I worked in a place to know that some solicitors are thick as pig s****,
I worked recovering costs and taking legal actions from third parties. There are strict limits on what are reasonable costs to claim from 3rd parties.
What is treated very strictly by a court is "Mitigation of costs" if one side has not mitigated their costs then it gets thrown out.
They can't just go round making costs up, ask them to break down the 2k costs because your solicitor wants to see it, and if it isn't justified then you will counter claim for the costs of your solicitor.
Maybe it needs rewording then my advice, "ask them why they haven't mitigated their losses by going direct to Nominet"
Ask them if they have previously had disputes in this country and why they continue to not take the cheapest path to settlement?
Might be wise to forget the pee in the wind stuff at this point
