From 1 January 2026, significant changes to the High Court Rules came into force under the High Court (Improved Access to Civil Justice) Amendment Rules 2025.

These reforms introduced a front‑loaded disclosure regime and reinforced strict document preservation duties. For parties involved in High Court litigation, understanding and complying with these obligations is essential—and failing to do so can have serious consequences.

Norling Law assists clients in navigating these new requirements efficiently and strategically.

A Shift from Traditional Discovery Obligations to Early Disclosure

The traditional discovery process has been replaced by a streamlined initial disclosure regime. Parties must now provide a bundle of key documents—including adverse documents—at the same time as filing their first substantive pleading.

This means you must produce:

  • Documents referred to in your statement of claim or defence
  • Documents used to prepare those pleadings
  • Documents you intend to rely on at trial
  • Documents that adversely affect your position

The initial disclosure must be verified by affidavit.

This is a major shift: instead of discovering documents through the proceeding, disclosure happens at the very start of the case.

Further Disclosure Is Limited and Controlled

Additional disclosure beyond the initial stage is no longer automatic. Further disclosure of other documents will only occur if:

  • The opposing parties agree to it, or
  • A Judge orders it under the new rule 8.4A.

Importantly, the Court may limit or refuse further disclosure in the court proceeding, unless it will best achieve the overriding objective of proportionality.

For clients, this means the early stages of litigation matter more than ever. Preparing the right documents from the outset is critical.

Document Preservation Duties: What You Must Do Now

Even before proceedings begin, parties have a duty to preserve all relevant documents. With the new front‑loaded disclosure framework, early preservation becomes even more important.

Documents that must be preserved include:

  • Emails and text messages
  • Digital files and shared workspace content
  • Contracts, notes, and drafts
  • Internal communications about the dispute
  • Any material that may be adverse to your position

Destroying, altering, or failing to preserve relevant documents can result in:

  • Adverse inferences by the Court
  • Costs sanctions
  • Significant damage to the credibility of your case

Because initial disclosure demands immediate production of documents, failing to preserve material early may put you at serious risk.

What The New Disclosure Legislation Means for Your Litigation Strategy

Under the new rules, litigation becomes more demanding at the outset. You must expect:

  • More work early, not later
  • Higher initial legal costs due to intensive preparation requirements
  • Less tolerance for incomplete or late disclosure
  • Greater expectations that you already understand your case’s strengths and weaknesses before filing

Destroying, altering, or failing to preserve relevant documents can result in:

  • Adverse inferences by the Court
  • Costs sanctions
  • Significant damage to the credibility of your case

The intention behind the reforms is to reduce unnecessary disputes, but for parties unfamiliar with the process, the disclosure obligations can be difficult to navigate without skilled legal support.
