Is it legal for property service company A to transfer the whole service target to property service company B?

Under normal circumstances, it is against the Property Management Regulations that Property A hands over all the projects it manages to Property B. ..

But there are always exceptions, and in some cases, this practice is legal.

1, Property B acquires Property A (or both companies jointly operate). According to the principle of business combination, when Property B obtains Property A, it undertakes its creditor's rights and debts and takes over all its business.

2. Property A goes bankrupt and the enterprise is dissolved. In order to protect residents and households from the influence of property management and ensure the normal life and residence of residents, according to the principle of emergency takeover, the regional administrative department has the right to initiate emergency management measures for projects without industry committees, first arrange a property company to provide temporary services, and then formally hire a property company after the establishment of community industry committees. Accordingly, the sub-district office can first contact the temporary management of B property and sign a property contract.

3. Property A has been revoked the qualification of property management by the Housing Authority for its own reasons, and no longer has the business qualification of property management, so it must be withdrawn from the projects it manages. Similarly, according to the principle of emergency takeover, the sub-district office can entrust property B to temporarily take care of it.

According to your description, if there are government departments involved, it should belong to one of the above situations, then the practice of sub-district offices and community management committees is reasonable and legal.
