对遗嘱自由进行限制已成为现代社会的趋势,世界大部分国家已制定了特留份来实现这一目的.我国《继承法》中规定了必留份来保护法定继承人的利益,限制遗嘱人的自由。但必留份本身存在着局限,对权利人的保护不彻底。随着社会的发展,出现的新矛盾要求我们建立特留份制度,结合必留份制度来克服这些社会弊端,稳定秩序。 Restricting the will of testament has become the trend of modern society, most countries in the world have made a special part to achieve this goal.China’s “Inheritance Law” provides for the reserved part to protect the legal heir, limit the testator’s free. However, there must be a limitation on the parting of the obligee, and the protection of the obligee is not complete. With the development of society, the new contradictions that emerge require us to establish a system of special surrender and overcome these social malpractices and the order of stability by means of the system of necessary respects.
