Parenting plans—also known as custody agreements or custody and visitation agreements—are proposals submitted by parents for how issues involving children should be handled following a divorce or other proceeding in family court. The court will usually request the parents submit such a document proposing how conservatorship (decision-making), custody or possession, support, and other issues will be handled. The court may adopt some or all of these proposals and include them in the court’s order (divorce decree, child support and custody order), at which point the become legally enforceable.

In many states there is a standard possession order (SPO) that serves as the default terms for such matters, and as a useful starting point for parents who wish to modify it by agreement.

In Michigan, parenting plans are a crucial component of family law proceedings involving children. These plans outline how divorced or separated parents will share decision-making responsibilities (conservatorship), custody, parenting time (visitation), child support, and other child-related matters. Michigan law encourages parents to work together to create a parenting plan that serves the best interests of the child. If the parents can agree on a plan, the court will typically review it to ensure it meets the child's needs and, if appropriate, incorporate it into the final court order, making it legally binding. If parents cannot agree, the court will decide on these matters. Michigan does not use the term 'standard possession order' (SPO), but the state does have established guidelines and factors that courts consider when determining custody and parenting time. These guidelines aim to provide a framework that can be adjusted to fit the unique circumstances of each family.
