The seller must first go to the Fiscalia (in Santo Domingo, this is in Honduras just about 2 blocks above Independencia) and get a certificate that verifies the vehicle is not stolen. This means a queue of about 5 to 15 cars to go in for the inspection one morning, and then present their documents to the office here which will then have the certificate ready in 2 or 3 or 4 days later, depending if they have luz or ambition .(Cost here = RD$80.)
The buyer pays his attorney to write up the sales contract, and to then legalize it. Then the buyer and seller meet, the contract is signed by both parties, each gets a copy, and the money for the vehicle changes hands. Cash is king here - don't take a check or partial payment.
Then the buyer must go to the DGII office with the original Matricula and sales contract , and pay the taxes and obtain the Traspaso. The taxes on a vehicle being sold for RD$260,000 , including all other fees , will run just over RD$11,000. (but no, I don't know the rate, just from prior experience that this is roughly the amount that will be paid at this price).
