Covenant Not to Sue

A covenant not to sue is an enforceable promise, typically in a settlement or release agreement, that one party will not file suit against another over a defined dispute. Unlike a full release, it does not necessarily extinguish the underlying claim; it bars the covenantor from asserting it.

The practical difference matters in multi-party litigation. With a release, the claim against all jointly liable parties is reduced; with a covenant not to sue, only the named beneficiary is protected, leaving the covenantor's right to sue other co-defendants intact. California courts respect this distinction in joint-tortfeasor and indemnity scenarios.

Drafting matters: the covenant should clearly identify the parties protected, the claims covered, and any carve-outs, such as enforcement of the settlement itself or future unrelated claims. A breach of the covenant exposes the breaching party to a damages claim, typically including the legal fees the protected party incurred defending the suit that should not have been filed.
