Which local department does the enterprise real estate property right survey consult?

Which local department should be consulted in the investigation of enterprise real estate property rights; I went to the Housing Authority (real estate trading center) to find out the situation:

Because only the real estate trading center has comprehensive real estate information for the record.

However, if you want to consult real estate information, you need a written investigation letter from the judicial department to consult. Because both unit and personal property are private.

It's just the price of the unit, and it is very likely that the real estate trading center will not receive it.
