The most common modifications after a divorce has been finalized involve child custody, visitation and child support payments. The rights and duties allocated between parents can also be modified, as well as periods of possession and access, and parenting plans.
The requirement for almost any modification is that a material and substantial change of circumstance must have taken place between the last court hearing and the modification. The modification must also be in the best interest of the child.
A reason for such a modification might be that the parent paying child support experiences an increase or decrease in earning power, or if the financial needs of the child change. Some changes to the divorce decree are significant but are not considered modifications.
