President Donald Trump frequently touts his career spent making billions of dollars in real-estate deals, but he has a well-documented track record of cutting deals with his wives as well. 

With three marriages and two divorces under his belt, Trump is no stranger to prenuptial agreements, which lay out what each spouse will gain or lose in a divorce. 

"It's a hard, painful, ugly tool," Trump said after his third marriage. "Believe me, there's nothing fun about it. But there comes a time when you have to say, 'Darling, I think you're magnificent, and I care for you deeply, but if things don't work out, this is what you're going to get.'"

These contracts can include money, houses, or anything a future spouse deems valuable enough to protect. They can also be amended over the course of a marriage to match a spouse's growing wealth or growing family, and are often private until the terms shake out in a divorce settlement.

Over the course of their relationship, the couple had four prenups that were adjusted as their family and wealth grew.

After the marriage lasted over three kids and 13 years, the couple filed for divorce on December 11, 1990. It was reported that the last of the couple's four prenuptial agreements dictated the final divorce deal.
