由唐代有关卖买契约的令文及有关律文规定,可见当时卖买契约与国家法律的基本关系。唐代卖买契约,基本是依照法律令进行的程序和活动,是在法律指导下形成的秩序。在此方面,古代契约活动的依据,主要为国家法,而非所谓民间法。 From the Tang Dynasty to sell the contract to buy the text and the relevant provisions of the law, we can see the then sell contract and the basic relationship between national law. The contract of sale and purchase in the Tang Dynasty was basically the procedure and activity carried out in accordance with the law and was the order formed under the guidance of law. In this respect, the basis of ancient contractual activities was mainly state law, not so-called civil law.
