The legal power of a third party to grant valid consent to an interference with another's property or privacy rights. This power exists when the third party shares common authority over the premises or chattel or otherwise holds the ability to permit the interference. Consent from such a person binds the owner or occupant even if the owner later objects.

Meter Reader Enters Backyard
Kirk, a utility technician, entered Dominic's fenced backyard after Regina, the next-door neighbor, assured him that Dominic was away and entry was fine. Regina had no access rights or control over Dominic's property. Dominic later sued Kirk for trespass. The court held Kirk liable because Regina lacked authority to consent on Dominic's behalf.
Roommate Consents to Apartment Search
Detectives investigating fraud arrived at an apartment shared by Vernon and Queen. Queen, who paid half the rent and held a key, invited the officers inside and unlocked a home office door using a spare key from a common drawer. Vernon later moved to suppress evidence seized from the office. The court ruled Queen's common authority over the premises made her consent effective against Vernon.

Storage Manager Allows Beeper Tracking

Spouse Refuses Search Despite Other Consent
Police sought to search a home for drug evidence. Janet Randolph consented, but her husband Scott Randolph, who was present, expressly refused. Officers searched anyway based on Janet's consent and found incriminating items. The court suppressed the evidence because one occupant's refusal overrides the other's consent when both are present.

Common questions
Frequently Asked
4
When does a co-occupant have authority to consent to a search of shared premises?+
A co-occupant has authority when the person has common authority over the premises through mutual use or joint access and control. Courts assess whether the consenting party could permit the search in their own right. Apparent authority also suffices if officers reasonably believe the person has such power.
Supporting sources
Does one occupant's refusal override another's consent to a search?+
Yes. When a physically present co-occupant expressly refuses consent, that refusal controls and invalidates the search even if another occupant consents. The refusal demonstrates that the search is not based on mutual agreement among those with authority.
Supporting sources
Can a third party consent to entry onto land they do not control?+
No. Only the possessor or someone with actual or apparent authority to consent on the possessor's behalf may grant effective consent. A neighbor or other unrelated person lacks this power, so their consent does not protect an entrant from trespass liability.
Supporting sources
Does a parent always have authority to consent to a search of an adult child's locked containers?+
No. A parent with access to a room may consent to a search of the room itself but lacks authority over locked containers under the child's exclusive control. The container's separate privacy interest prevents the parent's consent from extending to it.
