Transfer Of Ownership And Thor Tor 3

Dear All,

I legally owned a condominium since 3 years and I am planning to sell it for buy a bigger one.

Does the Land department will accept to transfer ownership if the funds used for pay the new unit are partially issued from a previous buying/sale ?

May I use the previous Thor Tor 3 (from 3 years ago) for show the money transfered from abroad in foreign currency to proceed the transfer of ownership of the new condo ?

This is interesting question

Thanks
