If any details in your Commercial Registry entry change — such as your business address, ownership structure, trade name, or scope of activities — you are required to update the registry. Article 9 of Law No. 25 of 2005 allows any registered person to request a notation of changes or amendments to their registration details, subject to the prescribed conditions set by the Ministry.
The application for deletion or amendment must generally be submitted within 30 days of the change occurring, as indicated by Article 12 which sets this timeframe for deletion requests — a standard that reflects the law's broader expectation of prompt notification. If you fail to update your details, the Ministry may take administrative action, and continuing to trade with inaccurate registered information can expose you to liability.
Practically speaking, gather supporting documentation for the change (for example, a new lease agreement for an address change, or updated company incorporation documents for ownership changes) before visiting the relevant department. Fees for notations are set under Article 14 by Ministerial resolution. Keeping your registry entry accurate also protects you commercially, since third parties and government authorities rely on the registry as the official record of your business details.
