in the law of inheritance, succession to property that has not been disposed of by a valid last will or testament. Although laws governing intestate succession vary widely in different jurisdictions, they share the common principle that the estate should devolve upon persons standing in some kinship relation with the decedent. Modern laws of intestacy have tended not to emphasize the traditional concern that property be kept within the bloodline through which it came to the decedent. Modern practice also tends to favour the rights of the surviving spouse, whether or not he or she is regarded as kin, and (in most jurisdictions) to ease restrictions on inheritance by illegitimate children.
