Just to say there is a difference between validating and agreeing. and sometimes it might not be great to tell them how they feel.

for example you could say
'I know you feel like i'm dragging my feet so we should get lawyers involved'

or you could say

'I understand your concerned by the progress we have made in resolving these issues and so if you feel it is right that we should get lawyers involved then i'm willing to support that'

there is probably better wording but i hope that makes sense
