Offer, Acceptance and Agreement

Agreement analysis asks whether outward words and conduct show a final willingness to contract. An offer is sufficiently definite and indicates that acceptance will conclude the bargain. An invitation to treat seeks offers or further negotiation. Displays, advertisements, tenders and auctions often follow characteristic patterns, but wording and context can reverse the default.

An offer must remain open when acceptance becomes effective. Rejection, counter-offer, lapse, failure of condition and effective revocation can terminate it. Acceptance must correspond with the offer and comply with any mandatory method. Postal and instantaneous communications may use different timing rules, while electronic dealings require attention to dispatch, receipt and the agreed system.

Certainty and completeness are not afterthoughts: assent to an arrangement with unresolved essential terms may not create an enforceable contract. A strong answer constructs a timeline, gives each event a legal character and argues both sides where communication or commitment is ambiguous.

Distinguish an inquiry from a counter-offer

Q [4 marks]. A buyer asks whether a seller would accept delivery one week later, then sends an unqualified acceptance before receiving a reply. Explain four issues. The mark allocation is an editorial study aid, not an official university assessment scheme.
  • 1Classify the original communication and identify its open terms.
  • 1Read the buyer's question objectively as an inquiry or a rejection with substituted terms.
  • 1Determine whether the offer remained capable of acceptance when the later message was sent.
  • 1Test the later message for unqualified correspondence with the original offer and conclude conditionally.
A request for information can leave the offer alive, while a counter-offer rejects and replaces it. Wording and context control. If the first message merely asks about possible delivery and the later message accepts the original terms, agreement may form, subject to communication rules.
Sia tip — Quote the operative words and describe what they would communicate to a reasonable recipient.
Glossary

FAQ

Offer, Acceptance and Agreement FAQ

What distinguishes an offer from negotiation?

An offer communicates final commitment on stated terms if accepted. Negotiation leaves approval, price, quantity or another essential step open. Analyse language and commercial setting together.

Does a price quotation create an offer?

Not necessarily. A quotation can supply information without promising to sell. Quantity, availability, wording and the requested response determine whether final commitment is present. Examine whether any final approval remains with the speaker.

When does a counter-offer matter?

It ordinarily rejects the original offer, so later acceptance of the old terms may be ineffective unless the offer is renewed. A mere inquiry can leave the original offer open.

Can revocation be effective without direct words from the offeror?

Reliable information from another source can sometimes establish that the offeror has acted inconsistently with keeping the offer open. Analyse authority, reliability and timing. The information must objectively reach the offeree before acceptance.

Is a prescribed acceptance method always exclusive?

Wording may make the method mandatory or merely suggest a convenient route. Ask whether another method is equally advantageous and whether the offer objectively insists on exclusivity.

Why separate dispatch from receipt?

Different communication rules attach legal effect to different moments. A timeline should show sending, arrival, accessibility and reading without assuming they are legally identical. Apply the governing rule only after fixing those four events.

What does certainty require?

The agreement must identify or provide a mechanism for essential content with enough clarity for legal enforcement. Courts do not invent the commercial bargain the parties left unresolved.

How should ambiguity affect the conclusion?

Present the stronger classification, explain the rival reading and state the fact or wording that would decide between them. Conditional analysis is more accurate than invented certainty.

Study strategy

Exam move

Turn every formation problem into a table with clock time, communication, legal classification, governing rule and status of the offer. Circle words of commitment and underline terms left for approval. Analyse acceptance method and timing only after confirming an offer remained alive.

Rewrite one ambiguous message twice—once as a clear inquiry and once as a clear counter-offer—to learn which wording performs each legal function. Reconstruct each formation problem as a timestamped communication record before writing prose. Include the exact operative words, sender, recipient, medium, dispatch, arrival, accessibility, response and any event said to terminate the offer.

Beside every event, state the legal question it raises—commitment, certainty, revocation, counter-offer, prescribed method or receipt—without deciding it prematurely. Draft the strongest offer and invitation-to-treat readings from the same facts, then identify which unsettled term or retained approval distinguishes them.

For electronic messages, keep server arrival, ordinary business access and actual reading separate until the governing rule is identified. End with a formation sentence naming parties, time and terms, followed by the missing fact that could reverse it. This routine prevents a chronological story from silently substituting for legal analysis and makes later consideration and terms questions easier to locate.
