We used a resolution accredited firm of solicitors. It really meant nothing because the partner we used promised the earth and delivered nothing. He was all tough fighting words, but no action. A dead give away and mistake on our part was the fact that he slagged off any other solicitors involved in the case, using bad language to do so. I think he thought it gave him some street cred, but in reality he was a total tosser.
Years later I see people taken in by his fighting talk and yes, he still talks the talk, but unfortunately you have to remember you are charged an extortionate hourly rate to listen to it.
We ended up using a solicitor from out of the area who, whilst I would not describe as great, got our case and was a calming and pleasant influence during a difficult, sensitive time. I would also add, that when employing the first solicitor, I had to draft my own statements whereas the out of town lawyer grasped the case straightaway and this alone reduced stress.
I required assistance from our MP during the case and saw his assistant whose immediate grasp of our family case was far superior to that of the first solicitor.
So, you have got a good vote and a bad one. Go with your instincts.
