Jure uxoris

Jure uxoris (a Latin phrase meaning "by right of (his) wife")[1][2] describes a title of nobility used by a man because his wife holds the office or title suo jure ("in her own right"). Similarly, the husband of an heiress could become the legal possessor of her lands. For example, married women in England and Wales were legally incapable of owning real estate until the Married Women's Property Act 1882.

Kings who ruled jure uxoris were regarded as co-rulers with their wives and are not to be confused with kings consort, who were merely consorts of their wives.[citation needed]
