Section 42-1006 - Enforcement(1) A premarital agreement is not enforceable if the party against whom enforcement is sought proves that: (a) That party did not execute the agreement voluntarily; or(b) The agreement was unconscionable when it was executed and, before execution of the agreement, that party:(i) Was not provided a fair and reasonable disclosure of the property or financial obligations of the other party;(ii) Did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided; and(iii) Did not have, or reasonably could not have had, an adequate knowledge of the property or financial obligations of the other party.(2) If a provision of a premarital agreement modifies or eliminates spousal support and that modification or elimination causes one party to the agreement to be eligible for support under a program of public assistance at the time of separation or marital dissolution, a court, notwithstanding the terms of the agreement, may require the other party to provide support to the extent necessary to avoid that eligibility.(3) An issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law.Neb.
