South Dakota alimony amount

Section 25-4-41 gives courts discretion to order a suitable allowance rather than a percentage formula.

When a divorce is granted, South Dakota Codified Law §25-4-41 allows the court to require one party to pay a suitable allowance for the other party's support for life or for a shorter period, as the court deems just in light of the parties' circumstances. [1]

The statute does not set a statewide percentage for amount or convert marriage length into a fixed duration schedule.

South Dakota alimony factors

South Dakota appellate law uses case-specific factors.

South Dakota decisions identify factors including marriage length, each party's earning capacity, financial condition after property division, age and health, station in life, and relative fault in the termination of the marriage. The factors guide judicial discretion rather than producing an automatic number. [2]

South Dakota modification

Current Supreme Court guidance focuses modification on changed financial circumstances.

In Peery v. Peery, the South Dakota Supreme Court reiterated that alimony determinations are reviewed for abuse of discretion and that modification turns on changed circumstances, including the recipient's necessities and the obligor's financial ability. [2]
