After my dad passed, my brother lied and said he had filed a probate case. In the meantime, he moved into the family home and began running up debt with the utility companies and God only knows how much money he may have put on Dad's charge cards. Now its 3 1/2 years later and I have filed with probate and am the personal representative. Who is liable for the electric bill? And what if I do discover charges made following Dad's death?
