1. Can you better explain the situation. When did your sister not have the mental capacity to understand the Power of Attorney. Is it today, if you were to get it registered, or was it when it was created? Was there a psychiatrist involved in the creation of the Power of Attorney or other medical practitioner who attested to her legal capacity at the time of the making of the Power of ATtorney?
2. I regret to say that a Lasting Power of Attorney is not valid unless there was a medical practitioner who signed off on your sister being able to understand what she was doing. Having your "sister's social work" is not sufficient. Was there a medical practitioner involved? If not, then you need to get a fresh Lasting power of attorney made up today, this time involving both a solicitor and a medical practitioner.
