Thanks for those insights.
Sorry if the information seems sparse, but I thought it straightforward. Contract is about to close, monies are about to be distributed, one hopes, and so, barring additional wrinkles, it's a matter of how long it takes for cheques to issue.
The 'whiff' referred to is the glacial progress to date, similar to MS's experience, though I think it is lack of urgency rather than sharp practice.
I'm sort of happy to see light at the end of the tunnel now, but I think I can be forgiven for being pessimistic!
PS: I'm dealing with an executor, not a solicitor.
