Intentional torts to property

The Property-and-Interference Gate: Classify Before Measuring

Property intentional-tort analysis turns first on what was invaded-land or a chattel-and then on how seriously the interference affected the claimant’s possessory right. Run the analysis in order:

1. Identify the protected property: real property or tangible personal property.
2. Identify the claimant’s possession or immediate right to possess.
3. Ask whether the defendant intentionally entered, remained, intermeddled, dispossessed, or exercised control. The required intent is intent to perform the act, not intent to violate rights, cause damage, or commit a tort.
4. Ask whether permission or another privilege defeats liability. Permission authorizes only conduct within its scope; privilege issues belong to the sibling chapter on privileges and other defences.
5. For land, stop once an unauthorized intentional entry is established. For chattels, measure the interference: actual harm supports trespass to chattels; serious interference supports conversion.

A claimant need not always prove title. Possession or an immediate right to possession generally suffices, so a lawful possessor, bailee, tenant, or other person entitled to control the property may sue against an outsider. The central near-miss is therefore not “owner versus nonowner,” but the kind and degree of interference.

The classification is a decision about the legal consequence, not merely a label for the defendant’s conduct.

Trespass to Land: The Entry Is the Injury

Trespass to land requires proof of:

1. An intentional entry onto land;
2. Possession by, or the immediate right to possess the land in, the plaintiff; and
3. Entry without permission or other privilege.

The defendant need not intend to trespass. A person who deliberately walks, drives, throws an object, or directs another object onto land has the necessary intent even if the person honestly believes the land is public, believes the boundary lies elsewhere, or thinks the entry is harmless. Mistake about ownership or boundaries is ordinarily no defence. The relevant intent is the intent to make the entry-producing movement.

The entry may be direct or indirect. Examples include walking across the parcel, driving onto it, causing a dog to enter, throwing debris onto it, or placing an object that remains there. Remaining after an authorized entry ends is also an actionable entry. Thus, a guest who was initially allowed to enter may become a trespasser by staying after permission is withdrawn or expires, subject to the scope-of-permission analysis.

Land includes the surface and the portions of the airspace and subsurface that the possessor can reasonably use and enjoy. An aircraft high above the property ordinarily does not create trespass merely because it passes over the parcel, but an intrusion into usable airspace or an excavation into protected subsurface may. The question is whether the intrusion invades the possessory use of the land, not whether the defendant crossed an abstract geometric boundary.

No physical damage, loss of market value, or other actual injury is required. A person who steps onto another’s land for one second, without authorization or privilege, can be liable even if the grass is untouched. Nominal damages are therefore available. If the entry damages a fence, crops, landscaping, or a building, the plaintiff may also seek actual damages caused by that entry.

A continuing trespass occurs when the defendant’s conduct creates an ongoing presence or condition on the land-for example, by placing debris, leaving a structure, or failing to remove an object that the defendant wrongfully put there. The initial act must still be intentional in the relevant sense. Continuing failure to remove the object can keep the invasion alive; it is not necessary to imagine a new walking entry every day.

The most important land near-misses are these:

• Boundary mistake versus accidental movement: A deliberate step across a mistaken boundary is trespass; an involuntary movement or purely accidental entry lacks the required intent for trespass to land, although another theory might apply.
• No damage versus no entry: Lack of damage does not matter once an unauthorized intentional entry occurred. Lack of any entry does.
• Permission versus physical access: An unlocked gate, visible path, or customary neighborhood route does not automatically authorize every entry or every purpose. Scope is decisive.
• Land versus an object on land: Walking onto a parcel is trespass to land; taking or damaging a bicycle sitting on it is analyzed as interference with a chattel.

Chattels by Degree: Temporary Interference or Conversion

Trespass to chattels and conversion both protect possessory control over tangible personal property. They differ mainly in the degree of interference and the remedy.

Trespass to chattels requires:

1. The plaintiff’s possession of, or immediate right to possess, a chattel;
2. An intentional act of intermeddling with or dispossessing the plaintiff; and
3. Actual harm to the possessory interest.

Intermeddling means intentionally using, touching, moving, taking, or otherwise physically interfering with the chattel. The defendant need not intend damage or know that someone else has the better right to possess it. But an accidental collision, absent an intentional act, is not trespass to chattels.

Actual harm may be shown by impairment of the chattel’s condition, quality, or value; dispossession; deprivation of use for a substantial period; or another actual injury to the protected possessory interest. A momentary, harmless contact ordinarily is not enough. Unlike trespass to land, nominal damages are not available for a purely technical chattel interference. The plaintiff must show a real loss.

For example, intentionally taking a laptop without permission and keeping it for two weeks can support trespass to chattels even if the laptop is returned undamaged, because the owner was deprived of use. Intentionally scratching the laptop can also support the claim because its condition or value was impaired. By contrast, briefly touching an undamaged chair and leaving it where it was may produce no actionable trespass to chattels.

Conversion requires:

1. The plaintiff’s ownership, possession, or immediate right to possess a chattel;
2. The defendant’s intentional exercise of dominion or control over it; and
3. Interference so serious with the plaintiff’s right to control the chattel that the defendant may justly be required to pay its full value.

Conversion can occur through taking, selling, transferring, destroying, substantially altering, withholding, or using the chattel in a manner that asserts control inconsistent with the plaintiff’s rights. The defendant need not intend to commit conversion. An honest belief of ownership or a good-faith mistake may be relevant to the seriousness analysis, but it generally does not excuse an intentional exercise of control over another’s chattel.

To decide whether interference is serious enough for conversion, consider:

• the extent and duration of the control;
• the defendant’s intent to assert a right inconsistent with the plaintiff’s right;
• the defendant’s good faith;
• the extent and duration of the resulting interference;
• the harm done to the chattel; and
• the inconvenience and expense caused to the plaintiff.

A permanent deprivation, destruction, sale, substantial alteration, or refusal to return usually points strongly toward conversion. A brief unauthorized use or minor damage ordinarily points toward trespass to chattels. The distinction is one of degree, not of the defendant’s vocabulary: calling an act “borrowing” does not prevent conversion if the conduct seriously exercised dominion.

A demand and refusal is especially important when the defendant initially obtained possession lawfully-for example, as a bailee, borrower, consignee, or repairer. If the defendant then refuses a proper demand for return, the lawful possession can become conversion. But demand and refusal is not an element in every conversion case. A wrongful taking, sale, destruction, or other serious assertion of control may constitute conversion immediately.

The remedies reinforce the distinction. Trespass to chattels ordinarily produces damages for the actual impairment, loss of use, or other proven loss. Conversion ordinarily permits recovery of the chattel’s full value at the relevant time and place, because the interference is treated as requiring the defendant to pay for the item itself. The plaintiff cannot obtain duplicative recovery by stacking full-value conversion damages on top of damages for the same interference.

A useful exam sequence is: Was there a chattel? Was the act intentional? Was there actual harm? If yes, was the interference so serious that full value is justified? If the answer to the third question is no, conversion fails even if the conduct felt unauthorized. If the answer to the fourth is yes, conversion is the stronger claim and subsumes the lesser interference for damages purposes.

Recurring errors:

• Treating a walker’s mistaken belief about a boundary as a defence when the walker deliberately crossed it.
• Requiring proof of damage for trespass to land when the unauthorized entry itself completes the claim.
• Calling every unauthorized touching of a chattel conversion instead of asking whether the interference was serious.
• Forgetting that trespass to chattels requires actual harm, such as impairment, dispossession, or substantial loss of use.
• Assuming demand and refusal is always required even when the defendant wrongfully sold or destroyed the chattel immediately.

A fenced parcel belongs to Lena, who possesses it. Mark deliberately walks across the parcel to retrieve his frisbee, although Lena gave him no permission. Mark then takes Lena’s camera from a table, sells it to a pawnshop, and keeps the proceeds. The camera is worth far more than the sale price.

Three Property Forks: Separate the Claims Under Pressure

High-Yield Points - ⚡ Biggest Takeaways

Trespass to land is complete upon an intentional unauthorized entry, even without damage. Trespass to chattels needs actual harm; conversion needs serious control warranting full-value recovery. Demand and refusal can convert lawful possession, but wrongful sale or destruction may be conversion immediately.
