When it comes to the subject of prenuptial agreements, the important thing to remember is that everyone's situation is different. For some couples, they may have been married before and therefore come to their next marriage with a considerable amount of assets. For them, a prenuptial agreement is about protecting what they had in the event that divorce should strike twice. For others, the situation may be very different.
Take for example couples who are getting married for the first time. For couples in this situation, they wouldn't have a previous divorce to look back at and know what to do differently with their next marriage. As a result, first-marriage couples may not think about the usefulness of a prenup nor would they know how to enforce one if the situation arose.
