LPA - authority from donor

Bit of a practical question here. Attorney is appointed unrestricted under a registered LPA.

The LPA (this is one of the older versions) says that the Attorneys can only act with the Donor’s consent.

Scenario is this: Attorneys all instruct Solicitors to sell Donor’s property. Donor is elderly and frail and so unable to be contacted. What lengths do the Solicitors need to go to to satisfy themselves that they are acting with the Donor’s consent? Or is the consent more an obligation on the Attorney (in the same way that we don’t need to weigh up every decision and decide if it is in the Donor’s best interests for example).

We encourage LPAs on the basis that their Attorney can help them when they are unable to (both before and after capacity is lost) so it seems counter-intuitive to say that we need actual consent each and every time the Attorneys do something on their behalf?

If you have a conveyancing department - what is your advice to them? Can they act under a registered LPA without needing specific consent from the Donor?
