South Dakota Employment Contract Review
South Dakota is one of the few states that writes the limits of an employee non-compete into statute. SDCL 53-9-11 allows one for up to two years, within a specified county, city or other area, where the employer carries on a like business. Separate rules restrict non-competes for many healthcare practitioners, and the state's final-pay statute has an unusual link to returning company property.
Non-compete in South Dakota
Generally enforceable if reasonable
Typical enforceable duration: 2 years
Are non-competes enforceable in South Dakota?
Here is South Dakota non-compete law in plain English, with the statute it rests on.
Enforceable for up to two years within the area where the employer does business. Under SDCL § 53-9-11.2 a non-compete is voidable by listed health care practitioners (contracts from July 1, 2023) and by community services providers for people with developmental disabilities (contracts from July 1, 2026).
Whatever the label in your contract, South Dakota courts look at whether the restriction is reasonable in duration, geography, and scope. A nationwide, multi-year, whole-industry ban is far more likely to be narrowed or struck down than a narrow one.
Who owns what you invent in South Dakota?
South Dakota does not have a specific personal-invention carve-out statute, so a broad IP-assignment clause can reach more of what you create, potentially including side projects. Read the assignment scope and push to limit it to work actually related to your job.
Arbitration and class-action waivers in South Dakota
South Dakota generally follows the federal rule that arbitration agreements are enforceable. Before you sign, check whether the clause is mutual and whether it waives your right to a class or collective action, you are usually giving up the right to sue in court.
What does SDCL 53-9-11 actually allow?
An employee may agree not to engage directly or indirectly in the same business as the employer for up to two years after employment ends, within a specified county, first or second class municipality, or other specified area, as long as the employer carries on a like business there. A clause that names no area, or runs longer than two years, falls outside the statute.
Since 2021, SDCL 53-9-11.1 has limited non-competes for physicians and several other health providers, and a 2023 amendment extended the protection to a wider list of licensed practitioners for contracts entered on or after July 1, 2023. If you are a clinician, check the current list before signing.
When is your final South Dakota paycheck due?
Under SDCL 60-11-10 (employer-initiated separation) and 60-11-11 (resignation), wages are due by the next regular payday for the period worked, or as soon after that as you return all employer property in your possession. South Dakota does not require a payout of accrued vacation unless the employer's policy promises one.
Otherwise, South Dakota is a strongly at-will state. Its courts recognize a public policy exception for firings such as retaliation for filing a workers' compensation claim or refusing to commit a crime, and a handbook creates a for-cause promise only if it clearly limits the employer's right to terminate.

South Dakota employment contract FAQ
Are non-competes enforceable in South Dakota?
In South Dakota, a non-compete is generally enforceable if it is reasonable in time, geography, and scope. Enforceable for up to two years within the area where the employer does business. Under SDCL § 53-9-11.2 a non-compete is voidable by listed health care practitioners (contracts from July 1, 2023) and by community services providers for people with developmental disabilities (contracts from July 1, 2026).
Can my South Dakota employer own inventions I make on my own time?
South Dakota does not have a specific statute carving out personal-time inventions, so a broad IP-assignment clause can reach more of what you create. Read the assignment scope carefully and ask to limit it to work related to your job.
Do I have to sign a mandatory arbitration agreement in South Dakota?
South Dakota generally follows the federal rule that arbitration agreements are enforceable. Check whether the clause is mutual and whether it waives your right to a class action, and know that you are usually giving up the right to sue in court. Everywhere in the US, the federal Ending Forced Arbitration Act lets you take sexual harassment and sexual assault claims to court even if you signed one.
How long can a non-compete last in South Dakota?
Courts in South Dakota have treated 2 years as the outer edge of what is typically reasonable for an employee. Duration is only one factor: geography and the scope of restricted activity are weighed alongside it, and a term that is reasonable for a senior employee may not be for a junior one.
What if I work in South Dakota but my employer is in another state?
It matters, because South Dakota's neighbours do not all treat non-competes the same way: Minnesota (void), North Dakota (void), Wyoming (limited). Which state's law applies turns on the governing-law and venue clauses in your contract and on where the work is actually performed, so those two clauses are worth reading closely before you sign.
Does it help that Minnesota and North Dakota voids non-competes?
Only if that state's law actually applies to you. Living next to Minnesota or North Dakota does not import its rule into a South Dakota contract. What governs is the contract's choice-of-law clause and where you perform the work, which is exactly why those clauses deserve attention.
If a South Dakota non-compete is too broad, does it get narrowed or thrown out?
Courts may rewrite an overbroad restriction to something reasonable. That cuts against you: an employer has little to lose by drafting wide, because a court can pare the clause back rather than discard it. Negotiating the wording before signing matters more here than in states where an overbroad clause simply fails.
What else should I check in a South Dakota employment contract?
Beyond the non-compete: how invention assignment is worded and whether it reaches work done on your own time; whether disputes go to arbitration and whether class actions are waived; whether notice periods are symmetrical between you and the employer; and how any equity vests, including what happens if you leave before a cliff.
Can a South Dakota employer hold my final check until I return my laptop?
The statute ties the due date to returning employer property, so your last paycheck can be delayed until you hand back the laptop, badge or other items. It is a timing rule, not permission to deduct the value of unreturned property, and an employer cannot refuse returned property to hold wages indefinitely. Return items promptly and keep a receipt.
Does South Dakota's non-compete statute apply to sales representatives?
Yes, the general employee rule in SDCL 53-9-11 applies to employees of all kinds, including sales staff, unless a specific exception such as the healthcare practitioner rule applies. The two-year limit and the requirement of a specified area apply. Customer non-solicit clauses are often analyzed under the same section, so check their length and geography too.
