Volenti non fit injuria.

Volenti non fit injuria (Latin words) means, "To a willing person, injury isn't done". This is a common law doctrine which stipulates that, an individual who pose himself at a position where he may get harm, he is not entitled to a right to claim damages when happens he get harm.

Volenti applies only to the risk which a reasonable person would consider them as having assumed by their actions; thus a wrestler consents to being hit, and to the injuries that might be expected from being hit, but does not consent to (for example) his opponent striking him with any other object which is prohibited by rules of wrestling. Volenti is also known as a "voluntary assumption of risk".

Volenti is sometimes described as the plaintiff "consenting to run a risk". In this context, volenti can be distinguished from legal consent in that the latter can prevent some torts arising in the first place. For example, consent to a medical procedure prevents the procedure from being a trespass to the person, or consenting to a person visiting one's land prevents them from being a trespasser.
