With singer Joe Jonas and actor Sophie Turner announcing an "amicable" divorce Wednesday, an apparent prenuptial agreement will ensure that they won't have to fight over how to split their wealth. "I would absolutely advise having an attorney draw up an ironclad prenuptial agreement," says Crystal Cox, a certified financial planner in Wisconsin. "I always say you have a prenuptial agreement one way or another, the only difference is whether you decide the terms or if you let the state decide." How prenups workA prenuptial agreement is a legally binding contract made between two people before they get married. There are all sorts of reasons to sign a prenuptial agreement even if you aren't rich, says Scott Bishop, a CFP in Houston.
