Pre-Closing Title Search & Notarised Encumbrance Memo for Foreigners — Court-Grade Due Diligence

Why a 30-year title search — isn't the current owner check enough?

Because the **adverse-possession** period under CCC § 1382 is **10 years** for titled land — and chain gaps anywhere in the prior 30 years allow a true possessor to sue to set the title aside. Court-grade title search verifies (1) continuous chain; (2) no sham transfers; (3) no adverse-possession claim still running. Foreign buyers of villas in Phuket, Koh Samui and Chiang Mai face such claims 2–5 years post-closing routinely.

DOL Online is free — why pay a notary?

DOL Online shows only Chanote number, area, current owner and latest mortgage. It does NOT show (1) the 30-year chain; (2) registered leases (only on the physical reverse of the Chanote); (3) usufruct / servitude / superficies; (4) court attachments; (5) forest / SPK overlays; (6) town-plan zoning. A complete check requires on-site work at the provincial Land Office, Royal Forest Department, ALRO, DPT and Fine Arts Department. A notarised Encumbrance Memo is backed by the notary's PI policy (Lloyd's THB 100M) — overseas lenders will not accept a DOL Online screenshot.

Does a notarised Encumbrance Memo substitute for title insurance?

Thailand has **no formal title-insurance market**. A notarised Encumbrance Memo + Lloyd's PI quote on request (phone / LINE / email) M per occurrence is the closest functional substitute. Offshore lenders (DBS, HSBC, Westpac, UBS, JPMorgan PB) use it as a condition precedent in place of title insurance. If the notary errs and the client suffers loss, the PI policy responds — Lawyers Council Notarial Services Regulation B.E. 2546 § 22.

How do you check forest and SPK 4-01 overlays — these are not on DOL?

At the **Royal Forest Department** (for National Reserved Forest), **ALRO** (for SPK 4-01), **DPT** (for town-plan zoning) and the **Fine Arts Department** (for heritage). Each maintains a separate GIS overlay against which we run the plot's GPS coordinates. The output is an overlay map showing % intersection. Any intersection >0% creates revocation risk.

How serious is adverse possession in practice?

Very. CCC § 1382 confers ownership on a person who possesses titled land 'peacefully, openly and with the intention of being owner' for **10 continuous years**. In southern and northern Thailand this is common: the original owner abandons, an occupier farms or builds for a decade, then sues for ownership. Court-grade title search reviews physical-possession evidence (Google Street View, aerial photography, sub-district officer testimony) before transfer.

Risk score 31–60 (major risk) — what to do?

Major risk covers: (1) undischarged mortgage — seller must discharge pre-closing under escrow; (2) live registered lease — renegotiate or accept it survives; (3) servitude crossing the plot — verify scope vs construction plans; (4) pending DPT approval — wait for the decision. Options: an **indemnity agreement** with 10–30% of price held in escrow for 12–24 months, or a **vendor warranty + Lloyd's W&I policy** on deals > THB 100M.

What additional documents do offshore lenders require alongside the memo?

Standard cross-border mortgage pack: (1) **title-search report** (30-year); (2) **notarised Encumbrance Memo + Apostille**; (3) **valuation report** from an SEC-licensed valuer (Knight Frank, CBRE, JLL); (4) **AMLA enhanced-DD source-of-funds affidavit**; (5) **FET form** for every inward wire ≥ USD 50,000; (6) **mortgage-deed draft** (TH + EN); (7) **lender's local counsel opinion** (we issue). HCCH (in force for Thailand 28 February 2027) acceptance of our MFA Bangkok Apostille eliminates the lender's parallel local-counsel step.

Can one notary certify a memo on land anywhere in Thailand?

Yes — a Notarial Attorney's licence is nationwide under Notarial Services Regulation B.E. 2546 § 9. Our Land Office liaison uses local counsel in deal-heavy provinces for speed — Phuket, Krabi, Samui, Pattaya, Chiang Mai, Hua Hin, Khao Yai, Koh Phangan and Koh Tao all have dedicated partners who reach the provincial Land Office within 12 h.

Cost vs Australia / Singapore title insurance — is it worth it?

**Significantly cheaper in Thailand**. AU/SG title insurance is 0.4–0.8% of price (quote on request (phone / LINE / email) M deal = quoted on request). Our notarised memo + title search is quoted on request backed by Lloyd's PI quoted on request M — 5–10× cheaper. But title insurance covers the entire holding period; the memo covers as-of issuance. UHNWI clients typically buy both — the memo to close, the policy from an offshore insurer for long-term hold.

How long is title-search data retained under PDPA?

**10 years** under AMLA § 22 + Revenue Code § 19 (for lender-relied memos). PDPA § 26 purpose-limitation — disclosure only to client + lender + court order + regulators (DOL / AMLO / BOT). ISO 27001 + AES-256 + off-site backup + right-to-erasure on retention expiry.
