Myself and my partner are not married but have been together for decades. We have a joint bank account we pay bills out of, but all other bank accounts are in my name only, apart from his personal account. We see the savings as joint money. I'm better than him at organising money so have various isas, and savings accounts. Now intrest rates are higher, I will be liable to pay tax as I will go over my personal allowance. I'd like to transfer some of the savings into his name so he can use his tax allowance. Can he open his own savings accounts so I can transfer money over to him? Or can I make my savings accounts joint ones? I'm not sure if the legal requirements when transferring money. Thanks
