Nebraska Revised Statutes Chapter 25. Courts; Civil Procedure § 25-21,185.11. Civil actions to which contributory negligence is a defense;  release, covenant not to sue, or similar agreement;  effect

(1) A release, covenant not to sue, or similar agreement entered into by a claimant and a person liable shall discharge that person from all liability to the claimant but shall not discharge any other persons liable upon the same claim unless it so provides. The claim of the claimant against other persons shall be reduced by the amount of the released person's share of the obligation as determined by the trier of fact.

(2) A release, covenant not to sue, or similar agreement entered into by a claimant and a person liable shall preclude that person from being made a party or, if an action is pending, shall be a basis for that person's dismissal, but the person's negligence, if any, shall be considered in accordance with section 25-21,185.09.
