement under prong 3 if circumstances have changed enough to make the waiver unfair, but the bar is high — Hardee upheld a total alimony waiver despite the wife becoming totally disabled during the marriage.
Timing
No minimum specified, but we recommend signing the prenup 60+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing.
Independent Counsel Nearly Required
Under § 20-3-630, a prenup is only "presumptively fair and equitable" if both parties were separately represented by counsel. Without separate counsel the agreement isn't void, but it loses the statutory presumption and becomes far more vulnerable to challenge.
Financial Disclosure
"Full and fair" disclosure of all property, assets, debts, and income required. Complete South Carolina Family Court Financial Disclosure forms listing every asset and debt with corresponding values. For real estate, disclose fair market value AND mortgages. Include source documents (tax returns, statements, appraisals).
Moderate Burden to Challenge
The spouse challenging the prenup bears the burden of proof on all three Hardee prongs: fraud/duress/nondisclosure, unconscionability at execution, or changed circumstances making enforcement unfair.
Child Support and Custody
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
South Carolina Prenuptial Agreement Court Cases
Holler v. Holler, 364 S.C. 256, 612 S.E.2d 469 (Ct. App. 2005)
The Court of Appeals invalidated a prenuptial agreement as unconscionable and signed under duress where a Ukrainian wife with poor English was unable to understand the legal terms, could not afford a translator or attorney, was falsely told the agreement was required for marriage in South Carolina, and had an expiring visa that created pressure to sign.
Hardee v. Hardee, 355 S.C. 382, 585 S.E.2d 501 (2003)
The South Carolina Supreme Court established the three-part test for prenuptial agreement enforceability and held that agreements waiving alimony, support, and attorney's fees are not per se unconscionable, enforcing the alimony waiver despite the wife becoming totally disabled during the marriage because she had meaningful choice, received independent legal advice (though her attorney advised against signing), and the disability was foreseeable.
Hudson v. Hudson, 408 S.C. 76, 757 S.E.2d 727 (Ct. App. 2014)
The Court of Appeals upheld mutual waivers of alimony and property rights despite the wife using a non-practicing attorney selected by the husband who merely told her "Husband was a good guy" — finding she willingly accepted that counsel, knew of his failure to advise her, was psychologically capable, the mutual terms were not one-sided, and her financial circumstances at divorce were substantially the same as at signing.
Gilley v. Gilley, 327 S.C. 8, 488 S.E.2d 310 (1997)
The Supreme Court held that property excluded by a valid prenuptial agreement is nonmarital property outside the family court's jurisdiction, affirming dismissal of the husband's family court action for separate maintenance and equitable distribution where the prenuptial agreement precluded both parties from claiming alimony or equitable apportionment.
Bowen v. Bowen, 352 S.C. 494, 575 S.E.2d 553 (2003)
The South Carolina Supreme Court held that wife owned an undivided one-half interest in four properties husband had titled jointly with her during the marriage, rejecting his argument for a resulting trust — holding that the prenuptial agreement's plain language governed the parties' property rights and made the trust-presumption analysis unnecessary.
Heins v. Heins, 344 S.C. 146, 543 S.E.2d 224 (Ct. App. 2001)
The Court of Appeals addressed procedural issues regarding contempt proceedings and Rule 59(e) motions in the context of enforcing a prenuptial agreement involving a family business, establishing that family courts cannot sua sponte reverse their initial decisions without proper motion practice.
Meehan v. Meehan, 407 S.C. 471, 756 S.E.2d 398 (Ct. App. 2014)
The Court of Appeals determined that a prenuptial agreement stating "the Family Court shall not have jurisdiction over any pre-marital property" only partially limited family court jurisdiction, clarifying that parties cannot completely divest family courts of jurisdiction through prenuptial agreements but can designate property as nonmarital.
5-Step Checklist: How to Sign & Execute a Prenup in South Carolina
Step 1: Download and read the South Carolina prenuptial agreement
Start with our free template. It is written for South Carolina-specific statutes and case law under SC Code § 20-3-630 and the Hardee v. Hardee, 355 S.C. 382 (2003) three-part enforceability test. Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions. South Carolina has not adopted the UPAA — and uniquely, its statute makes separate legal representation on both sides a prerequisite for the agreement to be "presumptively fair and equitable."
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a lawyer in your state
Find a matrimonial or divorce attorney in your state. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 60+ days before the wedding. South Carolina practitioners recommend a minimum of 30 days before the wedding — last-minute presentation is a primary driver of duress findings, and Holler (2005) voided an agreement where compounding time pressure and language barriers eliminated meaningful choice.
Step 5: Sign with your attorneys and store the agreement
Execute the agreement with both attorneys present. Under § 20-3-630, the prenup is only presumptively fair and equitable if both parties were separately represented by counsel. Each party keeps a signed original, and so should each party's attorney. Store yours somewhere secure like a safety deposit box. Create a .pdf and save it via a backup drive and email.
South Carolina Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenuptial agreements enforceable in South Carolina?
Yes. South Carolina courts enforce prenuptial agreements under the three-part test from Hardee v. Hardee, 355 S.C. 382 (2003). The agreement must not have been obtained through fraud, duress, or nondisclosure; it must not be unconscionable at the time of execution; and circumstances must not have changed so drastically since signing that enforcement would be unfair and unreasonable. Under § 20-3-630, an agreement executed with both parties separately represented by counsel and full financial disclosure is "presumptively fair and equitable." Without that foundation, the agreement is still valid but loses the statutory presumption and faces heightened scrutiny.
2. How much does a prenup cost in South Carolina?
Attorney-drafted from scratch: $1,500–$5,000+ per side, depending on asset complexity. A more cost-effective approach: start with a South Carolina-specific template, draft changes with an AI like Claude, then hire an attorney to review and assist with signing — typically around $500 per side. Both parties need separate attorneys to trigger the § 20-3-630 presumption of fairness, so budget for two lawyers. Mediation-style approaches with a single attorney will not satisfy the separate-counsel requirement.
3. Do I need a lawyer to get a prenup in South Carolina?
Effectively yes — and both sides need their own. Under § 20-3-630, a prenup is only "presumptively fair and equitable" if both parties were separately represented by counsel and made full financial disclosure. Unlike UPAA states, South Carolina has no provision to formally waive independent counsel in writing. Without separate attorneys, the agreement isn't automatically void, but it loses its statutory presumption and becomes far more vulnerable to challenge. Use a template to reduce drafting costs, but don't skip the attorney.
4. What makes a prenup invalid in South Carolina?
Under the Hardee three-part test, any one ground is sufficient: (1) the agreement was obtained through fraud, duress, mistake, misrepresentation, or nondisclosure of material facts — Holler v. Holler (2005) voided a prenup where a Ukrainian wife with limited English was falsely told it was legally required for marriage; (2) the agreement was unconscionable at execution — no meaningful choice combined with terms so oppressive no reasonable person would make them; or (3) facts and circumstances have changed since signing, making enforcement unfair and unreasonable. Including child custody or support provisions can also jeopardize the entire agreement.
5. What are the legal requirements for a prenup in South Carolina?
South Carolina does not have a dedicated prenuptial agreement statute — it relies on § 20-3-630 and case law rather than the Uniform Premarital Agreement Act. For the strongest enforceability: the agreement must be in writing and signed by both parties; both parties must be separately represented by counsel; both must make full financial disclosure of income, assets, and debts per family court rules; the agreement must be entered voluntarily without duress; and the terms must not be unconscionable. The separate-counsel and full-disclosure requirements are what trigger the § 20-3-630 presumption of fairness — miss either one and the agreement starts at a disadvantage.
6. Can you waive alimony in a prenuptial agreement in South Carolina?
Yes. The South Carolina Supreme Court held in Hardee v. Hardee (2003) that prenuptial provisions waiving alimony, spousal support, and attorney's fees are not per se unconscionable and do not violate public policy — explicitly overruling the older Towles v. Towles (1971) decision. Hardee enforced a total alimony waiver even where the wife became totally disabled during the marriage, finding the disability was foreseeable at signing. There is no statutory public-assistance floor. However, courts retain discretion under prong 3 of the Hardee test to refuse enforcement if circumstances have changed drastically enough to make the waiver unfair and unreasonable. The waiver must be knowing, voluntary, and made with full financial disclosure.
7. How far in advance should I sign a prenup in South Carolina?
There is no statutory minimum, but timing matters. Sign at least 60 days before the wedding, and give your spouse a minimum of two weeks to review the final version with their own attorney. South Carolina practitioners recommend 30 days as an absolute floor — Holler v. Holler (2005) voided an agreement where last-minute presentation was one of several compounding duress factors. Contact an attorney 4–6 months before the wedding with your draft. Best practice: sign before proposing. No time pressure, no duress argument, and you'll know this is the right person to marry.
8. Can a prenup protect my business in South Carolina?
Yes, and this is one of the strongest reasons to get one. Without a prenup, business appreciation during the marriage may be classified as marital property subject to equitable distribution under § 20-3-620 — even if you founded the company before the marriage. A prenup can classify the business as separate property, define how appreciation and income are treated, and prevent your spouse from claiming an equitable share of goodwill. If your spouse contributes labor to the business during the marriage, address that explicitly — Hudson v. Hudson (2014) upheld a mutual waiver even where the wife helped in the husband's lifeguard business for 8½ years.
9. Is South Carolina a community property or equitable distribution state?
South Carolina is an equitable distribution state under § 20-3-620. Courts divide marital property based on what they consider fair — weighing 15 statutory factors including each spouse's contributions, the marriage's duration, and earning capacity — not automatically 50/50. "Equitable" doesn't mean "equal," and a judge's idea of fair may not match yours. A valid prenup with separate counsel and full disclosure overrides this discretionary framework under § 20-3-630, letting you and your spouse decide in advance how property is handled rather than leaving it to a judge.
10. Can I get a postnuptial agreement in South Carolina?
Yes, but postnuptial agreements face greater judicial scrutiny than prenups because spouses owe each other fiduciary duties during the marriage. Full financial disclosure, independent counsel, and voluntary execution are even more critical. A pending bill in the South Carolina legislature (H. 4800, 2025–2026 session) would, if enacted, create a statutory framework allowing family courts to pre-approve both prenuptial and postnuptial agreements, establishing a rebuttable presumption of validity. That bill has not passed as of this writing. Under current law, postnuptial agreements are evaluated under the same Hardee common-law framework as prenups.
11. Can a prenup be thrown out in South Carolina?
Yes. A court can refuse to enforce a prenup under any of the three Hardee prongs: fraud, duress, or nondisclosure at signing; unconscionability at signing; or changed circumstances at enforcement. Common fact patterns that lead to invalidation: one party lacked independent counsel, financial disclosure was incomplete, the agreement was presented too close to the wedding, or one party couldn't understand the terms due to language barriers (Holler, 2005). The single most important safeguard is separate counsel on both sides — without it, the agreement loses its § 20-3-630 presumption and becomes significantly easier to attack.
12. Does South Carolina follow the Uniform Premarital Agreement Act?
No. South Carolina has never adopted the UPAA. A bill to enact it (H. 3203) was introduced in 1991 but died in the House in 1992. South Carolina prenups are governed by a single subsection of a property statute — § 20-3-630(A)(4), which defines the conditions for the presumption of fairness — plus common-law standards from Hardee v. Hardee (2003) and its progeny. This means SC lacks many UPAA features: there is no written waiver-of-counsel provision, no codified list of permissible prenup subjects, and no statutory public-assistance floor for alimony waivers. A new bill (H. 4800, 2025–2026 session) would create a broader statutory framework, but it has not passed.
13. Can a prenup in South Carolina address inheritance and estate planning?
Yes. A prenup can waive or modify each spouse's rights to the other's estate, including the elective share (the statutory right to claim a portion of a deceased spouse's estate regardless of the will). This is especially important for blended families where one or both spouses want to preserve assets for children from a prior marriage. The prenup can also address life insurance beneficiary designations and the treatment of inheritances received during the marriage. Under § 20-3-630, inherited property is already classified as nonmarital, but commingling it with marital funds can "transmute" it into marital property — a well-drafted prenup prevents that.
14. Can a South Carolina prenup include an infidelity clause?
South Carolina courts have not directly ruled on the enforceability of infidelity clauses in prenuptial agreements. Adultery is one of the statutory grounds for fault-based divorce under § 20-3-10 and is a factor courts consider in alimony decisions under § 20-3-130. A prenup could tie alimony or property terms to marital misconduct, but any such clause risks being deemed unconscionable if it produces a wildly disproportionate result. Courts are far more likely to enforce financial provisions — property division, alimony formulas, debt allocation — than lifestyle or behavioral clauses. If you include an infidelity provision, keep the financial consequences proportionate and make sure the rest of the agreement stands independently if the clause is severed.
