A good prenup will do far more than simply protect the wealthier party from being taken to the cleaners in a divorce.  The document can and should provide some amount of financial security for the poorer spouse.  Without some baseline financial protections, we may worry about being left broke and homeless every time there is an argument.  Beyond being the right or nice thing to do, a fairly drafted PreNup will place it on a firmer foundation and render it legally stronger in the face  of an attack.  A totally one-sided PreNup, by contrast, may well be struck down by a Court as being “Unconscionable”.   Couples are increasingly customizing the document to deal with more than “who gets what in a split”.  Financial penalties for infidelity, social media limitations, and spending limits during the marriage are just a few of the customization options available to forward thinking couples.
