The power couple stand to win millions against the man after they were given the go-ahead with the case on Tuesday. It was decided that the case did not violate the free speech rights of the YouTube defendant, Chad Hurley.
Kim and Kanye will face Chad in court on Nov. 17.
The technical entrepreneur filmed the moment Kanye popped the question, later posting the two-and-a-half minute video on his video-sharing website MixBit.
Despite signing a confidentiality agreement, Chad claims that he wasn't informed of not being allowed to film or distribute the footage which Kanye did allow to be filmed by E! Entertainment. The network broadcasts the Kardashians' reality TV show Keeping Up With the Kardashians.
But Superior Court Judge Ruth Ann Kwan agreed that the key word 'CONFIDENTIALTY' could be read clearly on the document that he had signed.

Kanye hired out the AT&T Park stadium in San Francisco, California to pop the question to Kim in front of her family and friends on her 33rd birthday.
He then presented the mother of his daughter North West with a 15-carat diamond ring by celebrity jeweller Lorraine Schwartz.
Jubilant celebrations naturally ensued, with guests and the newly-engaged couple toasting the joyous occasion – all of which was caught on camera.
