Land Act Article 69

If any error or omission in registration is discovered by the registration officer or an interested party after registration has been completed, no rectification shall be made until the said error or omission has been reported in writing to the competent superior authorities and they, after due investigation, have approved of the rectification. Unless the error or omission in registration is purely the negligence of the registration officer when he enters the registration, and there are original documents of evidence citing reasons for registration for examination, the Land Office should be rectified directly.
中文原文 土地法第69條
登記人員或利害關係人,於登記完畢後,發見登記錯誤或遺漏時,非以書面聲請該管上級機關查明核准後,不得更正。
但登記錯誤或遺漏,純屬登記人員記載時之疏忽,並有原始登記原因證明文件可稽者,由登記機關逕行更正之。
