EXCAMBION, in Scots law, the exchange (q.v.) of one her itable subject for another [from Lat. canabire, possibly from Gr. to bend]. The modern Scottish excambion may con sist in the exchange of any heritable subjects whatever, e.g. a patronage or, what often occurs, a portion of a glebe for servi tude. Writing is not, by the law of Scotland, essential to an excambion. Power to excamb was applied to an entailed estate by the Rutherford Act of 1848, and the necessary consents of heirs were regulated by the Entail (Scotland) act of 1882.
