Provided you have the required mental capacity, a Power of Attorney for Property can be written at any time. Depending on how it is structured, it may take effect immediately, or it may only come into effect on a specific date or following a specific event (e.g. you become mentally incapacitated), as outlined in the document itself. If someone is to act on your behalf in respect of the CAAT Plan, we require a Power of Attorney for Property that is valid and operative.
