having a copy of the notorized form and the original certified mail reciept makes you compliant, with those in hand you are good to go
An application with proof of mailing is actually no longer sufficient to prove eligibility of patients. In the past, a patient was not technically legal until 35 days from proof of mailing providing that the CDPHE had not denied the patient. Here's the link to that decision:

These days, the CDPHE is sending red cards in 10 days to 2 weeks. So given this, the patients do not arrive at the 35 day mark without either receiving their card or being rejected.
So the reality is today, without an actual red card in hand, a patient is probably not legal at least for the criminal exception granted by the constitution. However with as little as a doctor's rec, the patient should still qualify for an affirmative defense. But that only has potential to work in a court room, and you don't want to be there.
With what I have indicated above, here is what I believe you would need to hold onto to be a compliant caregiver for your patient:
1] Photo Copy of patient's red card
2] Photo Copy of patient's Colorado Photo ID
3] Photo Copy of patient's Notarized Change of Caregiver form with your name on it
4] Signed agreement between patient and caregiver indicating terms of arrangement.[and that they will notify you of a change]
5] Technically, you can not show patients medical information [red card] to anybody[police] without a signed HIPPA Release form from the patient, but that's another whole can of worms...
Understand that this is just advice from some jackhole on the internets and not real live legal advice. However, I have shelled a bazillion dollars to lawyers and have at least a minimal clue
Hope this helps... Keep in mind that this is subject to change with CDPHE rules requiring the standard of care outside of the provision of MMJ that would qualify you as a "Caregiver"
