Linked to other companies to sign maintenance contracts with the property, and now there are problems, and the owners sue us.

First of all, you should be responsible.

A contract signed by borrowing the official seal of another unit is a fraudulent contract. No matter what role the property management company plays, you first have the fact of subjectively cheating the owner. As for how the owner knows the inside information, this is very simple. The owner will go directly to the company that lent you the qualification survey. I don't believe people will take responsibility for this. )

As for the responsibility of the property management company, he signed this AB contract with you, which naturally deceives the owner.
