A Question Many Families Never Think to Ask
Families building a trust to genuinely benefit multiple generations often assume the trust can simply continue indefinitely, without realizing Montana law actually places a specific limit on how long a trust structure can genuinely last. Understanding this framework matters considerably for anyone in Bozeman planning for grandchildren or even great-grandchildren.
This assumption often only surfaces once a family starts researching trust duration specifically, at which point discovering Montana’s actual limit can meaningfully change how the entire plan actually gets structured.
What Montana’s Rule Against Perpetuities Actually Requires
Under Montana’s Uniform Statutory Rule Against Perpetuities, codified at Montana Code § 72-2-1002, a trust interest must vest within either lives in being at the trust’s creation plus twenty-one years, or ninety years from the trust’s creation, whichever period a court applies. A Bozeman estate planning attorney explains Montana has not abolished this rule, meaning a truly perpetual trust structure is not actually available under current Montana law.
- Montana follows USRAP, capping trust duration at 90 years or lives plus 21
- Montana has not abolished the traditional rule against perpetuities
- Montana adopted the Uniform Trust Code under Title 72, Chapter 38
- The framework still allows trusts to span multiple full generations
Why This Distinguishes Montana From Certain Other States
A handful of states have abolished their rule against perpetuities entirely, allowing trusts established there to theoretically last indefinitely across countless future generations. Montana has not taken this approach, meaning families specifically seeking a truly perpetual trust structure sometimes look to establish that particular trust under a different state’s law instead.
Why the Ninety-Year Window Still Offers Real Flexibility
Even though Montana trusts cannot last forever, a ninety-year duration still comfortably spans three or four generations for most families, offering substantial multi-generational planning benefits without requiring an out-of-state trust structure. A Bozeman estate planning attorney building a long-term trust works within this genuine timeframe to accomplish most families’ actual generational planning goals.
Does the Ninety-Year Rule Apply to Every Kind of Trust
Generally, yes, for most trusts subject to Montana’s rule against perpetuities analysis. Certain specific trust types, such as charitable trusts and some retirement plan trusts, can qualify for exceptions under the broader statutory framework, though these exceptions apply narrowly rather than broadly across ordinary estate planning trusts.
What the Uniform Trust Code Actually Governs
Montana adopted the Uniform Trust Code under Title 72, Chapter 38 of the Montana Code Annotated, providing a comprehensive framework governing trust creation, modification, termination, and trustee duties throughout the entire life of a trust. This framework gives both settlors and trustees clear, predictable rules to follow rather than relying solely on scattered common law principles.
Whether an Irrevocable Trust Can Actually Be Modified Later
Yes, under specific circumstances. Montana law allows an irrevocable trust to be modified or terminated with the consent of the settlor and all beneficiaries, even when that change would otherwise conflict with a stated purpose of the trust. Separately, a trust can also be modified through decanting or by court order when circumstances have genuinely changed since the trust was originally created.
Why Trustee Selection Matters for a Long-Term Trust
A trust designed to genuinely last multiple decades needs a trustee, whether an individual or an institution, capable of administering the trust responsibly for the entire duration involved. Montana’s Uniform Trust Code imposes specific duties on trustees, including prudent investment standards and a duty to keep beneficiaries reasonably informed throughout the trust’s administration.
Why Reviewing Your Trust’s Duration Genuinely Matters
Understanding exactly how long your specific trust structure can actually last, and what happens as that timeline approaches its end, helps confirm your multi-generational planning goals genuinely get accomplished as originally intended. A trust reaching its statutory limit without a clear distribution plan can create confusion for the generation ultimately receiving the remaining assets.
