Washington, October 26  : Kim Kardashian and Kanye West have decided to sign a prenuptial agreement and keep their assets separate.

Sources revealed that the 36-year-old rapper and his 33-year-old fiance are committed to the marriage and have agreed to sign a prenup as they are both business people and believe that it's the smart thing to do, TMZ reported.

Sources added that the reality star understands the importance of the agreement as her father, Robert Kardashian, had told her over and over about the necessity of having clear contracts when it came to money.

Though the couple will keep their assets separate, they will have a joint account for living expenses.

According to reports, West is valued at 90 million dollars and Kim's wealth is approximately 40 million dollars, but it is believed that she is worth more than him. (ANI)
