The Split is a critically acclaimed British legal drama created by Abi Morgan that explores the high-stakes world of London’s divorce circuit through the lens of the Defoe family, a powerhouse of female lawyers. As of March 2026, the franchise has expanded significantly following the conclusion of the original three-season run in 2022. The most recent major milestone was the release of The Split: Barcelona in late 2024, a two-part special that saw Nicola Walker return as Hannah Defoe for a dramatic destination wedding in Catalonia. Furthermore, fans are currently awaiting the premiere of the first official spin-off series, The Split Up, which wrapped filming in January 2026. This new six-part series shifts the focus to Manchester and the Kishan family, led by Ritu Arya and Sanjeev Bhaskar, effectively turning The Split into a broader “Shared Legal Universe” that examines the complexities of modern marriage, succession, and South Asian legal dynasties.
The Defoe Dynasty: Core Cast and Characters
At its heart, The Split is a character study of the three Defoe sisters and their formidable mother, Ruth.
Hannah Defoe (Nicola Walker)
Hannah is the moral and emotional center of the series. A top-tier divorce lawyer, her decision to leave the family firm for rival Noble & Hale in Season 1 set off a chain reaction of professional and personal betrayals. In 2026, her character remains an icon of “working-woman realism,” particularly her complex decision-making regarding her affair with Christie Carmichael.
Nina and Rose Defoe
Nina (Annabel Scholey) and Rose (Fiona Button) provide the emotional counterpoints to Hannah’s stoicism. Nina’s struggles with alcoholism and kleptomania, and Rose’s journey through grief and surrogacy, represent the “human cost” of the high-pressure Defoe environment. Their arcs concluded with a sense of cautious optimism at the end of the 2024 special.
The 2024 Special: The Split Barcelona
Two years after the main series ended, Abi Morgan surprised fans with a “destination” chapter that redefined the show’s scope.
A Catalan Wedding Backdrop
Released in December 2024, the special gathered the original cast for a wedding at a magnificent vineyard in Catalonia. The plot centered on the wedding of Hannah’s daughter, Liv, while forcing Hannah and her ex-husband Nathan (Stephen Mangan) to confront the “ghosts” of their failed marriage in a neutral territory.
New Faces in 2024
The special introduced Toby Stephens as Archie Moore, a charming yet competitive family lawyer who served as a new romantic interest and professional rival for Hannah. This addition was praised by critics for injecting new energy into the established character dynamics.
The Split Up: The 2026 Spin-off
The franchise’s future lies in Manchester with the launch of The Split Up, a spiritual successor that maintains the original’s DNA while exploring new cultural territory.
The Kishan Family Dynamics
Set in Manchester’s “high-net-worth” divorce circuit, the series centers on Kishan Law, a British-South Asian family firm. Ritu Arya stars as Aria Kishan, a rising star fighting to take the mantle from her father, Dhruv (Sanjeev Bhaskar), amidst a cloud of family secrets and succession battles.
Production and Status
Filming for the first series of The Split Up wrapped in January 2026. As of March 2026, the series is in post-production, with first-look images recently released by the BBC. It is expected to headline the BBC’s Autumn 2026 drama slate.
Technical Themes: Law and Ethics
One of the reasons The Split resonates with professionals is its realistic depiction of the divorce process.
“No-Fault” Divorce: The series accurately tracks the real-world shift in UK law toward no-fault divorce, reflecting the evolving landscape of matrimonial litigation.
Mediation vs. Litigation: A recurring theme is the ethical struggle between “winning” for a client and preserving the family unit, a conflict Hannah often faces.
Client Confidentiality: The show frequently uses “case-of-the-week” subplots to mirror the personal dramas of the Defoe family, creating a thematic bridge between the professional and personal.
