按當事人約定一方對於他方於一定擔保事故發生時，即應為一定之給付者，稱為擔保契約。此項契約具有獨立性，於擔保事故發生時，擔保人即負有給付之義務，不以主債務有效成立為必要，自不得主張主債務人所有之抗辯，此與民法上之保證契約具有從屬性或補充性者不同。倘當事人於擔保契約為立即照付之約款，擔保立即照付之義務時，擔保權利人當可依立即照付之形式要件行使權利，無庸對於擔保事項為實質之舉證（最高法院97年度台上字第838號、102年度台上字第584號判決參照）。又按解釋意思表示，應探求當事人之真意，不得拘泥於所用之辭句，民法第98條定有明文。所謂探求當事人之真意，乃在兩造就其意思表示真意有爭執時，應從該意思表示所植基之原因事實、經濟目的、社會通念、交易習慣、一般客觀情事及當事人所欲使該意思表示發生之法律效果而為探求，並將誠信原則涵攝在內，藉以檢視其解釋結果是否符合公平原則。 作者: sec2100 時間: 2021-5-22 19:20
