(ohio)in the beginning of all this,the child was living with me(paternal gr parent),and i never denied the maternal grandparent visitation,,then my son took the child(which he had custody at the time)then went back with his wife(abusive relationship) and the 2 of them signed custody over to the maternal grand parents~i have tried and tried to visit with the child,the maternal gr parents dont return any calls...or letters..and there are 2 other siblings, of this child that live with me,one age 10,the other age 5,they are half siblings,but they havent seen their sister either since all this,,so only after 3 months of me trying to talk with the maternal gr parents did i file for the visitation,the case is to be heard on the 15 of october,then they go and file this motion for lack of juristriction???,so i dont know what this is...thanksWhat is the name of your state (only U.S. law)?
