Tor.Dor.11 (ท.ด.11) is the official Land Department Land Lease Agreement form in Thailand. It bears the Garuda emblem and is the only document legally recognized by the Land Office for the registration of a lease. While parties may draft their own detailed private lease, the Tor.Dor.11 form must be signed at the Land Office for the lease to be valid and enforceable against third parties.
