While living, Schemer promised Spouse that if Spouse would be kind and loving, Schemer would leave Spouse $400,000 of Schemers $1 million estate; but Schemer didnt.

A) Is Spouses claim against Schemers estate deductible under Section 2053?

B) What is the result if Schemers promise was made in separation agreement with Spouse, and was a promise binding on Schemers estate and becoming effective upon Schemers death, to pay Spouse $10,000 a year until Spouse died or remarried for a relinquishment of Spouses rights to support?

C) What is the result in questions (B), above, if Spouse remarried on the day of Schemers funeral, a few days after Schemers death? Would that affect the amount of the deduction?
