定義第二条第一項第二十八号・法令全体に適用
二以上の会社がする合併であって、合併により消滅する会社の権利義務の全部を合併により設立する会社に承継させるもの
略称規定第五百七十五条第一項
合名会社、合資会社又は合同会社（以下「持分会社」と総称する。）を設立するには、その社員になろうとする者が定款を作成し、その全員がこれに署名し、又は記名押印しなければならない。
定款
会社を設立するときに発起人（持分会社では社員になろうとする者）が作成する、会社の根本規則です（会社法第二十六条・第五百七十五条）。目的・商号・本店の所在地・設立に際して出資される財産の価額又はその最低額・発起人の氏名又は名称及び住所は必ず記載します（第二十七条）。株式会社の定款は公証人の認証を受けなければ効力を生じず（第三十条第一項）、成立後は株主総会の決議で変更できます（第四百六十六条）。「定款に別段の定めがある場合を除き」とする規定が多く、会社法がその会社にどう適用されるかを定款が大きく左右します。
会社法第26条・第27条・第30条・第466条・第575条、Wikipedia「定款」を参考にAIが作成。
登記
法務局や地方法務局、その支局・出張所である登記所が備える公の帳簿に記録して、権利や事項を公示することです（不動産登記法第一条・第六条第一項）。土地や建物の所有権、地上権、先取特権、抵当権、賃借権などは不動産登記法に基づいて登記することができ（同法第三条）、商法や会社法などの規定で登記すべき事項は商業登記法に基づいて登記されます（商業登記法第一条）。登記をすると、権利などを第三者に対抗（主張）できるようになります。土地や建物の所有権などの物権を取得したり、失ったり、変更したりしたことは、登記をしなければ第三者に対抗することができず（民法第百七十七条）、会社法の規定で登記すべき事項は、登記の後でなければ、そのことを知らない第三者に対抗することができず、登記の後でも、正当な事由によって登記があることを知らなかった第三者には対抗することができません（会社法第九百八条第一項）。

株主総会
株式会社の株主が集まって会社の基本的な事項を決める機関です。取締役・監査役などの役員を選任し（会社法第三百二十九条第一項）、定款を変更します（第四百六十六条）。取締役会を置かない会社では会社に関する一切の事項を決議でき、取締役会を置く会社では会社法と定款が定める事項に限られます（第二百九十五条）。毎事業年度の終了後に定時株主総会を招集しなければならず、必要があればいつでも招集できます（第二百九十六条）。決議は原則として、議決権の過半数を有する株主が出席し、その議決権の過半数で行います（第三百九条第一項）。
