"Family Law" centers around Abigail Bianchi, a high-paid personal injury lawyer who's good at blaming others -- particularly when it comes to her own problems. After Abby's husband kicks her out of the family home because of her drinking, she goes on a bender, shows up drunk in court. The law society's punishment is swift. She's suspended, fined, and can only practice law again if she finds a senior lawyer who is willing to take her on and mentor her for a one year probationary period. Only one man is willing to take that risk: Harry Svensson, who runs the top family law practice in the city. He also happens to be Abby's estranged father, who left Abby and her complicated mother for his secretary when Abby was seven. Thus begins the odd dynamic at Abigail's new workplace. Abby has to try to put her shambles of a life back on track, all while working under the thumb of the man she's spent a lifetime resenting.

Abigail and Daniel represent Ira, who wants his wife Helen moved from a care home that he claims is worsening her Alzheimer's; because his daughter doesn't want Helen moved and holds power of attorney, Ira must challenge her in court.

The lawyers are bewildered when a young couple begs them to reverse an adoption after learning about the baby's serious health issues; Abigail determines that the father is driving the decision, and convinces the mother to fight to keep the baby.

Abigail and Daniel represent a soon-to-be-starving-again artist who was once the third member of a polyamorous relationship; Daniel regrets dumping Danielle; after Abby gets doxxed, Frank and the kids stay with her at her mother's place.

Abigail gets in over her head when she agrees to defend a friend who is anti-vaccine; Daniel is bitter over Harry's rejection of his partnership proposal; Nico gets suspended for forgery, forcing Abby and Frank to reconsider their parenting plan.
