Verify a Suradeed certificate
A bank, a notary, an agent or a second buyer can check here that a certificate was issued by a partner firm, with no account. You need the dossier reference and the SHA-256 fingerprint printed on the document.
Suradeed coordinates the verification and is not a law firm. Every certificate is signed by a licensed Thai lawyer at a partner firm.
How to check a certificate
- Find the dossier reference on the certificate's first page — the format is SD, the year, then four digits, for example SD-2026-0154.
- Find the SHA-256 fingerprint printed at the foot of the document: 64 letters and digits that identify exactly this version of exactly this file.
- Enter both in the form above and submit. The register answers from Suradeed's own records — no account, no charge, and the check leaves no trace on the dossier.
What a match proves — and what it never does
A match confirms the certificate exists in Suradeed's register: the partner firm that produced it, the licensed lawyer who signed it, the signature date, and whether a newer version has since replaced the one in your hands. A signed certificate is immutable — a correction is always a new version, never an edit — so learning that yours has been superseded is itself part of the answer.
A match never restates what the certificate says. The findings — the title deed's status, registered servitudes, red flags, recommendations — belong to the buyer who commissioned the verification, and only the buyer decides who reads them.
Who checks certificates here
Banks confirming a document before they finance a purchase, notaries and lawyers acting for a counterparty, estate agents handed a certificate mid-negotiation, and second buyers who received a report from a seller and want to know it is genuine before relying on it.
If the register finds nothing
First rule out a typing slip — the fingerprint must be all 64 characters, and a single wrong character is enough for no match. If both values are correct and the register still finds nothing, do not rely on the document: it was not issued through Suradeed, or it was altered after signature. Ask whoever gave it to you for the original PDF file rather than a scan or a screenshot.
Behind the register
Every certificate is produced under a published, versioned methodology and cites the version it was produced under. The register keeps the full version history of each dossier's certificate — which is why it can tell you not only that a document is genuine, but also whether it is current.
