When child custody, visitation, or support is contested in a divorce or other legal proceeding, courts may appoint a guardian ad litem (often an attorney with experience in family law matters) to investigate and make independent, objective recommendations to the court of what is in the best interest of the child. The guardian ad litem will typically interview the child, the parents, and other people who have contact with the child, and may subpoena witnesses to testify at court hearings, examine and cross-examine witnesses at hearings. The guardian ad litem may also testify regarding her investigation of the circumstances, conclusions, and recommendations to the court.

In Nebraska, when child custody, visitation, or support is contested in a divorce or other legal proceeding, the court has the authority to appoint a guardian ad litem. This individual is often an attorney with experience in family law matters. The role of the guardian ad litem is to serve as an independent investigator and advocate for the best interests of the child involved in the proceedings. They conduct interviews with the child, parents, and others in the child's life, and have the power to subpoena witnesses for court hearings. Additionally, they can examine and cross-examine witnesses during these hearings. The guardian ad litem compiles their findings and provides testimony to the court, offering recommendations based on their investigation. The court considers the guardian ad litem's report and testimony when making decisions regarding custody, visitation, or support to ensure the child's best interests are prioritized.
