My dad has dementia and is too far along to make decisions. He refused to write a will or assign a POA when he could make decisions. He has a lot of debt and land. The land is in his and my mom's (who died last year) name. Two family members live on the land, but we don't know what to do so that we can continue living on the land after dad dies. What can I do legally to not only help dad, but to help the family not lose the land?
