Ben Affleck and ex-Jennifer Garner did their best in rearing their children

Ben Affleck and Jennifer Garner has ended their decade-long marriage last year but have remained friends ever since. Unlike other failed marriages, the two have since lived in the same house and have remained active in their three children's lives as co-parents.

In the set of his new film "The Accountant" in Los Angeles, the "Batman" actor narrated how they make co-parenting work. Mail Online reported that they simply try to do their best. Despite his very busy filming schedules, he makes sure that he keeps memories of home with him. He said that he hangs up their kids' art inside his trailer. He and Jennifer share everything when it comes to co-parenting but he confesses that he is not too good with homework. The 44-year old actor said that his trailer serves as a reminder of home where he hangs the latest artwork from school.  

CNN recalled that it was shortly after the couple's 10^th anniversary when they announced that they were getting a divorce in a joint settlement. Back then, Jennifer and Ben said that they share love and friendship and a commitment to co-parent their kids. And it looks like that till this day, the two kept to that commitment.

When Ben had to go overseas for the filming of "Justice League" Jennifer took their kids to Europe to be with their father. She also had to look after their children while Ben was promoting in New York for "The Accountant."

Jennifer was also vocal about their living arrangements as co-parents. She said in an interview at the Today Show that she and Ben had no choice but to be in good terms with each other. She also added that they are a "modern family" and that they are doing really well.

"The Accountant" will premiere on October 14 in the US. Ben Affleck plays a mathematics savant Christian Wolff who works as an accountant for dangerous criminal groups. Also starring are J.K. Simmons and Anna Kendrick.
