South Carolina Non-Disclosure Agreement (NDA) Review
South Carolina's Trade Secrets Act contains a provision many states lack: a contractual duty to keep a trade secret confidential is not void just because it has no time or geographic limit. That makes a South Carolina NDA potentially longer-lasting than one signed elsewhere, at least for genuine trade secrets. Meanwhile, any non-compete or non-solicit inside the NDA faces strict construction and no judicial rewriting.

Confidentiality & trade secrets in South Carolina
South Carolina protects trade secrets under its version of the Uniform Trade Secrets Act, and the federal Defend Trade Secrets Act applies on top. A reasonable NDA is enforceable, but courts still look at scope, an over-broad definition of "confidential information" with no exclusions is the most common weakness.
Watch for a non-compete inside the NDA
Enforceable if reasonable and supported by consideration; courts strictly construe and will not rewrite overbroad terms.
A confidentiality agreement should protect information, not restrict who you can work for. If an NDA in South Carolina also tries to bar you from competitors or from soliciting contacts, treat that as a separate restrictive covenant and judge it by South Carolina's non-compete rules above.
Can a South Carolina NDA last forever?
For trade secrets, potentially yes. S.C. Code 39-8-30(D) provides that a contractual duty to maintain the secrecy of a trade secret, or to limit its use, must not be considered void or unenforceable because it lacks a durational or geographic limitation. Section 39-8-30(B) adds that an employee who knows or should know of a trade secret owes a duty not to use or disclose it, independent of any written contract.
That rule protects trade secrets, not every item labeled confidential. Ordinary confidential information that falls short of a trade secret is a stronger candidate for a defined end date.
What happens to an overbroad South Carolina non-solicit?
South Carolina courts construe restrictive covenants strictly against the employer, and in Poynter Investments v. Century Builders of Piedmont (2010) the state Supreme Court declined to rewrite an unreasonable restriction. If a non-solicit or non-compete in your NDA is too broad, it is likely to fail rather than be trimmed.
Misappropriation claims under the Trade Secrets Act must be filed within three years after discovery or when it reasonably should have been discovered (39-8-70), and attorney fees can be awarded for bad faith claims or willful misappropriation.
For a South Carolina employee, that combination is worth weighing: confidentiality duties tied to real trade secrets may run indefinitely, while the restrictive covenants around them are more likely than in most states to fall away completely if they are overdrawn.

South Carolina NDA FAQ
Is an NDA enforceable in South Carolina?
Yes, a reasonable confidentiality agreement is generally enforceable in South Carolina, backed by the state’s Uniform Trade Secrets Act and, at the federal level, the Defend Trade Secrets Act. What matters is scope: an NDA with an over-broad definition of "confidential information," no standard exclusions, or a perpetual term is far weaker than it looks and worth narrowing.
Can an NDA include a non-compete in South Carolina?
NDAs sometimes bundle in non-compete or non-solicitation language, and in South Carolina a reasonable non-compete can be enforceable, Enforceable if reasonable and supported by consideration; courts strictly construe and will not rewrite overbroad terms. A confidentiality agreement should not quietly restrict who you can work for, so flag any non-compete inside it.
What makes an NDA fair in South Carolina?
A sound NDA defines confidential information narrowly, includes the standard exclusions (public information, what you already knew, what you independently develop, and what a third party gives you), has a defined term rather than a perpetual one, and does not include a broad "residuals" clause or a hidden non-compete. ClauseAudit checks each of these against South Carolina law.
Can South Carolina enforce a non-compete buried in an NDA?
South Carolina is one of 34 jurisdictions where a non-compete is generally enforceable if reasonable in duration, geography and scope. Enforceable if reasonable and supported by consideration; courts strictly construe and will not rewrite overbroad terms. Confidentiality obligations are a separate question and are not affected by any of that, which is why a restraint tucked into an NDA deserves reading on its own terms rather than as part of the secrecy clause.
Should I still ask for a time limit on a South Carolina NDA?
Yes, for anything that is not a true trade secret. Section 39-8-30(D) only saves open-ended secrecy duties for trade secrets. Asking for a defined term, such as a few years, for general confidential information, and limiting the indefinite duty to identified trade secrets, keeps the agreement fair and closer to what a court would enforce.
Does South Carolina restrict harassment NDAs?
The key protection is the federal Speak Out Act, which makes a nondisclosure or nondisparagement clause agreed before a sexual assault or sexual harassment dispute unenforceable in that dispute. The Defend Trade Secrets Act separately protects confidential reports of suspected legal violations to officials and attorneys.
