It’s all over the news lately that Prince William and his fiancé Kate Middleton will likely not sign a prenuptial agreement before the royal wedding on April 29th. Although many reasons have been given as to why the couple will forgo signing a prenup, one of the reasons is that “while prenuptial agreements are common in the United States, they are far less prevalent in the UK. Only in the last year have British courts agreed to recognize such deals.” This is a statement that has some Americans asking exactly how legally binding are prenuptial agreements here in the States?

The answer to that question depends on a number of factors: your state of residence, the terms of your prenuptial agreement, how long you stay married, and more.  Fortunately, the longer prenuptial agreements are around, and the more common they become, the more respect they get from the courts.  But if you’re worried that your prenuptial agreement won’t hold up in court, here are few tips to help ensure the validity of your agreement.

The agreement should include full disclosure of income and assets. If you live in a state where it is possible to waive full disclosure of assets then BOTH parties should specify that they do so knowingly.

Each party should have their own legal representation. In order to be sure that neither party is being taken advantage of, each party should have their own independent attorney review the document before it is signed.
