This is a follow-up to your other question. I do not believe you are going to be able to resolve this on your own. I think that you need to retain a probate attorney and discuss obtaining guardianship and conservatorship over your father. Your brother will likely contest your appointment, but if you can prove your allegations of financial wrong-doing, (which appear to breach your brother's fiduciary duties to your father), then the court may well land on your side.

There may be wrongdoing here. You may be completely right and your brother may be completely wrong. You could seek a guardianship if your father is incompetent and possibly get the court to void the DPOA your brother has.
But, it might be best to ignore your brother if you can. You have said your father is on SSI and Medicaid. That means your father has no money. You cannot be in those programs unless you have basically nothing. The state will have a lien on the home if/when he dies. It might not be worth the money or trouble to you or your father to go after your brother or to seek a guardianship. There is basically nothing to fight over. Think seriously about getting into a legal power struggle during your father's last days.
Although I am an attorney, some cases do not have a good legal solution. Take advantage of being close to your father and get some stories out of him. Studies show that of all the things parents leave behind, the stories are what people treasure more than money or possessions.
Best of luck to you.
I am not your lawyer. Any advice given through the Avvo site is for hypothetical purposes only, and does not create an attorney-client relationship. The advice is without warranty and you should not rely on this advice without consulting a Wisconsin attorney directly who knows the particulars of your case.
Both of the other attorneys' advice should be accepted; a court might not only appoint someone other than your brother as guardian and revoke the brother's POA authority, but might find your brother financially obligated.
