If a law firm has gone out of business, the likelihood is that it has been taken over by a ‘succession firm’ and your Will has transferred over to the new firm. If it is not immediately apparent which firm has taken over, you can contact the Law Society who should be able to provide you with this information. You will then need to contact the new firm to confirm that they have your Will.
I made a Will with a solicitor years ago and they’ve gone bust- how do I find my Will?
