How can i change my decree without a lawyer?

Any modification of the decree must be approved by the court to be enforceable.  Thus, if you both come to agreement, you can submit a stipulation with the changes to the court for approval.  If you both don't agree, then you need to file a petition for modification.  I recommend having an attorney look over anything you file with the court.  Some attorneys willl agree just to bill you to review documents.     Donna Miller Grefe & Sidney 515-245-4300
