论诉讼时效的法定性

时效制度的法定性要求诉讼时效的期间、计算方法以及中止、中断等障碍性事由应当一概由法律予以明确规定,当事人不能预先放弃时效利益,也不能约定延长或者缩短诉讼时效期间。在实践中,对于是否允许当事人约定改变诉讼时效期间以及是否允许当事人预先放弃诉讼时效利益两个问题存在着争议。不应允许当事人随意通过协议改变诉讼时效期间,诉讼时效利益也不可预先抛弃。对于时效期间届满后的诉讼时效利益允许义务人自由处分。

On the statutory limitation of action

The statutory limitation system required the limitation period,calculation methods,and other barrier reasons to suspend,interrupt should be defined solely by the law,the parties can not pre-give up the limitation interests,can not agree to extend or shorten the limitation of action. In practice,there are controversy on whether to allow the parties agreed to change the limitation period,and whether to allow the parties to give up the interests in advance.The parties should not be allowed to change arbitrarily the limitation period by agreement,and the interests of limitation must not be abandoned in advance.The limitation interests after the expiration of the limitation period are allowed to freely manage by the obligor.
