Keep the address-change confirmation when reviewing a late DPN

Sending an update request may not explain the register
You receive a director penalty notice through an old address and remember asking someone to update your details. Find the actual filing evidence and seek urgent legal advice. A request to the accountant, a completed draft form and confirmation of a processed change are different records. The adviser needs the real sequence rather than an assumption that the address changed when the request was sent.
Collect the relevant confirmations
Imagine a director emailing an address change to the company administrator during an office move. Preserve that email, any submitted form and the acknowledgement or confirmation available through authorised channels. Keep dates and the particular details changed clear. Updating a company office address is not necessarily the same task as updating every relevant personal director detail.
Have the notice rules assessed precisely
Section269-50 of Schedule1 to the Taxation Administration Act provides for notices to be left at or posted to certain addresses appearing from ASIC information. Ask the lawyer to assess the exact statutory requirements against the evidence. Do not assume that a later update invalidates an earlier notice or that discovering it late creates a new response period.

Keep old and new records together
In the director's example, the confirmation may show a different date from the email requesting the change. Provide both without editing the history. Preserve the notice and envelope as well. Do not rely on publicly available extracts to contain every personal address detail; obtain appropriate authorised records or ask the adviser how the relevant information should be confirmed.
Correct current details through proper channels
Ask the responsible person to check what still needs updating and retain confirmation of completed changes. Treat that as a current administrative task alongside urgent advice on the existing notice. Do not wait for the register work to finish before sending the lawyer the notice, and do not describe an intended correction as already processed in communications with advisers.
Record the advised action separately
Have the lawyer confirm what must happen about the DPN and when. Keep that instruction distinct from the address-maintenance task. A reliable filing history can help assess the delivery question, while accurate current contact details reduce the chance of another missed communication. Neither should be treated as a substitute for addressing the notice already issued.
