When is a claim form deemed served?

The claim form is the document limitation periods live or die on, so the rules give it a deemed service regime of unusual simplicity: one uniform answer, the second business day after the step, with no method by method table to consult.

The relevant step

CPR 7.5 defines what must be done, and by when, for each method: placing the claim form in the post or with the DX provider, delivering it to or leaving it at the relevant place, personal service, or completing the electronic transmission. That step must be completed before midnight on the calendar day four months after the date of issue (six months where the claim form is to be served out of the jurisdiction). Two business days later, CPR 6.14 deems service to have occurred. Note the sequence carefully: validity is tested against the step, not the deemed date, so a claim form posted on the last day of the four months is in time even though deemed service lands afterwards.

What flows from the deemed date

The response timetable. Particulars of claim, if not served with the claim form, must follow within 14 days of service of the claim form and within its validity period. The defendant then has 14 days from service of the particulars to file an acknowledgment of service or a defence, extended to 28 days for the defence where an acknowledgment is filed. Every one of those periods is computed from deemed dates, not doormats.

The high stakes edge

Where limitation has been protected by issuing and the four months are running down, service becomes the whole case: a claim form that expires unserved usually cannot be revived, and extensions are granted sparingly. This is the scenario in which professional same day personal service earns its fee, completing the relevant step against the clock with evidence beyond argument.
