Frequently Asked Questions
Are prenuptial agreements enforceable in South Carolina?
Yes. South Carolina courts enforce prenuptial agreements as long as they meet specific requirements: both parties made full financial disclosure, both had independent legal counsel (or knowingly waived it), the agreement was signed voluntarily without duress, and the terms are not unconscionable at the time of enforcement.
How much does a prenuptial agreement cost in South Carolina?
The cost varies depending on the complexity of your financial situation. Simple prenups may cost between $1,500 and $3,000, while more complex agreements involving businesses, significant assets, or blended families may cost $3,000 to $7,500 or more. Contact Warner Law for a consultation to get a clearer estimate based on your needs.
Can you get a prenup after marriage in South Carolina?
You cannot get a prenuptial agreement after marriage, but you can enter into a postnuptial agreement. Postnuptial agreements serve a similar purpose and address many of the same issues but are executed after the wedding and may face slightly higher scrutiny.
What can a prenup NOT include in South Carolina?
A prenup cannot include provisions about child custody or child support, terms that encourage divorce, anything illegal, or provisions that are unconscionable or fundamentally unfair to one party.
Does South Carolina follow the Uniform Premarital Agreement Act?
South Carolina has not formally adopted the UPAA. However, SC courts apply similar principles when evaluating prenuptial agreements, focusing on voluntariness, full financial disclosure, and whether the terms are conscionable.
How far in advance should you sign a prenup before the wedding in SC?
We recommend signing at least 30 to 60 days before the wedding. Signing too close to the wedding date increases the risk that a court could find the agreement was signed under duress or pressure.
Can a prenuptial agreement be changed after marriage?
Yes. A prenuptial agreement can be amended or revoked after marriage, but only if both spouses agree in writing. Some couples update their prenup by executing a postnuptial agreement that reflects changed circumstances.
Do both parties need their own lawyer for a prenup in South Carolina?
South Carolina law does not strictly require both parties to have separate attorneys, but it is strongly recommended. If one party lacked independent legal counsel, a court may question whether the agreement was truly voluntary.
Prenuptial and Postnuptial Agreements in South Carolina: A Complete Guide
Planning a marriage is one of the most exciting times of your life. But alongside picking venues and choosing caterers, there’s a conversation many couples in Columbia, SC, and throughout South Carolina find equally important: protecting your financial future with a prenuptial agreement.
If the word “prenup” makes you uneasy, you’re not alone. Many people associate premarital agreements with distrust or pessimism. The reality is far different. A well-crafted prenuptial agreement is a practical financial planning tool—one that gives both partners clarity, security, and a voice in how their assets are handled, no matter what the future holds.
At Warner Law, we help couples and individuals across the Columbia, Richland County, and Lexington County areas draft prenuptial and postnuptial agreements that stand up in court and reflect the values of both parties. This comprehensive guide walks you through everything you need to know.
What Is a Prenuptial Agreement in South Carolina?
A prenuptial agreement (also called a premarital agreement or “prenup”) is a legally binding contract entered into by two people before they get married. The agreement outlines how specific financial matters—property, debts, spousal support, and more—will be handled during the marriage and in the event of divorce or death.
In South Carolina, prenuptial agreements are governed by common law principles and case law rather than the Uniform Premarital Agreement Act (UPAA), which the state has not formally adopted. However, SC courts apply similar standards, evaluating whether the agreement was entered into voluntarily, with full financial disclosure, and on conscionable terms.
Key Takeaway: A prenuptial agreement is not a plan for divorce—it’s a plan for your financial life together. It can protect both partners equally.
What Is a Postnuptial Agreement?
A postnuptial agreement is essentially the same type of contract, but it is executed after the couple is already married. If you didn’t get a prenup before the wedding—or if your circumstances have changed significantly since then—a postnuptial agreement allows you to establish similar protections.
South Carolina courts do recognize and enforce postnuptial agreements, although they may apply slightly higher scrutiny compared to prenuptial agreements. The key reason: because the parties are already in a fiduciary relationship as spouses, courts want to ensure neither party was pressured or took advantage of the other.

Who Needs a Prenuptial Agreement in SC?
Prenuptial agreements aren’t only for the ultra-wealthy. If any of the following describes your situation, a prenup may be essential:
- You own a business.A prenup can protect your ownership interest, business assets, and future business income from becoming marital property. Learn more about prenuptial agreements for business owners in SC.
- You’re entering a second or subsequent marriage.If you have children from a prior relationship or assets accumulated during a previous marriage, a prenup helps you preserve those for your family. See our guide to prenuptial agreements for second marriages.
- One or both partners have significant assets or debts.Whether it’s student loans, investment accounts, real estate, or retirement funds, a prenup clarifies what belongs to whom.
- You expect a substantial inheritance.While inherited property is generally considered separate property in South Carolina, commingling funds can blur that distinction. A prenup keeps things clear.
- You or your partner own real estate.Especially if one partner owns the marital home before the wedding, a prenup can address whether that property remains separate or becomes shared.
- You want to define spousal support expectations.South Carolina allows prenups to address alimony, giving both parties predictability if the marriage ends.
Key Takeaway: You don’t need millions in the bank to benefit from a prenuptial agreement. Anyone with assets, debts, children, or a business should consider one.
What Can a Prenuptial Agreement Include in South Carolina?
South Carolina law allows prenuptial agreements to address a wide range of financial topics. Here’s what your prenup can typically cover:
Property and Asset Division
- Classification of separate vs. marital property
- How assets acquired during the marriage will be divided
- Treatment of property owned before the marriage
- Provisions for real estate, investment accounts, and retirement funds
Debt Allocation
- Responsibility for premarital debts (student loans, credit card debt, etc.)
- How debts incurred during the marriage will be allocated
- Protection from a spouse’s existing liabilities
Spousal Support (Alimony)
- Whether alimony will be paid, and if so, how much and for how long
- Waiver of alimony rights (must be conscionable at the time of enforcement)
- Escalation clauses tied to the length of the marriage
Business Interests
- Protection of business ownership and equity
- Provisions for business valuation in the event of divorce
- Limits on a spouse’s claim to business income or appreciation
Inheritance and Estate Planning
- Protection of expected or received inheritances
- Coordination with estate plans, trusts, and beneficiary designations
- Rights to each other’s estates upon death

What a Prenup CANNOT Include
Not everything is fair game in a prenuptial agreement. South Carolina courts will not enforce provisions that:
- Determine child custody or visitation.Courts decide custody based on the child’s best interests at the time of divorce under SC Code § 63-15-240—not based on an agreement made before the child was even born.
- Set or waive child support.Child support is a right that belongs to the child, not the parents, and cannot be bargained away.
- Include terms that are unconscionable.If a prenup is grossly unfair to one party—especially at the time of enforcement—a court may decline to enforce it in whole or in part.
- Encourage or incentivize divorce.Any provision that creates a financial motive for one party to end the marriage may be struck down.
- Contain illegal provisions.This goes without saying, but any term that violates public policy or law is unenforceable.
How South Carolina Courts Evaluate Prenuptial Agreements
Because South Carolina has not adopted the UPAA, courts rely on case law and equitable principles when evaluating prenuptial agreements. The landmark case often cited is Hardee v. Hardee (355 S.C. 382, 585 S.E.2d 501, 2003), which outlined the framework SC courts use.
The Two-Prong Test for Enforceability
South Carolina courts generally examine two categories of fairness:
- Procedural Fairness (How the Agreement Was Made)
- Were both parties represented by independent legal counsel?
- Was there full and fair financial disclosure by both parties?
- Was the agreement signed voluntarily, without fraud, duress, or undue influence?
- Did both parties have adequate time to review the agreement before signing?
- Substantive Fairness (What the Agreement Says)
- Are the terms reasonable and not unconscionable?
- Is the agreement fair given the circumstances at the time of enforcement—not just when it was signed?
- Does the agreement leave one spouse in a significantly worse position than the other?
A court may refuse to enforce a prenup—or specific provisions within it—if either prong fails. For an in-depth look at what could invalidate your agreement, read our article on enforceability of prenups in South Carolina.
Key Takeaway: An enforceable prenup requires both fairness in process (how it was created) and fairness in substance (what it says). Cutting corners on either can put the entire agreement at risk.
Steps to Creating an Enforceable Prenuptial Agreement in SC
If you’ve decided a prenuptial agreement is right for you, here’s the process we follow at Warner Law to ensure your agreement is thorough, fair, and enforceable:
Step 1: Start the Conversation Early
Begin discussing a prenup well before the wedding—ideally at least 60 to 90 days before your ceremony date. Rushing the process is one of the most common reasons prenups are challenged in court. An agreement signed the night before the wedding raises serious questions about voluntariness.
Step 2: Full Financial Disclosure
Both parties must provide complete, honest financial disclosure. This includes:
- Bank account balances
- Investment and retirement accounts
- Real estate holdings and valuations
- Business interests and ownership stakes
- Outstanding debts and liabilities
- Expected inheritances or trust distributions
Hiding assets or underreporting your financial picture is a fast track to having the entire agreement thrown out.
Step 3: Each Party Hires Independent Counsel
We cannot stress this enough: both parties should have their own attorney. At Warner Law, we can represent one party and will strongly encourage the other to retain separate counsel. This protects both of you and dramatically strengthens the agreement’s enforceability.
Step 4: Draft the Agreement
Your attorney drafts the prenuptial agreement based on your goals, financial disclosures, and discussions. The agreement will address the topics most relevant to your situation—property division, debt allocation, spousal support, business protections, and more.
Step 5: Review, Negotiate, and Revise
Both parties (and their attorneys) review the draft. This is a negotiation—both sides should feel heard and fairly treated. Revisions are normal and expected. The goal is an agreement that both parties sign willingly and confidently.
Step 6: Execute the Agreement
Both parties sign the final agreement. In South Carolina, prenuptial agreements must be:
- In writing(oral prenups are not enforceable)
- Signed by both parties
- Executed before the marriage
Notarization is not strictly required by South Carolina law, but we strongly recommend it as an added layer of authenticity.
Step 7: Store the Agreement Safely
Keep the original signed agreement in a secure location—a safe deposit box, a fireproof safe, or with your attorney. Both parties should retain copies. If you ever need to enforce the agreement, you’ll need the original.
Prenuptial Agreements and Equitable Distribution in SC
South Carolina is an equitable distribution state, meaning that in a divorce, marital property is divided fairly—but not necessarily 50/50. Under SC Code § 20-3-630, family courts consider 15 different factors when dividing property, including:
- Duration of the marriage
- Each spouse’s income and earning potential
- Marital misconduct
- Contributions to the marriage (including homemaking)
- Tax consequences
- Each spouse’s separate property and debts
A prenuptial agreement allows you to opt out of this default framework and define your own rules for property division. Instead of leaving the decision to a judge’s discretion, you and your partner agree in advance how assets and debts will be handled—giving you far more control and predictability.
Without a prenup, equitable distribution in South Carolina means a judge has broad discretion to divide your property in a way they deem “fair.” That may or may not align with what you and your spouse would have chosen.
Postnuptial Agreements: What If You’re Already Married?
If you’re already married and didn’t sign a prenup, it’s not too late. A postnuptial agreement can address many of the same issues:
- Clarifying property rights acquired during the marriage
- Protecting a new business or inheritance
- Addressing changes in financial circumstances
- Providing structure after a period of marital difficulty
Postnuptial agreements face additional scrutiny because spouses owe each other a fiduciary duty. Courts want to ensure that neither party used the marital relationship to gain an unfair advantage. Full disclosure, independent counsel, and voluntary execution are even more critical.

Common Myths About Prenuptial Agreements in SC
Before we go further, let’s clear up some misconceptions that keep people from pursuing a prenup—often to their detriment.
Myth #1: “Prenups Are Only for Rich People”
False. While prenups are certainly important for high-net-worth individuals, they’re equally valuable for anyone with property, retirement savings, a small business, student loan debt, or children from a prior relationship. In fact, many middle-income couples in the Columbia area benefit from prenups more than they realize—because they have fewer resources to absorb the financial shock of an unexpected divorce outcome.
Myth #2: “Asking for a Prenup Means You Expect Divorce”
Not at all. A prenup is a financial planning tool, much like insurance or an estate plan. You don’t buy homeowners insurance because you expect your house to burn down—you buy it because protecting what matters is responsible. The same logic applies to a prenuptial agreement.
Myth #3: “Prenups Are Unromantic and Kill Trust”
The opposite is often true. Couples who go through the prenup process together report better financial communication and clearer expectations. A prenup forces you to have honest conversations about money, debts, goals, and values before you walk down the aisle. That’s a stronger foundation for trust—not a weaker one.
Myth #4: “Courts Throw Out Prenups All the Time”
While it’s true that some prenups are invalidated, this usually happens because they were poorly drafted, lacked full financial disclosure, or were signed under duress. A prenup prepared by an experienced South Carolina family law attorney—with proper process and fair terms—has an excellent chance of being upheld. Learn more about what could jeopardize your agreement in our article on enforceability of prenups in South Carolina.
Myth #5: “We Can Just Use a Template from the Internet”
Using a generic online prenup template is risky. South Carolina has its own legal standards and case law governing prenuptial agreements. An online template may not comply with SC requirements, may omit critical provisions, and almost certainly won’t account for the nuances of your specific situation. The money you save upfront could cost you far more if the agreement is deemed unenforceable.
How Prenuptial Agreements Interact with South Carolina Divorce Law
Understanding how prenups fit within the broader framework of South Carolina divorce law is essential for appreciating their value.
Fault vs. No-Fault Divorce
South Carolina recognizes both fault-based and no-fault divorce. The no-fault ground requires living separate and apart for one year without cohabitation. Fault-based grounds include adultery, habitual drunkenness, physical cruelty, and desertion.
A prenuptial agreement can provide certainty in property division regardless of which type of divorce is filed. Without a prenup, fault can significantly influence how a judge divides property—especially adultery, which may bar an at-fault spouse from receiving alimony.
Alimony Considerations
South Carolina courts can award several types of alimony: periodic, lump-sum, rehabilitative, reimbursement, and separate maintenance and support. The type and amount depend on factors like the length of the marriage, each spouse’s earning capacity, marital misconduct, and standard of living.
A prenup allows you to set your own alimony terms rather than leaving this decision to a judge. This can include specifying the type of support, setting a cap, creating a formula tied to the length of the marriage, or waiving alimony entirely (subject to conscionability at the time of enforcement).
The Role of Mediation and Litigation
If you have a valid prenuptial agreement, it can dramatically simplify the divorce process. Instead of litigating every financial issue—a process that can take months or years and cost tens of thousands of dollars—the prenup provides a roadmap. Many couples with prenups are able to resolve their divorce through mediation or even an uncontested filing, saving time, money, and emotional energy.
Special Considerations for Prenups in South Carolina
Prenups and Retirement Accounts
Federal law (ERISA) governs many retirement accounts, including 401(k) plans and pensions. A prenuptial agreement can address how these accounts are treated, but a Qualified Domestic Relations Order (QDRO) may be needed at the time of divorce to actually divide them. Your prenup should anticipate this.
Prenups and the Marital Home
If one spouse owns the home before marriage, a prenup can clarify that it remains separate property. However, if marital funds are used to pay the mortgage, make improvements, or cover taxes, the non-owning spouse may develop a claim to a portion of the home’s equity—unless the prenup addresses this scenario explicitly.
Sunset Clauses
Some couples include a sunset clause that causes the prenup to expire after a certain number of years. For example, a prenup might become void after 15 years of marriage. Sunset clauses aren’t for everyone, but they can be a useful compromise when one party is reluctant to sign.
Lifestyle Clauses
You may have heard about prenups that address things like social media behavior, weight gain, or household chores. While these “lifestyle clauses” sometimes make headlines, South Carolina courts are unlikely to enforce them. Stick to financial provisions for the strongest, most enforceable agreement.
