The South Dakota postnuptial agreement is a legal document created between two spouses for the purpose of defining their financial and non-financial relationship during and after the marriage.

The parties mostly use the postnuptial agreement form to determine how they will manage their individual and marital property during the marriage. However, they also use the document to determine how the property will be divided between the parties in case they get divorced.

There is a difference between postnuptial and prenuptial agreements. While the prenup agreement becomes valid from the moment parties get married, the postnup agreement is created when they have already entered the marriage.

Laws and Legal Requirements for a Postnuptial Agreement in South Dakota

The laws and legal requirements for a postnuptial agreement in South Dakota are all outlined in state laws and court decisions. The main reason for this is that South Dakota has not adopted the Uniform Marital Agreement Act.

One of the most important court cases for determining the legality of postnuptial agreements in South Dakota is In re Est. of Smid (2008). In this case, the court once again confirmed that “postnuptial agreements are subjected to close scrutiny because of the confidential relationship between husband and wife.”

This means that the court will have an additional level of scrutiny when determining the legality of the postnuptial agreement compared to other types of contracts.

The state law requires the parties to make their postnuptial agreement in written form. Moreover, the state law provides that both parties to the agreement must sign the document.

The notarization of the postnuptial agreement will additionally confirm the authenticity of the document and prevent potential disputes between the parties and any fraudulent activities in this regard.

Both parties must sign and execute the postnuptial agreement voluntarily. This means there should be no fraud, pressure, duress, coercion, or other means of manipulation of the spouses' will to enter the agreement.
