While living, Schemer promised Spouse that if Spouse would be kind and loving, Schemer would leave Spouse $400,000 of Schemer's $1 million estate; but Schemer did not. What is the result if Schemer's promise was made in a separation agreement with Spouse and was a promise binding on Schemer's estate becoming effective on Schemer's death to pay Spouse $10,000 per year until Spouse died or remarried for a relinquishment of Spouse's right to support? What is the result in the above question if Spouse remarried on the day of Schemer's funeral, a few days after Schemer's death? Would that affect the amount of the estate tax deduction?
