Formalities & Privity
Formalities & Privity is Week 6 of Monash University LAW5002 Principles of Contract Law A, covering two short but heavily tested edges of contract formation. Formalities asks when a contract must be in writing: most need no form at all, but a sale or disposition of land and a guarantee must be evidenced in a signed writing under the Instruments Act 1958 (Vic) s 126, with equity's part performance able to rescue an oral land deal. Privity holds that only a party to a contract can sue on it, so a third-party beneficiary generally cannot enforce a promise made for their benefit — unless a recognised route around the rule applies. All topics are examinable in the IRAC-style final.
What this chapter covers
- 011. The general rule of freedom of form — most contracts are binding without any writing at all
- 022. Which contracts need writing — a sale/disposition of land (or interest in land) and a guarantee, under the Statute of Frauds tradition and Instruments Act 1958 (Vic) s 126
- 033. Guarantee vs indemnity — only a secondary promise to answer for another's default (guarantee) needs writing; a primary, independent promise (indemnity) does not (Yeoman Credit Ltd v Latter)
- 044. The memorandum, signature, joinder of documents, and electronic form (Pirie v Saunders; Tonitto v Bassal; Electronic Transactions (Victoria) Act 2000 (Vic) ss 7, 9)
- 055. Consequence of non-compliance — the contract is unenforceable by action, not void
- 066. Part performance — equity enforces an oral land contract where acts are unequivocally referable to it (Ogilvie v Ryan; strict test in Pipikos v Trayans)
- 077. The privity rule and consideration moving from the promisee — only a party can sue (Coulls v Bagot's; Trident v McNiece)
- 088. The routes around privity — agency (The 'New York Star'), trust of the promise, insurance/statutory exceptions (Trident), estoppel, assignment/novation, and the promisee suing for the third party (Coulls)
Formalities — an oral land sale, part performance, and guarantee vs indemnity
- +1Issue: (a) is a sale of land enforceable without a signed memorandum; (b) does part performance rescue it; (c) is Rob's promise a guarantee (needs writing) or an indemnity (does not)?
- +2(a) A sale or disposition of land is unenforceable by action unless there is a note or memorandum in writing signed by the party to be charged (Instruments Act 1958 (Vic) s 126). Theo seeks to enforce against Priyanka, who signed nothing, so the contract is unenforceable against her — but unenforceable, not void.
- +2.5(b) Equity can enforce an oral land contract where the plaintiff's acts are unequivocally referable to it (Ogilvie v Ryan), on a strict test (Pipikos v Trayans). Theo took possession and built a shed and fencing — acts explicable only by a contract to buy the land — so part performance is likely made out.
- +1.5Counter-argument on (b): the $26,000 deposit alone would not be enough, because payment of money is equivocal; Theo must rely on the possession and building, not the deposit.
- +1.5(c) Only a guarantee (a secondary promise to answer for another's default) needs writing; an indemnity (a primary, independent obligation) does not (Yeoman Credit Ltd v Latter). Version (1) "I'll see that you are paid" is a primary/independent undertaking, so it is an indemnity enforceable orally.
- +1(c) cont.: Version (2) "if Theo doesn't pay, I will" is a secondary promise conditional on Theo's default, so it is a guarantee and is unenforceable unless in signed writing (s 126).
Key terms
- Formalities
- Requirements as to the form of a contract. The general rule is freedom of form, but the Statute of Frauds tradition — in Victoria, Instruments Act 1958 (Vic) s 126 — requires certain contracts to be evidenced in writing signed by the party to be charged.
- Instruments Act 1958 (Vic) s 126
- The Victorian writing requirement: a sale or disposition of land (or an interest in land) and a guarantee are unenforceable by action unless there is a note or memorandum in writing signed by the party to be charged or their agent; s 126(2) allows electronic form.
- Guarantee vs indemnity
- A guarantee is a secondary promise to answer for another's default and must be in signed writing; an indemnity is a primary, independent obligation and needs no writing (Yeoman Credit Ltd v Latter). The test is whether the promisor's liability is secondary or primary.
- Memorandum / signature / joinder
- The note or memorandum records the essential terms and must be signed by the party to be charged; separate documents may be joined where they refer to one another (Pirie v Saunders; Tonitto v Bassal). Writing and signature may be satisfied electronically (Electronic Transactions (Victoria) Act 2000 (Vic) ss 7, 9).
- Unenforceable (not void)
- Non-compliance with s 126 makes the contract unenforceable by action against the party who did not sign — the contract still exists and is not void or illegal, which is why part performance can revive enforceability.
- Part performance
- An equitable doctrine allowing an oral land contract to be enforced where the plaintiff's acts are unequivocally referable to the alleged contract (Ogilvie v Ryan), on a strict test (Pipikos v Trayans). Taking possession and building/renovating usually suffices; a bare deposit usually does not.
- Privity of contract
- Only a party to a contract can sue or be sued on it, so a third-party beneficiary generally cannot enforce a promise made for their benefit (Coulls v Bagot's; Trident v McNiece). It is reinforced by the rule that consideration must move from the promisee.
- Routes around privity
- Recognised ways a third party (or the promisee) can obtain a remedy despite privity: agency under an exclusion clause (The 'New York Star'), a trust of the promise, insurance and other statutory exceptions (Trident), estoppel, assignment/novation, and the promisee suing for the third party's benefit and seeking specific performance (Coulls, Windeyer J).
Formalities & Privity FAQ
Does a contract have to be in writing to be valid?
Usually not — most contracts are fully binding even if made orally. The main exceptions in Victoria are a sale or disposition of land (or an interest in land) and a guarantee, which under the Instruments Act 1958 (Vic) s 126 must be evidenced in a note or memorandum signed by the party to be charged. Even then, non-compliance makes the contract unenforceable by action, not void, and equity's part performance doctrine can enforce an oral land contract where the buyer's acts — such as taking possession and building — are unequivocally referable to it (Ogilvie v Ryan; Pipikos v Trayans).
If a contract benefits me but I did not sign it, can I sue on it?
Generally no. Under the privity rule, only a party to a contract can sue on it, so a third-party beneficiary cannot enforce a promise made for their benefit (Coulls v Bagot's; Trident v McNiece), and consideration must move from the promisee. But several routes may help: agency protection under an exclusion clause (The 'New York Star'), a trust of the promise, insurance and other statutory exceptions (Trident, read narrowly), estoppel, or assignment/novation. The contracting party can also sue to enforce the promise for your benefit and seek specific performance (Coulls, Windeyer J).
Can AI help me with Formalities & Privity in LAW5002?
Yes, as a study aid. An AI tutor like Sia can explain s 126, walk through the guarantee-versus-indemnity distinction and the part-performance test step by step, and take you through worked IRAC problems so you understand why an answer is right — it will not write your assignment or sit your exam for you, and cannot promise a mark or a pass. The most recent past exam was open book but did not permit generative AI in the exam room, so use AI to build understanding beforehand and confirm the current rules on Moodle.

Exam move
Treat this topic as two quick decision trees you can run on autopilot. For formalities, always ask first whether the contract is land or a guarantee; if it is neither, form is irrelevant. If it is caught by s 126, look for a signed memorandum by the party to be charged, and if there is none, test part performance — remembering that possession plus building or renovating usually satisfies the unequivocally-referable test (Ogilvie v Ryan; Pipikos v Trayans) while a bare deposit does not, and that the contract is unenforceable rather than void. Keep the guarantee-versus-indemnity line sharp on the actual words used (Yeoman Credit Ltd v Latter). For privity, start every third-party problem from the general rule (Coulls; Trident) and consideration moving from the promisee, then run the exceptions in order — agency, trust of the promise, insurance/statutory, estoppel, assignment/novation — and finish with the promisee's own action for the third party. Practise on short fact scenarios in IRAC, naming the case or section for every step and arguing both sides before you conclude, because the problem-question marking rewards identifying the source of each principle.
