Ábaco (the Notarial Archive of Competition Terms and Conditions) began operating in 2003 as a general interest service provided by the General Council of the Notariat and managed by the Notarial Certification Agency (Ancert), allowing all web users to consult the content of the terms and conditions of competitions and prize draws filed with a notary, free of charge.

This is a service providing users with access to this information from any Internet terminal before subscribing to a particular commercial offer. It does not constitute commercial advertising by companies or the entities executing the act, nor the authorising notary.

During its first year in operation, 2200 sets of terms and conditions were filed with Ábaco, and it now contains more than 17,000, demonstrating the interest on the part of companies in publishing their competitions and prize draws registered before a notary.
