Reese's Estranged Hubby Wants ...

Ryan Phillippe has fired his shot off the bow in his divorce with Reese Witherspoon.

TMZ has obtained court documents, filed this week in Los Angeles County Superior Court. Phillippe wants to make a clean break from the marriage. He is not asking for spousal or child support. All he wants is joint custody of the two kids.

Witherspoon filed divorce papers last November, citing irreconcilable difference. She asked for joint custody, and also asked the judge to block any attempt on Phillippe's part to get spousal support. Reese also wanted "exclusive use of the family residence."

TMZ first reported that the former couple did not sign a pre-nup, which means their assets acquired during the marriage will be divided even-steven.
