I as of now have 50/50 authority with my ex. He will not speak with me. I have sent a letter from a legal counselor to him about his refusal to convey. My 10 year old child let me know that his father is resigning in year and a half. He and his significant other are taking a gander at houses to purchase on the west coast for when he resigns. We live on the east coast. I need my child to be with me most of the year and afterward he can visit his father whenever school is out. I know whether I attempt to talk with him regarding what their arrangements are, he will not react. Would it be advisable for me to contact a legal counselor currently concerning this? Would it be a good idea for me to attempt to talk with my ex first with regards to their arrangements and care? This isn't about "will I get care?" It's tied in with finding a way the ways to ensure I'm giving My very best for keep guardianship of my child when they move.
