When life changes, even the most carefully crafted court orders can no longer function in a way that is practical. Moving, changing jobs, growing children, new romantic interests, or a parent no longer doing their part for the best interest of the children are just some of the reasons parties find themselves in need of modifying a previous court order.  What is important to remember is that judges generally prefer when a party is considering a change in life circumstances, that the party seek the modification first.  Dealing with a judge refusing to grant a modification after substantial changes have taken place can be costly and detrimental.
