The underlying signing power comes from the valid corporate appointment and registered representation structure; the circular evidences that authority rather than creating unlimited powers."},{"Soru":"What is the difference between an \u0130mza Sirk\u00fcleri and an \u0130mza Beyannamesi?","Cevap":"An \u0130mza Beyannamesi is the specimen-signature declaration used within the Trade Registry framework for authorised signatories, while an \u0130mza Sirk\u00fcleri is practical notarised evidence of the company's registered representation structure and is often requested by banks, notaries, counterparties or institutions."},{"Soru":"Is a signature circular legally required for a Turkish company to exist or operate at all?","Cevap":"No blanket statement is safe. The company legally exists through Trade Registry registration and its representatives derive authority from the corporate and registry framework. A signature circular is nevertheless operationally important because many banks, notaries and counterparties request current representation evidence."},{"Soru":"Can a foreign manager or director have a Turkish signature circular?","Cevap":"Generally yes, where the foreign person validly holds the relevant representation authority. The notary will require suitable identity and current corporate-authority evidence, and sworn-interpreter involvement can be required where the person does not sufficiently understand Turkish for the notarial act."},{"Soru":"Does every signature circular automatically expire after 2, 5 or 10 years?","Cevap":"No. There is no universal 2-, 5- or 10-year expiry rule for every circular. The relevant questions are whether the underlying representation authority is still valid and whether the receiving institution requires a recently issued or updated document."},{"Soru":"Does every company address change require a new signature circular?","Cevap":"Not automatically. A new or updated circular is clearly relevant when the manager, director, representation method or registered authority changes.
