Ala. Code § 6-6-312

Where title or possession of the premises is held by several persons jointly, as by tenants in common, coparceners, partners, or other joint occupancy or title, they are seized for themselves and for each other; all are equally entitled to possession; and, conversely, the possession of any one is the possession of all; and any joint tenant may commence an action of forcible entry and detainer against a stranger and recover the entire possession, which inures to the benefit of all.
