A more thorough explanation:

Definition: De fide instrumentorum is a Latin term used in Roman and Scots law to refer to the reliance that can be placed on written documents. It is often used in cases of rescission based on forgery.

Example: If someone forges a signature on a contract, the other party may be able to rescind the contract based on the principle of de fide instrumentorum. This means that the forged document cannot be relied upon as a valid agreement.

Explanation: The example illustrates how de fide instrumentorum is used in cases of forgery. It highlights the importance of written documents in legal proceedings and the need for them to be authentic and trustworthy. If a document is found to be forged, it cannot be relied upon as evidence or proof of an agreement.
