It might be a good idea to draw up some paperwork!

Travis Scott, Scott Disick, and Tristan Thompson all have no formal custody agreements in writing for the children that they share - or are soon to be sharing - with the Kardashian-Jenner girls, TMZ reports. That means that the rapper, the reality star, and the NBA player are relying on their baby mamas to do the right thing in the event of soured relationship, which is risky to say the least.

Kourt and The Lord split a while ago, but they share custody of their three children. It's never really been an issue, except for when he was going off the deep on a wild alcohol bender, and the 38-year-old withheld visits from their brood until he sobered up.

As for financials, we'd think the K clan would want to protect their fortunes! Specifically Kylie, who was just crowned the richest member of the family thanks to her $386 million LipKit business. It's projected that it will turn into a billion dollar empire by 2022, too!

In case you were wondering - Travis' net worth is around $8 million, Scott's is $12 million, and Tristan's is $9 million.
