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 “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”.

The Split season 3 release date

As of February 2021, casting for season three continues and filming is still due to begin. While coronavirus restrictions are ongoing, 2022 seems a likely time for the new series to air – though if the turnaround is quick, late 2021 is also possible.

Will there be a season 4 of The Split?

It doesn’t look like it. The BBC said the latest season would be the “third and final series”. And creator and writer Abi Morgan previously said the show “has always been conceived as three”.
