I recently managed to take care of a major family matter—helping my mom sell her old house back in China. Since I live in Spain long-term and my mom is getting older, it would have been very inconvenient for her to handle all the paperwork alone. Therefore, the entire process was coordinated remotely by me, with a relative in China helping on the ground. It was quite a hassle, but I’ve gained a lot of experience, which I’m sharing today in hopes of helping others in a similar situation.

The Core Challenge: How to Obtain Legal Authorization?
The first problem to solve is legal authorization. Since we are not in China and the property is in our parents’ names, how can we legally represent them to sign documents and handle procedures? The answer is to obtain a notarized Power of Attorney (POA). This document is crucial; it’s an official authorization letter that grants your agent in China the right to handle property matters on your parents’ behalf. There are two main ways to get this POA:
- Doing it in China: This is the most direct method, but for those of us living abroad, it’s too costly and difficult to schedule. I completely ruled out this option for my remote sale, which is a different scenario from selling property in Spain.
- At the Chinese Embassy/Consulate in Spain: This is the most common and reliable method. You’ll need to book an appointment on the embassy or consulate’s website in advance. The property owner (in my case, my mother, who also lives in Spain) must then go to the embassy or consulate in person with all the necessary documents. It’s crucial that the property owner attends personally to prove that the delegation of authority is voluntary.
Key Documents for the Power of Attorney Notarization
Make sure you have all the documents ready before going to the embassy or consulate to avoid a wasted trip. The requirements may vary slightly between different consular districts, but they generally include the following. Here is the checklist of documents I prepared, which you can use as a reference:
| Document Type | Details |
| Identification | Property owner’s passport and Spanish residence card (original and copy) |
| Chinese Identification | Property owner’s Chinese ID card and household registration book (Hukou) (original and copy) |
| Proof of Property | Property ownership certificate (original or a clear copy) |
| Agent’s Information | Copy of the agent’s Chinese ID card |
| Draft of POA | A pre-written draft of the Power of Attorney, clearly defining the delegated powers |
| Notarization Application Form | Downloaded from the embassy/consulate’s official website and filled out |
The content of the Power of Attorney must be extremely detailed, a lesson also applicable to processes like representing someone for a property purchase in Spain! For example, you must clearly authorize the agent to sign the sales contract, handle the property transfer, receive payments, and manage mortgage payoffs with the bank, etc. The clearer the authorizations, the smoother the process will be. The staff at the consulate even helped us review the document to ensure no critical powers were missed.
Once processed, you will receive several copies of the notarized document; one is kept by the embassy/consulate, and the rest are for you. Remember to send the original document to your agent in China via a reliable international courier, as they will need to present the original at every subsequent step. With that, the most critical step is complete! Your agent in China can then take this POA and their ID to handle the rest of the selling process as if they were the property owner. The whole process is tedious, but it’s manageable if you take it one step at a time. I hope my experience can be a helpful reference for you!
