Casey Affleck's divorce has been rubbed stamped.

The 'Manchester By The Sea's star's ex-wife Summer Phoenix filed for divorce back in August and it has now been revealed that it has all been finalised.

The pair - who were married for nearly a decade - came to a financial agreement as well as a decision on the custody of their children, Indiana, 13, and Atticus, nine, TMZ reports.

Summer officially filed for divorce back in August but the pair had been split since November 2015, making the announcement they were to go their separate ways back in March 2016.

When Summer filed, she cited ''irreconcilable differences'' but asked for joint legal and physical custody of their children and also requested spousal support.

When the pair split, they issued a joint statement to insist they had ''amicably'' gone their separate ways.

The spokesperson confirmed: ''Casey and Summer have amicably separated. They remain very close friends.''

Whilst a source added at the time: ''She was having a lot of trust issues. They went to couples counselling but they just couldn't recover.''

Casey had previously admitted he is unsure whether the breakdown of his marriage - which was coming to an end during filming for 'Manchester By the Sea' - had any impact on his performance in the hit movie.

He shared: ''I don't know. It sounds crazy, I acknowledge that, but your body doesn't really know the difference between experiencing something for real and convincing yourself you're experiencing something. Are you in a dark place in your personal life and it helps make the movie? Or do you put yourself in that place in order to make the movie?''
