Best interests duty for financial advisers: what it is, with a worked example

If you are a financial adviser in Australia, the best interests duty is the obligation that sits underneath almost everything you do. It is not a slogan. It is a specific legal duty in the Corporations Act, and when your advice is reviewed later, the question is rarely whether you meant well. It is whether you can show what you did. This article walks through what section 961B actually requires, the safe harbour steps that let you prove you met it, how it differs from the mortgage broker version, and why the file note is the document that carries the weight.

What is the best interests duty?

The best interests duty lives in section 961B(1) of the Corporations Act 2001. In plain terms, it requires a provider who gives personal advice to a retail client to act in the best interests of the client in relation to that advice. It is a duty about the process you follow, not a promise about the investment outcome. You can meet the duty and still have the market move against the client. The point is whether you ran a sound, client-first process at the time the advice was given.

The best interests duty does not stand alone. It runs alongside two related obligations that apply every time you give personal advice: s961G, the appropriate advice duty, which requires the advice itself to be appropriate for the client's relevant circumstances, and s961J, the conflicts priority rule, which requires you to give priority to the client's interests where a conflict exists between the client and you or an associate. ASIC's guidance on all of this sits in Regulatory Guide 175. A failure on the best interests duty and a failure on appropriate advice tend to travel together, because the same missing investigation causes both.

The safe harbour steps in s961B(2)

Here is the part that matters most in practice. Section 961B(2) sets out a list of steps, and if you can prove you took all of them, you are taken to have satisfied the duty. This is the so-called safe harbour. It is a statutory defence, so the burden is on you to prove you did each step. The steps are:

1. (a) Identify the client's objectives, financial situation and needs as disclosed to you through their instructions.
2. (b) Identify the subject matter of the advice the client is seeking, whether they set it out expressly or it is implied, and identify the objectives, situation and needs that would reasonably be considered relevant to that subject matter.
3. (c) Make reasonable inquiries where it is reasonably apparent that the client's information is incomplete or inaccurate, and get the complete or accurate information.
4. (d) Assess whether you have the expertise to give the advice sought, and decline to provide it if you do not.
5. (e) Conduct a reasonable investigation into the financial products that might meet the client's objectives and needs, and assess what that investigation turns up, if it would be reasonable to consider recommending a product.
6. (f) Base all judgements on the client's relevant circumstances, not on assumptions or on what suits you.
7. (g) Take any other step that, at the time, would reasonably be regarded as being in the best interests of the client given their relevant circumstances.

The safe harbour is not the only way to satisfy the duty. You can meet s961B(1) without relying on subsection (2). But in practice most advisers work to the safe harbour, because it turns a vague standard into a checklist you can evidence. We take each step in turn in the s961B safe harbour steps explained. And that word, evidence, is the whole game. A step you cannot show you took is, from a reviewer's point of view, a step you did not take.

How this differs from the broker best interests duty

A lot of practices sit across both advice and credit, so the difference is worth being clear about. Mortgage brokers have their own best interests duty, but it lives in a different law: section 158LA of the National Consumer Credit Protection Act, in force since 1 January 2021, with ASIC's guidance in RG 273. The wording sounds similar, but the mechanics are not the same.

The key gap is the safe harbour. The adviser duty gives you the s961B(2) checklist to prove compliance. The broker duty does not. There is no equivalent list of steps a broker can tick off to be deemed compliant. ASIC's guidance for brokers is deliberately principle-based, which means the standard is judged on the whole picture of what the broker did, not against a fixed set of steps. Different law, different structure, and if you write both kinds of file note, you cannot use the same mental template for each. We cover the credit side in how to write a compliant NCCP file note.

Why the file note is the evidence you met s961B

The Statement of Advice tells the client what you recommended. It does not show your reasoning at the moment you formed it. That is what the file note does. A contemporaneous file note, written while the conversation is fresh, is the record of what the client told you, what you inquired about, what options you looked at, what you ruled out and why, and what the client decided. It is the paper trail for the safe harbour steps.

When a complaint reaches AFCA or a review reaches your licensee, the assessor is trying to reconstruct your process from the file. A clean SOA with a thin file note behind it is a weak position, because the SOA shows the destination but not the journey. A slightly rough file note that clearly shows you identified the client's needs, made reasonable inquiries, investigated products and based your judgement on their circumstances is a strong one. The note is not busywork. It is the evidence.

What a good adviser file note captures for s961B

A file note that documents your best interests obligations should map, loosely, onto the safe harbour steps. The elements that carry the most weight:

• Who, when, how. Date, attendees, and channel. If the call was transcribed by your system, note that and note consent.
• The client's objectives, situation and needs, in their words. What they said they want, and what changed since the last review. This is step (a).
• The subject matter and scope of the advice. What you were and were not advising on. This is step (b), and it also protects you on scope.
• Any gaps you chased. Where the client's information looked incomplete and what you did to fill it. This is step (c).
• The options investigated and the trade-offs. What you considered, what you ruled out, and why. This is the evidence for step (e) and it is exactly the part thin notes skip.
• Why the recommendation fits this client. The reasoning that ties the advice to their circumstances. This is step (f) and it feeds appropriate advice under s961G.
• Conflicts and how you handled them. Anything relevant to the s961J priority rule.
• The client's questions, concerns and final decision. Including anything agreed verbally.
• Agreed next steps, who does what, by when.

The discipline that makes this defensible is consistency. A note that captures these elements every time, in the same shape, is far stronger than one that is detailed when you had a quiet afternoon and sparse when you had three meetings back to back. Consistency is also the thing that is hardest to keep up by hand, which is where a tool earns its place.

Best interests duty file note: a worked example

This is a made-up advice meeting, written up so each part of the note lines up with a step in s961B(2). The headings show which step each part evidences. Your own note does not need the section numbers, but it should cover the same ground.

A note like this is what lets you show, years later, that the advice was in the client's best interests. Our best interests duty file note checklist lists what to capture for each step.

Best interest duty statement example

People often search for this as a "best interest duty statement". The Act calls it the best interests duty, and s 961B does not ask for a document by that name. ASIC does not prescribe a form for one either. What advisers and licensees usually mean is a short written statement, kept on the file or included in the advice document, that says in plain words how the advice is in this client's best interests. Here is one for the same fictional client. It is an illustration only, and your licensee may set its own wording.

A statement like this is a summary. It only holds up if the file note and the documents behind it show the steps were taken, which is why the longer note above carries more weight in a review. For more scenarios, see best interests duty examples for advisers.

Where it usually goes wrong

The common failure points are not exotic. They are the same few things, over and over:

• No reasonable investigation on the file. The adviser landed on a product but the file does not show alternatives were considered, so step (e) cannot be proven.
• Scope quietly wider than the note. The client asked about one thing, the conversation drifted into another, and the note never fixed the boundary.
• Assumptions instead of inquiries. Gaps in the client's information were filled by assumption rather than a reasonable inquiry, breaking step (c).
• Best interests and appropriate advice failing together. The missing investigation that sinks s961B also sinks s961G, because you cannot reasonably conclude the advice is appropriate on facts you never gathered.
• A note written from memory a week later. By then the texture is gone, and a reconstructed note carries far less weight than a contemporaneous one.

How CallNote helps you keep the evidence

CallNote turns a call transcript into a structured file note in about two minutes. It does not record your calls and does not send a bot to your meeting. It receives the transcript your phone system or meeting platform already produced, then generates the note from it. You paste a transcript, upload a voice memo, forward one by email, or connect a phone system like Dialpad or Aircall so every call transcript becomes a draft note automatically.

You review the draft, then publish it: timestamped, SHA-256 sealed, with an append-only audit log so any later change is an addition rather than an edit. That fixed, contemporaneous record is exactly the kind of evidence that documents your s961B best-interests obligations if the file is ever reviewed. CallNote is hosted in AWS Sydney with AES-256 encryption and never uses your data to train AI models. It does not write your advice or make your judgement for you. It captures the conversation accurately and consistently, so your reasoning is on the file where it needs to be.

See a transcript become a draft note

Try the sample on the CallNote homepage to see an example transcript beside a structured draft note. No account needed. In the product, you review the draft before publishing it. CallNote receives transcripts; it does not record your calls or replace your professional judgement.

If that fits your process, start a 14-day trial and try a sample call in your own workspace. No card required.
