Commonly, enforcement efforts might be necessary when a parent fails to adhere to a custody schedule. Many parents work out a schedule to determine where children will live during weekdays, weekends, and school holidays. Disobeying these requirements can result in an enforcement action. Interference in the relationship between a child and the other parent can occur, and efforts to interfere to the detriment of the other parent can result in a motion for contempt depending on the language of the parenting plan. Other issues arise when one parent oversteps their legal rights when making a decision for the child, as custody agreements set out a range of guidelines that cover everything from medical care to religious beliefs. Making these decisions unilaterally without the power to do so might be considered a violation of the custody agreement.
