Does the property or developer have the right to detain the real estate license?

Neither the property nor the developer has the right to detain the real estate license.

It's just that he has the convenience of using the real estate license and needs the owner to do this and that. Many owners can do many things in order to get the real estate license (such as long-term arrears of property fees, water fees, electricity fees, etc.). However, if it is not superficial, the property has absolutely no right to seize the property certificate. The property company is just talking about scaring the owners.
