Article 181: Safeguards for amending pleadings
Statutory text (Thai original)
เว้นแต่ในกรณีที่คำร้องนั้นอาจทำได้แต่ฝ่ายเดียว
(๑) ห้ามไม่ให้มีคำสั่งยอมรับการแก้ไข เว้นแต่จะได้ส่งสำเนาคำร้องให้แก่คู่ความอีกฝ่ายหนึ่งทราบล่วงหน้าอย่างน้อยสามวัน ก่อนกำหนดนัดพิจารณาคำร้องนั้น
(๒) ห้ามมิให้ศาลพิพากษาหรือมีคำสั่งชี้ขาดในประเด็นที่คู่ความได้แก้ไขคำฟ้อง หรือคำให้การ เว้นแต่คู่ความอีกฝ่ายหนึ่งจะได้มีโอกาสบริบูรณ์ในอันที่จะตรวจโต้แย้งและหักล้างข้อหาหรือข้อต่อสู้ใหม่ หรือข้ออ้าง หรือข้อเถียงใหม่ที่กล่าวไว้ในคำร้องขอแก้ไขนั้น
English translation
Except in a case where the motion may be made by one party only: (1) the court shall not order acceptance of the amendment unless a copy of the motion has been served on the other party in advance at least three days before the date fixed for hearing that motion; (2) the court shall not give judgment or a ruling on an issue on which a party has amended the complaint or the answer, unless the other party has had a full opportunity to examine, contest, and rebut the new claim or new defence, or the new allegation or argument, stated in the motion for amendment.

Firm annotation
Section 181 protects the adversarial balance whenever a pleading is amended under Sections 179 and 180. It has two guarantees. First, unless the motion is one that may be made ex parte, the court may not accept the amendment without serving a copy on the other party at least three days before the hearing. Second, the court may not decide any amended issue until the other side has had a full opportunity to examine and rebut the new claim, defence, allegation, or argument. Breach of these safeguards is a procedural irregularity, often addressed together with Section 21 on motions, and can lead an appellate court to revoke the order allowing the amendment.
Why this matters in practice
If your opponent amends, insist on being served and on a proper chance to respond, these are not formalities. An order accepting an amendment without the three-day service, or a judgment on an amended point before you could rebut it, is vulnerable on appeal. Conversely, if you are the one amending, make sure the copy is served and the other side is heard, so your hard-won amendment is not later undone for a procedural slip.

Arrêt de la Cour suprême n° 1347/2557 (2014)
Where the plaintiff amends the complaint, Section 181 (2) entitles the defendant to seek leave to amend the answer and rebut the plaintiff's new allegations. A defendant who does not use that opportunity and consents to proceed is left with its original defence.
After the plaintiff amended its damages claim, the defendant could have moved to amend its answer under Section 181 (2) but did not, and allowed the evidence to be taken and concluded that day. The Court treated the defendant as standing on its original defence.

Arrêt de la Cour suprême n° 5598/2551 (2008)
Correcting a misspelling in the name of the company's authorised director in the complaint is a minor slip. Such an amendment may be made ex parte under Section 21 (2) and Section 181 (1): the court need not serve a copy of the motion on the defendant in advance or give it an opportunity to object.
The plaintiff asked to correct a few misspelled letters in the name of the authorised director who had granted the power of attorney. Applying section 17 of the Act establishing the Tax Court together with Sections 21 (2) and 181 (1) of this Code, the Supreme Court held the correction was a minor slip that could be made ex parte, without advance service on the defendant or any chance for it to object. Since that director had in fact granted the power of attorney, the plaintiff had authority to bring the case.

Arrêt de la Cour suprême n° 551/2550 (2007)
Even where the court has not strictly followed Section 181 (1) before ruling, leave to amend may still be granted where the amendment motion was timely under Section 180, the other party suffered no prejudice, and it could still prove its case.
The objector moved to amend its objection on the limitation point, within the time allowed by Section 180. The Supreme Court held there was good reason to allow the amendment: the amended plea raised the same issue the objector had already taken, changing only the date on which the ground for revocation was said to have become known, and the petitioner opposing the motion, the official receiver, was not put at a disadvantage because it could still prove why its own application was not time-barred.

Foire aux questions
L'autre partie doit-elle être informée d'une motion de modification ?
Oui, sauf si la requête peut être présentée ex parte. En vertu de l'article 181 (1), le tribunal ne peut accepter la modification que si une copie est signifiée à l'autre partie au moins trois jours avant l'audience.
Le tribunal peut-il statuer immédiatement sur un point modifié ?
Non. L’article 181 (2) interdit au tribunal de statuer sur une question modifiée avant que l’autre partie n’ait eu pleinement l’occasion d’examiner et de réfuter la nouvelle demande, défense ou argument.
Que se passe-t-il si ces mesures de protection sont ignorées ?
L'ordonnance acceptant la modification peut constituer une procédure irrégulière et peut être révoquée, souvent analysée conjointement avec l'article 21 sur les requêtes, en particulier lorsque l'autre partie s'est vue refuser la possibilité de répondre.
