In a CV, how do I list my status of a PhD if I completed the oral exam, but not awarded officialy?
I was advised by my supervisor that on completion of the viva, I would be informed immediately (orally) of the outcome, and from that point I would 'officially' hold the PhD qualification.

The corrections/amendments and the committee/Senate meetings are effectively rubber stamps, providing you actually submit the corrected version.

And so in your position I would state that I have achieved my PhD on the date of the viva within my CV.
