[header] How to enforce visitation rights [title] Review your divorce or paternity order. [step] When parents of a minor child split up, the divorce or paternity order establishes several rights and responsibilities. For example, the order will establish which parent has residential custody, which parent pays child support, and schedule visitation for the non-custodial parent. <sep> (A) [substeps] This collection of orders is called a parenting plan. The plan is intended to help reduce conflict and refocus the parties away from their strife and back to their children. (B) [substeps] Sometimes liens can be enforced by the non-custodial parent so she and her family can settle for the same amount of custody. You will need to research your state's custody and visitation requirements before you proceed. (C) [substeps] A lot of states require the non-custodial parent to have a primary caregiver in state custody. In an unrelated state in which the parent is the child's legal guardian, this requires a change of custody as well. (D) [substeps] You and the other parent cannot be separated from each other. Make sure you understand all of these rules prior to filing your divorce or paternity order.
