Introduction
Montana Code Annotated Section 28-2-703 voids any contract restraining a lawful profession, trade, or business, subject only to narrow exceptions for the sale of a business's goodwill and for partnership dissolution, yet since Dobbins, DeGuire and Tucker v. Rutherford in 1985 the Montana Supreme Court has enforced non-compete provisions that are reasonable in time and place, supported by real consideration, and that protect the employer without placing an unreasonable burden on the employee or the public. A Montana NDA is otherwise an ordinary, enforceable confidentiality contract, mutual or one-way, in which the parties agree to keep specified information secret. Trade secrets exchanged under an NDA are separately protected by the Montana Uniform Trade Secrets Act (Montana Code Annotated Sections 30-14-401 through 30-14-409), and a misappropriation claim generally must be filed within three years of when the misappropriation was discovered or reasonably should have been discovered. Montana has no statute carving an employee's own-time inventions out of an assignment clause, unlike California, Delaware, Illinois, Kansas, Minnesota, North Carolina, Utah, and Washington, so invention ownership in a Montana employment relationship runs on common law and whatever the agreement itself says. The practical effect for drafting is that a Montana NDA's confidentiality definition can safely run broader than a California one before it risks being struck down, though a clause that functions as an actual non-compete still has to satisfy the reasonableness test Montana courts apply to any restraint on someone's ability to work.
Key Things to Know
- 1
Trade secret protection runs through the Montana Uniform Trade Secrets Act (Montana Code Annotated Sections 30-14-401 through 30-14-409), separate from whatever the NDA itself says.
- 2
Montana Code Annotated Section 28-2-703 voids a contract restraining a lawful profession, trade, or business in almost the same words as California's non-compete ban, but Montana courts read it the opposite way. Since Dobbins, DeGuire and Tucker v. Rutherford (1985), a non-compete is enforceable here if it is limited in time or place, supported by real consideration, and reasonable for the employer without unduly burdening the employee or the public.
- 3
That reasonableness test applies to any restraint embedded in a Montana NDA, including an overbroad confidentiality clause that functions like a non-compete. An NDA that protects genuine trade secrets and sensitive information without reaching into what someone can do for a living afterward does not need to fit within Section 28-2-703's narrow express exceptions for selling a business's goodwill (Section 28-2-704) or dissolving a partnership (Section 28-2-705).
- 4
Montana separately bans non-compete restrictions outright for licensed health care providers, including physicians, nurses, physician assistants, psychologists, social workers, counselors, and other Title 37 licensees (Montana Code Annotated Section 28-2-724), so an NDA involving a health care professional cannot rely on the general reasonableness test the way other Montana NDAs can.
- 5
A trade secret misappropriation claim in Montana generally must be filed within three years of when the misappropriation was discovered or reasonably should have been discovered, and a continuing misappropriation counts as a single claim rather than a new one each time (Montana Code Annotated Section 30-14-407).
- 6
Montana has no statute requiring an employer to carve an employee's own-time, own-resources inventions out of an assignment clause, unlike California, Delaware, Illinois, Kansas, Minnesota, North Carolina, Utah, and Washington. Invention ownership in a Montana employment relationship runs on common law and whatever the agreement itself says.
- 7
Mutual NDAs, where both sides share confidential information, and one-way NDAs, where only one side does, are both ordinary enforceable contracts in Montana; which one fits depends on whether the exchange runs both directions, like a partnership or acquisition discussion, or one direction, like pitching an investor.
- 8
A Montana court can order injunctive relief to stop an ongoing or threatened misappropriation of a trade secret, in addition to damages, and the injunction lasts only as long as the trade secret advantage itself does (Montana Code Annotated Section 30-14-403).

Montana Requirements for Non-Disclosure Agreement
Clearly defines what constitutes confidential information under Montana law, including trade secrets as defined in the Montana Uniform Trade Secrets Act.
Specific provisions addressing the protection of trade secrets in accordance with Montana's adoption of the Uniform Trade Secrets Act, including remedies for misappropriation.
Includes required notice of immunity under the federal Defend Trade Secrets Act for individuals who disclose trade secrets in confidence to government officials or attorneys solely for the purpose of reporting or investigating suspected legal violations.
Acknowledges federal protections against theft of trade secrets, including criminal penalties that may apply to violations of the NDA.
Ensures the NDA meets Montana's essential elements of a valid contract: identifiable parties capable of contracting, their consent, a lawful object, and sufficient cause or consideration.
Explicitly states the consideration provided in exchange for confidentiality obligations, as required for contract validity under Montana law.
Section 28-3-102 sets Montana's choice-of-law default for contract interpretation (the law of the place of performance, or the place made if none is stated), and Section 25-2-118 sets the state's default civil venue rule based on a defendant's residence.
Provides for injunctive relief in case of breach, consistent with Montana's preliminary injunction standard requiring a likelihood of success on the merits, a likelihood of irreparable harm, and a balance of equities favoring the moving party.
Acknowledges the validity of electronic signatures in accordance with both Montana's Uniform Electronic Transactions Act and the federal ESIGN Act.
Informs parties of the applicable statute of limitations for breach of written contracts in Montana, which is 8 years from the date of breach.
Ensures any restraint embedded in the NDA satisfies the reasonableness test Montana courts apply under Dobbins, DeGuire and Tucker v. Rutherford, 218 Mont. 392, 708 P.2d 577 (1985), reaffirmed in Junkermier v. Alborn (2016): limited in time and place, supported by real consideration, and not unduly burdensome to the restrained party or the public. Section 28-2-724 separately and categorically bars this kind of restraint for licensed health care providers.
Addresses conditions under which confidential information may be disclosed to third parties, such as employees or agents, consistent with Montana's agency law defining an agent as one who represents a principal in dealings with third persons.
Ensures the handling of personal information complies with applicable federal privacy laws such as HIPAA, GLBA, or COPPA if relevant to the disclosed information, and with Montana's own Consumer Data Privacy Act, effective October 1, 2024 and amended effective October 1, 2025, when the confidential information includes Montana residents' personal data.
Provides procedures for handling situations where disclosure is required by law, court order, or governmental authority, consistent with Montana's subpoena rule, including notice requirements to the disclosing party.
States that the NDA constitutes the entire agreement between the parties regarding confidentiality, consistent with Montana's parol evidence rule for written agreements.
Frequently Asked Questions
A Non-Disclosure Agreement in Montana is an ordinary contract in which one or both parties agree to keep specified information confidential. It can be mutual, where both sides share confidential information, or one-way, where only one side does. Trade secrets shared under the agreement are also separately protected by the Montana Uniform Trade Secrets Act (Montana Code Annotated Sections 30-14-401 through 30-14-409) regardless of what the NDA itself says.
Generally yes, more so than in a state like California. Montana Code Annotated Section 28-2-703 voids contracts restraining a lawful profession, trade, or business in almost the same words as California's ban, but Montana courts do not read it as a categorical prohibition on non-competes. Since Dobbins, DeGuire and Tucker v. Rutherford (1985), a non-compete or a confidentiality clause with non-compete effect is enforceable in Montana if it is limited in time or place, supported by real consideration, and reasonable for the employer without imposing an unreasonable burden on the employee or the public.
Montana Code Annotated Section 28-2-703 and California Business and Professions Code Section 16600 both descend from the same nineteenth century Field Civil Code text and use almost identical wording voiding contracts that restrain a lawful profession, trade, or business. California courts, along with Oklahoma and North Dakota, read their version as a near categorical ban on non-competes. Montana courts instead apply a common-law reasonableness test from Dobbins, DeGuire and Tucker v. Rutherford (1985), enforcing a restraint that is limited in time or place, supported by consideration, and not unduly burdensome. A Montana NDA can therefore embed a working non-compete provision that a California NDA generally cannot.
Yes, for licensed health care providers. Montana Code Annotated Section 28-2-724 voids a provision restricting a health care provider, including physicians, nurses, physician assistants, psychologists, social workers, counselors, and other licensed professionals, from practicing after the relationship ends, with exceptions for practice-sale agreements and declining loan or relocation repayment terms. Outside health care, Montana's general reasonableness test under Section 28-2-703 still applies.
A trade secret misappropriation claim under the Montana Uniform Trade Secrets Act generally must be brought within three years after the misappropriation is discovered, or after it reasonably should have been discovered with reasonable diligence (Montana Code Annotated Section 30-14-407). A continuing misappropriation counts as a single claim rather than restarting the clock each time. A separate breach-of-contract claim over the NDA itself follows Montana's ordinary written-contract limitations period.
Montana has no statute answering this the way California, Delaware, Illinois, Kansas, Minnesota, North Carolina, Utah, and Washington do. Without a Montana invention-assignment carve-out statute, whether an employee's own-time invention belongs to the employer depends on common-law principles, such as whether the employee was specifically hired to invent, and on the exact wording of the assignment clause in the NDA or employment agreement itself.
It depends on whether confidential information will flow in both directions or only one. A mutual NDA fits a two-way exchange, such as a merger, partnership, or joint-venture discussion where both sides disclose sensitive information. A one-way NDA fits a one-directional exchange, such as pitching a business plan to an investor who is not sharing anything confidential back. Both forms are equally enforceable in Montana; the choice is about which structure matches the actual relationship.
No. A Montana NDA is an ordinary contract, not a formal instrument like a will or power of attorney, so it does not require notarization or witnesses to be valid. It only needs the standard elements of a valid contract: an offer, acceptance, and consideration, along with signatures from the parties being bound.
The non-breaching party can seek injunctive relief to stop an ongoing or threatened disclosure, along with damages caused by the breach. If the disclosed information also qualifies as a trade secret, the Montana Uniform Trade Secrets Act provides an additional, independent basis for relief, including an injunction that lasts only as long as the trade secret advantage itself does, separate from whatever remedies the NDA itself specifies.
