What does a prenuptial agreement protect you from?

A prenuptial provides protection for the party bringing a greater share of the assets to the marriage. If the marriage breaks down, they could potentially lose 50% or more of that asset. It allows the wealthier party to retain control of their assets and personal possessions.

This also potentially applies to future assets, such as inheritance from a loved one or growth of a business, although the latter can be problematic if the marriage lasts a long time. Finally, it can protect children from another relationship, as it can preserve their potential inheritance.
