Can a healthcare proxy be revoked by a hospital?

Yes, a DPOA must be notarized. As well, the elder must present a VALID, IN DATE photo ID.

Pamstegma -- Thanks for mentioning "notarized" as a necessary condition for a healthcare proxy. I am 85. I recently started sorting through my legal documents and noticed that I hadn't updated the address of my healthcare proxy. I will prepare a new one.

Buffy, it was not the hospital who revoked it. It was a judge in surrogate's court. Sorry you are going through this. You need a good lawyer to enter a defense.

No it can not. However, when the patient is admitted, you must present your original, signed and notarized proxy document. So go get that.
