Kourtney recently dumped the father of her three children after he was spotted canoodling with his ex in the France but Scott hopes her mother Kris can help them communicate to keep things civil.
A source told HollywoodLife: ''Scott thinks they really need a third party to mediate the next time they talk. For now he actually suggested Kris be there the next time he sees the kids to help keep things civil.''
The couple have children Mason, five, Penelope, three, and Reign, seven months, together.
Meanwhile, it was recently claimed that Scott isn't worried about being dropped from Kourtney and her family's reality TV series 'Keeping Up with the Kardashians'.
A source said: ''He's gotten away with so much for so long, he believes he's immune to anything they can throw at him. But the truth is, it's not going to take much for the Kardashians to ruin him completely.''
Kourtney and her family, including mother and manager Kris, are prepared to turn their backs on Scott for good unless he seeks treatment in rehab.
The insider said: ''They aren't messing around. If it weren't for the Kardashians, Scott would be a broke, drunk nobody.
''Everyone in the family feels completely betrayed by Scott. Kris truly looked at him like a son.''
The former restaurateur has spent three brief stints in rehab over the past year, but is still struggling to get his life back on track following the deaths of his parents, Bonnie and Jeffrey, within three months of each other in late 2013 and early 2014.
