Trust law in the United States is largely governed at the state level, which means the way trusts are created, managed, and interpreted can vary from one state to another. To make trust laws more consistent, many states have adopted some version of the Uniform Trust Code (UTC).
Oklahoma has officially joined them with the Oklahoma Uniform Trust Code — a new law that went into effect November 1, 2025. It is important to note, however, that Oklahoma did not adopt the entirety of the Uniform Trust Code, but rather a majority of its provisions.
What Is the Uniform Trust Code?
The Uniform Trust Code was first drafted in 2000 by the National Conference of Commissioners on Uniform State Laws with the goal of bringing basic principles of trust law into one clear, consistent framework.
Before the UTC, each state had its own patchwork of trust statutes, making it difficult for trustees and beneficiaries to know exactly what rules applied. The UTC provided a model law that states could adopt and adapt to their needs.
At the start of 2025, 36 states had adopted some version of the UTC. Oklahoma became the 37th when House Bill 1850 was signed into law in May of 2025.
Key changes under the Oklahoma Uniform Trust Code
For both trustees and beneficiaries, the new law provides clearer guidance and greater accountability in several key areas:
Defines trustee duties. Trustees are required to act prudently, in good faith, and in the best interests of the beneficiaries.
Increases transparency. Trustees must provide certain information to beneficiaries, including periodic accountings and updates related to the administration of the trust.
Clarifies modification and termination. The law provides clearer guidance on when and how a trust can be modified, terminated, or severed.
Sets remedies for breach of trust. Beneficiaries now have more clearly defined options for remedies if a trustee fails to meet their obligations or breaches any of their fiduciary duties.
While the new state law applies to all trusts, the most significant impact will likely be on irrevocable trusts, where trustees and beneficiaries rely more heavily on statutory direction.
What trustees and beneficiaries should know
The new law reinforces the importance of documentation and communication. One major change for irrevocable trusts is the new accounting requirements for trustees. Trustees should review their accounting and reporting practices to ensure they comply with the new law’s standards. It also clarifies when trustees can delegate responsibilities and when court approval is required for certain actions. The new law even allows the court to question a trustee’s discretionary actions under a trust, which is a change from existing trust law in Oklahoma.
For beneficiaries, the new law provides greater access to information. In the past, disclosure rules were less specific about what information beneficiaries could request. The Oklahoma Uniform Trust Code gives beneficiaries a stronger right to receive updates, financial summaries, and key trust documents, which helps ensure that everyone involved understands how the trust is being managed.
Overlap with prior Oklahoma trust laws
When the Oklahoma legislature passed the Oklahoma Uniform Trust Code, it did not repeal the state’s existing trust statutes. Instead, the new law became an additional layer to the existing Oklahoma Trust Act. Existing case law will also still be relevant in interpreting statutes.
This means that in some cases, there may be overlap or even conflict between old and new rules. When that happens, courts and attorneys will need to interpret which statute applies. For trustees and beneficiaries, that makes professional legal guidance especially important during this transition period.
A step toward clarity and consistency
The Oklahoma Uniform Trust Code codifies important aspects of trust law and strengthens protections for both trustees and beneficiaries. It promotes transparency and accountability, and provides clearer guidance for managing trusts in the years ahead.
Good news for our clients
The good news for the majority of our clients is that the Oklahoma Uniform Trust Code does not affect the validity of any existing estate planning documents. The new law largely affects the administration of irrevocable trusts and requires trustees of those types of trusts to do their due diligence in ensuring they are complying with the new requirements for accountings.
