Woman on a staircase looking gloomy.
  • I got married in 2008 and, thanks to my mom, signed a prenup to protect my inheritance. 
  • The prenup said my husband couldn't use the money to pay for school.
  • We used the money for a house, and I learned that my prenup didn't protect me from having to split that 50-50. 

This is part of our series Splitting the Difference, which examines the financial lives of couples.

Never forget that marriage was originally intended to be a business relationship between two men in power: the bride's father and the husband-to-be.
