marriageable age, whether they be independent or dependent: provided that, in the latter case, they must have the consent of the parents in whose power they respectively are, the necessity of which, and even of its being given before the marriage takes place, is recognised no less by natural reason than by law. Hence the question has arisen, can the daughter or son of a lunatic lawfully contract marriage? and as the doubt still remained with regard to the son, we decided that, like the daughter, the son of a lunatic might marry even without the intervention of his father, according to the mode prescribed by our constitution.
1 It is not every woman that can be taken to wife: for marriage with certain classes of persons is forbidden. Thus, persons related as ascendant and descendant are incapable of lawfully intermarrying; for instance, father and daughter, grandfather and granddaughter, mother and son, grandmother and grandson, and so on ad infinitum; and the union of such persons is called criminal and incestuous. And so absolute is the rule, that persons related as ascendant and descendant merely by adoption are so utterly prohibited from intermarriage that dissolution of the adoption does not dissolve the prohibition: so that an adoptive daughter or granddaughter cannot be taken to wife even after emancipation.
2 Collateral relations also are subject to similar prohibitions, but not so stringent. Brother and sister indeed are prohibited from intermarriage, whether they are both of the same father and mother, or have only one parent in common: but though an adoptive sister cannot, during the subsistence of the adoption, become a man's wife, yet if the adoption is dissolved by her emancipation, or if the man is emancipated, there is no impediment to their intermarriage. Consequently, if a man wished to adopt his son-in-law, he ought first to emancipate his daughter: and if he wished to adopt his daughter-in-law, he ought first to emancipate his son.
3 A man may not marry his brother's or his sister's daughter, or even his or her granddaughter, though she is in the fourth degree; for when we may not marry a person's daughter, we may not marry the granddaughter either. But there seems to be no obstacle to a man's marrying the daughter of a woman whom his father has adopted, for she is no relation of his by either natural or civil law.
4 The children of two brothers or sisters, or of a brother and sister, may lawfully intermarry.
5 Again, a man may not marry his father's sister, even though the tie be merely adoptive, or his mother's sister: for they are considered to stand in the relation of ascendants. For the same reason too a man may not marry his great-aunt either paternal or maternal.
6 Certain marriages again are prohibited on the ground of affinity, or the tie between a man or his wife and the kin of the other respectively. For instance, a man may not marry his wife's daughter or his son's wife, for both are to him in the position of daughters. By wife's daughter or son's wife we must be understood to mean persons who have been thus related to us; for if a woman is still your daughterinlaw, that is, still married to your son, you cannot marry her for another reason, namely, because she cannot be the wife of two persons at once. So too if a woman is still your stepdaughter, that is, if her mother is still married to you, you cannot marry her for the same reason, namely, because a man cannot have two wives at the same time.
7 Again, it is forbidden for a man to marry his wife's mother or his father's wife, because to him they are in the position of a mother, though in this case too our statement applies only after the relationship has finally terminated; otherwise, if a woman is still your stepmother, that is, is married to your father, the common rule of law prevents her from marrying you, because a woman cannot have two husbands at the same time: and if she is still your wife's mother, that is, if her daughter is still married to you, you cannot marry her because you cannot have two wives at the same time.
8 But a son of the husband by another wife, and a daughter of the wife by another husband, and vice versa, can lawfully intermarry, even though they have a brother or sister born of the second marriage.
9 If a woman who has been divorced from you has a daughter by a second husband, she is not your stepdaughter, but Iulian is of opinion that you ought not to marry her, on the ground that though your son's betrothed is not your daughterinlaw, nor your father's betrothed you stepmother, yet it is more decent and more in accordance with what is right to abstain from intermarrying with them.
10 It is certain that the rules relating to the prohibited degrees of marriage apply to slaves: supposing, for instance, that a father and daughter, or a brother and sister, acquired freedom by manumission.
11 There are also other persons who for various reasons are forbidden to intermarry, a list of whom we have permitted to be inserted in the books of the Digest or Pandects collected from the older law.
12 Alliances which infringe the rules here stated do not confer the status of husband and wife, nor is there in such case either wedlock or marriage or dowry. Consequently children born of such a connexion are not in their father's power, but as regards the latter are in the position of children born of promiscuous intercourse, who, their paternity being uncertain, are deemed to have no father at all, and who are called bastards, either from the Greek word denoting illicit intercourse, or because they are fatherless. Consequently, on the dissolution of such a connexion there can be no claim for return of dowry. Persons who contract prohibited marriages are subjected to penalties set forth in our sacred constitutions.
13 Sometimes it happens that children who are not born in their father's power are subsequently brought under it. Such for instance is the case of a natural son made subject to his father's power by being inscribed a member of the curia; and so too is that of a child of a free woman with whom his father cohabited, though he could have lawfully married her, who is subjected to the power of his father by the subsequent execution of a dowry deed according to the terms of our constitution: and the same boon is in effect bestowed by that enactment on children subsequently born of the same marriage.
TITLE XI. OF ADOPTIONS
Not only natural children are subject, as we said, to paternal power, but also adoptive children.
1 Adoption is of two forms, being effected either by rescript of the Emperor, or by the judicial authority of a magistrate. The first is the mode in which we adopt independent persons, and this form of adoption is called adrogation: the second is the mode in which we adopt a person subject to the power of an ascendant, whether a descendant in the first degree, as a son or daughter, or in a remoter degree, as a grandson, granddaughter, great-grandson, or great-granddaughter.
2 But by the law, as now settled by our constitution, when a child in power is given in adoption to a stranger by his natural father, the power of the latter is not extinguished; no right passes to the adoptive father, nor is the person adopted in his power, though we have given a right of succession in case of the adoptive father dying intestate. But if the person to whom the child is given in adoption by its natural father is not a stranger, but the child's own maternal grandfather, or, supposing the father to have been emancipated, its paternal grandfather, or its great-grandfather paternal or maternal, in this case, because the rights given by nature and those given by adoption are vested in one and the same person, the old power of the adoptive father is left unimpaired, the strength of the natural bond of blood being augmented by the civil one of adoption, so that the child is in the family and power of an adoptive father, between whom and himself there existed antecedently the relationship described.
3 When a child under the age of puberty is adopted by rescript of the Emperor, the adrogation is only permitted after cause shown, the goodness of the motive and the expediency of the step for the pupil being inquired into. The adrogation is also made under certain conditions; that is to say, the adrogator has to give security to a public agent or attorney of the people, that if the pupil should die within the age of puberty, he will return his property to the persons who would have succeeded him had no adoption taken place. The adoptive father again may not emancipate them unless upon inquiry they are found deserving of emancipation, or without restoring them their property. Finally, if he disinherits him at death, or emancipates him in his lifetime without just
