Also I find a lot of nuances get lost with video calls but I am sure everyone loves working from home...
Why do you think it's because the solicitor wants to work from home. Dh is a solicitor and only worked from home full time during lockdown 1, as he had no choice. Even then he was still seeing some clients face to face where necessary, albeit outdoors, in hospices, etc.
Dh is a solicitor and does some video meetings. These are all at the request of clients, rather than them coming to the office.
Unless they are out of hours he does these at work. He hasn't worked from home for over a year.
They often work out cheaper. Solicitors are often paid by time, and the units of time are very short, often per 5/6 minutes. Less chit chat on video usually, and more straight to the point.
Documents can be send there and then, and viewed in screen and talked through - so no real loss there.
It's often more convenient for clients - they don't have to factor in travelling to and from the office, paying for parking/transport, etc. And to have a home visit from a solicitor would generally cost a lot more as you then need to be paying for the solicitors travel time/costs.
