By providing details like the survey number or property address, you can request information about the last recorded survey. Additionally, the local Sub-Registrar’s Office or the District Survey Office may have archived survey documents.​

3. Contact Previous Owners or Licensed Surveyors

They may possess copies of past surveys or can provide information about when the last survey was conducted. Alternatively, hiring a licensed surveyor to perform a new survey ensures up-to-date and accurate boundary information, especially if significant time has passed since the last survey or if the property has undergone changes.
