How to comfort my terminally ill Dad and get the family leaches out of his home?

Genevieve, sorry about your Dad. Assuming he understands the situation, you can bring hospice in. Tell the other family members that Dad needs peace and quiet and visitors --- one or two at a time. Someone needs to be the POA and have medical proxy. You may need to make other arrangements for the grandson even if you claim it to be for an initial period until hospice is set up. Change the locks if necessary. Hire caregiving help if family can't be there. Talk to hospice for suggestions and they will assist with many of the arrangements. Good luck.

It makes my blood boil when the vultures descend. Make it clear to them they are to touch nothing, take nothing and if they do you will file a larceny complaint and have them hauled away in chains. Change the locks. Photograph every room. If grandchild takes so much as a fork without asking, get an order of protection immediately.
