Most founders remember to file their incorporation paperwork. Far fewer remember the obligations that come *after* the certificate is issued. Two rules in particular are easy to overlook, and both can create real headaches during a routine check or a renewal cycle: how and where to display your registration certificate, and when you need a separate branch registration. A third duty — notifying the registry when your details change — ties them both together. This guide walks through each rule in plain English so you can stay compliant without guesswork.

The Display Requirement for Your Certificate

Once your registration is approved, the public certificate is more than a keepsake. In many jurisdictions, the law requires businesses to display the certificate (or a certified copy) at their registered office, principal place of business, or any location where it is "customary" to transact business with the public. The reasoning is straightforward: anyone dealing with your company should be able to confirm its legal existence and basic facts on the spot.

Common display practices include:

What happens if you forget? Inspectors can treat a missing certificate as a minor compliance breach. Depending on the jurisdiction, this can lead to a warning, an administrative fine, or a note on your compliance record that resurfaces at renewal or during a future audit. None of these are catastrophic on their own, but they are avoidable.

If your office moves, your certificate moves with you. This is where the notification duty (covered below) becomes essential — you may need an updated certificate reflecting the new registered address before you can display it correctly.

When a Branch Registration Is Required

A single registration covers your company as one legal entity, but it does not automatically cover every location or activity you operate. In most regimes, a separate branch registration is triggered when you establish a distinct physical premises or when you carry on a distinct line of activity under a name that needs to be made public. Below are the situations where founders most often get caught out.

Separate Premises

If you open a second office, a retail outlet, a factory, or even a dedicated warehouse that operates under the company's name and is open to customers or suppliers in a way that looks like a branch of the business, the registry typically expects a branch filing. "Separate premises" is judged by substance, not by the size of the sign on the door — even a small back-office used for regular client meetings can qualify if it functions as a recognizable point of contact.

Distinct Activity

Some jurisdictions also look at *what* you do at a location, not just *where* you do it. If you operate a separate business line under your company at a new site (for example, a logistics arm at a depot, or a training centre at a rented classroom), authorities may treat that as a branch requiring its own registration, even if it shares staff and branding with the main entity.

Why It Matters

Operating an unregistered branch can affect your ability to enforce contracts signed at that location, your tax treatment at that site, and your standing during inspections. It is one of the most common reasons a clean compliance record gets complicated during a scale-up phase.

The Duty to Notify When Details Change

Closely linked to both of the above is your obligation to update the registry when key details change. Typical triggers include:

Filing these updates is usually time-sensitive — often within a defined number of days after the change takes effect — and outdated information on the public record can invalidate your display certificate, complicate a branch filing, or undermine the validity of documents you sign on the company's behalf. Treat the notification duty as ongoing maintenance, not a one-off task.

A Simple Compliance Routine

A practical way to keep all three rules in good shape:

  1. Display the current certificate at every location that meets the test for visibility.
  2. Audit your sites once a quarter to confirm whether any new premises or activities now require a branch registration.
  3. File updates within the locally prescribed window whenever a director, address, or activity changes.

If you are unsure whether your specific situation triggers a branch filing or a particular notification deadline, treat it as a question worth answering before you assume you are in the clear.
