In August 2025, Minnesota made a major change to its trust laws that will reshape estate planning for decades to come. The state extended the Rule Against Perpetuities for trusts from 90 years to 500 years. This means families can now create what are called dynasty trusts—trusts designed to last for centuries.
This change is more than just a technical tweak. It opens the door for Minnesotans to preserve wealth, farmland, and family businesses for multiple generations without being forced to break up assets or go through repeated probate processes. In this article, we’ll explain what the Rule Against Perpetuities is, why the law changed, and how farming families and others can take advantage of this new opportunity.
What Is the Rule Against Perpetuities?
The Rule Against Perpetuities is a legal concept that limits how long property can remain in a trust before ownership must become certain. In simple terms, vesting means someone has a guaranteed right to the property. Under the old Minnesota law, trusts had to vest within 90 years. That meant even if you wanted your trust to last longer, the law eventually forced it to end.
Now, thanks to the 2025 update, trusts can last up to 500 years from the death of the grantor. This is a dramatic shift. Instead of planning for just your children and grandchildren, you can create a trust that benefits your family for 10, 15, or even more generations.
Why Did Minnesota Make This Change?
Minnesota’s legislature recognized that modern families need more flexibility in planning for the future. Other states—like South Dakota, Delaware, and Nevada—already allow very long-lasting trusts, and Minnesota wanted to remain competitive. By extending the perpetuities period to 500 years, Minnesota gives residents the ability to keep wealth and property in the family for centuries.
This change was part of a broader update to the Minnesota Trust Code and Probate Code. The 2025 legislation also clarified rules for directed trusts, raised thresholds for terminating small trusts, and addressed powers of attorney and trust modifications.
What Does This Mean for You?
The ability to create a trust that lasts for five centuries opens new doors for multigenerational wealth planning. Here’s what that looks like in practice:
First, it means you can keep assets—whether it’s farmland, a family business, or an investment portfolio—under one umbrella for generations. Instead of passing property outright to heirs (which often leads to fragmentation and disputes), you can maintain control through a trustee and clear governance rules.
Second, dynasty trusts can help reduce exposure to federal estate and generation-skipping transfer taxes. While tax laws may change over time, a properly structured trust can lock in advantages and minimize future tax burdens.
Finally, these trusts offer strong asset protection. Property held in trust is generally shielded from creditors, lawsuits, and divorces. That means your family’s wealth is less vulnerable to unexpected events.
Why Should Farming Families Care?
For Minnesota’s farming families, this change is especially important. Agricultural land isn’t just an asset—it’s a way of life and a source of income. Under the old 90-year rule, trusts eventually had to end, which often led to:
- Partition Sales: When heirs couldn’t agree, land was sold to divide ownership.
- Loss of Operational Control: Farms broken up among multiple owners, making management difficult.
- Tax Burdens: Estate taxes triggered by transfers, forcing families to sell land to pay the bill.
With a 500-year trust, you can avoid these problems. Imagine creating a trust that holds your family farm for centuries. The trust could appoint a farm manager or trustee to oversee operations, distribute income to family members, and ensure the land stays intact. This approach preserves both the economic value and the heritage of the farm.
For example, a dynasty trust could hold 1,000 acres of farmland, appoint a trustee with agricultural expertise, and set rules for reinvesting profits into equipment or land improvements. Beneficiaries would receive income without having to sell the property. This structure avoids the “heirs’ lottery” and maintains operational continuity.
Other Key Updates in 2025
The new law didn’t just extend the perpetuities period. It also made other important changes:
- Directed Trusts: Minnesota clarified the roles of investment advisors, distribution advisors, and trust protectors. These individuals can guide trustees on specific decisions, adding flexibility to trust management.
- Uneconomic Trust Termination: The threshold for ending small trusts without court approval increased from $50,000 to $150,000.
- Modification Rules: Powers of attorney can now modify certain trust terms under Minn. Stat. §§ 501C.0411 and 501C.0602, making it easier to adapt trusts when circumstances change.
Plain Language Summary
- Old Rule: Trusts had to end within 90 years.
- New Rule: Trusts can last 500 years.
- Why It Matters: You can keep property—like farmland—in the family for centuries.
- Who Benefits: Families with significant assets, especially farms and businesses.
