Power of Attorney in South Dakota (2026)
A financial power of attorney in South Dakota must be notarized and needs no witnesses. You must be at least 18 years old and of sound mind when you sign it. Powers of attorney in South Dakota are durable by default, so the document stays in force if you later become incapacitated. South Dakota also allows a springing power of attorney, which takes effect only once you can no longer act for yourself.
Giving someone else control of your money sounds terrifying. Here's how South Dakota makes sure it doesn't go sideways.

Requirements

Durable vs. springing
In South Dakota, powers of attorney are durable by default, meaning they survive your incapacity unless you specifically say otherwise. This is actually the smart default for once.
South Dakota allows springing powers of attorney, which only kick in when you become incapacitated. Think of it as a legal “break glass in case of emergency” clause.
What your agent can do
Your agent (the person you pick) can handle banking, pay bills, manage investments, deal with real estate, file taxes, and handle insurance claims. Basically everything financial that you’d rather not think about, especially from a hospital bed.
Why this matters in South Dakota
Without a POA, South Dakota courts decide who manages your finances through a conservatorship proceeding. This costs thousands in legal fees under S.D. Codified Laws §29A-2-502, takes weeks or months, and the court might not pick the person you’d choose. All because you didn’t sign a piece of paper.
