For those of you who haven't watched the must-see series, the intense BBC One drama follows the formidable Defoe sisters who all work in the tangled world of family law.
The third series (which is billed to the The Split's last) now sees Hannah (Nicola Walker) forced to face her own break-up, after she betrayed husband Nathan (Stephen Mangan).
Watch a trailer for the previous seasons here.
News of a third series was confirmed by the BBC earlier this year, with the channel also confirming the cast had been reunited as filming now commenced.
The announcement also revealed another bombshell - the suave and sexy Christie (Barry Atsma), known for his womanising ways and bountiful charm, is back, despite having been the catalyst for Hannah and Nathan's own split.
Also joining the cast for the last season is Sherlock star Lara Pulver, who will play savvy child psychologist Kate. Her arrival is expected to add a layer of complexity into the story, particularly as Hannah and Nathan's divorce proceedings are expected to get explosive.
Speaking about the final series of The Split, series writer Abi Morgan explained: "For every writer there are characters that stay with them, long after a show is over. Hannah Defoe and her family are just that, and it's been a welcome balm after a difficult year globally, to reunite this brilliant cast.
"The Split has been building to this exhilarating final act for the Defoes as they navigate their way through the marital make up and break up, both personally and professionally, at Noble, Hale And Defoe.
"They say you can't have new beginnings without endings, and I want to say a big thank you to the BBC and AMC, and the fans who have kept running by our side."
If you feel like you need a refresh of events from the past two series, The Split is available on BBC iPlayer before the third season is released later this year.
We can't wait...
