Requirements one by one
Missouri uses two 120-day clocks
RSMo § 456.8-813.2(2) begins when the trustee accepts the trusteeship. Within 120 days, the trustee notifies qualified beneficiaries of the acceptance and gives the trustee's name, address, and telephone number.
Subdivision 2(3) begins a separate 120 days when the trustee acquires knowledge that an irrevocable trust was created or that a formerly revocable trust became irrevocable, whether by the settlor's death or otherwise. That notice states the trust's existence, identifies the settlor or settlors, and states rights to request the trust instrument and a trustee's report.
The trust can vary the duty only above a mandatory floor
Missouri generally lets the trust terms prevail. Section 456.1-105.2(8), however, protects a narrower core: a trustee of an irrevocable trust must notify each permissible distributee age 21 or older of the trust's existence and rights to request reports and other reasonably related administration information.
The settlor may designate one or more permissible distributees in the trust to receive that notice, information, or reports instead of another permissible distributee who is an ancestor or lineal descendant of the designee. Trust terms may vary the broader qualified-beneficiary notices to the extent they do not erase this mandatory floor.
Delivery and waiver are functional
Section 456.1-109 requires a method reasonably suitable under the circumstances and likely to result in receipt. Examples include first-class mail, personal delivery, delivery to the last known residence or business, and a properly directed electronic message. A person whose identity or location is unknown and not reasonably ascertainable need not receive notice, and the statute requires no publication fallback.
The person entitled to notice may waive it. Section 456.8-813.4 also permits waiver of reports or other information and prospective withdrawal. Neither provision requires a signed writing.
Information requests can carry a fee and confidentiality condition
A beneficiary's information request must concern one sufficiently identified trust so the trustee can locate its records. The trustee may charge a reasonable fee for providing information.
If the trustee is bound by confidentiality restrictions for a trust asset, a beneficiary eligible for information about the asset must agree to those same restrictions before receiving the information.
What trips people up
- The deadline is 120 days, not 60. Both clocks use the same longer period.
- The notices have different contents. Acceptance/contact information belongs to the first; trust existence, settlor identity, and request rights belong to the second.
- Age 21 applies to the mandatory floor. It is not age 25, and it does not replace the broader default qualified-beneficiary class.
- Annual-report recipients are narrower. Permissible distributees receive reports automatically; other beneficiaries receive them when requested.
- No sworn service package is required. The statutes impose no trustee oath, signature, notarization, certified mail, return receipt, acknowledgment, or proof-of- service certificate.
Common questions
Who counts as a qualified beneficiary?
Section 456.1-103(21) uses three horizons: a current permissible distributee, a person who would become one if the current interests ended, and a person who would become one if the trust terminated on the determination date.
How does a trustee accept?
Section 456.7-701 follows the method in the trust. If none is stated or it is not exclusive, delivery of trust property, exercising trustee powers or duties, or another indication can establish acceptance.
Who receives duties while the trust remains revocable?
Under § 456.6-603, beneficiary rights remain subject to the settlor's control and trustee duties are owed exclusively to a settlor who has capacity to revoke. Capacity is presumed until adjudication or the trustee receives an affidavit of incapacity.
Which older trusts are outside the current section?
Section 456.8-813 does not apply to a trust created under an instrument that became irrevocable before January 1, 2005. The statute continues the prior law for those trusts.
