I must admit that it has been a year or two since I had to file a 706 - but based upon your post I would say that the insurance proceeds from the VA would not have to be included on the return. All assets that a decendent had "incidents of ownership and control over" are included in the gross taxable estate of a decendent. If he could not change a beneficiary, assign the policy, cash in the policy, take a loan out against the policy - then he would not have incidents of owernship and control over the policy and as such the proceeds should not be included on the 706. In any event I assume the death benefits are not that much - by the way are you also an attorney?
good luck
