To get a real estate license, you need the signature of the party concerned, not the signature of the neighbor.

Legal basis:

Article 7 of the Provisional Regulations on the Registration of Real Estate shall be handled by the real estate registration agency of the people's government at the county level where the real estate is located; The people's governments of municipalities directly under the central government and cities divided into districts may determine the real estate registration agencies at the same level to uniformly handle the real estate registration in their respective jurisdictions. Real estate registration across county-level administrative regions shall be handled by real estate registration agencies across county-level administrative regions respectively. If it cannot be handled separately, it shall be handled through consultation by the real estate registration agency across county-level administrative regions; If negotiation fails, it shall be handled by the real estate registration department of the people's government at the next higher level.
