Which figure should you trust in a dispute?

Conversions help you understand and compare; they don’t change what your record says. Trust the area in your record of rights and the survey map. If the land on the ground looks smaller than the record, the next step is a demarcation by the revenue office — and if you live abroad, satellite monitoring can flag field-scale change if a neighbour starts using your land.
