Only creditors of your wife's grandmother can file claims against her estate. All of grandmother's debts must be paid before her assets can be distributed. The assets distributed to her son, your wife's father, would be susceptible to attachment by the IRS. As an executor of the estate the father does not personally own any assets of the estate and thus the IRS would not be able to lien , attached or execute a claim against such assets for his personal debts. Your wife's father may be able to disclaim any distribution from grandmother's estate, in which case the assets would be distributed as if the father predeceased his mother. You should consult with an attorney.
