Today is the settlement date which I have worked for the seller. That reminded me of one tip that we should mortgage your properties.
The necessary documents to change the ownership are as below.
Notice of information for registration identification (which only the owner knows)
Company stamp (which the owner keeps)
Certificate of the company seal impression (the only owner can apply for the legal affairs bureau)
Certification of whole data for the property (anybody can take)
Certification of assessed value of fixed assets (the only owner can apply for the legal affairs bureau)
To change the ownership, the sellers are required to put your seal and visit the legal affairs bureau) However you can assign a representative to acquire the documents. Some owner who has lack of attention to read the documents would put his seal on any documents. As most owners has lack of trading opportunities, once they rely on someone, they would put his seal on any document.
When owners intend to sell the property with the mortgage (even when not intending to), it will be reviewed by loan holder. It means the mortgage is strong deterrent to the trouble.
