When is the deadline for deemed service of the statement of claim by registered letter?
Registry and served defendant uses 10 days to establish the conditional deemed service date, measured against posting of the registered letter with acknowledgement of receipt or equivalent. Later actual arrival, failure to arrive or an unreturned acknowledgement defeats the simple tenth-day presumption. This is not a filing deadline. The ordinary source period remains a conditional fixed boundary, not a variable period merely because this page withholds a calculation. This guide supplies no calculated final date.
