The Australian Financial Complaints Authority has issued guidance that formalises the evidentiary standard insurers must meet when relying on retrospective underwriting decisions following alleged non-disclosure or misrepresentation - and the practical consequence is that underwriting documentation quality is now a central determinant of dispute outcomes rather than a peripheral compliance consideration.
AFCA received 100,745 complaints in 2024-25, the second consecutive year above 100,000 cases despite a 4% year-on-year decline. The two External Dispute Resolution response guides cover sections 29(6) and 29(7) of the Insurance Contracts Act 1984, applying to both superannuation and retail life insurance disputes. While positioned as procedural guidance, the documents define how AFCA will assess insurer reliance on retrospective underwriting reconstruction under ICA section 29 - particularly where cover has been varied after claim lodgement.
Section 29(6) disputes turn on whether insurers were entitled to vary cover based on what underwriting outcome would have applied if full disclosure had been made at application. Section 29(7) introduces a second threshold, requiring insurers to demonstrate that any variation is consistent with the position of other reasonable and prudent insurers.
In practice, ICA 29 disputes are increasingly assessed through a reconstruction framework. Insurers must evidence what information was available at the time of application, how that information was assessed under contemporaneous underwriting standards, what decision would have been made under full disclosure, and whether that outcome aligns with broader market practice. The guidance consolidates expectations that these positions must be supported by structured, contemporaneous records rather than retrospective justification - a distinction that effectively closes the option of reconstructing a defensible underwriting position after a claim has been lodged.
A central feature of the guidance is the level of documentation required in EDR responses. AFCA sets out expectations for structured evidence packs covering complaint summaries and policy schedules, application and underwriting records, correspondence logs between insurer, trustee and complainant, premium histories and variation calculations, and decision letters and procedural communications. For superannuation cases, executed trust deeds and amendments are also required. This effectively establishes a minimum viable EDR file architecture for ICA 29 disputes - a standard that underwriting, claims and dispute resolution functions will need to build toward jointly rather than assembling at the point a complaint is received.
For insurance held within superannuation, the guidance places trustees closer to underwriting governance than previous dispute frameworks. Trustees must now evidence independent review of insurer reliance on section 29, assessment of application disclosure clarity, consideration of procedural fairness in retrospective variation decisions, and documentation of their own decision-making process. This reflects an ongoing shift in expectations around trustee oversight of group insurance arrangements, particularly where insurers apply retrospective underwriting adjustments after claim lodgement - moving trustees from passive administrators of insurer decisions to active participants in the governance of those decisions.
The most operationally significant element of the guidance is the treatment of comparative underwriting under section 29(7). AFCA requires insurers to demonstrate that retrospective underwriting decisions are not inconsistent with those of other reasonable and prudent insurers, with supporting material potentially including external underwriting opinions, reinsurer input or comparable policy approaches. Critically, firms must also explain how that material applies to the specific facts of the complaint rather than simply citing it as general market evidence. This substantially increases the evidentiary burden on insurers where underwriting practices vary across product lines or risk segments, and where market comparators are not readily standardised - conditions that apply across much of the life and group insurance market.
The guidance has different practical implications depending on where a firm sits. Underwriting governance teams must ensure historical underwriting decisions can be reconstructed with sufficient granularity, including rationale for acceptance terms, exclusions and loadings - documentation that is often not captured at the depth the reconstruction framework now requires. Claims and dispute resolution teams will increasingly need integrated evidence across underwriting, claims and trustee records rather than siloed functional inputs assembled under time pressure when a complaint arrives. For superannuation trustees specifically, independent review of insurer decisions is now a documented obligation rather than an implied expectation.
The ICA 29 guidance sits within a broader AFCA trend toward structured evidentiary expectations across insurance disputes. Across life and general insurance complaints, AFCA has increasingly emphasised completeness of underwriting and claims records, clear articulation of decision-making rationale, and structured justification of fairness in outcomes - a convergence toward standardised dispute evidence frameworks that the ICA 29 guides now make explicit for retrospective underwriting decisions.
Retrospective underwriting decisions must now be defensible through contemporaneous evidence capable of withstanding external comparative scrutiny. As ICA 29 disputes continue across both superannuation and retail life insurance portfolios, the firms best positioned are those that treat underwriting documentation as a dispute-readiness asset from the point of policy inception rather than a record assembled when a claim is challenged.
