We provide legal counsel on the application of European regulations concerning the coordination of social security systems, particularly in the context of labor mobility within the European Union. We assist employers and individuals in determining the applicable legislation, obtaining the required documentation (such as the A1 certificate), and managing social security contribution obligations for activities performed across multiple Member States. Additionally, we offer support in dealings with competent authorities, clarifying the legal status of posted or mobile workers, and resolving disputes or complex legal situations arising from cross-border professional activities.
