As mentioned previously you can do this yourself if the estate is a simple one.
The probate form is simple to fill in and there are guidance notes to help.
You send the completed form,original death certificate and original will to the probate office of your choice with a fee of �96 pounds. Plus �1 for each copy of the letters of probate that you will require to send to all banks which hold . the deceased 's cash.
You will then have to attend
the office you have chosen for an interview with a legal. representative of the office.
This is not scary, they will check your ID(the guidance notes tell you what to take), they will check the form with you and go trhough the will to make sure you understand about any bequests which need to be made and that's it.
About 10 days later you will get the copies you have paid for and you can begin to sort out the will.
You do not have to be brain of Britain to do this process if the will is straight forward.But if it complicated with shares and properties then stick with the solicitor.
Just remember to take copies of everything you send, you will not get the will back ,it becomes an item of public record.
For general enquiries there is a phone no.0845 3020900
this is the probate help line.
Good luck.
