Thanks so much for the guidance.
1) Any problem with 2 family members witnessing my dad's "X" on the EVR?
Technicly a witness can not have an 'interest' in the signer
2) And how do I report the payments my dad receives from his LTC insurance policy that are used to partially defray the SNF monthly expenses?
you can only claim an expense that is NOT reimbused or paid by some one other than the vet so if the cost is 5000 and the ltc policy pays 3000, then you can only report $2000
3) This is my first EVR ... any less-than-obvious pitfalls to avoid?
What a marvelous website this is!!
