Hi Louise yes this is worrying as you say you could get all through the process on one Poa this is what I know she wants and presumably if the solicitor agrees they won’t involve me. Good idea about the bank account@Grancan1313 I sold my Mum's house a couple of months ago. Like you and your step mother I hold joint & several financial power of attorney, with my sister. I produced the original power of attorney letter to the solicitor and they advised that they were happy to liaise with me regarding the sale and did not require my sister to be involved, although I was keeping her informed at every stage. I was able to go through the entire sale process, including signing/exchange of contracts, without my sister being involved.
If you are concerned that your father's share of the sale may not be paid into a separate account, as financial attorney there is nothing to stop you from informing your stepmother that you will be opening up an account in your father's name for receipt of his share of the funds, opening the account and then providing the account details to the solicitor. This will give your step mother the opportunity to let you know whether a separate account has already been set up or not for your father. As joint attorney you are as responsible for ensuring that your father's finances are managed in his best interest as his wife is so you should be proactive about the situation.
