The common law of inheritance for land has assumed its final form with six rules. 1) A living descendant excludes his or her own descendants. 2) A dead descendant is represented by his or her own descendants. 3) Males exclude females of equal degree. 4) Among males of equal degree, only the eldest inherits. 6) The rule that a dead descendant is represented by his or her descendants overrides the preference for the male sex. If there were no descendants, the land escheated to its lord. By statute, a conveyance of land which is the inheritance of a minor child by his guardian or lord to another is void. Dower shall not abate because the widow has received dower of another man unless part of the first dower received was of the same tenant and in the same town. But a woman who leaves her husband for another man is barred from dower. A tenant for a term of years who has let land from a landlord shall not let it lie waste, nor shall a landlord attempt to oust a tenant for a term of years by fictitious recoveries. When two or more hold wood, turfland, or fishing or other such thing in common, wherein none knows his several, and one does waste against the minds of the others, he may be sued. Lands which are given to a man and his wife upon condition that if they die without heirs, the land shall revert to the donor or his heir, may not be alienated to defeat this condition. If a man takes land in marriage with a wife, and she dies before him, the land will revert to the donor or his heir, unless the couple has a child, in which case the husband will have the land by the courtesy of the nation for his life before it reverts to the donor or his heir. Young salmon shall not be taken from waters in the spring. A free tenant may alienate his land freely, but if the alienation was for an estate in fee simple [to a man and his heirs, with a full right of alienation by the man otherwise than on his death], the person acquiring the land would hold of the land's lord and not of the person alienating the land. (This halted the growth of subinfeudation and caused services as well as incidents of aids, relief, escheat, wardship, and marriage to go directly to the Chief Lord. It also advantaged the Crown as overlord, which then acquired more direct tenants.)
