Here is the situation: A friend of mine has a grand daughter in Oregon, where she lives with her mother. My friend lives in California. The mother has custody, but she is a drug user, grows marijuana at her home with no medical card. She shifts the grand daughter to other relatives or friends. She thrashed the house which she rents from my friend. The father lives in California. Is there any way that the grandmother could gain custody, and relocate her to California. The grand daughter apparently has some issues because of the instability of her living conditions & environment. By the way, she is 10 years old. I would appreciate any advice.
