Any significant change to a Guatemalan company’s corporate structure must be formalized through a modificacion de escritura social (corporate charter amendment) and registered at the Registro Mercantil. This includes changes to the company name, registered address, business purpose, capital structure, legal representative, and partner or shareholder composition. Failing to register these changes means they have no legal effect against third parties, which can create serious problems in banking, contracts, and litigation.
The process always begins with a notary. A Guatemalan notario drafts an escritura publica de modificacion that describes the specific changes being made to the original corporate charter. This document must reference the original escritura and registration number, describe the changes in detail, and be signed by the authorized parties (legal representative or shareholders as required by the company’s bylaws and the Codigo de Comercio).
Corporate amendments are a normal part of business life. Companies change names when rebranding, increase capital when growing, change their legal representative when leadership transitions, and modify their business purpose when entering new markets. The Registro Mercantil provides a standardized process for recording all of these changes in the public commercial registry.
Quick summary: Corporate amendments require a notarized public deed, registration at the Registro Mercantil (Q100 base fee), and take 1-3 weeks to process. All changes to your corporate charter must be registered to have legal effect.

Tips & Common Mistakes
- Verify the requirements for your specific modification. Capital increases, for example, have additional documentation requirements and proportional fees that name changes do not.
- Update SAT records after the modification. Any change in the Registro Mercantil (especially name, address, or legal representative) must also be updated in the SAT’s RTU (Registro Tributario Unificado).
- Keep your original escritura accessible. The modification deed must reference it precisely, including the notary protocol number, date, and registration number.
- Some modifications require publication. Capital reductions and mergers, for example, must be published in the Diario de Centro America before taking effect.
