Service 

Service is the formal delivery of a court document to a party (or, in some cases, to a non-party) in a manner recognised by the rules of court. It is easy to treat as a mechanical administrative step, but service performs a foundational function in civil litigation: it is the mechanism by which a court's power over a person is actually engaged, and by which a party's right to know what is alleged against them, and to answer it, is made real rather than theoretical.

Why service matters

A court does not generally have authority to make orders affecting a person's rights until that person has been brought within the proceeding, and the ordinary way that happens is by service of the originating process. Service is therefore closely tied to procedural fairness (sometimes called natural justice): a person cannot fairly be bound by a judgment in a case they were never told about. Because so much turns on it, the rules of every Australian court prescribe, in some detail, who may be served, how, when, and what must be done to prove that service occurred.

Personal service

Personal service involves physically handing the document to the individual to be served, or otherwise ensuring it is delivered directly to them in a manner the rules recognise (for a corporation, this typically means delivery to a person holding a relevant office, or to a registered address, in the manner the rules or corporations legislation permit). Personal service is generally required, or at least strongly preferred, for originating process — the document that first brings a person into a proceeding — because it gives the clearest evidence that the party actually received notice.

Serving a document is usually followed by filing proof of service, commonly an affidavit of service, so that the court and the other parties can be satisfied the requirement has been met.

Substituted service

Where personal service cannot practically be achieved — because a party is evading service, cannot be located, or is overseas in circumstances that make personal delivery impracticable — a party may apply to the court for an order permitting substituted service: service by some other method reasonably likely to bring the document to the other party's attention, such as service on a solicitor known to act for them, service at a last known address, or, increasingly, service by email or other electronic means. Substituted service is not a lesser or optional alternative available whenever it is convenient; it typically requires the court's leave, and the applicant must generally show both that ordinary service has been attempted or is impracticable, and that the proposed method is genuinely likely to bring the document to the other side's notice.

Why defective service matters

If service is defective — the wrong method was used, the wrong person was served, or service did not occur at all — consequences can be serious. A defendant who was never validly served may later apply to have a judgment obtained against them set aside, on the basis that the court's process never properly engaged them and they had no real opportunity to defend the claim. Conversely, a plaintiff whose claim is at risk of becoming time-barred needs to ensure that valid service occurs within any time limit the rules impose for serving originating process after filing, or the proceeding itself may be at risk. Because defective service can unwind an otherwise favourable outcome, careful practitioners treat proof of proper service as a foundational step, not an afterthought.

Service across borders

Where a party to be served is outside the Australian jurisdiction in which the proceeding is filed — whether interstate or overseas — additional rules govern whether and how service can occur, often requiring the court's permission and engaging separate considerations about whether the court is an appropriate forum for the dispute at all. Those cross-border service rules again differ between courts and are a further illustration of why service cannot be treated as a single uniform national procedure.

Applying this in a problem question

1. Identify what is being served and to whom, and confirm which court's rules govern the mode of service required.
2. Check whether personal service was required for the document in question, and whether it was achieved.
3. If personal service was not used, ask whether substituted service was sought and properly ordered, and whether the method chosen was genuinely likely to bring the document to notice.
4. Consider whether any time limit for service after filing was met.
5. If service is defective, identify the consequence you are being asked about — a set-aside application, a limitation problem, or a challenge to the court's jurisdiction over the party.
