Corporate documents, also known as legal documents, are a set of specific documents that write down all the necessary facts about the company. These documents are called the face of the company as they are the source of official information about the company. Whenever a company is formed or changed, documents containing facts about the company or the facts about the changes in company law must be filed with the business register. The registry amends the information in the commercial register and attaches the submitted documents to the company's file so that any person is entitled to receive the official facts about the company.

There are different types of corporate documents, each containing different information. The most important documents are the constituent documents, such as the memorandum of association and the articles of incorporation.
