Using a power of attorney
Your attorney can only act on your behalf in the way you have granted.
If they use the power in a way you haven’t given them permission to, they can be liable for compensation if you suffer any losses.
The powers can only be transferred to a third person if they have been given power of delegation.
A power of attorney can be used overseas when it is allowed by that country.
You should contact that country’s consulate, high commission or embassy for more information.
