Plot: What will happen in The Split season 3?

The third season will continue to follow the messy lives of the Defoe sisters – and in particular the separation of Hannah and Nathan.

In season two, the pair’s relationship broke down as Hannah’s affair with Christie was revealed. Ten months later, the two divorce lawyers have been respectfully negotiating their separation and seem to have reached an amicable agreement – until a shocking revelation changes everything and completely redraws the battle lines.

According to the BBC, creator Abi Morgan - who is also making her directorial debut for the third and final season - “is set to conclude proceedings with the most dramatic and heartbreaking series to date, as we watch a divorce lawyer confronted with her own divorce”.

Damien Molony, who reprises his role as Tyler Donaghue, exclusively revealed to BT.com that filming for season 3 finished in September 2021, with a 2022 potential release date.

Speaking in September to promote Brassic season 3, another of his projects, he told us: "We just wrapped up on The Split last week, actually. On my days off from Brassic I’ve been filming on the opposite side of the law, I guess! Working in a law firm and wearing beautiful suits.

"It will be out next year, I hope."

The BBC has since confirmed that the series will air in 2022. Keep checking this page for a confirmed release date.
