Will I get my money back from paying moms bills after she dies?

First question: Can you tell creditors that mom died and you have to wait for the money cause the bank froze the accounts?
Brother has Life Deed for home. He is on SSI and gets food stamps. Mom was scared he would be homeless. Said the house isn't worth enough to pay for condo or rent for brother. He is only 53. Plus he wanted to continue to live jn house so mom made sure he could. He was thrown out if subsided apartment. Didnt pass inspection. Waiting list to get back in subsiduzed apartment is years long. Mom wrote a special needs trust. I run it.

my moms house was left to my sister . im fine with that cause i dont want it but i can tell you the utilities were killed within hours of moms passing away .
if someone cant pick up the utilities on a free house and property they can sit in the dark for all i care .

Usually the Executor pays the bills from whatever funds are in the estate, which includes the house.... you do NOT use your own money. Will selling the old piano and the silverware bring in enough to pay the bills? If not, maybe the house needs to be sold to pay off the bills.

Just because your brother inherits the house, it doesn't mean he gets the house free for life. Does he want to continue to live in the house? If so, have him refinance the house and pull out equity to use to pay the bills. As for next month's utilities, house insurance, property taxes, those bills now belong to your brother.
