Applicable law
UCC = sale of goods (all things moveable at time of identification of k)
common law = all other k
mixed k = the predominate purpose of the k determines which law governs
requirements to form valid k
mutual assent, consideration, and no defenses to formation
mutual assent
offer by one party and acceptance by another party
offer
manifestation of intent to enter into a k with definite or reasonably certain terms, communicated to an identified offeree
termination of offer
offers can be terminated before acceptance by rejection/counter offer, lapse of time, revocation, or death/incapacity
revocation of an offer
an offer may be revoked at any time before acceptance through unambiguous words or conduct indicating an unwillingness or inability to k
indirect: when offeror takes definite action inconsistent with entered into k and offeree has knowledge of that action
irrevocable offers
option k - consideration given to keep offer open for a certain period
exception: rejection of or counter offer does not constitute termination of option k or firm offer - the offeree can accept within that time as long as offeror has not detrimentally relied on the rejection
merchant firm offer - offer by merchant, in signed writing, stating offer will be held open for certain period not greater than 3 months
beginning performance on unilateral k makes the offer irrevocable – must give reasonable time to perform
acceptance
manifestation of assent to terms of the offer
performance may be adequate:
bilateral k –> start of performance manifests acceptance
unilateral k –> acceptance occurs on completion
timing of acceptance and revocation
acceptance –> offer is accepted when sent or communicated (mailbox rule: acceptance sent by mail is deemed accepted once placed in mail unless option k where acceptance must be received by date specified)
revocation –> offer is revoked when received by offeree. cannot revoke after acceptance
battle of the forms
Common law: mirror image rule - acceptance must exactly mirror the offer; any variations is a counter offer
UCC: acceptance does not have to mirror offer. additional terms are included only if:
if one party is not merchant, then additional terms are not included, and viewed as proposal to modify the k
different terms: either treated same as additional terms or knock out rule applies
knock out rule: conflicting terms in offer and acceptance are knocked out and filled by gap fillers in UCC
implied in fact contract
created by conduct if the conduct is intentional and each party knows or has reason to know the other party will interpret the conduct as an agreement
indefinite or absence of terms
if terms of an agreement are not certain, then it is not enforceable.
indefinite duration = invalid
UCC - if both parties are merchants, only essential term is quantity. if no agreement on price, reasonable price term will be supplied by UCC
consideration
bargained for exchange of any act or forbearance that benefits promisor or causes detriment to promisee
past/moral consideration –> not sufficient
merchant firm offer –> no consideration req
illusory promise –> invalid; occurs when one party has no obligation to perform (both must be bound or neither are bound)
exceptions to consideration
material benefit/unjust enrichment rule: a promise made in recognition of a benefit previously received is binding to extent necessary to prevent injustice but not applied when conferred as gift or value of promise is disproportional to benefit conferred
promissory estoppel: applies when a party reasonably and foreseeably relied to his detriment on other party promise, the promisor reasonably expected reliance, and it is necessary to avoid injustice
modification of k
pre-existing duty rule: at common law, past performance or pre-existing duty is not adequate consideration
exceptions: an addition or change in performance or fair and equitable modification due to severe unanticipated circumstances & k isnt performed by either party
UCC: no additional consideration req to modify k as long as in good faith
must be in writing is SOF or OG k states modifications have to be in writing
defenses to enforceability
SOF
k is not valid unless in writing signed by party to be charged.
writing must reasonably identify subject matter and state essential terms
applies to
• K modifications: a written k can be modified orally, but the modification must be in writing if the modification falls within the SOF
o Further, if an oral modification to an oral k puts the k into the SOF, then it must be in writing
equal dignity rule
when giving or entering an agreement authorizing someone to enter the deal on your behalf, it will fall into SOF if the underlying deal would fall into SOF
parol evidence
party cannot introduce a prior or contemporaneous agreement that contradicts a later final and exclusive written k must be (1) intended to be final expression of k and (2) fully integrated
exceptions:
1. correct clerical error
2. est defense against formation
3. interpret vague or ambiguous terms (but court will use plain meaning rule)
4. supplement partially integrated writing
5. reformation - party may seek reformation of unilateral mistake where there is misrepresentation
partially integrated writing = writing does not contain complete statement of all the terms (proof allowed if not contradicting)
fully integrated = complete and exclusive statement of terms that discharges any prior agreements
merger clause is evidence that writing is fully integrated
**does not apply to subsequent agreements
condition precedent
makes performance conditional upon completion of condition
condition is excused when the protected party fails to make good faith effort to satisfy the condition or waiver (voluntarily giving up condition), but waiver can be retracted if other party has not relied on it
obligation of good faith and fair dealing
every k contains implied obligation of good faith and fair dealing
UCC requires honesty in fact and observance of reasonable commercial standards of fair dealing
impossibility
performance is discharged when it is objectively impossible to perform b/c of death or incapacity of a person necessary to k, unanticipated destruction of subject matter, or a new, unanticipated law or regulation making performance extremely and unreasonably difficult or expensive
impracticability
performance is discharged when an event occurs after k formation that is unanticipated by both party making performance extremely and unreasonably expensive or difficult
frustration of purpose
discharges performance when the purpose of k no longer exists. occurs when a party’s principal purpose is substantially frustrated by an unforeseeable superseding event outside their control and both parties knew of the purpose at the time of formation
