Under a 2019 separation agreement and divorce decree, Helen transfers a building (which is her separate property) to her ex-husband, Ken, in exchange for his release of any rights he has in other property that Helen acquired during the marriage. The transfer is made on the day of the divorce. Helen bought the building in 1996 for $1 million. Over the years, she made $200,000 worth of capital improvements in the building (using her separate funds). Its fair market value on the date she transfers it to Ken is $1.5 million. A week later, however, the market crashes, and Ken is forced to sell the building for $800,000.
