My father is 80 years old and just spent almost 2 months in and out of hospitals and rehabilitation facilities. He has no living will, no durable power of attorney the only document in place is the Georgia Advance Directive for Healthcare which my older sister is listed first on, i am second and my older brother is third. I need to know how to gain legal rights to his estate as well as his healthcare decisions due to the fact that he is no longer capable of making decisions on his own, he can not walk, he is completely inmobile and due to the fact my older sister (mentioned above) is on disability and is acting as his caregiver. I am afraid for is well being. Please help!
