A more thorough explanation:

Definition: False demonstration, also known as falsa demonstratio, refers to an incorrect or misleading description of a person or thing in a legal document.

For example, if a will mistakenly identifies a beneficiary by the wrong name, this would be considered a false demonstration. However, minor errors such as spelling mistakes or grammatical errors would not necessarily invalidate the entire document.

Another example of false demonstration could be if a contract describes a property as having a certain number of acres, when in reality it has a different amount. This could lead to legal disputes if the incorrect information was relied upon by one of the parties involved.

Overall, false demonstration refers to any inaccurate or misleading information in a legal document that could potentially cause confusion or disputes.
