Offer, Acceptance & Consideration in Contract Law Assignments

What is Offer, Acceptance & Consideration in Contract Law Assignments

If you're staring at a contract law assignment with no idea where to start, you're not alone. Offer. Acceptance. Consideration. These three words are enough to trip up any law student in Australia. But no need to worry anymore, this guide will simplify these concepts for you.

But let's first understand what a contract is in the eyes of the Australian law courts. So, it's a legally binding agreement between two or more parties based on the commitment to do or not do certain things. In case the agreement gets breached by either side, it can be enforced in a court. With that brief, let's start learning offer, acceptance and consideration in detail. We'll also see how to use them in a contract assignment.

What Is an Offer in Contract Law?

An offer is a proposal from one person (the offeror) to another (the offeree). But for an offer to be valid, it needs to be:

• Clear and specific
• Communicated to the other person
• Intended to be binding if accepted

Simple? But students often get it confused with Invitation to Treat.

Offer vs Invitation to Treat

An invitation to treat is just an invitation to start negotiating. It's not an offer. And it cannot be "accepted" to form a contract. Let's say when a shop puts a jacket in the window with a $50 price tag, is that an offer? Actually no. It's an invitation to treat until the customer picks it up and takes it to the till. That's when it becomes an offer, as now both parties are equally willing to do something. Basically, displayed goods, advertising, and price lists are not offers. They’re almost always invitations to treat.

How Can an Offer Come To an End

It's interesting to know that an offer doesn't last forever. It can end in several ways:

• Revocation: the offeror takes it back (must happen before acceptance)
• Rejection: the offeree says no
• Counter-offer: the offeree changes the terms
• Lapse of time: the offer expires
• Death: of either party

Unilateral vs Bilateral Offers

A bilateral offer is the normal kind. One person offers, another accepts. Both sides make promises. But a unilateral offer is where one party makes a promise in exchange for an action. The classic example is a reward: "I'll pay $500 to anyone who returns my dog."

What Is Acceptance in Contract Law?

Acceptance is when the offeree says "yes" and means it. But there are certain rules:

• It must be communicated to the offeror
• It must be made while the offer is still open
• It must match the offer exactly

The Mirror Image Rule and Counter-Offers

Acceptance must be a perfect mirror of the offer. If you change anything, that's not acceptance. It's a counteroffer and wipes out the original offer entirely.

What is Acceptance by Conduct?

It’s the acceptance done through actions. Let’s say a company sends you goods and you use them, so your action now amounts to acceptance.

The Postal Rule And Does It Apply to Emails?

The postal rule says that acceptance takes effect the moment you post the letter, not when the other person receives it. In short, the contract is formed at the post office, even if the letter is delayed or lost in the mail.

But that’s not the same with emails. As of the Electronic Transactions Act 1999 (Cth), the acceptance takes effect when it is received.

Can Silence Be Acceptance Under Australian Law?

No. Silence cannot be a form of acceptance. You cannot force someone into a contract by telling them their silence will mean they agree. Acceptance has to be an active, communicated act.

What Is Consideration in Australian Contract Law?

Consideration is the act of agreeing to an offer with something of value brought for exchange. Without it, you just have a promise, not a real contract. The traditional definition that still gets cited in Australian courts comes from the English case of Currie v Misa (1875). It defines consideration as "some right, interest, profit, or benefit" going to one party against "some forbearance, detriment, loss, or responsibility" suffered by the other.

Types of Consideration

There are three types, and your assignment might test any of them.

1. Executory Consideration: A promise to do something in the future. "I'll paint your fence next Saturday if you pay me $300." Neither party has done anything yet, but the exchange of promises is enough to form a contract.
2. Executed Consideration: One side has already performed. "I'll pay $200 if you find my lost bike." When you find the bike, your act is the consideration.
3. Past Consideration: This is the consideration that was given before the promise was made, so it doesn't count. “If you fix your neighbour's fence out of goodwill, and then a week later they promise to pay you $500 for it, that promise is not enforceable.”

Sufficient vs Adequate

A consideration becomes sufficient when it has some real value in the eyes of the law. Something physical like money, assets, or promises. Adequate consideration refers to the fair market value of the exchanged good. But it is not necessary.

So if someone agrees to sell their car worth $20,000 for $1, that is still valid consideration. Courts in Australia do not ask whether the deal was a good one. They just ask: was something of value exchanged?

Promissory Estoppel

This can be used as a sword in Australia if one party tries to break a promise after the other has suffered a financial loss. The landmark case that is often cited by many law assignment help services is Waltons Stores (Interstate) Ltd v Maher (1988) 164 CLR 387. Maher owned property in Nowra, and Waltons Stores wanted to lease it. They wanted Maher to demolish existing buildings and build new ones to their specifications. Maher started doing it as expected, while Waltons had changed their mind in silence. The High Court then ruled in Maher's favour, and Waltons Stores was estopped from denying the existence of their obligations.

How to Write an Australian Contract Law Assignment Using IRAC

You now know the substantive law. Here's how to put it together in an assignment.

Issue

Begin by identifying the legal problem. Read the question carefully. Ask yourself: what is actually being disputed here? Is there a valid contract at all? Was the offer validly accepted? Was there real consideration?

Example: "The issue is whether a binding contract was formed between A and B when B sent an email accepting A's written offer on March 3."

Rule

State the legal rule. Cite an Australian case or statute where possible.

Example: "As per the Electronic Transactions Act 1999 (Cth) states that an electronic communication is received when it enters the recipient's information system.”

Application

Don’t state the rules here. Put them side by side with the facts and argue through them.

Example: "Here, A's written proposal had clear terms and was communicated directly to B, satisfying the requirements of a valid offer. B's email response accepted all terms without modification, satisfying the mirror image rule. Under the Electronic Transactions Act 1999 (Cth), the acceptance took effect when A's system received B's email.”

Conclusion

Here, all you have to do is state your verdict in short and simple language.

Example: "On these facts, a valid contract was formed between A and B at the time A's system received B's acceptance email on 3 March."

Final Thoughts

Contract law assignments feel overwhelming at first with all those terminologies, cases and problem questions. But here's what you need to remember.

Once you understand what offer, acceptance, and consideration actually mean, every problem question becomes a checklist. Just apply the correct law, and you’re good to go. Use IRAC to back up every point with an Australian authority.
