1, looking up from the other party's capital flow. For example, at a certain point in time when a house may be purchased, there is a large amount of money paid in the other party's account, which may be paid directly to the real estate company. For another example, an account of the other party has a fixed amount of capital expenditure every month, which may be a house loan or a water and electricity property management fee paid. If a person buys a house outside, as long as he pays close attention to his living habits, he can always find some clues. If they have been separated, or the other party is very cautious and sensitive, and there is no flaw, they can also investigate their whereabouts. After a period of analysis, you can draw a conclusion by investigating the suspicious properties they entered and exited. In practice, most of these situations are that one party knows the location where the other party is likely to buy real estate, such as a residential area, but does not know the location of the specific house. In this case, if you don't want to go to court for investigation and evidence collection through court channels, you can knock on the door from door to door or wait at the door. However, if the scale of the community is huge, there are hundreds of thousands of properties, or it is an unfinished community, this method will not work. What shall we do? No matter how big the community is, it is also managed by a property management company. So through the opening of the property, the other party's house can also be found out. 2. It is not very good for lawyers to investigate the investigation letter issued by the law firm now. The Lawyers Law does not give lawyers the right to investigate and collect evidence. If the investigated unit refuses to cooperate, lawyers are often at a loss. Therefore, lawyers are usually just holding letters of introduction or investigations issued by their own law firms, and they are often turned away and touched. This is not the incompetence of lawyers, but the problem of legal protection and social reality. 3. Property investigation is usually more useful than a lawyer holding an investigation letter if a friend of the property is flexible. The friend of the property is flexible and helps to check it. It is not illegal. After all, any unit or individual who knows the true situation of the case has the obligation to testify, but no one wants to be involved in the lawsuit, holding the concept that "more things are better than less things". 4. Court investigation If the property management company has no friends, the real estate company can't help it, and the relevant information masters have a negative attitude of "nothing to do, hanging high", they can apply to the court for an investigation order or apply to the court for a direct investigation. Generally speaking, the general real estate companies and property management companies will cooperate with the court's investigation order with the seal of the red house. After all, intentional neglect or non-cooperation may be suspected of "obstruction of litigation", and the court may impose a fine or judicial custody on the legal representative of the unit. Under such pressure, the relevant units will "know and do in one" and find out the specific house number of the other party in the community through the computer.
