In litigation and debt recovery work, the question is not simply whether a document can be sent. The more important question is whether the chosen method of service is the right one for the circumstances.
In some matters, service by post may be perfectly routine. In others, email may be convenient and entirely acceptable. But there are also many situations where relying on post or email creates unnecessary uncertainty. Where timing is tight, the recipient is evasive, the address position is unclear, or the evidential burden is likely to be scrutinised later, instructing a professional process server can be the more sensible and lower-risk option.
For solicitors, litigation departments, insolvency professionals, debt recovery teams, and commercial clients, this is not just a procedural detail. It is a practical case-management decision. The method used to serve documents can affect speed, certainty, cost efficiency, evidence, and ultimately the ability to move the matter forward with confidence.
