A Maryland Petition/Motion to Modify Custody/Visitation is a legal document that a custodial parent or non-custodial parent can file in court to modify the existing custody or visitation order for the child. It is used to either change the terms of visitation or custody, or to ask for a new arrangement entirely. Depending on the situation, the court may also order a change in child support payments. There are two different types of Maryland Petition/Motion to Modify Custody/Visitation: 1. Joint Petition/Motion to Modify Custody/Visitation: This is filed when both parents agree to the change in custody/visitation and submit a joint petition to the court for approval. 2. Petition/Motion to Modify Custody/Visitation with Notice: This is filed when one parent does not agree to the change in custody/visitation. The petitioner must serve the other parent with legal notice of the petition. The non-petitioning parent then has the opportunity to respond to the petition and present evidence at the hearing.
