Direct answer

Before signing a reservation agreement, confirm the exact unit or land identity, how much is payable, whether the fee is refundable, what deadlines force you into an SPA, and what happens if foreign-proportion capacity, title, or financing fails. A reservation is a private contract—it does not register ownership at the Department of Lands and should not skip basic diligence.

Key takeaways

  1. 1.Reservation fees are often hard to recover—read refund language carefully.
  2. 2.Identify the exact asset before paying.
  3. 3.Build conditions for quota, title, and SPA negotiation failures.
  4. 4.Reservation is not Land Office ownership.
  5. 5.Needs Thai legal review before transactional reliance.

Important terms

Reservation agreement — Short-form contract securing a unit or price in exchange for a fee.

Forfeiture — Loss of the reservation fee if the buyer does not proceed under the contract’s terms.

SPA — Fuller sale and purchase agreement that should follow—and may still be negotiable if the reservation allows.

Detailed answer: what to check before you sign

Sales galleries optimise for speed. Your job is to slow the irreversible parts.

Check at least:

  1. Asset identity — Project, building, unit, area, parking.
  2. Price and fee — Reservation amount, balance schedule, currency.
  3. Refund / forfeiture — Exact triggers in both directions.
  4. Deadline to SPA — What happens if SPA terms are unacceptable.
  5. Foreign condo gates — Ability to terminate if juristic foreign-proportion letter cannot support transfer. (thailand-go-condo)
  6. Cooling-off — Rare in practice; do not assume you have one.
  7. Who receives money — Developer account vs agent account controls.

Registration still happens later at the Land Office. (dol-home)

Step-by-step

  1. Ask for the reservation draft in editable form.
  2. Send it to independent counsel before paying.
  3. Insert or negotiate quota/title failure exits if foreign freehold is intended.
  4. Cap automatic SPA locked-in terms that waive diligence.
  5. Pay only to the correct account after edits are signed.
  6. Diary SPA and payment deadlines immediately.

Hypothetical example

Assumed facts: Buyer signs a one-page reservation with a non-refundable fee and a 7-day SPA deadline. Counsel is abroad and cannot review in time.

Likely outcome: Fee pressure replaces diligence. Avoid this sequencing.

Risks

  • Non-refundable fees on unfinished diligence.
  • Unit bait-and-switch.
  • Paying the wrong person.
  • Assuming reservation creates ownership.

Checklist

  • Unit identity fixed in writing
  • Refund triggers reviewed by counsel
  • SPA deadline realistic for diligence
  • Foreign-proportion failure exit (if relevant)
  • Correct payee account confirmed
  • Reservation is not treated as title

FAQ

Is a reservation legally binding?

Often yes as a private contract. Binding does not mean ownership is registered.

Can I reserve without counsel?

You can, but the fee is frequently the cost of that choice. Prefer review first.

Does reservation secure the foreign quota?

No. Quota evidence for transfer still depends on the juristic letter and law at transfer time.
