上述術(shù)語均與婚姻關(guān)系有關(guān)，divorce( “離婚”）和annulment (“宣布婚姻無效”）的區(qū)別在于divorce指的是終止一種合法的婚姻地位[1]；而annulment則是確認(rèn)此種合法地位從未存在過[2]。dissolution ( “解除婚姻關(guān)系”），多被認(rèn)為是divorce的一 種委婉說法，也是指終止一種合法的婚姻地位（其也包括因配 偶死亡而使婚姻關(guān)系解除。須注意的是，Black's Law Dictionary 第 6 版說其不包括 annulment；但 A Dictionary of Modem Legal Usage卻認(rèn)為其包括annulment [4])。在涉及離婚時(shí)，人們一般用 divorce,而不用dissolution of marriage；但在美國，無過錯(cuò)離婚或除“感情破裂而無法重修舊好”外的不列舉具體離婚原因之“離婚”，卻通常不稱 divorce 而稱 dissolution of marriage。
