If I needed will advice rather than just writing my own, I would go to a “proper” solicitor who is regulated rather than to a will writer who is not. You don’t have to name them, or their company as executors, in fact the bloke (solicitor) who did my will advised me not to! If you want a funeral plan then most of the national funeral director type companies will sell you one. You say what you want, they give you a price, you pay for it, end of story, nothing more for the family to pay unless they want to add anything. As for putting the house in trust, well that wants thinking about very seriously....and not advice taken from a firm with a vested interest in doing it for you!
