I see that there has been a similar post, but my facts differ in that we are at the end of the administration.
Executors are siblings, A and B.
All that remains is shares in one company to be transferred to B, but A has stopped corresponding. I don’t think they ever got on, so it is surprising that we have got this far.
We just needs the Stock Transfer form signing, but attempts to write to him have fallen on deaf ears.
Any practical (and cost effective) suggestions, as all money has been distributed form the estate.
I don’t believe there are any clever solutions other than the threat of legal proceedings. Obviously the action you personally can take depends on whether you are acting for one or both executors.
Subject to conflict issues, I would hope that a sternly worded threat of an application, and consequential costs, might move him along. Depending on value, such threat could also include the possible claim for damages that would follow if the market dropped while distribution was delayed.
