The Latin legal principle “Nemo dat quod non habet” can be translated to “No one gives what they do not have” in English. This principle is often used in contract law to signify that a person cannot transfer or convey a right or property that they do not possess themselves. In simpler terms, if someone doesn’t own or have the authority to transfer a specific asset or right, they cannot legally give or sell it to another party. This concept emphasizes the importance of legal ownership and authority when making agreements or transactions.
