Note: In some countries, concubinage is marriage of an
inferior kind, or performed with less solemnity than a
true or formal marriage; or marriage with a woman of
inferior condition, to whom the husband does not convey
his rank or quality. Under Roman law, it was the living
of a man and woman in sexual relations without
marriage, but in conformity with local law.
2. (Law) A plea, in which it is alleged that the woman suing
for dower was not lawfully married to the man in whose
lands she seeks to be endowed, but that she was his
concubine.
