England. I have done 3 now. Mother and father when it was a big paper version and stepmother recently with online application.
Online was easy peasy. You can fill in a few questions, save the results and return later, pick up where you left off.
Not a complicated estate, bank accounts, savings and house. Only took 4 weeks and 1 week was taken up by applying for death certificates for the other 2 executors who had already passed away.
Successfully stated the case for zero inheritance tax on the estate valued at Β£480,000, accepted my explanation with double allowance (650k, deceased husband left total estate estate to wife) alternatively 325k + 175k as property left to direct descendants. This only took 24 hours from my explanation.
I wasn't about to pay Β£5k for something I could do myself.
