I have a 12 yr old adopted daughter which is my granddaughter her adopted father has passed away I need to make a will to make sure my live in

If you adopted your granddaughter she will normally be considered your daughter now for all purposes, and you should be able to make a Will and appoint a guardian for her. The tricky part in your case is whether her biological parents' rights were terminated completely enough to prevent custody from reverting to her. You may not be able to control that. So, while getting a well-drafted, properly executed Will in place is the right place to begin, it may not be all that is necessary to ensure that your choice for guardian actually is the person allowed to take custody of her. My suggestion is to find an estate planning attorney who is familiar with adoption laws, especially in intra-family adoptions (where you adopt a grandchild, as in this case), and have the attorney help you figure out what you can do and take the appropriate steps as well as you can.
