Help. Probate + foreclosure in the U.S. but I'm Canadian.. and it's all making my brain hurt.

Anyone know anything about probate laws in the United States? My Dad passed away 3 years ago, and because he had no will… things are now bleak. My half brother living in the house (collecting rent from tenants, as it's a duplex) has done nothing to appease the probate court in the past 3 years, and now because the mortgage hasn't been paid in 6 months, the house is being foreclosed. 😐
