What 土地家屋調査士 do
An English description is being prepared. Japanese description:
土地や建物などの不動産は、誰の所有物であるかが全て登記簿に登録されている。登記簿には「表題部」、「甲区」、「乙区」の各部分があり、「表題部」には不動産がどこにあり、面積がどのくらいか、どういう使用目的で存在しているか、ということが記載される。
具体的には、依頼を受けて、建物を新築したり増改築した場合や、土地を分割したり合併して土地の面積が変わった場合などに、土地や建物の調査、測量を行い、登記簿への申請手続又は審査請求の手続を行う。
まず、現地で土地の所有者や隣人の立会いのもとで境界を確認し、測量を行う。測量に際しては、トータルステーションやGNSSなどの測量機材を用いて測量を行う。
測量結果をもとにして事務所で計算、製図をして図面を作る。それに基づいて申請のための書類を作成し、法務局に提出する。法務局で登記簿に記載され、登記済証が交付されると土地家屋調査士の仕事は完了する。
また、土地の境界トラブルを回避するため行政が所有者の申請により境界を特定する筆界特定制度においても外部専門家として意見を述べる等の役割を果たしている。
