NDIS Plan Management for Parents and Nominees: Who Does What?

When you help someone with an NDIS plan, the admin can quietly become your responsibility too. A plan manager can take care of the financial processing, but they don't replace the participant, nominee, family, or support team. Knowing who does what makes the arrangement easier for everyone.

What a plan manager does

An NDIS plan manager handles the financial administration attached to a participant's plan. Depending on the service, that usually includes receiving provider invoices, checking the basic claim information, submitting claims to the NDIS, paying providers, and giving you statements or updates about spending.

They can also explain why an invoice is missing information or why a claim needs to be corrected. That can be a big relief when you're already coordinating appointments, transport, school, work, and family life.

A plan manager doesn't decide which supports the participant should receive. They don't approve a new therapy, choose a support worker, or guarantee that every invoice can be claimed. Those decisions still need to be made by the participant and their decision-maker, with advice from the relevant professionals where needed.

What the participant still controls

The participant remains at the centre of the plan. They generally choose their providers, agree to services, check that supports are useful, and decide who should receive information about their plan.

If the participant has capacity to make a decision, a family member can't automatically make it for them just because they help with paperwork. The participant's preferences and privacy still matter. A good support arrangement makes room for the participant to be involved in a way that works for them.

This can look different for every family. Someone might review invoices independently, while another participant might prefer a parent, partner, advocate, or nominee to handle most communication.

What a nominee can do

A nominee's authority depends on the type of nominee arrangement and what the NDIA has recorded. Some nominees support decisions. Others may be appointed to make decisions on a participant's behalf. Don't assume that being a parent, carer, or emergency contact gives you every authority automatically.

If you're unsure, check the participant's NDIS records or ask the NDIA what the nominee arrangement allows. Your plan manager may also need evidence of who is authorised to receive information or give instructions about an invoice.

This is one of those details that trips people up: being able to talk about a provider's invoice isn't necessarily the same as being able to change the participant's plan or make a major support decision.

What information should be shared?

At onboarding, give the plan manager the information they need to process claims and communicate safely. This may include:

• the participant's preferred name and contact details
• the nominee or authorised representative's details
• the plan start and end dates
• provider contact information
• communication preferences and accessibility needs
• any relevant consent or authority documents
• the best way to flag an urgent problem

Only share information that is needed. Personal information should be sent through the plan manager's approved portal or email process, not a casual social media message.

How the three-way communication works

A simple arrangement usually has three separate conversations. The participant or nominee agrees with the provider about the support. The provider sends an accurate invoice. The plan manager processes the claim and reports the financial result.

If something doesn't match, the plan manager may contact the provider, participant, or nominee for clarification. They should explain what is needed rather than quietly making assumptions. Likewise, tell them when a provider has stopped, changed, or paused a service so old invoices don't keep arriving unexpectedly.

A plan manager can process an invoice, but they can't confirm whether a support was actually delivered. The person who knows that is usually the participant, nominee, or provider.

If the participant's circumstances change

Tell the plan manager when the participant changes providers, moves, starts a new support, or has a change in who is authorised to communicate. Also tell the NDIA about changes that affect the participant's plan or circumstances when required. A plan manager can't update the plan simply because they heard about a change in an email.

Plan management is fully NDIS-funded at no cost to you when it is included in the plan. The NDIS adds plan management funding on top of the participant's support budgets, so it isn't taken from Core or Capacity Building funding.

For background, read what NDIS plan management is, then see our NDIS nominee guide. If you're choosing a provider, questions to ask an NDIS plan manager can help.

Make the arrangement easier

At the beginning, write down who does each job and who should be copied into messages. Ask the plan manager how they handle consent, rejected claims, statements, and urgent questions. A few clear boundaries early can prevent a lot of confusion later.

Families and nominees do a huge amount of practical work. You shouldn't have to guess which part belongs to you. If a plan manager's process isn't clear, ask them to explain it in plain English.
