An intentional assertion of authority over a chattel that substantially deprives its owner of the ability to direct its use or disposition. The interference must be serious enough that the law treats the conduct as a forced sale requiring payment of the chattel's full value. Duration, inconsistency with the owner's rights, and alteration of the property are relevant to measuring seriousness.

Rancher Cole lent his breeding bull to farmer Miller for one season. Miller branded the bull with his own mark, listed it in his sale catalog, and sold it at auction. Cole sued Miller. The branding and sale constituted an exercise of dominion or control that permanently excluded Cole from possession, supporting conversion liability.
Investor Evan stored gold coins with Apex Investments. Portfolio manager Lara removed the coins, took them home, and pledged them as security for her personal bank loan for four weeks before redeeming and returning them. Evan sued Lara. The multi-week pledge asserted dominion inconsistent with Evan's rights and supported conversion even though the coins were returned intact.
A shipping clerk negligently delivered a customer's specialized machinery to the wrong warehouse. The recipient stored the equipment without using it and returned it upon discovery of the error. The customer sued the shipper. Because the clerk did not intentionally exercise dominion or control, no conversion occurred despite the misdelivery.
A bailee stored specialized farm equipment belonging to a chicken producer. The bailee repeatedly used the equipment for its own commercial operations over several months, rendering it unavailable to the owner. The owner sued the bailee. The sustained assertion of control over the chattel effected conversion by depriving the owner of meaningful dominion.
Trespass to chattels addresses lesser interferences that cause only minor damage or temporary loss of use. An exercise of dominion or control rises to conversion when the interference is serious enough to justify requiring the actor to pay the chattel's full value rather than merely compensating for actual harm.

Brief or minor handling usually supports only trespass to chattels. Duration and the extent of inconsistency with the owner's rights determine whether the conduct crosses into conversion. Pledging property as collateral for several weeks or reconfiguring it for long-term institutional use has been treated as serious enough.
…and not merely temporary, normally would be the equivalent of a fee interest. It would be a definite exercise of complete dominion and control over the surface of the land. The fact that the planes never touched the surface would be as irrelevant as the absence in this day of the feudal livery of seisin on the transfer of real…

No. The actor must intend the act that asserts control, but need not intend legal harm or even know the property belongs to another. Branding and selling a borrowed animal or wiping and reassigning a lent laptop satisfy the intent element even if the actor claims good faith.

No. The Restatement expressly provides that one who does not intentionally exercise dominion or control is not liable for conversion even if the act or omission is negligent. Misdelivery without intent therefore supports at most a negligence claim.
