When divorced couples with children start their new lives separate and apart from each other, they cannot be totally free and clear from each other because they have a responsibility to co-parent. In Pennsylvania, divorced parents will usually have a custody agreement or custody order in place that governs the custody arrangement between the parents. The agreement or order will, among other things, provide for a physical custody schedule that will specifically define when each parent will have the children. There are always minor issues that arise that cause the parents to have to verbally modify the agreement to suit the particular situation. For example, one parent may be sick during that parent’s custody time, so the other parent by agreement with the sick parent may keep the children during that time, even though the custody agreement or order says otherwise. These issues are common and when they arise, they emphasize the importance of parents being able to amicably co-parent, even though their marriage was irretrievably broken. Sometimes, however, one parent wants to move or relocate to a new place. When this occurs, it can have a major impact on the practicality of the custody agreement or order.
