clarification to rectify

Dear Client,
As per the topographical land survey, layout marking and demarcation are done inclusive of roads, plots, commercial spaces and extra spaces for public use etc. The demarcation is almost purely a technical operation, carried out jointly by the surveyors, acting as boundary engineers, of both parties. Post-survey of the land, a unique survey number is given for plots based on the topographical location of the lands. Property demarcation means physically dividing the property into metes and bounds (i.e. area and boundaries of each property will be made), the rules and procedure of which may vary from state to state. Only the recorded owners of the property can apply for demarcation to the Tehshildar/Land Revenue Officer or it can be done on orders from a Court. In the given situation, you visit the office of the Land Revenue Department or Survey Department for more information/clarification and if required, consult with a local Advocate for guidance and steps.

Dear Sir,
You cannot challenge orally you may file representations before concerned authorities then approach Revenue Authorities and Survey Authorities and accordingly get the entries rectified.
