Uncles Estate - late ex wife's sister making claim

This arrangement sounds very amicable and civilised…..
 
Same here, got a judicial separation in 2014, and finally now divorced woo hoo, was worth the wait. My ex was engaged before we even divorced, so I walked away a free woman, he walked straight into the next marriage
 
I understand, but the key thing is that he was still married and the wife, albeit estranged and seemingly separated in some shape or form, seems to have still had a statutory entitlement to claim on his estate which her sister now seems to be pursuing. I presume that you've spoken to a solicitor about this?
 
We have contacted every solicitor he ever dealt with, the original family law solicitor, the solicitor my parents used, our grandparents probate solicitor and no one holds files from 1978….even tried the national archives….it’s in the hands of our uncles current solicitor, and we are confident that he will gather what he can, to build a case against their claim, he was a stranger to them, a charity would be more deserving of his money than them, but the law is the law, so we can’t do a lot to stop them
 
We do have a good solicitor working on it, one our uncle used for the later stages of his life. Fingers crossed….
 
How much money is actually involved here?

Theres a good chance agreeing a settlement will be cheaper than legal fees.

Never forget the lesson of Jarndyce vs. Jarndyce.
