A legal presumption is a rule that lets or requires a court to treat a fact as true unless it is rebutted or the rule provides otherwise.
Presumptions help legal systems allocate proof and manage common factual assumptions.
Why a legal presumption matters
Presumptions can affect who must produce evidence and what happens if no contrary evidence appears.
They can be decisive when the available proof is thin, when a statute creates a starting assumption, or when a party must overcome a default rule.
Where a legal presumption appears
Legal presumptions appear in evidence law, family law, probate, criminal procedure, administrative law, property records, and statutory interpretation.
Some presumptions are rebuttable. Others may be conclusive in specific settings.
How it differs from nearby terms
A legal presumption is a starting rule about how a fact is treated. Admissible evidence is information the court may consider.
A prima facie case is an initial showing on required elements, while a presumption may help establish or shift the treatment of a particular fact.
Practical example
A statute may presume that a mailed notice was received after a set number of days. The other party may be allowed to present evidence that the notice was not actually received.

Question: Is every legal presumption impossible to challenge?
Answer: No. Many presumptions are rebuttable, but the exact effect depends on the rule.
