My father has been diagnosed with stage 4 bone cancer that is not curable. He has a 9 year old daughter who is my sister. Technically half sister because we have different moms. Her mom is a drug addict and is out of the picture. My dad is in complete denial of the cancer and at this stage has made no will or anything of the sort. I am sure I will be taking my little sister and raising her. Will I have to go through the courts to do this? Do I need to contact an attorney? Will I run into any problems? My dad also has a house that he currently has a mortgage on, and he just received a loan modification....what is going to happen with that house? I am willing to move in and take over payments but will I have to get the house refinanced in my name? I have no credit and would not get approved at this time. He also doesn't have health insurance and I have heard that the hospital will try take or lien the house to get the bills paid? Is this true? I don't know what do to or the appropriate steps to take.
