A supplier agrees to deliver materials at a fixed price. A business partner promises to contribute capital next month. A landlord says they will cover maintenance costs. These conversations happen daily across Victoria, often sealed with nothing more than a handshake and mutual trust. The question of whether these verbal agreements hold legal weight comes up regularly in our business agreement review discussions, and the answer is more complicated than most people expect.

Verbal Agreements: Legally Binding but Hard to Prove

Victorian law does not require most commercial agreements to be written down. A verbal contract can create binding legal obligations if certain conditions are met. Both parties must have made an offer and acceptance. There must be an exchange of value (money for goods, services for payment). Both sides must have intended to create a legal relationship rather than a casual arrangement. And the terms must be clear enough that a court could enforce them.

The catch is proving any of this happened.

When two people disagree about what was promised, courts must rely on evidence. Without a written document, that evidence comes from memory, context, and whatever supporting materials exist. Text messages, emails, witness statements, and banking records all become relevant. But memory is unreliable. Two honest people can genuinely recall the same conversation differently.

This creates a practical problem even when an agreement is technically valid. The cost of proving what was said can exceed the value of the dispute itself.

Where Victorian Law Demands Writing

Some agreements must be in writing to be enforceable, regardless of how firm the handshake was. Under the Sale of Land Act 1962 (Vic), any contract for the sale, transfer, or disposition of real estate requires written documentation. Furthermore, the Domestic Building Contracts Act 1995 (Vic) requires that contracts for major domestic building work be in writing to be valid. A verbal agreement to sell a property, no matter how specific the terms, cannot be enforced in court.

This catches people out regularly. A property developer verbally agrees to purchase land. They proceed with due diligence, spend money on surveys and reports, then the seller backs out. Without a written contract, the developer has no legal claim to the property, even if they can prove the conversation occurred.

Similar requirements apply to guarantees. If someone verbally promises to guarantee another person's debt, that guarantee is generally unenforceable unless it is in writing. Business owners should review red flags in personal guarantees before signing any written version.

The Commercial Contract Review Question

A common scenario: a business owner operates for years on verbal arrangements with suppliers, customers, or partners. Everything works until it does not. A dispute arises, and suddenly the lack of documentation becomes expensive.

We provide commercial contract review services that are not just about checking documents that already exist. We also focus on identifying which relationships need written agreements in the first place. A supplier relationship that has operated smoothly for five years on verbal terms still carries risk. If the supplier changes ownership, or if a key contact leaves, the informal understanding may not survive. We offer fixed fee pricing for our contract reviews to provide certainty and transparency for your business.

Written contracts do more than record what was agreed. They force both parties to think through scenarios they might not have discussed. What happens if delivery is late? Who bears the cost if materials are defective? What notice is required to end the arrangement? These questions rarely come up in handshake conversations but matter enormously when problems occur.

Business Contract Review: What to Document

Not every business interaction needs a formal contract. Buying office supplies does not require a written agreement. But certain relationships carry enough risk to warrant documentation:

  • Ongoing supplier arrangements with customised pricing or terms
  • Partnership or joint venture agreements of any kind
  • Employment arrangements beyond standard award conditions
  • Lease agreements for premises or equipment
  • Franchise relationships
  • Any agreement involving payment over time or deferred obligations

For commercial leases specifically, the Retail Leases Act 2003 (Vic) imposes particular requirements. A verbal lease for retail premises creates problems for both landlord and tenant. The Act requires specific disclosures and documentation, and failure to comply can affect enforceability and create statutory liabilities.

Victoria's property disclosure laws under the Sale of Land Act 1962 took effect to ensure transparency, adding another layer of documentation requirements for property transactions.

When Verbal Agreements Make Sense

Written contracts are not always practical or necessary. Small, one-off transactions between trusted parties often proceed verbally without incident. The cost and time involved in documenting every business interaction would be prohibitive.

The decision to formalise an agreement in writing should reflect the risk involved. Consider the dollar value at stake, the complexity of the arrangement, the length of the relationship, and the consequences if things go wrong. A $500 one-time purchase from a supplier you have used for years may not need a contract. A $50,000 ongoing supply arrangement almost certainly does.

Even when a full written contract seems excessive, a simple email confirming the terms of a verbal discussion creates useful evidence. "Just to confirm our conversation today: you will supply 200 units at $45 each, delivered by 15 March, payment within 30 days of invoice." This takes thirty seconds and provides something to point to if memories later differ.

Enforcing a Verbal Agreement

If you find yourself needing to enforce a verbal agreement, the burden of proof falls on you. Courts will look at all available evidence to determine whether an agreement existed and what its terms were.

Helpful evidence includes:

  • Text messages or emails discussing the arrangement
  • Witness statements from people present during discussions
  • Banking records showing payments consistent with the claimed terms
  • Prior course of dealing between the parties
  • Industry custom and practice for similar arrangements

The Victorian Civil and Administrative Tribunal (VCAT) handles many business disputes involving smaller amounts, with a less formal process than courts. But even VCAT requires evidence. "We had a deal" is not enough without something to support it.

Government guidance on contract review processes emphasises the importance of clear documentation throughout any commercial relationship.

Practical Steps for Victorian Businesses

For existing verbal arrangements that have worked well, consider formalising them now rather than waiting for a dispute. A written agreement does not signal distrust. We believe it protects both parties by recording what everyone already understands.

For new arrangements, establish a threshold above which written contracts are standard practice. This might be any arrangement worth more than $5,000, or any ongoing relationship, or any deal with a new party you have not worked with before.

When buying or selling a business, the documentation requirements increase significantly. Business sale contracts involve multiple components that verbal agreements simply cannot address adequately.

A business contract review before signing identifies risks and missing protections. It costs far less than litigation after a relationship breaks down.
