Executor’s Exposure To Decedent Spouse’s Tax Liability

My client’s spouse passed away last year with a significant tax liability due to IRA withdrawals. I’m concerned about my client’s personal liability due to being executor and personal representative of the estate. We submitted a request for relief under Revenue Proclamation 2013-34 and plan to file form 56 & Form 5495. Should we do anything else to protect our client from the decedent spouse’s tax liability?
