Short answer
A clinic’s website disappearing or a brand name changing does not, by itself, establish that the legal entity closed or determine who may be responsible. Start with the names on your contract, invoice and medical records, then verify company information through official trade-registry channels and obtain case-specific advice.
Updated: 25 September 2026. This is general legal information, not advice on an individual matter.
Separate the brand from the legal provider
Patients often remember the clinic’s public brand, while contracts, invoices and medical records may show a company name, hospital operator or separate provider. A booking intermediary may also appear. These names may relate to different roles, so list each one separately before contacting anyone.
A website that no longer loads, a social account that is inactive or a changed signboard is not enough to determine a company’s legal status. A company may have changed its trade name, moved, transferred a brand or stopped providing one service while continuing to exist. Verification should come from official records and the underlying documents.
Do not assume that a new company using a similar brand automatically takes on another entity’s obligations. Whether a transfer, merger, succession or other legal relationship matters requires a review of company records and the facts.
Collect the documents that identify each entity
- Signed treatment or package agreement, including every page and annex.
- Invoice, receipt, card statement and the legal name shown as the payee.
- Medical records showing the facility, treating clinicians and service dates.
- Booking emails, messages and website pages identifying the clinic or intermediary.
- Discharge documents, prescriptions and any referral to another facility.
- Any written notice about a name, address, ownership or operating change.
Keep the documents as received. Create a separate index with the name, document type and date. If different names appear, note where each one appears and do not choose one as “the clinic” until the relationship is checked.
Use official company information carefully
The Ministry of Trade’s Central Registry Record System (MERSİS) and the Trade Registry Gazette can help verify company identity and published registry information. Search using the exact legal name or registry number from your invoice or contract where possible. The Ministry of Trade notes that some MERSİS company queries require a logged-in user. Save the date of your search and the result you consulted.
For providers operating within international health tourism, the 2025 International Health Tourism and Tourist Health Regulation includes requirements about the name and title shown on a facility or intermediary website matching the authorised title and ownership name. Whether that regulation applies to the entity and period relevant to your treatment should be checked.
Public registry information is a starting point, not a complete legal opinion. A result may not explain which entity contracted with you, who delivered care, whether a proceeding is available or which party should receive a formal notice.
What to do if you cannot get a reply
Send a factual written request to the verified address or channel listed in the records. Ask for the complete medical file and confirmation of the legal entity that provided the clinical service. Keep delivery evidence and any returned or undeliverable message.
If the provider does not respond, record the dates and avoid sending sensitive medical details to unverified contacts. A lawyer can help determine whether another facility, registered address, representative or official route should be used. If you need care, contact an appropriate clinician; do not wait for a legal response to address a health concern.
If you are missing the clinical file, use our medical-record request checklist. If a clinic has blocked you rather than formally closed, see what to preserve when a clinic stops responding.
Do not let an entity search delay a time-sensitive review
Claim routes, parties and time limits can depend on the provider’s legal form, the treatment relationship, the type of alleged act and other facts. This article does not calculate any deadline or conclude that a claim can or cannot proceed. Preserve the records and get advice promptly if you are concerned about time.
For an initial consultation, prepare the exact provider names, the documents where you found them, a treatment timeline and any registry information you located. This helps counsel distinguish a trading brand from the entities shown in formal records.
Frequently Asked Questions
Can I pursue a case if the clinic has closed?
A closure or website change does not answer that by itself. The legal entity, its status, the treatment relationship and the applicable procedure need to be checked.
Where can I check a Turkish company name?
The Ministry of Trade’s MERSİS and Trade Registry Gazette are official starting points. Search with the exact legal name or registry details where possible.
Does a new company with the same brand inherit the old clinic’s obligations?
Not automatically. Any legal relationship or transfer needs specific review; a similar brand alone is not enough.
Should I keep contacting a closed clinic’s staff personally?
Use verified formal contact details and avoid sharing sensitive health information with unverified accounts. Ask counsel about the appropriate next contact route.
