the total cleaning out of his house he will never return to, and now that I decided to rent it to help with some funds for his monthly nursing home expense, the "landlord" of his house. I must go to the pharmacy to pickup his refill meds then take them to the nursing home, as his HMO wont mail them to the home. I travel 21 miles one way twice a month to do this chore. Now I'm not bitter about this, but between taking care of his house, and running errands for meds, I think I should at least get gas money from his pocket vs mine. I'm not greedy. I am executor to his estate, and worry about what is proper and what isn't.
To keep it "proper", especially if there are other relatives who might raise questions laters, have a Care Agreement drawn up that spells out the details of what you are recieiving and what you are doing. Again, this is just a sensible practical step. It in no way diminishes the fact that you are acting in love and compassion.
I don't know what other documents you have in place -- POA, etc, -- but seeing a lawyer who specializes in Elder Law might be a good investment at this point.
Good luck to you and to your father!
