CCC Section 237: can a creditor unwind the transfer that put your land in the seller's hands?

Can someone else's old, unrelated debt undo a purchase you had nothing to do with? Under Civil and Commercial Code Section 237, a creditor can go to court to cancel a juristic act — a gift, an undervalue sale, a transfer into a relative's name — that a debtor made while knowing it would prejudice that creditor. It's a real mechanism, not a theoretical one, and it reaches backward through a chain of title further than most buyers assume.

What Section 237 actually allows

• Section 237 — a creditor may sue to cancel any juristic act the debtor did knowing it would prejudice the creditor. This doesn't apply if the person who benefited didn't know, at the time, the facts making it prejudicial — except for a gratuitous act (a gift), where the debtor's own knowledge alone is enough to void it.
• Section 238 — cancellation can't touch the right of a third party who acquired it in good faith and for value. That protection disappears if the third party got the right gratuitously (a further gift down the chain).
• Section 239 — a successful cancellation benefits all of the debtor's creditors, not just the one who sued.
• Section 240 — the claim is time-barred one year after a creditor discovers the grounds for cancellation, or ten years after the act itself, whichever comes first.

Why this matters for chain-of-title on Koh Phangan

Picture a plot that changed hands as a suspiciously cheap 'sale' or an outright gift shortly before your seller acquired it — perhaps from someone facing a lawsuit, unpaid debts, or (amid 2026's intensified enforcement) a company under scrutiny for nominee shareholding or Section 94 disposal. If that earlier transfer prejudiced a creditor, Section 237 lets that creditor sue to cancel it — and if it's cancelled, everything registered afterward in that chain is built on a title that no longer legally exists at that link.

The buyer's shield: good faith and value

This is where Section 238 matters. If you registered your own purchase for a real price and in genuine good faith — without knowing about the earlier prejudicial act — your right generally survives even if an earlier link in the chain gets cancelled. The buyer with no protection at all is the one who received the land as a gift, or at a price so far below market that a court could treat it as effectively gratuitous: a gratuitous recipient gets no Section 238 shield, no matter how far down the chain they sit.

What this means for due diligence

• Check how your seller acquired the land, not just how you're acquiring it — a registered sale at a plausible market price is far safer than a gift or a fire-sale transfer shortly before a change of hands.
• Ask how recently that prior transfer happened. Section 240's ten-year outer limit means a transfer from decades ago is settled; one from the last one to ten years is still theoretically exposed.
• Have your lawyer check for pending lawsuits or a [Section 83 caveat](/knowledge/land-code-section-83-caveat-title-deed) against any prior owner in the chain, not only the current seller — a caveat or an active claim is the clearest sign a creditor is already circling.
• Treat this as a separate risk layer from [AMLA civil forfeiture](/knowledge/amla-civil-forfeiture-bona-fide-purchaser-thailand) — that mechanism reaches assets linked to a predicate crime through a different statute; Section 237 requires only an ordinary civil debt and a prejudicial transfer, a lower and more common bar.

Section 237 isn't a reason to distrust every transaction — most Thai land changes hands through an ordinary, arm's-length sale that this provision never touches. But it's a concrete reason why due diligence on Koh Phangan should look one step further back than the seller's own name on the title: at how, and how recently, they got it.
