Kourtney Kardashian is reportedly hiring high profile divorce attorney Laura Wasser to get full custody of her three children post her split with long-time boyfriend Scott Disick.

The 36-year old reality TV star met Wasser, who has previously handled the divorce cases of her sisters Kim and Khloe Kardashian, Us Magazine reported.

Wasser's high profile clients includes Hollywood stars Angelina Jolie, Ryan Reynolds, Ashton Kutcher among others.

The Keeping Up With the Kardashian star reportedly wants to hire the top lawyer to secure her children's future after Disick was allegedly spotted drinking and doing drugs.

"Scott's friends don't think he'll challenge Kourtney," an inside source told the website. Another source accused the father-of-three that he "doesn't act like a dad at all when he's partying".

The couple have three children including five-year old Mason, Penelope (three), and seven-month-old Reign. All the three are currently living with Kardashian.

"She knows being with [Laura] is what's in their best interest. There's no turning back now and she is going full steam ahead with figuring out an agreement," a source close to the Kardashians told Us Magazine.

However, Hollywood Life has reported that the 32-year-old is planning to give custody of his children to their mother.

"Scott loves his kids but he also realizes he's in no condition to have custody of them. He told Kourtney that when he gets settled, he wants to discuss custody arrangements," a source told Hollywood Life.

The couple broke up earlier this month, after Disick was spotted getting cosy with his former girlfriend Chloe Bartoli in southern France.
