I hear this often that once an agreement is reached that one party in a custody or divorce feels the other has not held up their end of the agreement. So what are the options available in a situation like this? In my view the best option, although there are several, would be to get an experienced family law mediator to help you resolve the issue.
Many times disagreements and conflicts regarding children can lead to the child being placed inside the conflict, the worse place for them to be. As a mediator, I can help you resolve the issue from a neutral point of view and be objective in finding a solution. Although divorce is the end of a marriage it is the start of new coparenting and both parties should comply in good faith with the children's best interest in mind.
