编辑同志: 2002年10月8日,我的一位亲戚和一家开发商签订了一份商品房买卖合同。当时约定的交付使用时间是2003年6月8日,否则,开发商要支付房价10%的违约金。但到了交付之日,开发商只把钥匙交给我的亲戚,没有把房产证书等一并交来。于是发生了纠纷。开发商认为“房屋交付使用”就是“交钥匙”, 他们没有违约;而我的亲戚则认为,“房屋交付使用”不仅是领了房屋钥匙,还应同时办理交付房屋的所有权证书,否则就是违约,应支付违约金。请问,他们谁说的对呢? 读者余心乐 Editor’s Comrade: On October 8, 2002, one of my relatives and a developer signed a sales and purchase contract. At that time, the agreed delivery time was June 8, 2003, otherwise, the developer pays a liquidated damages of 10%. But by the date of delivery, the developer handed over the keys only to my relatives and did not hand over the certificate of property. So there was a dispute. The developers think the “delivery of housing” is “turnkey”, they did not breach of contract; and my relatives believe that “delivery of housing” is not only the key to the house, but also at the same time to deliver the certificate of ownership of the housing, otherwise it is a breach of contract , Should pay liquidated damages. Excuse me, who is right?
