Selling a Site to Developers: What the Agency Agreement Fixes Before Any Buyer Appears

Selling a Site to Developers: What the Agency Agreement Fixes Before Any Buyer Appears

General information for South Australian landowners only. This is not legal, conveyancing, valuation or agency advice. Route the wording of any sales agency agreement, contract of sale or disclosure statement to your own lawyer or conveyancer; route price and market evidence to your registered land agent and, if you want an independent figure, to a qualified valuer; route the tax treatment of a sale to your registered tax agent.

You have three or four ways to run this sale and no obvious way to rank them. The local agent who sold every house in your street wants to list it. A commercial agency says a development site needs a campaign with a closing date. A developer has written to you directly and would rather not compete. Someone has said "expressions of interest" as though that settled it.

Most owners rehearse the negotiation. But by the time an offer arrives, the terms governing what you may do with it were set weeks earlier, when you knew least about who wanted the land. That document is the sales agency agreement. (What you sell — raw land, or land with a consent — is covered in selling a block with DA approval.)

Nothing starts until you sign, so the agreement is written at your point of least information

An agent cannot act for a vendor unless a sales agency agreement has been signed, and before entering into one the agent must give the vendor a written guide to their rights and obligations (source: Law Handbook SA – Selling a home). That guide is Form R1, approved under section 20(2) of the Land and Business (Sale and Conveyancing) Act 1994.

Form R1 lists what every sales agency agreement for residential property must include: the duration; the agent's genuine estimate of the sale price and the price you would accept, each as a single figure; the manner of sale; your termination rights; whether the agent may accept an offer on your behalf; and "the circumstances in which the agent will be entitled to receive commission... and also the circumstances in which the sale may not be attributable to the agent" (source: Form R1).

Every line there is a lever, and every one is pulled before a buyer is known. Settle one thing first, though: those requirements are written for residential property, and development sites arrive in different forms — an old house on a deep block, vacant land, something in commercial use. Which of them attach to a particular parcel is for your lawyer or conveyancer, and worth asking before you are handed a form.

Sole agency: what triggers commission, settled before a buyer exists

Form R1 records that sole agency agreements are the most common form of agreement in South Australia, and that your agent will most likely suggest one. Under a sole agency the agent has the exclusive right to sell, and the commission entitlement can arise whether or not the agent is the one who actually sells — including, in the guide's own words, where the vendor sells the property themselves. Form R1 is equally explicit that "this will depend on the wording of the agreement" (source: Form R1 – Sales Agency Agreements). Which sales your agreement captures is what that wording decides, and reading it is what your lawyer or conveyancer is for.

That matters most in the situation development-site owners keep landing in: a buyer who arrived before the agent. Whether someone who approached you directly sits inside or outside the commission entitlement is not answered by their offer letter. It turns on the clause describing when a sale may not be attributable to the agent — a term to raise, and have read, before signing.

The clock: how long the land stays committed

Duration is a required term, and for the sale of residential land the Act caps it: the agreement runs for a fixed maximum period, after which a new one must be entered into, and any shorter period may be agreed (source: Law Handbook SA – Selling a home).

The extension mechanics deserve a diary entry. The Law Handbook describes a further extension of capped length, permitted once rather than as a rolling series, and conditions it on the agent first: a Notice of Expiry given by the agent within a prescribed window before the expiry date, and an extension signed by both agent and vendor. Where such a notice is given and the vendor does not respond, it says the agreement is automatically extended, for longer than the original term — and it records a right belonging to you, that during an extension the vendor may terminate on short written notice (source: Law Handbook SA – Selling a home).

Note the date on that page, which is years old. The current Form R1 describes extension only as something you and your agent may decide on towards the end of the term, and mentions no Notice of Expiry and no consequence of silence (source: Form R1 – Sales Agency Agreements). The two do not describe the same machinery. Which governs your agreement, and whether a notice you receive was given inside the prescribed window, is for your conveyancer — not something to concede by staying silent.

So the question is not "how long do I want to try?" It is: if the campaign does not produce the buyer I expected, what do I want to be free to do next, and when? Holding costs run the whole time — one input behind subdividing or selling as-is.

The number you name before anybody has bid

Form R1 is blunt that the agent's genuine estimate "is not a valuation" and "is in no way any guarantee that you will receive that price in the market place"; the agent must also provide comparable sales and any other information relied on to support it (source: Form R1 – Sales Agency Agreements).

Where those requirements attach to the sale, the two figures then constrain the campaign. Form R1 sets a prescribed minimum advertising price: an advertised likely sale price cannot be lower than the higher of the amount you specify as acceptable and the amount the agent has estimated; and at auction the reserve is capped by reference to your acceptable price, which you cannot then increase (source: Form R1 – Sales Agency Agreements). Legislation separately prohibits advertising property below the estimated selling price to attract a large number of buyers and artificially create interest, and an agreement cannot be amended before an auction, or terminated early and replaced, to lift the price (source: Law Handbook SA – Selling a home).

That is the asymmetry in its clearest form. A developer's number is built backwards from what can be built and what building it costs — see whether a developer's offer is a fair price. Yours goes into a form first.

Manner of sale is a term of the agreement, not a marketing preference

Sell by auction and there is no cooling-off period for the purchaser, and the Form 1 must be available at the offices of the agent or auctioneer for a set number of business days beforehand, and at the venue for a set period immediately before it starts (source: Law Handbook SA – Cooling-off period; Law Handbook SA – Form 1). Outside auction a purchaser has a short statutory cooling-off window, which a vendor or agent may ask to be waived as a condition of sale — a waiver requiring a solicitor's certificate confirming the purchaser was advised of the ramifications (source: Law Handbook SA – Cooling-off period).

Whether your buyer holds that right at all is worth naming, because a development-site buyer is very often a company. The same page says bodies corporate purchasing residential land may exercise the right to cool off, and draws "residential land" by the number of places of residence on the land, by whether vacant land is land on which a residence can lawfully be constructed, and by an upper limit on area (source: Law Handbook SA – Cooling-off period). Whether a parcel sits inside that definition is determined on the facts of the land — for your conveyancer, not an inference from the buyer's letterhead. Note that page's revision date, older than the Form 1 page beside it.

Run an expressions-of-interest or tender campaign and a different question appears. An EOI is usually not a binding contract to do the deal, but many include clauses intended to bind — confidentiality, costs of participation, exclusivity or standstill, or obligations to negotiate in good faith (source: Sprintlaw – Expressions of Interest). Where an owner runs that kind of process, the rules of it are a matter for the documents — which is an advantage only if somebody on your side has drafted them.

Then the variable no format solves: how much exposure the site can afford. A campaign that closes without a sale is visible to every buyer who watched it. Off-market avoids that and gives up the competitive tension a closing date exists to create. No general ranking survives contact with a specific site, buyer pool and timeline. The useful question is which you can withdraw from, and on what notice.

What the campaign will require you to disclose

The guidance here is written around the sale of a house, so carry the caveat forward: whether and in what form these obligations attach to a particular parcel is for your lawyer or conveyancer. On its own terms, a vendor must provide a Form 1 to the purchaser, and where an agent has been hired it is the agent's responsibility to prepare it and make all the inquiries necessary to do so accurately — the vendor's, to give the agent correct information (source: Law Handbook SA – Form 1).

Both halves carry consequences, and a remedy sits between them. Inaccuracies make a Form 1 defective, so it does not trigger the cooling-off period — though the same guidance says a vendor can alter the Form 1 to correct inaccuracies, with the cooling-off period then commencing on the date the corrections are made. Where a Form 1 is not served, or is inaccurate, the purchaser may rescind at any time up until settlement; after settlement the page describes a purchaser applying to a court to set the contract aside or seeking damages, and records that failing to provide a Form 1 in time, or providing an incomplete or incorrect one, is an offence (source: Law Handbook SA – Form 1). Whether a given inaccuracy can be cured that way is for your conveyancer.

From March 2021, Form 1 notices must contain updated information on the zone, subzone and overlay in which the land is located, in line with the SA Planning Code, with further updates later that year, so the statement must be prepared on the most current form from the SA Integrated Land Management System (source: Law Handbook SA – Form 1). Where those requirements apply, the planning position of the land is in the sale documents — and which way your parcel is treated is the question the opening section sent to your conveyancer.

The levers you actually hold

• Costs and rebates. Everything charged separately, including advertising and marketing, must be specified with the amounts, the times for payment, and whether a third party provides it, along with the nature, source and, if known, the value of any rebate the agent expects on those services. Form R1 says you are within your rights to negotiate a benefit from those rebates, and that you can include a clause requiring the return to you of some or all of a rebate once paid (source: Form R1 – Sales Agency Agreements).

• Authority to accept. The agreement must specify whether the agent may accept an offer on your behalf, and if an agent signs a contract of sale on your behalf that contract binds you. The same guide records the other side of the switch: if you retain the right to accept an offer yourself, your property cannot be sold unless you agree to it — and where you do give the agent the authority, the agreement should state clearly when and in what circumstances it applies (source: Form R1 – Sales Agency Agreements).

• Termination. Form R1 says an agreement may limit your termination rights or provide for costly termination fees, and may deem termination to occur if you sell privately or through another agent — in which case, depending on the agreement, the first agent may still be entitled to a commission.

• Your own evidence. Ask how the estimate was reached, and engage a qualified valuer for an independent figure, which Form R1 says you may do.

Before you sign

The longest tie-ups are often elsewhere — a conditional offer or an option (call option agreements over land in SA), or a joint sale with neighbours and its split (selling with neighbours by amalgamation). But the agency agreement comes first.

So the questions worth putting to your conveyancer or lawyer, in writing, before signature: is this a sole agency, and in what circumstances is a sale not attributable to you? Which parties are carved out? What are my termination rights, and what do they cost? What is the term, on what basis can it be extended, and which document governs that? What am I charged separately for, and what rebates do you expect? Take the answers to your lawyer or conveyancer before you sign.

Cyberate PM works on the owner's side of that table. We do not sell land, value it, or advise on the law — a registered land agent runs the campaign, your lawyer or conveyancer reads the documents, a qualified valuer gives an independent figure. We coordinate the sequence: the planning and site position understood, the owner's own valuer, accountant and quantity surveyor engaged and their figures in one place, the right people briefed before the first document is signed — so the agreement reflects a decision rather than making one.
