I don't know of many banks that make mortgage loans to trustees.  The house is usually deeded to the trust only after the purchase and financing are closed.  So the original deed and mortgage probably says the owners are "Aunt Jones and Nephew Jones."  Then they deeded it to "The Aunt Jones Trust," with Aunt Jones as Trustee and Nephew Jones as Successor Trustee.  The trust by now should have its own EIN.  The sale will be reported on the Form 1041 he should file. When you say the other beneficiaries don't want him to have any personal liability, do you mean tax liability?  Has the house increased in value since she died?  (Many Arizona homes have gone up 20% or 30% in the last year.)  He's responsible as Trustee for paying any taxes owed by the Trust.  Also owed by her, before she died, if he makes distributions to beneficiaries before paying IRS.
