DocketX / Glossary / conversion
Conversion is when someone takes or uses your personal property in a way that completely denies your right to it, as if they owned it themselves.
It is a civil wrong where the defendant seriously interferes with your possession or ownership of personal property, such as by stealing, destroying, or refusing to return it. In a case, it appears as a claim where you seek monetary compensation for the full value of the property, not its return.
It matters because, if proven, the other side may have to pay you the property’s value, even if they later try to give it back. You must show you had a right to possess the property and that the defendant acted intentionally enough to take control over it.
People often confuse conversion with ordinary theft or borrowing. Unlike theft, conversion does not require intent to steal; even an honest mistake, like keeping someone’s delivered package, can be conversion if you seriously interfere with their rights.
