Land and building identification (土地家屋の表示に関する登記) and map preparation
Scope
The 表示に関する登記 domain covers 表題登記 for land and buildings, 分筆・合筆, 建物の滅失, and the drawings that must accompany them: 地積測量図, 建物図面 and 各階平面図.
Core rules
- Land 表題登記 (法37条) and building 表題登記 (法36条) are the owner's duty, within one month of acquiring ownership.
- 地積測量図 must show 地番, 地積 and 求積方法, boundary-point distances, 座標値 where available, 縮尺, 方位 and the 作成者; a version with coordinates is far more persuasive.
- Building 表題登記 needs a 建物図面 (配置) and 各階平面図. For 一棟の建物, 床面積 is measured to 壁芯; for a 区分建物's 専有部分, to 内法.
- 分筆 requires a new 地積測量図; 合筆 does not, but adjoining parcels must share 地目 and, in practice, ownership.
- 建物の滅失登記 follows demolition; a 区分建物 additionally needs the 敷地権 の表示.
Worked example
A two-storey wooden house is completed. Application: 建物の表題登記, applicant the owner, attachments the 建物図面 and 各階平面図 plus the applicant's 住所証明 and, where relevant, 敷地権 の情報. Compute 床面積 to 壁芯 for the whole building and to 内法 for each 専有部分 - mismatches when the 専有部分 are totalled are a classic source of 補正. The 家屋番号 is assigned by the 登記官, not chosen by the applicant.
Traps
- Mixing 壁芯 and 内法 inside one calculation.
- Omitting 求積方法 or 座標値 from the 地積測量図.
- Treating 分筆 and 合筆 as symmetrical procedures.
