Lost late DH's will.

You would have to pay a small amount, but once probate has been granted, or a short while later, wills are public documents and you can obtain a copy - in fact I believe you can obtain a copy of anybody's will, as long as you have their details.
Google will tell you where to apply.

If the Will was drawn up by a solicitor they may have a copy on file, although obviously it would not be a signed copy. If the Will is not being contested then as you have Probate there shouldn't be a problem. I believe a Will can only be contested up to 6 months after death.

Thank you so much. I was merrily shredding away this afternoon, and as I have just made a new will thought I'd get rid of my old one, but I must have pulled out DH's by mistake and just didn't notice. I have googled and it's £10 for a copy on the government website, which I think I might do. I would like to have a copy of it.

Our wills are at the solicitors? My husband died 2 and a half years ago, will they still have it?

No, my new solicitor requested the original when DH died and passed it on to me once DH's estate was dealt with. They may well have a digital copy, though. I just can't believe I've been so careless!
