AI for solo lawyers in South Dakota

Solo and small-firm lawyers in South Dakota are using AI to draft and review contracts faster. Unlike many states, South Dakota has not published an ethics opinion specifically on generative AI. That does not mean there are no rules: the South Dakota Rules of Professional Conduct apply to AI like any other tool, and ABA Formal Opinion 512 is the obvious reference point. This guide covers what applies, the South Dakota contract issues worth checking, and a practical workflow in Microsoft Word with LexDraft.

Is there a South Dakota ethics opinion on AI?

Not yet, as of October 2026. We could not find an ethics opinion on generative AI from the State Bar of South Dakota. Its most recent published ethics opinions deal with other topics.

Until there is, three sources set the standard for South Dakota lawyers:

• The South Dakota Rules of Professional Conduct. South Dakota's rules are based on the ABA Model Rules, so the duties of competence (Rule 1.1), communication (Rule 1.4), reasonable fees (Rule 1.5), confidentiality (Rule 1.6) and supervision of lawyers and nonlawyer assistance (Rules 5.1 and 5.3) all reach AI use. Check the South Dakota version of each rule and its comments, which can differ from the Model Rules.
• ABA Formal Opinion 512 (July 2024). It is not binding in South Dakota, but it is the most detailed national guidance. In short: understand the capabilities and limits of the tool you use; assess the risk before entering client information into a self-learning tool and get informed consent where that risk requires it; tell clients about AI use when the circumstances call for it; verify output; supervise staff who use AI; and do not bill for time you did not spend. Charging for learning a general-purpose tool is generally not appropriate.
• Court rules and standing orders. Some federal and state judges require disclosure or certification of AI use in filings. Check the local rules and the assigned judge's standing orders before you file anything drafted with AI help. Lawyers around the country have been sanctioned for filing briefs with invented citations.

Practical rules for a South Dakota solo practice

• Read the vendor's terms. Know whether your inputs are stored, for how long, and whether they are used to train models.
• Keep a short written AI policy, even for a one-lawyer firm, and apply it to any staff or contract help.
• Verify every output. AI review can miss issues or be wrong.
• Consider an engagement letter sentence on AI use, and price AI-assisted work fairly. Flat fees fit it well.

South Dakota contract issues to check on every review

• Non-competes: SDCL 53-9-8 voids contracts restraining a lawful profession, trade or business, except as the statutes allow. Under SDCL 53-9-11 an employee may agree not to compete, or not to solicit existing customers, for up to two years after termination within a specified county, municipality or area. Non-competes with listed health-care practitioners entered into on or after 1 July 2023 are voidable (SDCL 53-9-11.2).
• Construction indemnity: SDCL 56-3-18 voids clauses in construction contracts that indemnify a party against its sole negligence.
• The limitation period for contract actions, generally six years (SDCL 15-2-13).
• Limitation of liability, indemnity and venue clauses in services agreements.

A contract review workflow for a South Dakota solo practice

LexDraft is a Word add-in from Microsoft AppSource. It opens as a side panel in Word 365 (Windows and Mac), Word 2021 and Word on the web, so the contract never leaves the tool you already draft in.

1. Open the contract in Word and open LexDraft in the side panel.
2. Set the job. For an NDA, SaaS MSA, DPA or services agreement, use the matching built-in playbook. For other contracts, select South Dakota and run the review so LexDraft looks for state-specific red flags.
3. Triage by severity. Findings are graded Critical, High, Medium or Low, and LexDraft flags standard terms that are missing.
4. Run the quick checks. The defined-term and cross-reference checks are rule-based and run without AI.
5. Accept or reject each redline. Accepted changes land as native Word tracked changes, ready for the other side.
6. Verify and sign off. You, as counsel, check every output before it goes out, which is what the rules of professional conduct require.

What LexDraft does not do

LexDraft does not give legal or ethics advice, track bar opinions for you, or file anything with a court. It has playbooks for NDAs, SaaS MSAs, DPAs and services agreements only; other contracts get a general review. Nothing changes in your contract until you accept a redline.

Checklist: choosing an AI tool

• Does it train on your client documents? LexDraft does not use customer documents to train models. Read the security page for how documents are handled.
• Can you see and control every change? LexDraft proposes word-level redlines you accept or reject.
• Is the price predictable? The Free plan has 5,000 generated words a month with no time limit and no credit card. Professional is $99 a month or $990 a year for 100,000 words. Business is $199 a month or $1,990 a year with unlimited words.
• Does it fit how you already work? A Word add-in means no uploads, no new editor and no copy-paste between apps.
