摘要：

法律行为的原因、内容、条件、负担以及当事人的动机等因素违反公序良俗时，不仅各自的表现样态存在区别，对法律行为无效性的影响也不相同。法律行为的原因或内容违反公序良俗的，法律行为全部或部分无效。停止条件违反公序良俗的，法律行为全部无效；解除条件违反公序良俗的，原则上仅解除条件无效。慷慨行为中的负担违反公序良俗的，仅负担本身无效。多方法律行为当事人的共同动机或者单方法律行为当事人的动机违反公序良俗的，法律行为全部无效。我国在编纂民法典时，应当就法律行为的内容、条件、负担和当事人的动机违反公序良俗的情况及其相应的法律效果分别加以规定。

Abstract:

When the causes，contents，conditions or charges of juridical acts and motives of the parties violate public order and good morals，there are not only differences in their respective manifestations，but also different effects on the invalidity of juridical acts.If the causes or contents of a juridical act violate public order and good morals，the juridical act is void in whole or in part.If the suspensive condition of a juridical act violates public order and good morals，the entire juridical act is void.If the resolutory condition of a juridical act violates public order and good morals，generally only the resolutory condition alone is void.If the charge of a generous juridical act violates public order and good morals，only the charge alone is void.If the common motives of two or more parties of a bilateral juridical act or the motive of the party of a unilateral juridical act violate public order and good morals，the juridical act is void in whole.During the process of making Civil Code in China，the Code should stipulate separately those respective manifestations for contents，conditions and charges of juridical acts and motives of the parties which violate public order and good morals，and should also stipulate their corresponding legal effects separately.
