A bill becomes law if signed by the President or if not signed within 10 days and Congress is in session. If Congress adjourns before the 10 days and the President has not signed the bill then it does not become law (Pocket Veto.)
Amounts paid. or reasonably expected to be paid during estate administration are deductible on Form 706; or, executor can elect to. claim some administration expenses on Form 1041 when paid. On Form 1041, expense is subject to 2% adjusted gross.
Assuming this allocation is reasonable, you may deduct the fees for nonpersonal matters as long as the deduction amount exceeds the 2% floor. Tax deductibility of legal expenses in the estate planning context is not very clear and fraught with danger. Care should be taken before claiming the deduction.
