夫妻双方就房产分割达成的离婚协议应视为一种以离婚为目的的复合协议,在离婚登记之前该协议不生效,经婚姻登记机关登记离婚后协议生效。 The divorce agreement reached by the couple on the division of the property should be considered as a composite agreement for the purpose of divorce. The agreement does not take effect until the divorce registration is completed and the agreement takes effect upon registration of the divorce by the marriage registration authority.
