Investors & landlords

Hi, Critter thanks for the detail in your discussion.  I want to file SHH because my ex-spouse and I can't agree on how to split the joint return and I am willing to take a lower return (penalizing both of us) since ex-spouse is being unfair.  Is there a way for me to report only my half of the capital gains from the sale of our house when filing SHH?  I do not live in a community property state, I am in Colorado.
