239. Acts done in pursuance of invalid power.

If an instrument has been registered1 as a lasting power of attorney2 but a lasting power of attorney was not created3 a donee4 who acts in purported exercise of the power does not incur any liability5 because of the non-existence of the power6 and any transaction between the donee and another person is, in favour of that person, as valid as if the power had been in existence7. This applies whether or not the registration has been cancelled at the time of the act or transaction in question
