A post-nuptial agreement is generally a good idea for those who want to protect their assets during a marriage. A post-nuptial agreement is signed after you're already married, so both parties should be well aware of the assets and debts of the other person. A post-nuptial agreement can be of help during a divorce, because it will determine how those debts and assets are split.

For instance, in 2010, a law was created following a post-nuptial agreement-based case. The law now stands that post-nuptial agreements can be enforced, but the judge needs to be wary.
