One of the competencies of the UIFAND is the one corresponding to the development of Law 14/2017 and its applicable regulation, which can be done through the publication of Technical Communiqués. Technical Communiqués are legal instruments that set out recommendations and guidelines that the Unit considers appropriate and that must be complied with by the reporting entities to which they are referred to. These Technical Communiqués can be issued exclusively by the UIFAND, but also in conjunction with other public institutions.

It should be taken into account that, up until 2019, some of the Technical Communiqués had to be accessed through the restricted area by the reporting entity to which it was addressed (such as, for example, the Technical Communiqués concerning audit requirements).

It should be noted that non-compliance with the Technical Communiqués issued by UIFAND is considered a serious offence, pursuant to the provisions of Article 72 paragraph 14 of Law 14/2017, of 22 June, on the prevention and fight against money laundering and the financing of terrorism.
