What It Means to Know Something Under the Trust Code

Deadlines in this chapter run from knowledge. This section decides when you had it.

Section 736.0104 defines knowledge three ways, including what a person had reason to know, and gives corporate trustees a rule of their own.

Quick Overview

What counts as knowledge

Topics to Know HideShow

Below, we walk through the 4 issues that decide whether this is the right move for you. Jump to any one.

  1. Three routes to knowledge Actual, notified, or reason to know.
  2. Why it matters Limitations periods in this chapter run from knowledge.
  3. A rule for organizations A corporate trustee knows only through the right employee.
  4. One judicial limit Knowing is not the same as an act the trust requires.

That’s the quick version. The details below are what decide your situation, and where the costly mistakes hide.

Three ways to know a thing

This is a short section that does a lot of work, because deadlines in the Florida Trust Code run from knowledge rather than from events. The clock in section 736.1008 is the obvious example.

Subject to subsection (2), a person has knowledge of a fact if the person:

(a) Has actual knowledge of the fact;

(b) Has received a notice or notification of the fact; or

(c) Has reason to know the fact from all the other facts and circumstances known to the person at the time in question.

Section 736.0104(1), Florida Statutes.

Paragraph (a) is what people mean by knowing. Paragraph (b) is administrative. A notice was sent and received, whether or not it was read. Paragraph (c) is the dangerous one. It attributes knowledge you did not have, on the basis of what you did have, and it is how a beneficiary who never received an accounting can still find a limitations period running.

Note the words at the time in question. Reason to know is assessed on what the person knew then, not on what became obvious later.

Organizations know differently

Subsection (2) exists because a bank is not a person and cannot know anything. It provides that an organization has notice or knowledge of a fact involving a trust only from the time the information reached an employee with responsibility to act on matters involving that trust, or would have reached that employee had the organization exercised reasonable diligence.

It then defines reasonable diligence as maintaining reasonable routines for communicating significant information to the responsible employee, and reasonably complying with those routines. And it adds a limit. Reasonable diligence does not require an employee to pass on information unless doing so is part of their regular duties, or they know a trust matter would be materially affected.

Read from a beneficiary’s side, this is a shield. Telling a branch teller is not telling the trustee. Read from the corporate trustee’s side it is a standard, because an institution with no routines at all cannot claim the protection.

The only Florida decision on this section

A search for this section number returns exactly one document in the whole of Florida, and it is a 2023 Second District appeal about whether a settlor validly amended his trust. His method required delivery of the amendment to the trustees, and one trustee never got it. The proponent argued he knew anyway.

Violetta argues that despite the lack of delivery, Paul still had constructive knowledge of these events under section 736.0104(1)(c)’s definition of knowledge.

Grassfield v. Grassfield (Fla. 2d DCA Dec. 13, 2023), footnote 4.

The court rejected it. Its reasoning was that the argument ignored the plain language of the trust, which required delivery to a trustee rather than merely knowledge by one. It then added a second, independent ground.

And even if a trustee’s knowledge was sufficient, Violetta did not satisfy her burden on summary judgment to prove Paul’s knowledge.

Grassfield v. Grassfield, same footnote.

Two points come out of that, and both are useful.

First, this section defines knowledge; it does not convert knowledge into performance. Where the trust instrument, or the Code, requires an act, showing that someone knew about the act is not the same as doing it.

Second, knowledge is a fact to be proved. The party asserting it carries the burden, and on summary judgment that is a real obstacle. The evidence in that case was unusually specific. The trustee still had access to the online account, looked at the portfolio every few months, and said he usually would not look at the statements. It was not enough.

Where this section actually bites

Nobody litigates section 736.0104 on its own. It arrives inside another argument, almost always about time. When a trustee says a claim is too late, the question underneath is when the beneficiary knew, and that is answered here.

It is worth reading together with section 736.0109, which governs how notice may be given, including by posting to a website. The two interlock. One decides what counts as being told, and the other decides what counts as knowing.

A trustee says you knew

Constructive knowledge is real, but a court has held it does not substitute for an act the trust document requires.

Frequently Asked Questions

How does Florida law define knowledge for trust purposes?

A person has knowledge of a fact if they have actual knowledge of it, have received a notice or notification of it, or have reason to know it from all the other facts and circumstances known to them at the time.

What is reason to know?

It is constructive knowledge. You are treated as knowing something you did not actually know, because the other things you did know made it apparent. It is the widest of the three routes and the one that causes the most difficulty.

When does a corporate trustee know something?

Only from the time the information reached an employee with responsibility to act on matters involving the trust, or would have reached that employee had the organization exercised reasonable diligence. Reasonable diligence means maintaining reasonable routines for passing on significant information and actually complying with them.

Can a trustee rely on my constructive knowledge instead of doing what the trust says?

Not according to the one Florida decision to address it. In 2023 the Second District rejected an argument that constructive knowledge under this section could stand in for delivery of documents to a trustee, where the trust itself required delivery.

Has this section been amended?

No. It has stood unchanged since the Trust Code was enacted in 2006.

Common Situations

A trustee argues you knew years ago. Reason to know is judged on what you knew at the time, and must be proved.

You told someone at the bank. An organization knows through the employee responsible for the trust.

The trust required a document be delivered. Knowledge of the document is not delivery of it.

A limitations argument has appeared. This section is usually where it is actually decided.
