Neb. Rev. Stat. § 25-415
If the parties have agreed in writing that an action on a controversy shall be brought only in another state and it is brought in a court of this state, the court will dismiss or stay the action, as appropriate, unless (1) the court is required by statute to entertain the action; (2) the plaintiff cannot secure effective relief in the other state, for reasons other than delay in bringing the action; (3) the other state would be a substantially less convenient place for the trial of the action than this state; (4) the agreement as to the place of the action was obtained by misrepresentation, duress, the abuse of economic power, or other unconscionable means; or (5) it would for some other reason be unfair or unreasonable to enforce the agreement.
