Dad 84 with terminal illness and severe short-term cognitive memory issues (awaiting formal diagnosis) has signed documents presented to him by his young Thai wife. I have proof courtesy of a camera (legality of this has been researched and all above board as long as I don’t share with a third party) . Questioned Dad about documents and he doesn’t remember signing anything. Asked his Thai wife verbally and now three times in writing (for her to have translated) as suddenly her English is bad and now I have to send everything to a translator. I have Lasting Power of Attorney which was activated upon registering. If I ask Dad to ask her he forgets as she now leaves the house when I visit. Just to confirm Dad also wants to see the documents. Where do I go from here? Formal Solicitors letter? Would the Police take any action? Any ideas anyone?
