§48-5-202. Grounds for divorce; voluntary separation.
(a) A divorce may be ordered when the parties have lived separate and apart in separate places of abode without any cohabitation and without interruption for one year. The separation may occur as a result of the voluntary act of one of the parties or the mutual consent of both parties.

(b) Allegations of res judicata or recrimination with respect to any other alleged grounds for divorce are not a bar to either party obtaining a divorce on the ground of voluntary separation.

(c) When required by the circumstances of a particular case, the court may receive evidence bearing on alleged marital misconduct and may consider issues of fault for the limited purpose of deciding whether spousal support should be awarded. Establishment of fault does not affect the right of either party to obtain a divorce on the ground of voluntary separation.
