Fla. Stat. § 90.406 — Routine practice

Habit Evidence for Organizations: This rule is a business-focused version of an evidence concept often called "habit evidence." It allows a party to use an organization's established, consistent routine to prove that the organization likely acted in accordance with that routine on a specific occasion.

Core Principle: The rule is based on the idea that businesses and organizations rely on consistent, repeated practices to function. Evidence of such a routine is considered reliable enough to be admitted to show conformity with that practice.

Classic Example: To prove that a specific letter was mailed on a certain day, a party may not have a witness who remembers that particular letter. Instead, they can call the mailroom supervisor to testify about the company's unvarying daily routine: all letters placed in the outgoing bin by 4:00 PM are always picked up, stamped, and taken to the post office at 5:00 PM. This evidence of a routine practice is admissible to prove that the specific letter was mailed in conformity with that practice.

The statute makes it clear that this evidence is admissible on its own, even if no single person remembers the specific event and there is no other corroborating evidence.
