It is unfortunate that you lost your lawsuit where the agreement that you sued upon has an attorneys fee clause and where your landlord hired a lawyer to defend him in it.In order to determine what are reasonable attorneys fees in every circumstance where such attorneys fees are an issue, you need to see complete copies of the billings by the attorney representing the prevailing party. In your case, you need to see what actual fees your landlord paid his or her attorney for the defense, the amount of fees charged and what legal work was actually done.In some states courts have held that attorneys fees of $20,000 to deal with a small claim of $2,500 which was at issue were clearly excessive given the relationship of the $20,000 to the $2,500 claimed.Good luck.
