Changes to a Permanent Parenting Plan is called a parenting plan modification. There are laws and rules that must be followed in order to file a parenting plan modification and for a Judge to be allowed to change a parenting plan. A parenting plan cannot be changed simply because one parent no longer likes a certain aspect of the plan. The success of a modification depends on the facts of the case. It is important that you contact an attorney with experience in the court in which your modification is filed.
