won’t need the solicitor again.
There are lots of ways to be the executor.
One way is to register the death, organise the funeral and ask a solicitor to obtain probate and, in consultants in with you, to distribute the estate.
Another is to do it all yourself.
You can also do some yourself, and then use a solicitor to do specific parts, such as to sell the house.
You can also, when you actually see the will, decide to renounce the role of executor. It's fair enough to renounce if there are onerous or ridiculous conditions attached.
If you are the only family left and there is a will, it ought to be very simple. Wonder what the solicitor meant? No ideal to raise worries if they are not in a position to tell you any details.
Executing a will is an unselfish service you can provide to someone who won't be there to appreciate it. Don't underestimate the responsibility but equally it's a shame to have a solicitor write the letters to find out the value of the estate. That's just admin, easy to do yourself.
If I had one wish for the estates I have done, and am in line to do, it would be for there to be a simple list of all the valuables. Eg the sort code and account number of any bank accounts, contact details for any private pensions, share holdings, investments. It makes life so much easier to be working from a list rather than hunting down anything and worrying that you might have missed something.
All the best.
