Conflict of interest for attorney

my husband is being represented by his new girlfriends ex-boyfriend, the father of her child. This women and her daughter live in my home and she is 6 months pregnant with my husbands child. Can the attorney represent my husband during our divorce and her if I file a motion for criminal conversation. Can he legally and morally represent them both.

Based on those particular facts, I see no legal conflict of interest in her brother representing your husband.
