Fiction of Law: What It Is and Why It Matters

In this episode, I unpack the concept of “fiction of law” as defined in Black’s Law Dictionary (6th ed.) and explore how legal fictions differ from estoppel and presumptions. I break down how a fiction of law accepts what is known to be false as true for procedural ends, while presumptions are inferences the law won’t allow to be controverted—even if you might be right. We discuss how procedure extends rules beyond their proper scope, why this can feel arbitrary, and how these doctrines can shape courtroom outcomes. I also examine the idea of “fictitious” and “fictitious names,” tracing meanings of Christian name and patronymic, and how naming conventions appear across documents like passports, driver’s licenses, and financial instruments. Along the way, I highlight how legal labels and procedural shortcuts can maintain the status quo and why understanding these distinctions—fiction, estoppel, presumption, and naming—matters for anyone navigating the legal system.
