If a man proves to be a habitual beater of his wife, being without self-control and fierce (2 Tim. 3:3), and he does not conform to the Scriptural counsel that was given by the older men in the congregation, the violent man can be disfellowshipped.
... If the injured wife then decides to institute some court action against her disfellowshipped husband, feeling this to be necessary to protect herself from violence, this would not be out of line with the counsel recorded at 1 Corinthians 6:1-6.
