Can a Verbal Agreement Be Binding?
When spoken promises may form an enforceable contract
A contract does not always need to be a formal signed document. A verbal agreement may be binding when the legal requirements for a contract are satisfied, but some transactions must be evidenced in writing and oral terms can be difficult to prove.
Key takeaways
- Courts may enforce agreements made orally, in writing, by conduct, or through a combination of these.
- The parties still need an identifiable agreement, consideration, intention and sufficiently certain and complete terms.
- Victorian law requires signed written evidence for some agreements, including many guarantees and contracts concerning interests in land.
- Emails, messages, invoices, bank records, notes and witness evidence can help prove what was agreed.
What makes an agreement a contract?
Calling something an “agreement” does not decide whether it is legally enforceable. Courts generally examine whether there was:
- a clear offer and acceptance, objectively assessed;
- consideration—something of value exchanged—unless the promise is made by deed;
- an intention to create legal relations;
- sufficiently certain and complete terms;
- parties with legal capacity; and
- a lawful purpose.
The whole interaction matters. A contract may be wholly oral, wholly written, partly oral and partly written, or inferred from conduct.
Why are verbal contracts risky?
The main problem is usually proof. People may remember different words, prices, deadlines or conditions. A court decides the dispute from admissible evidence, not simply from which person sounds more confident.
Useful evidence may include contemporaneous notes, text messages, emails, calendar entries, quotes, invoices, receipts, bank transfers, recordings made lawfully, later conduct and independent witnesses. A message sent immediately after a conversation—“Confirming that we agreed…”—can expose misunderstandings before work begins.
When is writing required in Victoria?
Section 126 of the Instruments Act 1958 (Vic) restricts court action on certain promises unless the agreement, or a memorandum or note of it, is in writing and signed by the person against whom enforcement is sought or an authorised person. It covers many promises to answer for another person's debt or default and contracts for the sale or other disposition of land or an interest in land.
Other legislation can impose form, signature, disclosure or document requirements for particular transactions, including consumer credit and some property dealings. Electronic communications and signatures may sometimes satisfy a writing requirement, but that depends on the legislation and circumstances.
Exceptions and equitable doctrines can be complex. Do not assume that performance or payment automatically fixes a failure to comply with a statutory formality.
Common misunderstandings
“No signature means no contract”
Incorrect as a general rule. Acceptance may be spoken or inferred from conduct, unless the parties or the law require signature.
“A handshake proves every term”
A handshake may support the existence of an agreement, but it does not independently prove the price, scope, deadline or conditions.
“A quote is always the contract”
A quote may be an offer, part of the contract or only preliminary information. Its wording and the later communications and conduct matter.
Practical example
A homeowner verbally accepts a gardener's offer to perform specified work for $900 on a particular date. The gardener buys materials and the homeowner later sends a text confirming access arrangements and the price. A court could find a contract from the conversation, message and conduct.
If the parties never agreed what work was included or how the price would be calculated, the alleged terms may be too uncertain. If the supposed agreement instead concerned a transfer of land, statutory writing requirements would also need careful consideration.
What to do after a verbal agreement
- Write down the exact terms, date, place and people present while the conversation is fresh.
- Send a neutral written confirmation and ask the other party to correct anything inaccurate.
- Keep all related documents, messages and payment records.
- Do not secretly record a private conversation without checking the applicable surveillance law.
- If a dispute arises, identify the remedy sought and any limitation period before delaying.
- Get legal advice for high-value, land, guarantee or technically regulated transactions.
