Prenuptial Agreement in
Montana

Montana adopted the Uniform Premarital and Marital Agreements Act (MCA § 40-2-601 et seq.), which requires prenups to be in writing, signed voluntarily by both parties, and supported by fair and reasonable financial disclosure.

Yes. A prenup can designate ranch property and appurtenant water rights as the separate property of one spouse, preventing them from being subject to equitable division in a divorce. This is especially important for multi-generational ranching operations.

Mineral rights and royalty income can be explicitly addressed in a Montana prenup. If you own mineral interests before marriage, the prenup can designate both the underlying rights and any income they produce as your separate property.

Montana does not mandate independent counsel by statute, but courts weigh voluntariness carefully under the UPMAA. Both spouses having their own attorneys is the clearest evidence that the agreement was entered into freely and with full understanding.

Yes. Montana law permits prenuptial provisions that modify or waive spousal support. Courts will scrutinize such provisions for unconscionability and may decline to enforce them if circumstances changed dramatically and enforcement would be manifestly unjust.

No. Montana's Uniform Premarital Agreement Act (Mont. Code Ann. § 40-2-604) requires only a written agreement signed by both parties — no notary, no witnesses, and no consideration beyond the marriage itself. Notarizing is still worth the small effort because it documents the signing date and identities, which helps if voluntariness is ever disputed. Couples can prepare the agreement themselves and sign it before a notary in a single short visit.

Yes. Nothing in Montana law requires a lawyer to draft a premarital agreement — the UPAA asks for a written contract, signed voluntarily by both parties, ideally with fair disclosure of each person's property and debts attached. A well-built template or online service that covers property division, debts, appreciation, and support, with state-specific terms, satisfies those requirements. Sign well before the wedding, and consider an optional attorney review if your assets include a ranch, business, or inheritance.

In Montana, attorney-drafted prenups generally cost $1,000 to $3,000, though Bozeman and Missoula rates have climbed with the state's wealth influx, and agreements covering ranches, water rights, or family businesses can run well past $4,000. The UPAA's requirements — a written, signed, voluntary agreement with fair financial disclosure — can be met just as well by creating the document online for a flat $349, with an optional one-time review by a Montana attorney for extra peace of mind.

With prenups.ai, you can have a draft prenuptial agreement in under 20 minutes. Traditional attorney routes in Montana typically take 2–6 weeks due to scheduling, drafting, negotiation, and review. No specific statutory timing requirement under the UPMAA. Adequate review time is expected. We recommend starting the process at least 2–3 months before your wedding to allow time for review and any revisions.

Yes. Montana does not require you to have an attorney to create a valid prenuptial agreement. However, having each party consult with independent legal counsel significantly strengthens enforceability. Many couples use prenups.ai to create the initial draft and then have it reviewed by attorneys, which is much more affordable than starting from scratch.

Without a prenup, Montana's default equitable distribution rules apply. Montana follows equitable distribution. Marital property is divided fairly by the court. A prenup lets you define your own terms instead of leaving these decisions to state law or a judge's discretion.
