Construction Machinery Transfer Registration and Change of Registered Details — Checking Document Mismatches That Lead to Rejection

Procedure

1. 1. Check the rights in the registration ledger

   Check in the construction machinery registration ledger whether a mortgage or seizure has been registered. Machinery with such an encumbrance, or machinery in the name of a business that has closed, can be transferred only after the rights are settled.

2. 2. Check that the documents match

   Check that the chassis number and the registration number on the transfer certificate do not differ from the registration ledger by even a single digit. A difference between the business registration address and the actual principal place of use is also a ground for rejection.

3. 3. Check documents according to commercial or private use

   For commercial-use construction machinery, unlike private-use machinery, documents related to the rental business are also reviewed. If you do not have the documents that fit the use, you will be asked to supplement them.

4. 4. File with the registration office

   Submit the Report of Change in Construction Machinery Registration Details (with the transfer certificate attached for a sale) to the competent registration office. Also check that payment of acquisition tax and the purchase of bonds have not been left out.

Required documents

• Report of Change in Construction Machinery Registration Details (a transfer of title by sale is also handled with this form)
• Transfer certificate (check that the chassis number and registration number match)
• Construction machinery registration certificate
• Identification or business verification documents of the transferor and the transferee
• Proof of the principal place of use
• Confirmation of acquisition tax payment and proof of bond purchase
• For commercial use: documents related to the rental business

Fees

Acquisition tax, bonds and registration fees are separate and depend on the machinery and the jurisdiction. In the market, agency fees generally range from tens of thousands to several hundred thousand won per case, and vary when rights need to be settled, such as clearing a mortgage or seizure or conversion to a corporation. We will review the registration ledger and advise you on the fee after a consultation.
