Core Compliance Concept

Supported Decision-Making vs Substitute Decision-Making

The NDIS Commission requires providers to adhere to the presumption of capacity before seeking third-party signatures.

Supported Decision-Making (Default)

The participant makes their own choices with the support they need. Providers adapt communications (e.g. easy-read summaries, visual schedules, mobile-friendly 1-tap signing) so the participant can review and sign directly.

  • Presumed legal capacity under Commonwealth law
  • Family and advocates provide advice without replacing consent
  • Audit gold standard for Core Module Indicator 2.1
Primary Standard for NDIS Providers

Substitute Decision-Making (Formal Delegation)

A legally appointed representative signs on the participant behalf. This occurs only when formal legal mechanisms exist (NDIA Plan Nominee or state tribunal guardianship orders).

  • Requires written statutory delegation on file
  • Representative must act in participant best interest
  • Fair Enough records representative capacity on certificate
Mandatory Formal Documentation Required

Frequently Asked Questions

NDIS Guardian & Nominee Signing FAQ

Key answers on legal capacity, nominee powers, and avoiding audit non-conformances.

Under the NDIS Act 2013 and general Australian contract law, family members do not have automatic legal authority to sign binding contracts on behalf of an adult participant simply by virtue of being related. Unless they hold a formal NDIA Plan Nominee appointment, a State Tribunal Guardianship order, or an Enduring Power of Attorney with contractual powers, the participant should sign directly under a supported decision-making model.
