Nebraska courts, like all other courts throughout the nation, make child custody determinations based on "a child's best interests." Unfortunately, the child's best interest standard is purposefully vague, as every child's circumstances and best interests are different. That said, most courts take several of the same factors into consideration when determining with which parent a child should live. Some such factors courts consider include the location of the child's school, each parent's living situation, each parent's schedule, the age and sex of the child and the child's wishes. Most courts will also consider any parental history of alcohol or drug abuse, violence and criminal behavior.
