Online Property Listing Owner Authorization Check Türkiye’s EİDS (Electronic Listing
Online Property Listing Owner Authorization Check Türkiye’s EİDS (Electronic Listing Verification System) is an advertising-authority control under the Ministry of Trade: it helps verify whether the person/business publishing a property listing has owner authorization. It is not proof that the title is clean, the price is fair or the seller can complete every legal act.
For a listing, check that the property and authorization correspond to the actual owner/authorized intermediary and remain valid for the listing being relied on. A screenshot or copied authorization statement should not replace verification through the current official process.
Buyer due diligence remains separate: match the registered owner, representative authority, parcel/independent-unit data and encumbrances before payment or title transfer. EİDS reduces one advertising risk but does not replace TKGM/title checks.
Advertising, brokerage and representation authority
A change of manager, authorised signatory or signature scope must trigger a fresh authority check before commitment. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Advertising authority, brokerage authority and corporate authority are three different questions. The Ministry of Trade introduced EİDS identity verification and then real-estate advertisement authorisation; advertisement-authority verification became mandatory from 1 January 2025.
That proves the route by which an advertisement may be published, not an automatic power for the broker to sell the property, receive the price or sign for the owner. Where a broker is involved, check the brokerage authorisation and office record, then independently verify the registered owner and any representative through TKGM evidence. The key is not merely that a signature or advertisement exists, but that the person acting had the legal capacity and authority for that act, on that date and within that scope. For a company, use MERSİS and the Trade Registry Gazette/registry to identify the legal name, representation structure and published changes, and match the signer to a current authority document or resolution. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
Payment trail and beneficiary proof
Keep a reservation deposit, sale price and brokerage commission separate, and never replace an auditable banking trail with an oral confirmation. The payment path is part of transaction due diligence, not a separate bookkeeping step. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition. Match beneficiary name, bank account, currency, amount and transfer reference to the contract and to the seller or properly authorised recipient, and independently verify any change in payment instructions before sending funds.
A request to use a new account, a third party or a route outside the agreed structure is a stop signal until authority and reason are resolved. TKGM also has specific foreign-exchange purchase-document instructions for foreign transactions where they apply, so not every bank receipt serves the same legal purpose. Preserve the transfer order, bank confirmation, posting evidence and a reference linking the transfer to the exact instalment. The key is not merely that a signature or advertisement exists, but that the person acting had the legal capacity and authority for that act, on that date and within that scope. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost.
