辽宁读者李鹏问:我是一家私营建筑公司的负责人。去年初,我与某单位订了一份建筑工程承包合同,合同约定,由发包方按预算支付50%工程款,其他由我垫付,工程竣工后清算。今年7月工程完工,但发包方未按合同约定支付下欠的350万元工程款。请问,我有权将所承建竣工的不动产用来抵债吗 Li Peng, Liaoning Reader Q: I am the head of a private construction company. At the beginning of last year, I signed a construction contract with a certain unit. The contract stipulates that the contractor will pay 50% of the project cost according to the budget and the others will be paid by me. After completion, the project will be liquidated. In July this year, the project was completed, but the Employer did not pay the contract to pay the project under the 3.5 million yuan. Excuse me, I have the right to use the completed completed real estate to cover the debt
