My daughter left the state of Florida were I live. She left her son with us until she comes back in 3 months. Is there ant chance I could file for custody of the child and win. The father is does not want custody and is OK with us going for custody

There is a good possibility you could file and win at least temporary custody. I recommend getting a consultation from a local attorney to weigh your options.

Why would you want to do this? Is there a reason to believe your daughter is not a fit parent? Did you have a specific agreement under which you agreed to take care of your grand child for the time your daughter will be out of the state? Is your daughter in the military? What is the reason for her absence? These are all questions that will need to be addressed at any potential hearing for temporary custody. This is not legal advise and I am not an attorney. Always consult a qualified attorney.

WHY is a very good question. Before we can advise you we would need to know the answers to the questions imrachelsmommy asks. Did the mother leave any paperwork giving you the right to care for the child? If not, you may have a problem getting medical care.
