出卖人对其明知且实际会对房屋买卖合同产生足以动摇缔约意思或者缔约条件的房屋信息负有披露义务。在订立合同时,单纯沉默不构成欺诈,但若负有信息披露义务,并因沉默获得利益,则构成欺诈。买受人因欺诈而作出的错误意思表示,系可撤销的民事行为。合同撤销后,因欺诈造成买受人损失的,出卖人应承担民事赔偿责任。 The seller has the duty of disclosure to the house information which he knew and actually would have enough to shake off the meaning of the contract or the conditions of contracting the contract of sale of the house. When concluding a contract, simply silence does not constitute fraud, but if it has information disclosure obligations and benefits from silence, it constitutes fraud. The wrong meaning made by the buyer for fraud is a revocable civil act. After the contract is revoked, the buyer shall be liable for damages due to fraud. The seller shall bear civil liability for compensation.
