We know conversations about prenups can be difficult to have. The earlier you have it, though, the better. Do not wait until the last minute. Besides the significant time it can take to get prenups prepared and executed, if the first time the other person learns that you want a prenup is near your wedding day, it may make them feel like they are being given an ultimatum. And, legally, should you hurry through the prenup process and the marriage ends, your spouse may challenge the prenup by claiming they were rushed or coerced into signing.
