Pennsylvania - I received a letter in the mail from my son's paternal grandmother stating that she is suing me for partial custody, under the guidelines that "I make it difficult for her to spend time with her grandson." she is asking for partial custody, over night and to be involved in his life. She sees my son every week on the designated days that his father has him and he stays the night with her just about twice a month. His father will be going into the national guard after our court date of 6/11. I have no lawyer and when we go to court it will be my son's father, my son's paternal grandmother now and me. I do not want to feel ganged up on by them. I also have no issue with my son seeing his grandmother. He loves her dearly. I just feel that, while his dad is around, he should be responsible for our son seeing his grandmother. While he is away, of course I would allow my son to visit her. Although I believe she feels that I won't. Does she have a chance with custody?
