Can an estate bank account be levied?

I am the administrator for a deceased relative who had no will, no assets and bank accounts had been levied. I received a rent deposit check in the deceased name after closing out the apartment. As the administrator, I tried to deposit the check in my account so that I could pay off funeral expenses but was told that I have to create an estate account. This is the only amount of money I have for this relative and paying the funeral expense will be the only transaction. Do I really need to establish an estate account for that? Also, can the estate account be levied because of the debts owed by my relative? I fear this money will simply be levied as with the relatives other accounts and I will have to scrape more money together for funeral expenses.
