TEGoVA Spain

ATASA and AEVIU have established "TEGoVA Spain" which is seeking a convergence of Spanish valuation standards and practice with the rest of the EU and to enable employees of valuation companies to become Recognised European Valuers.



At the end of 2014, the Spanish TEGOVA member associations AEVIU and ATASA formed TEGOVA SPAIN. Its main goal is to work together to pursue and defend common interests.
