The Best Interests Duty is a statutory obligation requiring mortgage brokers providing home-loan credit assistance to act in the client’s best interests, and to give the client’s interests priority where a conflict arises with the broker’s own. It sits inside the National Credit Code framework alongside responsible-lending obligations rather than replacing them.
Because the law states principles rather than a checklist, plenty of myths surround it. This guide explains what the duty actually requires, how it differs from what brokers assume, and what good compliance evidence looks like.

What Is Best Interests Duty?
Introduced in 2020 after the banking royal commission and operating for mortgage brokers since 2021, the duty has two moving parts: act in the consumer’s best interests when providing covered credit assistance, and prioritise the consumer’s interests when conflicts arise, such as commission differences between lenders.
Understanding Best Interests Duty
Components of BID Compliance
There is no mandated three-step formula and no requirement to find one objectively best product in every case. The duty asks whether you took steps that were reasonable in the circumstances: understanding the client’s requirements and objectives, making reasonable enquiries into their situation, and researching options within your lender panel before recommending. What counts as reasonable scales with the file’s complexity.
Legislative Background and Implementation
The legislation leaves best interests undefined on purpose; regulatory guidance from ASIC fills in the detail, including factors regulators consider when assessing compliance. That flexibility cuts both ways: no rigid script to follow, but also no safe harbour from simply completing a form.
Compliance and Documentation
Your practical protection is a documented trail: what you asked, what the client said mattered to them, which loans you considered and why the recommendation won. Records do not automatically shield you from a dispute, but an undocumented file is far harder to defend when a complaint or licensee review arrives. Good notes also strengthen client relationships, because the reasoning stays visible across years-long lending cycles.
Types Of Assessments Under Best Interests Duty
Understanding Client Needs
Sometimes clients want something at odds with what you would choose, such as chasing the lowest headline interest rates while ignoring features they will need later. The duty does not let you overrule them; it expects you to explore the trade-off, explain the consequences plainly and record that conversation.

How BID Fits With Other Financial Regulations
Two misconceptions die here. First, responsible lending is more than an affordability box-tick, and BID does not convert broking into a lowest-rate mandate: the duty applies within your panel and weighs suitability overall, including fees, features and the client’s stated priorities. Second, neither obligation replaces the other; a recommendation can pass serviceability and still fail the client’s interests if you ignored obviously better-fitting panel options.
Best Interests Duty And Loan Products
In practice the duty shows up in how widely you search before recommending. Comparing rates, repayment terms, offsets, fees and exit costs across your panel, then recording the shortlist you rejected, demonstrates the research the duty expects. A smaller panel makes this easier, not harder, because the comparison set is defined.
Broker’s Ethical Considerations
Commission differences between lenders are exactly why the conflict-priority limb exists. Disclose commissions upfront, and if two loans serve the client equally well, the conflict rule tells you which way to fall. Documenting that reasoning protects both client and broker.
Best Interests Duty In Practice: A Case Study
Consider a hypothetical first-home buyer who asks for the cheapest rate available. The broker enquires further and learns the client expects to renovate within two years, making a redraw facility relevant to the conversation.
A compliant process does not decide in advance which product wins. It compares panel options against the client’s stated objectives, walks the client through the trade-offs between rate and features, lets the client choose with full information, and records why each option was considered or set aside. This case study pattern, enquiry through to documented comparison, is what reviewers look for regardless of which loan the client picks.
Challenges And Opportunities For Brokers
Navigating BID Compliance
The real cost of the duty is time: broader enquiries, wider comparisons and fuller notes on every file. Smaller brokerages feel this most. The common mistake is treating compliance as paperwork bolted on after the decision instead of the decision process itself; once the reasoning IS the record, the extra burden mostly disappears.
Leveraging Technology
Tools reduce that burden legitimately: a Customer relationship management system keeps enquiry notes attached to files, comparison software documents the options you reviewed, and templated record prompts stop details going missing between meeting and submission.
This week, pick one recent file and test it: could a stranger reconstruct what the client wanted, which options you compared and why the recommendation fit? Whatever gap you find is exactly what to fix before the next file, and closing it is the surest way to build trust with both clients and reviewers.
