English translation
If in any judgment or order there is a minor error or other minor slip, and there has been no appeal or further appeal against that judgment or order, the court that gave the judgment or made the order may, where it sees fit or on the application of a party concerned, make an order to correct such error or slip so as to be correct. But if there has been an appeal or further appeal against that judgment or order, the power to correct the error or slip belongs to the appeal court or the Supreme Court, as the case may be. An application to correct the error or slip shall be filed with such court, either stated in the memorandum of appeal or further appeal, or made as a separate application. The making of a supplementary order under this section must not reverse or amend the decision in the original judgment or order. Once such an order has been made, it is prohibited to make a copy of the original judgment or order unless a copy of the supplementary order is included with it.

Firm annotation
Section 143 provides a narrow route to correct minor errors and slips in a judgment or order without disturbing the decision itself. The power belongs to the court that gave the judgment while no appeal is pending, and passes to the appeal court or Supreme Court once an appeal is filed, with the correction sought either in the memorandum or by separate application. The critical limit is that a supplementary order may not reverse or amend the substance of the decision, so Section 143 cannot be used to reargue the merits or fix a genuine adjudication error. It works alongside Section 144, which bars reopening a decided matter except as this and other listed provisions allow.
Why this matters in practice
If a judgment contains an obvious slip, such as a mistyped figure or name that does not change the outcome, Section 143 lets you ask the court to correct it without a full appeal. But the limit is strict: this cannot be used to change the actual decision, and errors that are really your own, or that belong to the enforcement stage, fall outside it. Frame any application as a true clerical correction and file it with the right court depending on whether an appeal is pending. If a judgment has a problem that goes to the merits, an appeal, not a Section 143 request, is the route, and you can discuss options in a consultation with a Thai lawyer.
Supreme Court decisions interpreting this section
-
Supreme Court Judgment No. 99/2568 (2025)
An error that is the party's own mistake, rather than a minor error or slip in the court's judgment, cannot be corrected under Section 143.
The plaintiffs asked to correct a title deed number, but the mistake was in their own application to have the defendants evicted, not in the court's judgment. The Supreme Court held this was not a minor error or slip within Section 143, so it could not correct it as requested.
-
Supreme Court Judgment No. 4819/2566 (2023)
A request that the court decide issues and content it allegedly failed to address is not a case of a minor error or slip, so it does not fall within Section 143.
The plaintiff asked the court to amend its judgment on the ground that it had not decided the issues and substance of the claim. The court held this was not a matter of correcting a minor error or slip under Section 143 and dismissed the application, a conclusion the appeal court affirmed.
-
Supreme Court Judgment No. 1467/2566 (2023)
Where a stated land area in a judgment may be a minor error or slip under Section 143, but the request in substance concerns execution, it is treated as an execution matter rather than a Section 143 correction.
A survey showed the land area differed from the figure in the judgment, which might look like a slip under Section 143. But the court held the application in substance sought directions on execution, so it was an execution matter rather than a Section 143 correction.

Frequently asked questions
Can a court fix a mistake in its own judgment?
Yes, but only minor errors or slips. Under Section 143 the court may correct them on its own or on request, provided the correction does not reverse or amend the actual decision.
Can Section 143 be used to change the outcome of a case?
No. A correction under Section 143 must not reverse or amend the decision. If a party wants to challenge the merits, the proper route is an appeal, not a correction request.
