Is this a bit drastic? There would be a number of shares for UK? She would have shared in non-Irish companies, some would be UK companies with UK share registrars. Is there a way to simplify how shares will be sold in time? She would only hold shares in 10-12 companies, Irish, UK mostly.
Well based on my experience, I'm going for UK probate and then Jersey probate - the latter for Experian shares. The estate shares were all certificated which meant they could not be sold online. If you have US shares I'd definitely sell them soon, I hear the US authorities can be a nightmare to deal with re probate.
