Common questions
Frequently Asked
3
What conduct satisfies the serious interference element of conversion?+
Intentional destruction or material alteration of a chattel changes its identity and supports liability. Serious unauthorized use that violates the owner's right to control the chattel also qualifies.
Does conversion require the defendant to obtain personal benefit?+
No. The tort focuses on the interference with the plaintiff's right to control the chattel. The defendant need not gain personally from the act.

Conversion requires serious interference that justifies forcing a sale of the chattel to the defendant at full value. Trespass to chattels addresses lesser interferences remedied by damages for harm or loss of use.
