Are there any rules for negotiation in divorce?

“Maybe if I can’t afford this house and I have to sell it in two years and it’s all on me, I only get the exclusion up to $250,000, whereas if we sold it as a couple, we could have had a $500,000 exclusion and saved ourselves a lot more in profit.” – Lili Vasileff in re: discussion of tax smart asset division tips for divorce.
