Pre-nuptial and post-nuptial agreements include all sorts of things these days, and they certainly are no longer just for the wealthy. Would you agree to get married, if it also meant you agreed to be skinny or to be intimate with your spouse on a certain schedule? Pre-nuptial agreements include all sorts of things these days, and they are super rich. In fact, 73 percent of divorce lawyers surveyed by the American Academy of Matrimonial Lawyer in 2010, report pre-nups are up in the last five years. The same group reports that 51 percent of divorce lawyers surveyed in 2012, said they've seen an increase in post-nuptial agreements over the past three years. Lilly, Newman and Van Ness (LNVN) , a large Houston family law firm, does four times as many pre-nups as they did a decade ago.
