Neb. Rev. Stat. §§ 42-362
When the pleadings or evidence in any action pursuant to sections 42-347 to 42-381 indicate that either spouse is mentally ill, a guardian ad litem or an attorney, or both, shall be appointed to represent the interests of such spouse. Such guardian's fee or attorney's fee, or both, shall be taxed as costs when allowed by the court and shall be paid by the county if the parties are unable to do so. When a marriage is dissolved and the evidence indicates that either spouse is mentally ill, the court may, at the time of dissolving the marriage or at any time thereafter, make such order for the support and maintenance of such mentally ill person as it may deem necessary and proper, having due regard to the property and income of the parties, and the court may require the party ordered to provide support and maintenance to file a bond or otherwise give security for such support. Such an order for support may be entered upon the application of the guardian or guardian ad litem or of any person, county, municipality, or institution charged with the support of such mentally ill person. The order for support may, if necessary, be revised from time to time on like application.
