§48-5-405. Amendments to pleadings.
Amendments to pleadings in an action for divorce are permitted
upon the same general considerations which govern the practice in
other proceedings, and are properly allowed for the purpose of
making the allegations of the pleading more definite and certain,
of asserting an essential allegation which has been omitted, or of
including allegations of misconduct committed subsequent to the
commencement of the action.
