Technically, yes, and if you are passing the inheritance on to third parties it would certainly be advisable to cover yourself from any future claims. As Executor you would be personally liable.
However, if you are sole beneficiary as well, and there is no property or shares, check that their is no tax to be paid (or refunded) most Banks will pay out on a simple indemnity. Also if you take the invoice for the Funeral Expenses to the Bank for payment this will reduce the Estate even further.
Each Bank has it's own limit for this process, but most increased them last year.
