A child custody petition can mean several things in a custody situation. Here are some of the ways that this phrase is used.

1. A child custody petition is a custody form that begins a custody case. In some states, a parent files a custody petition to get a case started. After the first parent files the petition, the other parent has the opportunity to respond. The case then moves on from there.

2. A child custody petition is a form where a parent requests custody. Sometimes a custody petition refers to one parent seeking custody of the child. This form usually requires that the parent also turn in a custody agreement or parenting plan that contains a regular custody schedule, a holiday schedule, vacation time, and any special events.

3. A custody petition can be a request for a child custody modification. If a parent wants the current custody order changed, they can file a petition for a custody modification.
