Bent fork?

I recently crashed on my Cube AMS 125, which resulted in a bent frame 
Now I want to buy a new frame, and equip it with my current fork (rock shox revelation u-turn 2010) but I'm afraid that the fork is bent too. The bike turns left by it self when I ride it which may be the cause of a bent frame or/and a bent fork I reckon. I'm wondering if anyone can tell me how to check if the fork is bent?

Cube do sell some frames on their own, contact your Cube Dealer, you may get one at a reduced price as I think they have a crash replacement scheme.
Any pics of the damaged parts?
Thanks for the correction of my English by the way
I can't figure out how to add pics in a post, but I do have some
Still need to know about the fork though.
