I have POA over my grandmother but currently my mother has my grandmother in her care. She is refusing to put my grandmother into a pre arranged respite and care provision following the death of my Grandfather. She has also managed to influence my Grandmother to state she wants to live with my mother. When well my Grandmother and Grandfather (recently deceased) assigned me as POA because my mother is manipulative and ultimately after my nan's money. What should I do next, the social worker seems a little feeble. My nan has dementia and failing physical health. When well she had stated that she never wanted to live with my mum.
