When the parents of minor children split up, a child custody agreement is used to detail the roles and responsibilities of each parent. The custody agreement (sometimes called a parenting agreement or parenting plan) explains how physical and legal custody will be handled, as well as the visitation rights the non-custodial parent. If either parent refuses to comply with the visitation agreement, each parent should seek the assistance of a visitation rights lawyer, child custody law firm or family law attorney. Attorneys can work to ensure that both parents honor the parenting time and visitation agreements, or go to court, if necessary, to enforce or modify the agreement. Visitation rights lawyers can also work with other caregivers and family members, such as grandparents, to establish legally enforceable visitation rights.
