Definition: Oyer, demand of is a legal term that refers to a party's right to request to hear, read, or inspect a deed that has been mentioned in a pleading by the opposing party. This is also known as demand of oyer.

Example: If a plaintiff files a lawsuit claiming that the defendant owes them money based on a written contract, the defendant may make a demand of oyer to see the contract in question. This allows the defendant to verify the terms of the contract and determine if they are indeed obligated to pay the plaintiff.
