Soden, a contractor, made a contract to build a house for Clevert. The sales contract stated that "if either party defaults in the performance of this contract," that party would be liable to the other for attorneys' fees incurred in suing the defaulter. Soden was 61 days late in completing the contract, and some of the work was defective. In a suit by the buyer against the contractor, the contractor claimed that he was not liable for the buyer's attorneys' fees because he had made only a defective performance and because "default" in the phrase quoted meant "nonperformance of the contract." Was the contractor liable for the attorneys' fees?
