South Dakota Power of Attorney vs. Guardianship: Key Differences

When a parent starts showing signs of cognitive decline, families face a fork in the road: set up a power of attorney now while capacity exists, or wait and petition for guardianship after it's too late. The difference between these two paths in South Dakota is thousands of dollars, months of delay, and a public court record versus a private document signed at a kitchen table.

The Fundamental Difference: Voluntary vs. Court-Ordered

A power of attorney is voluntary. The principal chooses their agent, defines the scope of authority, and signs the document while they still have mental capacity. No court is involved. No judge reviews the decision. The principal can revoke it at any time.

A guardianship (for personal decisions) or conservatorship (for financial management) is court-ordered. Under SDCL 29A-5, a family member or interested party petitions the South Dakota Circuit Court after the person has already lost capacity. A judge determines whether the person is incapacitated, appoints a guardian or conservator, and supervises their actions going forward.

Cost Comparison

Power of attorney: The cost of drafting and notarizing a POA in South Dakota ranges from the cost of a downloadable template to $250-$350 for attorney-drafted documents. Notarization is typically free at most banks.

Guardianship/conservatorship: The court filing fee is approximately $72. But legal fees are the real cost — attorney representation for the petitioner, the court's appointment of a guardian ad litem or attorney to represent the proposed protected person, and the petition hearing itself. Total costs commonly range from $1,500 to $5,000 or more, depending on whether the petition is contested.

And guardianship costs don't stop at appointment. The guardian must file annual reports with the court, and the conservator must provide detailed financial accountings. Each filing cycle may require additional attorney time.

Timing

A POA can be completed in a single day — drafting, signing, notarizing, and distributing copies to banks and healthcare providers.

A guardianship petition in South Dakota requires:

1. Filing the petition with the circuit court
2. Serving notice on the proposed protected person and all interested parties
3. A court hearing (typically scheduled weeks after filing)
4. The court's determination of incapacity
5. Appointment of the guardian or conservator

From petition to appointment, the process typically takes four to eight weeks at minimum. If contested by family members, it can stretch to months.

Privacy

A POA is a private document. No public record is created unless the document is recorded with the county register of deeds for real estate purposes.

Guardianship proceedings are filed with the circuit court and become part of the public record. The petition, medical evaluations, financial disclosures, and the court's determination of incapacity are all accessible. For families, this public declaration of a parent's incompetence can feel degrading and invasive.

How They Interact

Under SDCL 59-12-7, a principal can use their financial POA to nominate a preferred conservator or guardian. If the court later initiates protective proceedings, it must generally follow the principal's nomination unless there's good cause to deviate.

If a conservator is appointed for someone who already has a financial POA, the agent's authority does not automatically terminate. The agent remains accountable to the conservator, and the conservator can direct the agent's actions — but the court must explicitly limit or terminate the POA if it wants to remove the agent's authority.

For healthcare POAs, the interaction is different. Under SDCL 59-7-11, if a court appoints a guardian of the person, the healthcare POA terminates automatically at the moment of appointment. However, the guardian is legally required to follow the medical treatment preferences documented in the terminated POA.

When Guardianship Is Unavoidable

A POA is only an option while the principal still has mental capacity to sign. Once capacity is lost, guardianship is the only path. Common scenarios where families end up in court:

• A sudden medical event (stroke, severe accident) with no POA in place
• Advanced dementia diagnosed before any planning was done
• The existing POA agent is unable, unwilling, or suspected of abuse
• Family members dispute who should make decisions

The best protection against a forced guardianship is a durable POA executed while the principal is still competent. The South Dakota Power of Attorney Kit includes both financial and healthcare documents with guardian nomination provisions under SDCL 59-12-7.
