Legitime

In Civil law and Roman law, the legitime (legitima portio), also known as a forced share or legal right share, of a decedent's estate is that portion of the estate from which he cannot disinherit his children, or his parents, without sufficient legal cause. The word comes from French héritier légitime, meaning "rightful heir."

The legitime is usually a statutory fraction of the decedent's gross estate and passes as joint property to the decedent's next-of-kin in equal undivided shares. The legitime cannot be infringed in order to give a spouse or other beneficiary a greater share of the estate. Therefore, when a decedent has children and leaves a will, it is unlawful for the testator to override the legitime by special gift which exhausts the estate or by designating his spouse or other person as sole beneficiary. This is known as preterition when arising by omission and disinheritance when heirs are expressly deprived.

English Common law

In English common law, there is no legitime; the Statute of Wills, 32 Hen. VIII c. 1, provided for the unfettered distribution of a decedent's entire estate; a testator is entitled to disinherit any and all of his children, for any reason and for no reason. Most jurisdictions in the United States have enacted statutes that prohibit a testator from disinheriting a spouse, or provided that in the event of such a will the spouse may elect to "take against the will" and claim a statutory share of a decedent's estate. This is done as a substitute for the common law rights of dower and curtesy.
