English translation
The transfer of an obligation performable to a specific creditor is not valid unless it is made in writing. It can be set up against the debtor or third person only if a notice thereof has been given to the debtor, or if the debtor has consented to the transfer. Such notice or consent be in writing. The debtor is discharged if he satisfies the transferor by way of payment or otherwise before he has received notice of, or has agreed to, the transfer.

Firm annotation
Section 306 is part of Book 2 (Obligations) of the Thai Civil and Commercial Code. This entry is awaiting firm-authored commentary; the statutory text above is verbatim from the Office of the Council of State (OCS Krisdika) Thai source, with the English translation from the FAO/UN FAOLEX repository. Always rely on the Thai original for legal proceedings.
Why this matters in practice
Lawyers: Both the assignment itself and any notice to the debtor must be in writing; oral assignment or oral notice is ineffective. Once proper notice is given, the debtor must pay the assignee and loses the right to pay the assignor. The debtor retains all defences existing before notice. Laypersons: If someone tells you that your debt has been transferred to a new company, insist on written proof of both the assignment and the notice: until you receive that, you are safe to pay the original creditor.
Legislative history
Part of the original Civil and Commercial Code codification; no major subsequent amendment.

Arrêt de la Cour suprême n° 3033/2550 (2007)
A notice of assignment under section 306 must sufficiently identify the specific debt transferred; a general blanket description covering a pool of debts does not satisfy the requirement.
The plaintiff claimed as assignee of a loan receivable from bank D. The written notice of assignment (exhibit J7) described the transferred debts only in general terms referencing a bundle of credit and security agreements without identifying the specific debt in question. The Court held the notice was insufficiently specific to satisfy section 306 and the assignment could not be enforced against the defendant.
-
Arrêt de la Cour suprême n° 4872/2550 (2007)
Once written assignment and written notice to the debtor are completed under section 306(1), the assignor loses all right to receive payment; any execution by the assignor's other creditors against that receivable must fail.
The defendant assigned its right to receive money under a court-approved settlement to company T, which then sent written notice of the assignment to the obligor. The Court confirmed the assignment was perfected under section 306(1): from that point the defendant (assignor) had no right to receive payment and the plaintiff (who sought to intercept the money by execution) had no basis to do so.

Arrêt de la Cour suprême n° 1840/2547 (2004)
A conditional notice of future-debt assignment is effective only when the specified condition (notation on each invoice) is fulfilled for each individual debt.
Company P notified the defendant of an assignment of trade receivables, including future debts, but conditioned notice on the assignor noting the transfer on each invoice. The Court held this was not a blanket notice of all future receivables but a case-by-case notice: each assignment would only be effective against the debtor once the specific invoice bearing the transfer notation was issued and delivered.
