The store is rented out to others as a kindergarten. Can I lock the door if I owe the rent?

You can lock the door, but you can't touch the contents.

1. The tenant's default on rent constitutes a breach of contract. The landlord can ask him to pay, and if the tenant still fails to pay the rent, the landlord has the right to terminate the contract.

Before the contract is terminated, the landlord had better not have physical conflict with the tenant. Because there is a lease contract between the landlord and the tenant, the disputes arising from the lease contract belong to the category of civil cases and should be under the jurisdiction of the court, but the police station has no jurisdiction.

3. If the conflict between the landlord and the tenant causes personal injury, the landlord will be subject to administrative punishment for violating the Law on Public Security Administration Punishment. If the other party is seriously injured, the landlord will bear criminal responsibility.

In short, if the tenant pays the rent, the landlord can exercise the right to cancel. If the tenant refuses to change the house after the contract is terminated, the landlord can take back the house by suing the court.
