What is the siège social?

✅ In brief


The siège social is the company’s official address. It is used in particular for mail, formalities and official documents.


🧭 What you need to know


  • The siège social appears in the statuts and on official documents.
  • It can be different from the actual place of operation depending on the case.
  • It determines certain administrative connections.
  • Changing the siège social after creation requires formalities.


🛠️ How Leegal supports you


  • Leegal helps you understand the wording shown during the creation process and prepare a clearer file.
  • The flow can organize information, documents and points to watch, but it does not replace a personalized review.
  • If your situation is specific, it is still preferable to ask a chartered accountant, a lawyer or another qualified professional for advice.


🔎 Points to check


  • The exact address and supporting documents.
  • Whether this address can be used.
  • Where mail will be received.
  • The consequences of a future change.


⚖️ Limits to know


  • Leegal is not a law firm or an accounting firm.
  • Leegal explains the options and helps prepare formalities, but does not choose for you.
  • Tax, social security or personal asset consequences can depend on your actual situation.


📌 Key takeaway


The siège social is the official address of the business; you must be able to justify it.
