Service by Mail, and the Conditions on It
Mail is the method most people reach for and the one with the most conditions attached. Which class, to which address, with what proof, and whether the document in question may be posted at all are four separate questions.
The rule in short
Service by mail is permitted for many documents and excluded for some, and where it is permitted the rules usually specify the class of postage, the address that may be used, and the record that must be kept. Getting the method right is only part of it, because posting also changes when service is treated as effected and therefore when the recipient's time begins.
Posting a document is cheap, fast and permitted almost everywhere for something. The work is in establishing which documents, to which address, by which class, and what has to be kept afterwards.
When mail is permitted
For most documents after the first. Originating documents commonly require personal service, while later documents in the same matter can usually be posted.
Where the rule says so expressly. The permission is normally stated rather than implied, and its absence is meaningful.
Where a contract nominates it. Notice clauses frequently designate post as a permitted method and specify the address, per notice conditions inside a contract.
Where the recipient has agreed to it. Some systems permit the parties to agree postal service for documents that would otherwise need another method.
Where an order permits it. Alternative service orders very frequently specify post, sometimes combined with another method.
Not for originating process, usually. The document that starts a matter is the category most often excluded from postal service.
Not where personal service is required. Statutes and rules that specify personal service mean it, and posting is not a substitute.
Not to an address that is not permitted. A correct method to the wrong address fails as completely as an impermissible method.
The conditions usually attached
A prescribed class of postage. First class, certified, registered or recorded delivery, depending on the rule, and using a cheaper class can invalidate the service.
A permitted address. The address on the record, the last known address, or an address nominated in a contract, rather than any address the sender happens to have.
Correct addressing. The recipient's proper name and full address, because errors here are what most challenges are built on.
Prepayment of postage. Rules commonly require postage to be prepaid, and unpaid or underpaid items create obvious difficulties.
A complete enclosure. Every document that had to be served, since a missing exhibit makes the service defective whatever the envelope shows.
Dispatch by a stated time. Where a deadline applies, posting after the last collection may count as the following day, per the last day and what time it ends.
A record of posting. Certificates, receipts, tracking numbers or a franking record, depending on what the system accepts.
Sometimes a certificate of service. A separate signed statement recording what was sent, to whom, when and by which class.
| Question | Where the answer lives | Common error |
|---|---|---|
| May this document be posted? | The rule or statute | Assuming yes |
| Which class? | The rule or contract | Cheaper class used |
| Which address? | The record or clause | Any known address |
| When is it served? | Deemed date provision | Assuming arrival |
| What proves it? | Receipt and certificate | Receipt discarded |
When service takes effect
Usually on posting, not on arrival. Most systems treat service as effected when the item is put into the postal system rather than when it is delivered.
With a deemed date attached. Rules commonly specify a day, such as the second or third business day after posting, per deemed receipt, explained plainly.
Additional time for the recipient. Where the recipient's period runs from service, posting frequently adds days to it, per added time for service by mail.
Weekends and closures interact. A deemed date falling on a non-business day usually moves, and the rule specifying how should be read rather than assumed.
Actual earlier receipt rarely helps. A document that arrives before the deemed date does not usually accelerate the period.
Actual later receipt rarely helps either. Delay in the postal system is generally the recipient's risk once the sender complied with the rule.
Non-delivery may be different. Where an item comes back undelivered, the position changes and the sender cannot simply rely on the deemed date.
Different rules for different documents. The deemed date for one category may not be the deemed date for another in the same system.
Postal service is challenged months or years after the event, when the only surviving evidence is whatever was filed at the time. The receipt costs nothing to keep and is the document that decides the argument.
Proof and record-keeping
Keep the posting receipt. The document establishing when the item entered the postal system is the foundation of everything else.
Use a tracked service where it matters. The extra cost is trivial against the value of being able to show a delivery record.
Record the contents. A list of what was enclosed, made at the time, defeats the argument that something was missing.
Photograph or copy the envelope. The addressed envelope, before sealing, is useful evidence of correct addressing.
File the certificate of service promptly. Where one is required, filing it late creates its own problem, per proving that notice was given.
Note who posted it. The person who took the item to the post may need to confirm what they did.
Diarize the deemed date. Both for the sender's own purposes and because the recipient's period runs from it.
Keep everything together. Receipt, copy, certificate and diary entry in one place, because a challenge may arrive much later.
The usual failures
The wrong class was used. A rule requiring certified mail is not satisfied by ordinary post, however clearly the item arrived.
An outdated address was used. Which may still be valid if it is the address on the record, but is a problem if it is not.
The receipt was discarded. The commonest evidential failure, and one that only becomes visible months later.
The enclosure was incomplete. Missing schedules and exhibits, discovered when the recipient says so.
Posting was too late in the day. Items handed over after the final collection are frequently treated as posted the following day.
The deemed date was miscalculated. Which affects every subsequent deadline in the sequence.
Mail was posted to the wrong recipient. To the party where a representative should have received it, or the reverse, which is a familiar error in represented matters.
Nobody diarized anything. Service performed correctly and then forgotten produces exactly the same outcome as service never performed.
Service by mail is permitted for many documents and excluded for others, most commonly for the document that starts a matter.
Where it is permitted, the rules usually prescribe the class of postage, the address that may be used and the record that has to be kept, and each of those is a separate requirement.
Service normally takes effect on posting rather than on arrival, with a deemed date specified by the rule, and the recipient's period frequently gains additional days because post was used.
The evidential foundation is the posting receipt, supported by a record of the contents, a copy of the addressed envelope and a certificate of service where one is required.
The failures are consistent: the wrong class, an impermissible address, a discarded receipt, an incomplete enclosure and a deemed date that nobody calculated correctly.
Points to carry away
- Some documents may not be served by mail at all.
- The class of postage is frequently prescribed.
- The address used must be one the rules permit.
- Service usually takes effect on posting, not on arrival.
- Proof of posting is the record that matters.
Questions readers ask
Does service by mail take effect when the document is sent or when it arrives?
In most systems, on posting, with a deemed date specified by the rule for when the recipient is treated as having received it. That structure exists so that the sender is not exposed to postal delays outside their control, and so that everybody can calculate the following periods from a fixed point. Actual earlier or later receipt usually makes no difference, which is why the posting receipt matters more than any delivery confirmation.
What happens if the wrong class of postage is used?
It depends on how the requirement is framed. Where a rule specifies certified or registered mail, ordinary post generally does not satisfy it, and the service can be set aside even though the document plainly arrived. Some systems allow a substantial compliance argument where the recipient suffered no prejudice, but relying on that is a poor substitute for checking the rule, particularly since the cost difference between classes is negligible.
How long should posting receipts be kept?
Longer than seems necessary. Challenges to service surface months or years after the event, frequently when a party seeks to set aside something that followed from it, and by then the only evidence is whatever was preserved at the time. A receipt, a copy of the addressed envelope, a list of the enclosures and the certificate of service, kept together on the file, cost nothing and answer almost every question a challenge can raise.

More in Giving Notice
Notice That Is Correct and Useless
Formal compliance and actual communication are separate things. A notice that satisfies every requirement can still fail to reach anybody who understands it, because the address is stale, the format is impenetrable, the channel is unmonitored or the recipient cannot read the language. Systems accept a degree of this, and the practical response is to comply formally and then communicate separately.
Proving That Notice Was Given
Proof of service is built at the moment of service and consulted long afterwards. The elements are a contemporaneous record of what was sent, to whom, when, by what method and by whom, supported by receipts, delivery confirmations and a formal certificate where the rules require one. Reconstructed evidence is markedly weaker and frequently decisive against the party relying on it.
The Contents That Make a Notice Effective
Rules and contracts that require notice usually specify what the notice must contain, and a document missing a required element can be ineffective even where it plainly reached its recipient. The elements are commonly the identity of the parties, the nature of the matter, the action required, the period for responding and the consequence of not responding.
