The Maryland Petition/Motion to Modify Child Custody/Visitation DR7 — Instructions is a form used to request a change in the existing child custody and/or visitation order. This form is used when a parent or guardian needs to modify the terms of the custody or visitation order previously issued by the court. The DR7 form includes instructions on how to properly fill out the form, including information on how to request a hearing date. There are two types of DR7 forms: one for initial requests and one for subsequent requests. The initial DR7 form is used to request a change in custody and/or visitation for the first time. The subsequent DR7 form is used to request a change in custody and/or visitation after a previous request has already been made. Both forms include instructions on how to fill out the form, how to request a hearing date, and how to send the form to the court.
