NDAs are enforceable in every state — what changes in Wisconsin is the statute behind them, the carve-outs the law forces into them, and how courts treat NDA terms that drift toward non-compete territory. This page covers the Wisconsin layer; the download is our standard mutual/unilateral NDA, ready to adapt.

How Wisconsin handles non-disclosure agreements
Wisconsin courts have extended the red-pencil statute to confidentiality covenants tied to employment — an overbroad definition of 'confidential information' can void the entire clause, a risk unique to Wisconsin drafting. Two layers apply everywhere, including Wisconsin: the federal Defend Trade Secrets Act gives a federal claim for trade-secret theft, and the federal Speak Out Act voids pre-dispute NDAs over sexual assault and harassment. The state layer above is what changes when you cross a border — verify it before relying on a clause.
Wisconsin non-disclosure agreement FAQs
Are NDAs enforceable in Wisconsin?
Yes — confidentiality agreements protecting trade secrets and legitimately confidential business information are enforceable in Wisconsin, under uniform Trade Secrets Act (Wis. Stat. §134.90). The limits arrive at the edges: terms so broad they operate as a non-compete, and clauses muzzling legally protected disclosures (harassment claims, whistleblowing, wage discussions).
Can an NDA cover sexual harassment claims in Wisconsin?
No additional state statute; the federal Speak Out Act (2022) voids pre-dispute NDAs covering sexual assault and harassment claims. Whatever the state layer says, the federal Speak Out Act independently voids pre-dispute confidentiality terms covering sexual assault and harassment disputes nationwide.
Can an NDA stop someone from working for a competitor in Wisconsin?
§103.465's red-pencil rule has been applied to NDA and non-solicit terms — one unreasonable element voids the covenant entirely. The drafting rule: define confidential information specifically, exclude general skills and knowledge, and use a separate, state-compliant non-compete if mobility restraints are actually needed.
How long should an NDA last in Wisconsin?
For true trade secrets, protection can be indefinite — secrecy is the legal status, not the clause. For ordinary confidential business information, 2–5 years is the enforceable norm; Wisconsin courts treat perpetual restrictions on non-secret information skeptically. Tier the clause: indefinite for trade secrets, fixed-term for everything else.
