To sum up, there are three ways to coordinate A to handle the transfer formalities with you as soon as possible: 1. A will come back in person to handle the transfer formalities with you. It's not complicated. You can consult the housing management department in advance and prepare relevant materials. A only needs to be present, and it will be completed in half a day. 2. As A said, go to the notary office to handle the entrustment, and entrust a third party to handle it. What you said in your question is that it should be handled at the location of the real estate because the notary office also has restrictions on the scope of acceptance, but the scope of acceptance of the notary office is not 100% unbreakable, so you can continue to do your work. In addition, the notary office is the district notary office of each district, the municipal notary office of each city and the provincial notary office of each province. I suggest all three notary offices ask. If the notary office in the area where A is located really refuses to handle it, it is not necessary to handle it at the location of the real estate, because since A can go to the location of the real estate, he can directly handle the transfer to the housing management department where the real estate is located, and does not need to entrust him to handle the card.
3. Neither of the above two methods can be handled. You can sue A in court and ask for confirmation that it belongs to you. A will help you with the transfer procedures. And apply to the court to seal up this property to ensure smooth implementation. The evidence you need to prepare includes: the index transfer agreement, all payment documents and vouchers, the evidence that the house is now in your charge, the purchase contract and real estate license signed by A, and A can entrust a lawyer or relative to appear in court to respond to the lawsuit, without having to come to respond in person. This situation belongs to the pretext of buying a house. As long as it does not infringe on the public interest (for example, the transfer of affordable housing places is generally not protected), the actual owner will generally be the investor. After the judgment, you apply for enforcement, and the court goes to the Housing Authority to assist in the transfer procedures, so you can handle the transfer yourself, so you need to pay more legal fees and enforcement fees. Of course, A can also reach a mediation with you without a court decision. The court will send you a conciliation statement (which has the same effect as the judgment, and you can apply for compulsory execution), and you can also collect legal fees by half.
Finally, it is suggested to transfer the house as soon as possible, because now the house is under the name of A, A can sell the mortgage, and if A is involved in litigation, the creditor can also seal up the property. None of these three situations is good for you.
Correct me, what you said about the index transfer agreement is not protected by law, which is not completely correct. As long as the intentions of both parties are true and do not violate the mandatory provisions of the law, they are all valid. If you didn't have the right to dispose of it at that time, it is also effective to obtain the corresponding rights afterwards.
It is inconvenient to type on the mobile phone. If you are not clear, you can ask me supplementary questions. I hope it helps you.
