Overview

South Dakota's financial services (credit card industry in Sioux Falls), agriculture, and tourism sectors rely on NDA protections as the primary means of safeguarding confidential information, given the state's restrictions on non-compete agreements.

This guide covers the key South Dakota laws that affect consulting agreements, the essential clauses your agreement should include, common drafting mistakes to avoid, and practical guidance for creating an enforceable consulting agreement under SD law.

Key South Dakota Laws Affecting Consulting Agreements

Several South Dakota laws directly impact how consulting agreements must be structured and enforced:

  • South Dakota Uniform Trade Secrets Act (SDCL § 37-29-1 to 37-29-11)
  • South Dakota Employment Law provisions
  • South Dakota Codified Laws Title 60 (Labor and Employment)

Non-Compete Enforceability: In South Dakota, non-compete clauses are generally void under SDCL § 53-9-8 through 53-9-12, with exceptions for sale of business or dissolution of partnership. This directly impacts how restrictive covenants should be drafted in any consulting agreement.

Statute of Limitations: South Dakota has a 6-year statute of limitations for written contracts under SDCL § 15-2-13.

Essential Clauses in a South Dakota Consulting Agreement

A well-drafted consulting agreement for South Dakota should include these critical elements:

  1. Scope of Consulting Services: Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  2. Compensation Structure (Hourly, Project, Retainer): Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  3. Independent Contractor Status and Classification: Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  4. Intellectual Property Ownership and Work Product: Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  5. Confidentiality and Non-Disclosure Provisions: Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  6. Term, Termination, and Transition Obligations: Ensure this section complies with applicable South Dakota law and clearly defines the rights and obligations of each party.
  7. South Dakota-Specific Compliance: Include express language confirming the agreement complies with all applicable SD statutes and regulations, and specify South Dakota as the governing law.
  8. Dispute Resolution: South Dakota Circuit Courts handle business disputes. The state enforces arbitration under the South Dakota Arbitration Act.

Common Mistakes to Avoid

When drafting consulting agreements for South Dakota, avoid these frequently encountered pitfalls:

  • Failing to clearly establish independent contractor status, risking misclassification
  • Not specifying who owns the intellectual property created during the engagement
  • Vaguely defining deliverables, leading to scope creep and payment disputes
  • Omitting confidentiality provisions for sensitive business information
  • Not addressing what happens to work product if the agreement is terminated early
  • Ignoring South Dakota-specific requirements: South Dakota has specific laws and judicial precedents that affect enforceability. Using a generic template without SD customization can result in unenforceable provisions.

Consideration and Enforceability in South Dakota

Standard contractual consideration applies. With non-competes largely void, robust NDAs are the key tool for protecting trade secrets.

For a consulting agreement to be enforceable in South Dakota, it must generally satisfy the basic requirements of contract formation: a clear offer and acceptance, adequate consideration, mutual assent, and lawful purpose. South Dakota courts may decline to enforce agreements with unconscionable terms or those obtained through duress or undue influence.

Frequently Asked Questions

In South Dakota, the distinction between a consultant (independent contractor) and an employee is determined by examining multiple factors including the degree of control over how work is performed, whether the worker provides their own tools and equipment, the permanency of the relationship, and the method of payment. South Dakota may apply the common law test, the ABC test, or an economic reality test depending on the context (tax, employment law, workers' compensation). Misclassification can result in significant penalties including back taxes, benefits, and fines. Consult a South Dakota-licensed employment attorney for guidance.

Under South Dakota law and federal copyright law, absent a written agreement, the consultant generally retains ownership of the work they create — even if the client paid for it — because independent contractors own their copyrights by default. A "work made for hire" provision typically does not apply to independent contractors except for certain categories. To ensure the client owns the work product, the consulting agreement should include an explicit intellectual property assignment clause. This is one of the most important provisions to include in any consulting agreement.

In South Dakota, non-compete clauses in consulting agreements are generally void under SDCL § 53-9-8 through 53-9-12, with exceptions for sale of business or dissolution of partnership. For independent contractors, courts may apply different standards than for employees. The clause must generally be reasonable in scope, duration, and geographic limitation. Standard contractual consideration applies. With non-competes largely void, robust NDAs are the key tool for protecting trade secrets. A non-solicitation clause (preventing the consultant from soliciting the client's customers or employees) may be a more enforceable alternative. Consult a South Dakota-licensed attorney to determine what restrictions are appropriate for your consulting relationship.
