NDA by State

An NDA is governed by state contract law. Enforceability depends on how clearly the confidential material is defined and whether the term is reasonable.

Governing law by state

Most NDAs name the state whose law applies. Courts in the named state will weigh the reasonableness of scope and duration before enforcing.
