Non-Compete Agreements in South Carolina: Are They Enforceable?

Federal law does not comprehensively regulate non-compete agreements at the national level. The Federal Trade Commission (FTC) has issued guidance and proposed rules on non-competes, most recently proposing a ban on most non-compete clauses in 2023, but those rules are not yet federal law and remain subject to legal challenge. The National Labor Relations Act (29 U.S.C. § 151 et seq.) may restrict overly broad non-competes that interfere with employee organizing rights, but this is narrow.

Instead, non-compete enforceability is primarily governed by state law. States range from completely unenforced (California) to fully enforced with minimal restrictions. The Defend Trade Secrets Act (18 U.S.C. § 1836) protects trade secrets federally but does not establish non-compete rules. Most employers rely on state common law and statute. Employees subject to non-competes should consult state law where they work and where they plan to work post-employment.

South Carolina enforces non-compete agreements under South Carolina Code § 34-1-2, which permits restrictions on competition as long as they are reasonable. The statute creates a presumption of unreasonableness for agreements that restrict an employee's ability to work in their trade or profession, but this presumption is rebuttable—meaning an employer can prove the restriction is reasonable by demonstrating a legitimate business interest.

South Carolina applies the three-part Karpinski test to determine enforceability: (1) does the restriction protect a legitimate business interest (trade secrets, confidential business information, substantial relationships with prospective customers, or ongoing business relationships), (2) is the time restriction reasonable, and (3) is the geographic scope reasonable. Unlike some states, South Carolina has no statutory cap on duration and no statutory definition of what geographic areas are reasonable. Courts examine the facts of each case.

South Carolina law is notably more employee-protective than federal baseline because the statute explicitly presumes unreasonableness. Employers must affirmatively prove reasonableness; the burden is not on employees to prove the restriction is overbroad. The state has adopted the "blue-pencil" doctrine, which allows courts to modify or "blue-pencil" overly broad non-compete agreements to make them reasonable and enforceable, rather than striking them down entirely.

Covered employers include any business with employees in South Carolina, regardless of company size. The statute applies to non-competes, non-solicitation clauses, and confidentiality agreements that restrict competition. South Carolina courts have held that an agreement need not be labeled a "non-compete" to be enforceable as one if its terms restrict competition. Remedies for breach include injunctive relief (court order to prevent the employee from working for a competitor) and damages for economic harm.

Non-compete agreements may be unenforceable in South Carolina under several circumstances. First, agreements that lack a legitimate business interest protecting trade secrets, confidential information, or customer relationships are presumed unreasonable and unenforceable. An employer must prove the existence of one of these interests; generic assertions of competition are insufficient.

Second, restrictions that are unreasonable in duration are not enforceable. While South Carolina has no statutory cap, courts have held that restrictions lasting more than three to five years are presumptively unreasonable absent extraordinary circumstances. A restriction for "the employee's lifetime" or without temporal limit is almost certainly unenforceable.

Third, geographic restrictions that exceed the employer's legitimate business territory are unenforceable. If an employer operates only in Greenville County but restricts an employee from working in competition statewide or nationwide, the geographic scope is likely unreasonable.

Fourth, South Carolina recognizes an "employee mobility" exception. Employees possess a general right to earn a livelihood and work in their chosen profession. Non-competes must not effectively prevent the employee from finding comparable employment. If the restriction is so broad that the employee cannot reasonably find alternative work, courts may deem it unreasonable as a matter of public policy.

Fifth, South Carolina does not enforce non-competes against employees who are terminated without cause or wrongfully terminated, though case law on this point is developing. Agreements imposed as a condition of continued employment after initial hiring are more closely scrutinized for consideration (whether the employee received something of value in exchange).

Sixth, non-competes imposed on low-wage workers with limited bargaining power may be scrutinized more carefully for reasonableness, though South Carolina has no blanket exception for any employment category. Finally, if an employer's conduct triggers equitable principles (such as laches or estoppel), enforcement may be denied.

Step 1 — Document Everything. Obtain a copy of your non-compete agreement and note the date you signed it, the consideration you received (salary, promotion, continued employment), and the specific restrictions on scope, duration, and geography. Preserve all communications about the agreement, including emails from your employer explaining the terms. Keep records of what you were told about the agreement's enforceability and any promises made about its application. Take screenshots of the agreement as it appears in any employee handbook or system.

Step 2 — Understand Your Options Before Signing or Post-Signing. If you have not yet signed, negotiate the non-compete's scope, duration, and geography to make it more reasonable. Request that your employer narrow the restricted territory to areas where it actually operates or provide written confirmation that the agreement will not prevent you from working in your field. If you have already signed and believe the agreement is unreasonable, consult an attorney immediately—do not wait until you are threatened with enforcement. Some agreements are unenforceable and you may have leverage to challenge or modify them.

Step 3 — Consult an Employment Attorney (South Carolina). Before changing jobs or accepting a competing position, contact a South Carolina employment lawyer to evaluate whether your non-compete is enforceable. Provide the attorney with a copy of the agreement, the date you signed it, your job duties, your compensation, the identity of your former employer, and the location and nature of the new job you are considering. Many South Carolina attorneys offer free initial consultations. An attorney can advise whether your specific non-compete would likely be enforced by a court and what risks you face by working for a competitor.

Step 4 — Assess Litigation Risk. If your former employer threatens enforcement or files a lawsuit, understand that South Carolina courts apply the three-part reasonableness test. Your attorney will evaluate: (1) whether the employer has a legitimate business interest you actually had access to, (2) whether the duration is reasonable (typically 1-3 years passes; longer durations are scrutinized), and (3) whether the geographic area is reasonable (limited to areas where the employer actually operated). If the agreement fails any prong, it is likely unenforceable or subject to blue-pencil modification. If your employer files for a temporary restraining order or preliminary injunction, you have a right to be heard in court and present evidence of unreasonableness.

Step 5 — Respond to Enforcement Action or Demand. If you receive a cease-and-desist letter or lawsuit, respond promptly through your attorney. Do not ignore it. File an answer or response in court if sued. Raise all defenses, including lack of legitimate business interest, unreasonable scope, unreasonable duration, unreasonable geography, and public policy arguments about employee mobility. Request that the court blue-pencil the agreement if it is partially overbroad. Provide evidence of any wrongful termination, lack of consideration, or other circumstances suggesting the agreement should not be enforced.
