A marriage agreement, also known as a Prenuptial Agreement, is a written agreement between spouses that regulates their rights and obligations. The agreement can be made before or after the marriage.

The purposes of a marriage agreement are:
1. To keep each spouse's wealth separate.
2. To ensure the smooth operation of a business, where if one spouse goes bankrupt, the other spouse's assets will not be seized.
3. To allow spouses to establish a limited liability company together without involving third parties.
4. To release one spouse from the obligation to pay the other spouse's debts.
5. To ensure the orderly distribution of family inheritance.
