"Is there something in the will that we were meant to know and this has been kept from us."
And this all happened a few years ago? Why have you waited?
Ask. Your brother- altho' how you know he is the executor if you don't know anything else is a bit of a mystery.
If you get nowhere there, ask the solicitor if he is dealing with your late father's estate. if he is, he does not have to deal with you, the executor is his client , not you if you are not a beneficiary.
If you are a beneficiary, and he is dealing with the estate, he should be able to tell you something.
Go and see a separate solicitor yourself. If you give them the full story e.g. date of death, list of assets etc.,etc, they could make some preliminary enquiries by way of property searches to see if there are any property assets in your fathers name or that have been transferred.
"am I dealing with a corrupt family solicitor"
That's a big leap - your problem is with your family ( all of you, not just your so-called devious brother).
