Conjunctio maris et feminae est de jure naturae. Source: 7 Co. 13; Broom, *Legal Maxims* (1874), p. 505; Weisman, 79f Marriage is not a creature of statute but a natural institution recognized and protected by the common law. 4.1.2 Not cohabitation but consent makes marriage. Nuptias non concubitus sed consensus facit. Source: Coke, Co. Litt. 33a; Dig. 50, 17, 30; Jackson, *Latin for Lawyers* (1915), Max. 739 Marriage is constituted by the voluntary agreement of the parties, not by mere cohabitation — consent is its essential element. 4.1.3 Husband and wife are regarded in law as one person. Vir et uxor censentur in lege una persona. Source: Jenk. Cent. 27; Co. Litt. 112; Jackson, *Latin for Lawyers* (1915), Max. 1065; Weisman, 79i At common law, husband and wife form a legal unity — the acts, acquisitions, and obligations of one are attributable to both. 4.1.4 Marriages ought to be free. Matrimonia debent esse libera. Source: Halk. Max. 86; 2 Kent, Comm. 102; Jackson, *Latin for Lawyers* (1915), Max. 568; Weisman, 61l; Weisman, 79d No external compulsion or unreasonable restraint should be placed upon the right to marry — it is a matter of free choice. 4.2.1 The father is he whom the marriage indicates. Pater est quem nuptiae demonstrant. Source: Co.

Haeres legitimus est quem nuptiae demonstrant. Source: Co. Litt. 7; Jackson, *Latin for Lawyers* (1915), Max. 326; Weisman, 58w Inheritance follows lawful marriage — at common law, only those born within wedlock possess inheritable blood.
