10 South Dakota Divorce Mistakes to Avoid (2026)

Mistake #1 — Filing Without a Complete Separation Agreement

South Dakota files the Separation Agreement with the Complaint. Filing a Complaint without a completed, signed, and notarized Separation Agreement will delay your case and may require re-filing.

Fix: Negotiate and fully execute the Separation Agreement before filing the Complaint. Draft it carefully — it controls the outcome of every issue.

Mistake #2 — Confusing Domicile with Temporary Presence

South Dakota requires current domicile — not just physical presence. If you moved to South Dakota temporarily (for work, school, or another short-term reason), you may not satisfy the domicile requirement.

Fix: Confirm that South Dakota is your true, permanent home — where you intend to remain indefinitely. Establish local ties: driver's license, voter registration, permanent address.

Mistake #3 — No Refinancing Deadline for the House

If one spouse keeps the home, the other remains liable on the mortgage until it is refinanced. Without a deadline in the Separation Agreement, there is no mechanism to force refinancing.

Fix: Include a specific refinancing deadline (90–180 days after Decree) and a fallback sale provision. This is one of the most important protections in any divorce involving real estate.

Mistake #4 — Failing to Record the Deed at the Register of Deeds

The Separation Agreement or Decree alone does not transfer legal title to real property. The deed must be recorded.

Fix: After the Decree, prepare a Quitclaim Deed, execute and notarize it, and record it with the South Dakota Register of Deeds in the county where the property is located.

Mistake #5 — Skipping the QDRO

The Decree does not automatically transfer employer retirement plan benefits. A separate QDRO is required for each employer plan.

Fix: After the Decree, work with a QDRO specialist. For South Dakota state employees, contact the South Dakota Retirement System (sdrs.sd.gov) for DRO procedures.

Mistake #6 — Not Documenting Separate Property

South Dakota courts have broad equitable discretion. Even property that should be separate can be divided if it has been commingled with marital assets or if equity demands it after a long marriage.

Fix: Keep separate property in dedicated accounts. Document all origins with paper trails. List every piece of separate property explicitly in the Separation Agreement with acknowledgment from both parties.

Mistake #7 — Underestimating Fault's Role

Unlike many states, South Dakota courts may consider marital fault when dividing property and awarding alimony. Ignoring this can lead to unexpected outcomes.

Fix: If fault is relevant (adultery, extreme cruelty, etc.), consult an attorney to understand how it may affect property division and alimony in your specific case.

Mistake #8 — Not Addressing All Marital Debts

Your Separation Agreement does not bind creditors. If your ex defaults on a joint debt, the creditor can still pursue you.

Fix: List every marital debt in the Separation Agreement with creditor, account number, balance, assignment, and indemnification language. Refinance joint debts into the responsible party's name where possible.

Mistake #9 — Relying on the $95 Fee as the Total Cost

While the $95 filing fee is very low, additional costs (QDRO drafting, deed recording, appraisals) can add significantly to the total.

Fix: Budget for the full picture: QDRO ($500–$2,000 per plan), deed recording ($10–$30), possible appraisal ($300–$600), and any attorney fees for document review.

Mistake #10 — Not Updating Beneficiary Designations

The Decree does not automatically change beneficiary designations on life insurance, retirement accounts, or payable-on-death accounts.

Fix: Update all beneficiary designations immediately after the Decree is entered.
