Revoked Consent to Enter Land
Keisha Kincaid owns a parcel and initially consents to entry by Karina Kovacs for a survey. Keisha later sends written revocation of consent. Karina continues onto the land after receiving the letter but claims she never read it. The letter's delivery supplies the required knowledge that consent has ended.
Merchant Receives Contract Confirmation
Kurtis Kaiser, a retail merchant, receives a signed order confirmation from Knowledge Partners listing styles and quantities of goods priced above five hundred dollars. The confirmation arrives at his business address. Kurtis does not open the envelope and raises no objection within ten days. The receipt of the record satisfies the statute of frauds against him.
Divergent Meanings Attached to Term
Krypton Industries and Kelvin Kimura execute a services contract using the word intensive without defining it. Internal messages show each attached a different meaning to the term yet neither inquired further. Performance later becomes impossible under one interpretation. The absence of knowledge about the other's meaning prevents mutual assent on that term.
Landlord Knows of Risky Tenant Activity
Kite Finance leases a warehouse to a tenant that will operate a public gaming arcade. Before the lease the landlord observes corroded railings on a mezzanine that fail current codes. The landlord does nothing to repair or barricade the area. A customer falls during an event and is injured. The landlord's pre-lease observations establish the required knowledge of the unreasonable risk.
Common questions
Frequently Asked
4
How does reason to know differ from actual knowledge under the Restatements?+
Reason to know exists when a party has information that would lead a reasonable person to infer the fact or to act on the assumption that the fact exists. Actual knowledge requires subjective awareness. The distinction matters in incapacity and nondisclosure cases because constructive knowledge can trigger liability even without subjective awareness.
When does a landlord have reason to know of a dangerous condition under landlord-tenant rules?+
A landlord has reason to know when an inspection report or other information describes a concealed hazard that existed at the time of leasing. The landlord must also realize the risk and expect the tenant will not discover it. Failure to disclose then creates liability to the tenant and permitted entrants.
Does receipt of a confirmation create reason to know its contents under the UCC statute of frauds?+
Receipt of a signed confirmation sent between merchants satisfies the statute against the recipient if the recipient has reason to know its contents. The recipient must object within ten days or the confirmation binds the recipient even without a signature. Failure to open the document does not negate reason to know.
What knowledge standard applies when parties attach different meanings to a contract term?+
No contract forms on the term if neither party knows or has reason to know the meaning attached by the other. Each party must lack information that would alert a reasonable person to the other's divergent understanding. Conscious execution despite known ambiguity prevents mutual assent.
