If the basic requirements of the contract you signed are met and you are a qualified real estate agent, then the contract is valid. On the premise that you have invested up to 500,000 yuan in the contract and fully trust it, and fully meet the basic principles of trust protection, then they need to bear the liability for compensation. Even if they deny that signing the contract is not their company's intention, you have reason to trust them because of the official seal. This is the so-called apparent behavior, which can also be said to protect the interests of the relative person. Here, as the injured party, we don't need to take responsibility. They should pay the price.

Now your company is just preparing, so in whose name did you sign the contract? In fact, both the company to be established and the individual need to be the plaintiff, because your company was invented by you and does not exist. In this regard, if you are in the name of the company, you probably have to bear certain responsibilities, because you have violated the principle of good faith. Of course, you informed the other party, and the situation that the other party has agreed does not count.

Generally speaking, this case is not particularly complicated, but it involves a wide range and complicated content, and I am not completely clear about your statement. It is best to consult a law firm. Make your oral statement clear, and you don't have to pay for consulting a lawyer. As for whether to ask a lawyer to go to court, you can think it over carefully or ask a lawyer to coordinate. Sometimes private mediation can get more benefits and save a lot of trouble.

I hope I can help you.
