Word Document Meta Data Changed

Hello, and thank you to anyone reading this.

I have been a bit 'stitched up' by my employer, who, after challenging him on it has created a document in an attempt to retro-fit his reasons. I asked for the document but he has changed the date in the meta data to earlier that its real date of creation. It's a word document.

Is there any way for me to show that it was changed, or what the real creation date was?

Thanks in advance for any advice!
