[840] In early German law the "real contract" is the only contract recognized. There is no contract by mere convention, no "consensual" contract. Originally two-sided fulfilment was required. Thus, according to SOHM, _Eheschliessung_, 24 ff., in case of betrothal, payment of the price and tradition of the bride went hand in hand. Later one-sided performance, or even a formal act, was deemed sufficient, and through it the _title_ was actually transferred; the purchaser thus acquiring the "negative" as opposed to the "positive" rights of property--the power to use and enjoy. _Cf._ HABICHT, _Altdeutsche Verlobung_, 6, 7; LOENING, _Geschichte des deutschen Kirchenrechts_, II, 577-79; YOUNG, in _Essays_, 167; LEHMANN, _Verlobung und Hochzeit_, 77; FRIEDBERG, _Verlobung und Trauung_, 7, 8; STOBBE, _Reuerecht und Vertragschluss nach älterem deutschem Recht_ (Leipzig, 1876). [841] Anglo-Saxon _weotuma_: ÆLFRED, _Ecc. Laws_, 12, 29: SCHMID, _Gesetze_, 58, 62. SCHROEDER uses the term _Muntschatz_, which, however, is only found in Friesic law: SOHM, _Eheschliessung_, 33, note. Some form of _weotuma_ appears in many dialects: Old German _widemo_, giving rise to _Witthum_; Longobardian _meta_; Burgundian _wittemon_; Friesic _wetma_ (_wethma_, _weetma_); Alamannian _widem_: SCHROEDER _Güterrecht_, I, 46, 47, 24; SCHMID, _op. cit._, 675; GRIMM, _Rechtsalterthümer_, 422-24; YOUNG, in _Essays_, 165; WEINHOLD, _Deutsche Frauen_, I, 320, note, 336, _passim_; SCHROEDER, _Rechtsgeschichte_, 291, note, 161. _Cf._ ECKHARDT, "Das Witthum," in _Zeitsch. für deutsches Recht_, X, 437 ff.; HELLWALD, _Die mensch. Familie_, 315, 316; SMITH, _La famille chez les Burgondes_, 5 ff.
