Prenuptial agreements or premarital agreements serve an important function in any marriage. In short, they let couples clearly identify the property, assets or debts they are bringing into a marriage. Should divorce become a reality, this document provides a clear picture regarding nonmarital assets. Essentially, lawyers recommend having a prenuptial agreement in case the couple ultimately chooses to separate. A prenup can alleviate many hours of negotiation regarding what’s yours and what’s your spouse’s.
