Small Claims
Cathy,
I'm sorry to hear of your situation, and I won't rehash the ground which has already been covered.
The limit for a small claims action in Scotland is £3000. If you have not already done so (and I suspect you will have) then I would recommend you speak to a solicitor regarding this matter as soon as possible. Most solicitors will normally have an initial meeting with you about any matter without charge, but not all so do check.
I hope that you get this resolved and that your daughter enjoys the remainder of her training and flying in the years beyond.
