South Dakota Maintenance Case Law Examples

Moen v. Moen (2026)

In a recent 2026 decision, the South Dakota Supreme Court affirmed the denial of spousal support where the recipient had sufficient assets and income from property division and employment to meet needs independently. The court reiterated that need is the foundational requirement under SDCL 25-4-41, and maintenance is not a punitive tool.

The Supreme Court affirmed reduction of husband's alimony from $13,500 to $6,000 per month after a substantial good-faith decrease in income. The court denied retroactive modification, reinforcing that modifications are prospective only and require a substantial change in circumstances.

Hanson v. Hanson (2018)
