When we decided we needed the help of a solicitor, as we were looking at a tribunal against a decision not to assess, we went to various law firms. Their costs were very similar. I'm not surprised by the figures quoted above.
However, while most law firms we contacted would only have a very junior person talk to you about your case before the timers started and bills came in, and some didn't even call back after multiple messages, SEN legal had their most senior lawyer call us and she gave us an hour of her time to go through all the details. We didn't have to pay a penny for this. After hearing what they had to say, they seemed like the best option. Admittedly they're not cheap, but to date things have gone as predicted and we've had no nasty surprises financially (that nasty surprise happened before we signed any agreement with them or any other lawyer).
The bills do add up, and it isn't fair. Much of this is down to the shocking behaviour of the local authorities, who do not follow the SEN Code of Practice, are not offering the support that these children are legally entitled to, are so under staffed they they're shoddy to say the least. And, what is this down to... Well our current government isn't helping with it's cuts that simply seem to target the most vulnerable.
They system is totally wrong. It is completely unfair that only those with resources are able to pay for legal support that all of us in this boat are entitled to. Legal aid should be available, and tribunals should be able to award costs. The whole system sucks.
