Nothing wrong with "any documents" per se.

Do you have any documents regarding this case?
Do any documents exist regarding this case?
Does any document exist regarding this case?

as examples.

Many thanks!!

Sie können die beide sagen, aber "any document" hat nicht oft gesagt.

z.B.
Is there any document in this office that is ready for approval?
Someone might say this after repeated attempts to find a document that is ready for approval with no luck.


Are there any documents in the office ready for approval?
This would be more commonly used, and you really can't go wrong with using this one.

You´re german is really terrible chichis. Where do you come from?

*gg*

@Chichi: I can read, so I think you're from the US.. What #4 means is that your answer should be:

"Sie können beides sagen, aber "any document" wird nicht oft verwendet."
oder:
"Du kannst beides sagen, aber "any document" wird nicht so oft benutzt."
;)

wow. Thanks for you honesty. I believe the AE stands for American English....

I believe those are the responses that prevent me from ever speaking German

;) That's what I believe, too..
Just thought it might help you to see what was wrong..
(I myself learn a lot by beeing corrected..)

Oh, no..I was to slow: I believe AE is "American English"..
I don't believe you should stop speaking/writing German! No way!!
