Hi Saranjeet, thanks for your reply. Contacting the AOP was the first thing I did. I spoke to the legal adviser. She was sent a copy of the contract and commented that she had never seen anything like it; the exposure to unlimited costs being most unusual. Whilst being sympathetic she was unable to help in anyway as it was ultimately my choice whether or not to work under such a contract. The AOP insurers were my next port of call. But alas, no success so far in obtaining cover because of the potential of unlimited exposure to 3rd party costs.
