Ready For Battle! Scott Disick Retains Attorney To 'Fight' Ex Kourtney Kardashian 'For His Money' -- How Much Is He Going After?

It has been almost one month since Kourtney Kardashian finally kicked out Scott Disick. And though the father of three has spent much of that time partying around the world, RadarOnline.com has learned he is finally ready to face up to the reality of the split -- and fight his ex in court!

The mother of Mason, 5, Penelope, 3 and 7 month old son, Reign obtained attorney Laura Wasser to fight for her fortune and sole custody of the children weeks ago, and now, RadarOnline.com has learned that Disick has also lawyered up as well.

"Scott is ready to fight her for what he believes is half his," a well-connected Keeping up with the Kardashians family insider says. "And he may be right."

"Kourtney knows that Scott carried the storyline for years and he is now using this as ammo with her," says the source.

"He has told her that if he wasn't drunk than they wouldn't have kept everyone's attention for so long."

As RadarOnline.com previously reported, Disick's womanizing and alcoholic rages were a prominent topic on both KUWTK and its spin-off, Kourtney & Khloe Take The Hampton.

According to the source, "Kourtney knows that Scott does have a point."

Although he has not filed any action just yet, the family friend tells RadarOnline.com, "They both want this to be settled out of court because there is no need to go into a messy back-and-forth."

"They are both incredibly rich already and will continue to get rich together or alone," says the source.

"Scott also wants open visitation with his kids and he knows that will be based on his ability to stay sober, as the court definitely takes that into consideration."
