CLIENT: Trevor Gordon
COMPANY/FIRM: Real Estate Development & Investment
TESTIMONIAL: “After many years in dispute with an organisation with very deep pockets and utilising the so called expertise of no less than 5 different solicitors and 1 barrister there seemed to be no way of fighting against the tide. A colleague recommended Aejaz & OneLaw to me, once I had spoken with Aejaz and sent him the documents that the other legal professionals had been privy to, Aejaz somehow found an angle to approach and litigate the situation from. The battle commenced and the outcome assured. Great guy, he has a laid back approach and a never say die attitude. I highly recommend Aejaz Mussa and the team at OneLaw. Their approach might seem laid back but their bite is much worse than their bark!
