Divorce in South Dakota: Laws, Process, and What You Need to Know (2026)

South Dakota has one of the shorter waiting periods for divorce and allows both fault and no-fault grounds. The state uses equitable distribution and its courts have broad discretion in dividing property, considering both the length of the marriage and each party's contributions.

Residency Requirements

To file for divorce in South Dakota, you must meet the state's residency requirements: Residency at the time of filing. This means at least one spouse must have lived in South Dakota for the required period before the court will accept a divorce filing. You will typically file in the county where either spouse resides.

Grounds for Divorce

South Dakota allows both no-fault and fault grounds for divorce. No-fault: irreconcilable differences. Fault grounds include adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance, and felony conviction. While most divorces proceed on no-fault grounds, filing on fault grounds can sometimes affect alimony or property division outcomes.

Property Division

South Dakota follows the equitable distribution approach to dividing property in a divorce. Under this system, the court divides marital property fairly, though not necessarily equally. The judge considers factors like each spouse's economic circumstances, contributions to the marriage (including homemaking), the duration of the marriage, and any dissipation of assets.

Property that either spouse owned before the marriage, as well as gifts and inheritances received individually, is generally considered separate property and is not subject to division. However, if separate property has been commingled with marital assets, it may lose its separate character.

Alimony and Spousal Support

The court considers several factors when determining alimony in South Dakota:

Length of marriage
Earning capacity
Financial condition
Age and health
Standard of living
Fault of either party

South Dakota courts have broad discretion to award alimony, which may be temporary or permanent. Fault may also be a consideration in the award.

For a comprehensive overview of alimony types and negotiation strategies, see our alimony and spousal support guide. The duration and amount of alimony depend heavily on the length of the marriage and the financial circumstances of both parties. Short-term marriages are less likely to result in long-term alimony awards.

Child Support

South Dakota uses the Income Shares model for calculating child support, based on both parents' net income and the number of children.

See our child support guide for a detailed explanation of calculation models and modification rules. Either parent can request a modification of child support if there is a substantial change in circumstances, such as a significant change in income, job loss, or a change in the child's needs.

Child Custody

South Dakota courts determine custody based on the best interests of the child standard. The court evaluates a range of factors including each parent's relationship with the child, the child's adjustment to home and community, the mental and physical health of all parties, and the willingness of each parent to foster a relationship between the child and the other parent.

Most states, including South Dakota, recognize both legal custody (decision-making authority regarding education, healthcare, and welfare) and physical custody (where the child lives). Both types can be awarded jointly or solely to one parent.

Mediation

Mediation is not required in South Dakota, though it is often encouraged.

Filing Fees and Costs

Filing fees for divorce in South Dakota typically range from $95-$150, though exact amounts vary by county. Additional costs may include:

Attorney fees (if you hire a lawyer)
Mediation or alternative dispute resolution fees
Process server or publication fees
Costs for financial experts or appraisers (in complex asset cases)
Court-mandated parenting class fees (if children are involved)

Uncontested divorces are generally significantly less expensive than contested cases.

Key Considerations

Standard process: South Dakota follows a conventional divorce process with no unusual procedural requirements.

If you and your spouse can agree on the major issues, including property division, support, and custody, an uncontested divorce will save you significant time and money. Even in contested cases, exploring mediation or collaborative divorce may lead to a better outcome than a courtroom battle.
