Tort LawLegal glossary term
Quick answer
Conversion usually means the unauthorized taking or control of another’s personal property. In contracts, it matters because the wrongdoer can be sued for the item’s full value. Before signing, check who holds title and what rights you have if the other side seizes the property.
Definitions
What is conversion?
Legal Definition
When a party wrongfully takes another's personal property, the law calls that conversion. The owner may sue for the property's full value plus damages under tort law. A key distinction is that conversion requires intent to exercise control, not merely negligence.
Plain-English Translation
If a kid grabs a classmate’s lunchbox and refuses to give it back, the school treats it like conversion.

Missing or vague
If conversion is missing or vague
If the contract does not define conversion, parties may disagree on what actions count as wrongful control. One side might argue that routine maintenance qualifies, while the other sees it as conversion. This ambiguity can lead to costly litigation over damages and ownership rights.
Without a clear definition, the risk of unexpected liability increases, especially for lenders and landlords who might inadvertently seize property. Courts will interpret vague clauses against the drafter, potentially awarding full market value even for minor infractions.
