Northern Thailand — Chiang Mai
Checking title, documents and transfer before a major payment is made.

Chiang Mai is the administrative, academic and tourism hub of northern Thailand and home to a large long-stay foreign community. Legal work here spans local business and land matters as well as documents, visas, marriage and succession for long-term foreign residents. Because regional courts and agencies are located in the province, many matters can be completed locally without travelling to Bangkok.
Foreign nationals may own condominium units in Thailand under the Condominium Act, provided foreign ownership in the building does not exceed 49% of the total unit floor area and the funds are evidenced as foreign currency remitted into Thailand as the law requires. We verify the foreign quota, the title status, encumbrances and the sale and purchase agreement, and handle the transfer at the Land Office.
Jurisdiction and filing requirements should be confirmed for each matter, because practice and required attachments differ between offices.

Timeframes are indicative and depend on the court calendar and the authority handling the matter in Chiang Mai.

Specify transfer-day documents, including the foreign-quota certificate from the condominium juristic person.
These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Situation: A foreign buyer has paid a deposit, then learns the building’s foreign quota is full.
Usual approach: Obtain the quota certificate before paying a deposit, and state in the sale agreement that the buyer may terminate and reclaim the deposit if the foreign quota is unavailable. (Hypothetical.)

Most matters can be handled locally: Chiang Mai has provincial, municipal, family, regional labour and administrative courts as well as a legal execution office. Exceptions are matters the law assigns to central bodies, such as MFA document legalisation.
Yes. The document must follow the correct Thai statutory form, and if it will also be used abroad, translation and certification should be planned from the outset to avoid redoing it.
Check the title type, legal access, zoning and use restrictions, and any registered encumbrances before paying a deposit — these are hard to fix after signing.
As a rule foreigners cannot own land. Common alternatives are owning the building while taking a long lease of the land, or using a usufruct or superficies right — each with different limitations.
Not necessarily; a power of attorney can be used. A power of attorney executed abroad normally needs signature certification and embassy or competent-authority authentication before it can be used in Thailand.
It is a matter of contract. Parties commonly split the costs or allocate them to one side, so the allocation should be stated clearly before signing.
