How South Dakota Divides Property

South Dakota uses equitable distribution as its default property system — assets are divided fairly but not necessarily 50/50, based on each spouse’s income, contributions, and earning potential. South Dakota also offers an optional community property trust, allowing couples to elect community property treatment for specific assets. A prenup can define your own property rules, overriding the default equitable distribution framework.

How Clause Helps

Your Clause prenup explicitly defines which property is separate and which is marital, overriding South Dakota's default equitable distribution rules with terms you both agree on.
