Our History
A legacy of trust since 1956
Sanz-Lamas is the result of a family tradition dedicated to excellence. Since our founding, we have grown alongside Castellón, becoming a leader in legal certainty and administrative reliability for businesses and individuals.
Our experience allows us to manage with a confidence that only comes from decades of experience: we apply regulatory standards with the confidence of those who have a thorough understanding of the government.
Current Situation
Infrastructure and New Technologies
We have state-of-the-art technical infrastructure that allows us to operate 100% online. Thanks to our integration with government agencies, we can process transactions with the DGT, AEAT, and Social Security immediately.
This technological approach does not replace personal service; it enhances it. We have the necessary resources to ensure that the process is efficient, transparent, and, above all, convenient for you.
