The divorce between rapper entrepreneur Dr. Dre (Andre Young) and his wife, Nicole Young, has recently take a turn for the contentious with news that Ms. Young has filed court papers that she signed a prenuptial agreement before their 1996 marriage under duress. What’s more, Young also claims that Dre ripped up the prenup documents three years into their marriage as a sign of his love, therefore rendering the terms unenforceable.
The former Mrs. Dre will need to provide evidence of her duress claims. But what about the idea that destroying the paper copy of a prenuptial agreement voids it? Is there any legal merit to this idea?
