Don't know the answer but I'd guess you would want the other name on the title to go with you to the DMV to transfer ownership completely OR perhaps a signed letter (maybe w/ power of attorney or notarized) to get it done solo.

I've heard folks have had reasonably good luck sending in a question to the DMV and getting a response in a timely manner. I'd be detailed in your question to avoid a generic/unhelpful response.
