Thirty-Year Registered Lease Agreement and Instructions (Thailand, Bilingual EN-TH)
Thirty years is the longest lease of a home Thai law allows (section 540 of the Civil and Commercial Code), and it binds a later owner of the property for the whole term only when it is registered at the Land Office: unregistered, it can be enforced for three years only (sections 538 and 569). A tenant who pays 30 years of rent in advance needs more than the short official form: the right to improve the house, a rule for repairs and for a fire, the right to resell the remaining years, protection if the owner sells or if the tenant dies, and a renewal clause that says honestly what it can and cannot do after Supreme Court decision 4655/2566. This pack gives you two documents: the agreement itself, and plain instructions to complete it, sign it and register it.

Who it is for
An owner and a tenant, often a foreigner, who have agreed a long lease of a house, a villa or a condominium unit that already exists. For bare land on which the tenant will build, use the Land Lease Agreement with Right to Build. For a rental of up to 3 years, use the House and Apartment Lease Agreement.
