Paula Cook has the potential to win millions from Barrino.
"The awards tend to be very large, where the facts tend to be egregious," Baez told ABCNews.com.
Earlier this year, a North Carolina jury awarded 60-year-old Cynthia Shackelford $9 million after she sued her husband's mistress for breaking up her 33-year marriage.
In her current case, Paula Cook appears to be setting the stage for a potential claim against Barrino, whom she alleges met her husband in August 2009, when the singer visited the T-Mobile store where he works. Shortly after, Cook claims Antwaun began frequenting "bars, restaurants, nightclubs and the like," with Barrino.
In the complaint obtained by a Charlotte television station, Cook accused her husband of enjoying "the lavish benefits associated with the high-profile relationship."
"Ms. Barrino flew defendant / husband to places such as Atlanta, Miami, New York, Philadelphia, Los Angeles, and Barbados," she alleged, adding that he "attended celebrity parties, concerts, photo shoots and award shows with Ms. Barrino."
Cook also claims that her husband and Barrino "recorded their illicit sexual activity."
As for whether Barrino knew Antwaun was married, Dickens said in his statement, "Fantasia believed Mr. Cook when he told her he was in a bad marriage and his heart was not in it. She believed him when he told her he and Mrs. Cook separated in the late summer of 2009. She believed Mr. Cook when he told her he lived elsewhere. He even took her there."
But Paula Cook claims that in October a family member spoke to Barrino directly and told her that Antwaun had a wife and two small children. In the complaint, Cook said Barrino responded that she "loved" Antwaun and "he was a grown man" who could "make his own decisions."
In June 2010, Antwaun separated from his wife. In her complaint, Paula Cook described a phone conversation with her husband in July, which Cook says Barrino interrupted, and allegedly told Cook, "He don't want you. ... Maybe the next time that you get a husband, you'll know how to keep him. ... That's why he is here with me."
