1. What is a Legal Address and Why is It Required?

Under Turkish Commercial Code, every company must declare a legal address (kanuni adres) at the time of incorporation. Istanbul Law Firm explains that this address becomes the company’s official domicile for court service, tax inspections, and regulatory notices. Turkish Lawyers advise that the legal address must be located within Turkey and must be supported by a valid lease contract, title deed, or shared service agreement. Turkish Law Firm helps clients avoid registration delays by pre-validating address documents, obtaining municipality approvals if required, and coordinating with landlords. English speaking lawyer in Turkey professionals guide clients on choosing between physical office, co-working space, or virtual legal address structures.

Istanbul Law Firm ensures that the declared address is consistent across all filings and meets location-specific documentation requirements.
