Unless there is some formal court order if the father passed away, you have sole custody of the child. You can discuss with an attorney preparing some power of attorney if you need your mother to be able to act on your behalf if the child is in need of medical care, or if the mother needs to get medical records or school records or the like. You could also give your mother joint custody, but that is not something that should be done without a lot of thought since you could find yourself in a custody battle with your mother. If the written agreement has sufficed up until now, I would not recommend going for joint custody without at least consulting with a family law attorney beforehand.
