OKAY I HAVE A 11 Y.O. DAUGHTER AND HER DAD HAS A COURT ORDER TO PAY CHILD SUPPORT?

SINCE SHE WAS 1 Y.O. WE HAVE NOT BEEN TOGETHER SINCE THEN NOR ARE WE MARRIED. WHEN HE WAS IN THE SERVICE AND WENT TO WAR, I LEFT TO MY HOME IN THE ISLAND AND THE MILITARY SEND ME THE CHILD SUPPORT PAYMENT FOR LIKE ABOUT A YEAR BUT AS SOON AS HE FINISHED HIS TIME IN THE MILITARY AND RETURNED HOME THE CHECKS STOPPED COMING, I DECIDED TO THE MOVE BACK TO THE STATES NOT BECAUSE OF MY MOTHER. AND HE STILL DOESN'T HELP MONETARY WISE, ALL HE DOES IS BY HER EXPENSIVE GYM SHOES EVERY MONTH, AND HE SPEND TIME WITH HER EVERY WEEKEND AND I HAVE NO PROBLEM WITH THAT BUT OUTSIDE OF THAT NOTHING AT ALL. I AM PLANNING ON MOVING BACK TO THE ISLAND AND I KNOW HE IS GOING TO NOT WANT TO, I HAVE SPOKEN TO MY DAUGHTER AND SHE LOVES IT AND ALSO WANT TO MOVE BACK. I WANTED TO KNOW WOULD I HAVE A PROBLEM (LEGAL WISE) BECAUSE OF THAT, CONSIDERING THE WHOLE MOVE AWAY LAW. I KNOW HE IS AFRAID OF THE LAW AND THE WHOLE CHILD SUPPORT DEPARTMENT BUT I WANT TO MAKE SURE I AM DOING EVERYTHING UNDER THE LAW AND NOT BREAKING ANY. HOW DOES THE MOVE AWAY LAW WORKS???
