<human>: Give me the gist of the text in a nutshell

My best friend's brother was going through a separation with his wife. He was living with my friend after his wife kicked him out and brought in her new boyfriend. They shared custody of a 3 year old boy. They weren't legally divorced yet and had only been living apart for a couple months. Then one day at work, the guy died suddenly. Of course, the child immediately went to mother. 

Now it's been 2 months since the guy's death and the mother is not letting any of his family see the little child. She has moved a couple hours away and changed her phone number. The only person willing to talk to his family is her mother who is saying, ""NAME says it is not a good time. She is trying to start her new life." 

Reddit, is there anything my friend and her family can do? Before this all happened they were very involved with the child's life and now they are being pushed out of it. 

Also, the state is Kentucky, if that matters for legal rights.
<bot>: Parents sperate, father dies, and now mother is refusing to let paternal family see child. What can they do?
