An Australian lawyer engagement letter, and the costs rules it must satisfy

The letter that opens a matter is also the document that decides how it closes: what was in scope, what the client owes, and who was allowed to give instructions.

Fee arrangements in a law practice are not purely a matter of contract. What has to be communicated, and in many cases put in writing before the work begins, is governed by the costs disclosure rules in your state or territory — and the consequences of getting it wrong run from an unenforceable fee to a regulatory complaint.

Get started

The template below is written as a client-facing letter rather than a retainer agreement in legalese, because a client who reads it is a client who cannot later say they did not understand it. Some firms call it a letter of engagement or a retainer letter; the rules above apply whatever it is called.

What a legal engagement letter has to settle

  1. 1

    Who the client is, and who is not

    In a company matter, the client is usually the company rather than the director sitting in front of you. In a family matter, it is one spouse. Saying so in writing prevents the most common conflict problem there is.

  2. 2

    The scope of the retainer, and its end

    The matter you are retained for, the steps included, and what is excluded — appeals, enforcement, tax advice, other jurisdictions. Say what event ends the retainer, because a matter that never formally ends is a limitation period problem waiting to happen.

  3. 3

    Fees, in the form the rules require

    The basis of the fee — hourly, fixed, contingency where permitted — the rates of everyone who will work on it, what disbursements are charged, and how often you bill. The floor is set by the costs disclosure rules in your state or territory; your own regulator may require more.

  4. 4

    Money held on account

    How retainers and client money are held, which account they sit in, how they are applied to invoices, and what happens to the balance when the matter ends. This is the clause your regulator will read first.

[Firm letterhead]

[Date]

[Client name]
[Client address]

Dear [Client contact],

Thank you, and who we act for

Thank you for instructing [Firm name]. This letter sets out the terms on which we will act. Our client in this matter is [Client name] and only [Client name]. We do not act for any related company, director, shareholder or family member unless we confirm that separately in writing.

The matter, and its scope

You have asked us to [describe the matter and the outcome sought]. Our retainer covers [list the steps included].

It does not cover [appeals, enforcement, tax advice, advice on the law of another jurisdiction, or any other matter]. If you would like us to act on any of those we will confirm a separate scope and fee first.

Who will do the work

[Name] will have day-to-day conduct of the matter, supervised by [Name]. We may involve others where it is more efficient, at the rates set out below. We will tell you if the person with conduct changes.

Fees, disbursements and billing

Our fees are charged [on a fixed basis of [amount] / at hourly rates of [rates]] in Australian dollars, in units of [number] minutes. Disbursements — [filing fees, experts, searches, travel] — are charged in addition, as incurred.

We invoice [monthly / on completion of each stage]. Invoices are payable within [number] days. We will give you an estimate for the matter as a whole and update it if it changes materially, but an estimate is not a cap unless this letter says it is.

Money held on your behalf

We ask for [amount] on account before we begin. Money you pay us on account is held in our [client / trust] account and applied to invoices as they are issued. Any balance is returned to you when the matter ends. [Interest is dealt with as follows.]

Conflicts and confidentiality

We have checked for conflicts of interest and are not aware of any. If one arises, we will tell you promptly and may have to stop acting. Everything you tell us is confidential and privileged, subject to the limited circumstances in which the law or our professional obligations require disclosure.

Ending the retainer

You may end this retainer at any time by telling us in writing. We may stop acting where we have good reason and reasonable notice, including where invoices remain unpaid or where a conflict arises. In either case fees and disbursements incurred to that point remain payable, and we will tell you what steps remain outstanding on the matter.

Your records and ours

At the end of the matter we will return your documents on request and keep our file for [number] years, after which it is destroyed. We hold your information in accordance with the Privacy Act 1988. If you are not happy with our service, [describe the complaints procedure and the regulator's contact details].

Agreement

Please sign and return a copy of this letter. If you have any question about any part of it, ask before you sign.

Costs disclosure for Australian lawyers

There is no single national rule. The Legal Profession Uniform Law has applied in New South Wales and Victoria since 1 July 2015 and in Western Australia since 1 July 2022. Queensland, South Australia, Tasmania, the ACT and the Northern Territory sit outside that scheme, and a letter used there must be checked against local legislation.

Under section 174 of the Uniform Law, disclosure is made in writing, before or as soon as practicable after the practice is retained, and covers how costs will be calculated and an estimate of total legal costs. When circumstances change, updated disclosure is due as soon as practicable.

The $750 and $3,000 thresholds

No disclosure is required where total legal costs, excluding GST and disbursements, are unlikely to exceed $750. Between $750 and $3,000, the standard disclosure form in Schedule 1 of the Uniform General Rules may be used instead of full disclosure.

Rights the client must be told

Disclosure also tells clients they may negotiate a costs agreement and a billing method, receive a bill and request an itemised one, and seek the local regulator's help in a dispute about legal costs.

Commercial clients differ

Costs disclosure is not required for commercial or government clients. The letter should still state the costs basis, because the exemption removes a statutory duty, not the need for an agreed fee.

What non-disclosure costs

Without proper disclosure, any costs agreement is void, the client need not pay until costs are assessed or the dispute determined, and the failure can amount to unsatisfactory professional conduct. No-win-no-fee agreements must also be signed.

Where legal engagement letters fail

Ambiguous about who the client is

The director assumes you act for them personally. When the company's interests and theirs diverge, that assumption becomes a conflict and a complaint.

An estimate treated as a cap

If the letter does not distinguish the two, the client will, and they will do it after the bill arrives.

No stated end

A retainer that never ends leaves you owing duties on a matter you stopped thinking about years ago.

Questions law practices ask

Is a written engagement letter mandatory?

It depends on where you practise and on the size and type of the matter. The starting point is the costs disclosure rules in your state or territory, and several jurisdictions set written requirements of their own — under the Legal Profession Uniform Law, for example, costs must be disclosed in writing once they are likely to exceed $750. Check your own regulator before relying on anything here.

Does it need to be signed to be effective?

A signed copy is much stronger evidence, and in some jurisdictions the rules effectively require the client's agreement in writing. Where a client proceeds without signing, confirm in writing that the terms apply and keep the acknowledgement.

Can one letter cover several matters for the same client?

A standing terms-of-business letter plus a short matter-specific scope letter is a common arrangement and works well. What does not work is one letter from four years ago describing a different matter.

What about contingency or conditional fees?

They are permitted in some jurisdictions and for some matter types and prohibited in others, with their own disclosure requirements. This template does not attempt to cover them; take advice specific to your jurisdiction.
