Name change problem!

Thank you Sir, I will do all the necessary docomentation before i change my name...but my question was, will it effect my ongoing recruitment process...As i have registered for my recuruitment exam in my current name, What if, I change it just before the examination or before interview(already registered with present name)

Will it create any problem in my selection?? (even if I show them all the orignal docoments regarding name change)

Please answer...
