Application - Powers of Attorney given as security

A power of attorney may be given as security for an interest of the attorney. Where a power of attorney given as security is said to be ‘irrevocable’ (i.e. that it cannot be withdrawn by the person who is giving the power) it is made under section 4 of the Powers of Attorney Act 1971.

A Power of Attorney made under section 4 may be worded like this:

This power of attorney shall be irrevocable save with the consent of [the Donee] and is given by way of security to secure the performance of obligations owed by the Donor to the Donee under [name of agreement].

Other wording to the same effect could also be used.
