[Legal Advice] Can the corridor between two communities be locked and blocked by one of them privately?

1. First of all, it is necessary to make clear whether the corridor connected between A and B belongs to A community or B community.

2. If it belongs to Community A, and you also said, this aisle is not the only pedestrian corridor. At this time, the practice of Community A is not illegal and belongs to the right of self-punishment.

The situation you described doesn't conform to the "adjacent relationship" in law. If it is the only necessary passage, according to Article 10 1 of Opinions on General Principles of Civil Law, the owner or user shall not block the necessary passage formed in history in the building owned or used by one party. If the blockage affects the production and life of others, and others request to remove the blockage or restore it to its original state, it shall be allowed. However, if conditions permit, another channel can be opened. Therefore, B can negotiate with A to find a feasible solution.

4. There is another way. According to the provisions of Chapter 14 of the Property Law, Party B and Party A can sign an easement contract to establish an easement for the corridor. Both parties can agree on the content of easement by themselves.
