There is no clear validity period of the settlement voucher, but generally speaking, if it is more than 3 months from the date of issuance, it may not be processed. Because the bank stipulates that if the borrower has repaid the loan on time and the mortgaged things have gone through the mortgage cancellation procedures, the bank will issue a loan settlement certificate after the loan is settled. Proof requires the borrower to go to the lending institution in person, which can usually be completed on the same day.

It should be noted that the regulations of different banks may be different, so it is recommended to check the relevant regulations of your bank first.
