Headquarters and Branches of the Commercial Enterprise

1) Why is the distinction between "Head Office" and "Branch" so important?

In practice, the distinction between a "head office address" and a "branch address" is often seen as merely an operational preference. However, the head office-branch distinction directly affects registration and publication in the trade registry , how the trade name is used , MERSIS numbering , representation authority , notification and contractual relationships , and even the court where lawsuits will be filed

Whether a business is considered a "branch" or not can sometimes affect the outcome of a case in banks' loan processes, in disputes over signing authority in contracts, and in determining the competent court for resolving disputes.

2) What does the term "Headquarters" of a commercial enterprise mean?

The headquarters is the main organizational point where the management and administration of a commercial enterprise take place, and where the enterprise's "main identity" to the outside world is formed. In terms of commercial registry, the headquarters is the place where the merchant registers their commercial enterprise in the commercial registry of the location where the business headquarters are located

The concept of a center manifests itself in practice under three headings:

• Registered office in the commercial registry: The address of the office as it appears in official registry records.

• De facto administrative center: The place where decisions are made and administration is actually carried out.

• Business headquarters: The location where the main operational organization of a business is established.

In most cases, these three overlap; however, divergences can occur, particularly in rapidly growing structures, holding companies/groups of companies, or during relocation processes. These divergences become a point of contention, especially in matters of notification and jurisdictional objections.

3) What is a "Branch"? (Definition and Distinguishing Criteria)

Since the definition of a branch can be controversial in practice, the definition in the legislation is decisive. Article 118 of the Commercial Registry Regulationa branch as a place or sales outlet attached to a commercial enterprise where industrial or commercial activity is carried out independently, ; furthermore, whether or not independent capital or accounting is maintained is not considered a determining factor on its own.

When we translate this definition to "application filter," the typical indicators for the branch are as follows:

• Affiliation: The branch is subordinate to the head office; it is not a separate legal entity.

• Continuity: Unlike temporary stands/event points, it operates continuously and regularly.

• External activity: Establishes direct legal relationships with third parties (sales, services, contracts, collections, etc.).

• Organization: There is staff, operational flow, and activity schedule.

• Representation/Ability to conduct transactions: The ability to conduct transactions on behalf of a branch (within the limits of its authority) strengthens the branch.

A place that only operates as a "warehouse," "shipping point," or "liaison office" and does not conduct independent transactions with the outside world may not always be considered a branch. However, if it actually begins to enter into contracts with third parties, it becomes a branch, "regardless of its name.".

4) Registration and Publication Regime of the Head Office and Branches

(a) Headquarters registration: The merchant shall register and announce his commercial enterprise and trade name in the trade registry of the place where the business headquarters are located within a specified period from the opening of the business

(b) Branch registration (businesses headquartered in Turkey): Branches of commercial enterprises headquartered in Turkey are also registered and announced in the trade registry of the place where they are located . Moreover, the rules regarding title and signature samples also apply to branches

(c) Linking of records: As a rule, the records in the registry to which the central office is affiliated are expected to be reflected/registered in the branch's registry; in practice, this is a mechanism where fundamental changes in the central office are also recorded in the branch's registry using the "related record" logic.

(d) Branches of foreign-based businesses in Turkey: Branches of businesses headquartered outside Turkey are also registered in Turkey according to certain principles; in addition, fully authorized commercial representative residing in Turkey must be appointed.

This framework has a practical consequence: the "we opened a branch, we put up a sign" approach is risky in terms of transparency to the commercial registry and third parties. If the branch is actually operating but does not appear in the registry, it will produce unfavorable results in disputes regarding signatures, representation, contracts, and liability.

5) How to Use a Branch Trade Name?

The branch's trade name is not a "separate" name from the head office. The law requires the branch to use the trade name of its head office and to add a label indicating that it is a branch

The Commercial Registry Regulation complements this logic: the branch's name consists of the head office's name plus an addition indicating that it is a branch; in the case of a branch of a foreign-based business, both the location of the head office and the branch, as well as the word "branch," must be clearly indicated.

6) MERSIS and Branch Number: Why are they valuable evidence in the file?

Registration procedures are carried out through MERSİS; registered commercial enterprises, companies, and their branches are assigned a MERSİS number upon registration. The branch MERSİS number is created by adding a sequence number to the head office's MERSİS number.

Although it may seem like a technique, it's very useful in practice:

• The first step in checking whether different locations using the same brand are truly "branches, franchises, or independent businesses" is..

• Identity verification in banks and public institutions,

• Correct debtor/title identification in enforcement proceedings,

• In cases arising from branch operations, proving which unit the dispute relates to.

7) Representation and Signing Authority in Branch Operations: Can the "Branch Manager" Do Everything?

The authority of those conducting transactions at the branch is, as a rule, the will of the head office and the registered representation/binding arrangement. The authority granted to the branch manager is often limited to "branch business only"; the enforceability of this limitation against third parties is related to its registration and visibility.

Therefore, when opening a branch, not only the address and activity but the identity and manner of representation of the persons authorized to represent the branch must be correctly established (otherwise, disputes over signatures and allegations of unauthorized transactions will escalate).

8) Jurisdiction (Code of Civil Procedure, Article 14): Where is the Branch Filed in the Lawsuit?

The most significant aspect of the distinction between the central office and branches that "changes the outcome of a case" is often jurisdiction. According to Article 14/1 of the Code of Civil Procedure , in cases arising from the actions of a branch, the court of the location of the branch also has jurisdiction.

This rule has practical consequences such as the following:

• If the contract was concluded at the branch or the performance took place at the branch,

• If the invoice/delivery/defect notification was processed through the branch,

• If the payment was made through the branch cash register/branch account,

The plaintiff may have the option of filing a lawsuit not only at the headquarters but also at the location of a branch . Jurisdiction strategy (especially in commercial cases, due to factors such as speed, expert network, and court practice) is often determined at this point.

9) The Most Common Mistake in Practice: Calling it a "Contact Office" but effectively operating it like a branch

Some businesses open a location under the name of "liaison office" to delay registration processes or for financial/operational reasons; however, if sales are made, contracts are signed, and payments are collected there, it effectively strengthens its status as a branch. In the Ministry of Trade's evaluation of branches, the independent establishment of legal transactions with third parties and the conduct of commercial/industrial activities are among the main criteria supporting the status of a branch.

Therefore, businesses should position themselves based on their actual operations , not on "labeling."

10) Practical Checklist for Branch Opening

1. Decision of the authorized body regarding the opening of the branch (according to the type of company)

2. Branch address and scope of activity (NACE/subject compliance)

3. Person(s) authorized to represent the branch and form of representation

4. The branch name should be structured to be consistent with the head office name (branch designation + additions if necessary)

5. Commercial registry registration and publication procedures (at the branch location)

6. MERSİS number and branch number check

7. Standardization of company names in outward-facing documents such as contracts/letterheads/invoices/email signatures

Conclusion

The distinction between the head office and branches of a commercial enterprise is not merely a matter of "address"; the transparency function of the commercial registry, the correct use of the company name, MERSİS (Turkish Commercial Registry System) identification, representation and signature security , and jurisdiction to sue . Considering the legal requirements regarding branch registration and branch names (Turkish Commercial Code Articles 40 and 48) and the definition and registration logic of branches in the Commercial Registry Regulation, businesses must establish their branch structures in a way that is "compatible with actual business activity" and does not generate legal risk.
