The legislation establishing FADN is Council Regulation 79/65/EEC of 15 June 1965. This legislation has since been modified and expanded; the basic act currently into force is Council Regulation (EC) No 1217/2009 of 30 November 2009 setting up a network for the collection of accountancy data on the incomes and business operation of agricultural holdings in the European Community.

Data are confidential
Incorporated into the founding legislation of FADN is a stipulation that all data relating to individual farms received by the Commission are to be treated with utmost confidentiality.
Consequently, data at the level of individual farms are normally not released outside the Directorate General for Agriculture of the Commission.
Only aggregated results for a group of farms and for farms within regions and Member States are published since, at this level of aggregation, information relating to individual farms cannot be discerned.
