In Texas, a morality clause is a provision in a court order that states that neither parent can have a romantic partner stay the night while the children are present. The purpose of a morality clause is to prevent parents from exposing the children to several new dating partners. If there is a morality clause in your court order, your options are: get married, risk losing your kids if you violate the morality clause, or during the other parent’s possession of the children, stay the night with your partner assuring that the children are not present.
If the morality clause is violated, Judges in Texas may and often will change custody of the children. Judges will also often enforce these provisions and the parent in violation may end up serving jail time and paying fines for the violations.
