Power of attorney

^ This should not be a problem because you can still carry out his original wishes as the money is yours to do as you wish.^

I think I'm right in saying that, if you do this, it might mean the people you give it to end up paying Inheritance Tax as it wasn't given directly from the Will. May be worth checking that!

Carry out ‘his’ original wishes, that should have read

If you do not male new Wills everything in his Estate will go to you. This should not be a problem because you can still carry out in original wishes as the money is yours to do as you wish. Will making itself is not expensive just a few hundred pounds. I would contact AGEUK who have excellent service

I am so sorry your partner is terminally ill. My very best wishes on getting married.

Wills are invalidated by marriage.
It also costs to change a name on a Power of Attorney, which I have looked into myself because one of my attorneys has reverted to her maiden name, and my solicitor says it will delay things if the time comes, and she then needs to dig out all her paperwork to prove who she was.

Nanny I'm so sorry that your partner is terminally ill.

You can definitely make changes (edit) a lasting Power of Attorney and I'm almost certain that includes a name change. You could write to them or look on the website.

I'm not sure about your Will but if you have already got one, it shouldn't cost the same large amount again just to change the name.

Our Wills are lodged with an attorney - I presume if it cost you a lot of money yours was also done via attorneys. They should be able to tell you.

Good wishes on getting married, albeit in very sad circumstances.

No but I believe you will need new wills after a marriage.
Do take advice.

The best thing to do is ask a solicitor.
