Legal analysis: unlimited times. There is no clear limit on how many times a loan guarantor can guarantee. In other words, you can vouch for others indefinitely as long as the actual situation permits. For example, after the loan guarantee period has expired and the borrower's loan has been paid off, the guarantor can guarantee for others again, and the first guarantee has no effect on the second guarantee.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 692 The suretyship period is the period during which the surety assumes the suretyship responsibility, and may not be suspended, interrupted or extended.

The creditor and the guarantor may agree on a guarantee period, but if the agreed guarantee period expires before or at the same time as the performance period of the principal debt, it is deemed that there is no agreement; If there is no agreement or the agreement is unclear, the guarantee period shall be six months from the date of expiration of the main debt performance period.

Where the creditor and the debtor have not agreed or clearly agreed on the time limit for the performance of the principal debt, the guarantee period shall be counted from the date when the grace period for the creditor to request the debtor to perform the debt expires.

Article 698 The guarantor of a general guarantee provides the creditor with the true information of the debtor's property available for execution after the maturity of the principal debt. If the creditor gives up or is slow to exercise his rights, which makes the property unenforceable, the guarantor will no longer bear the guarantee liability within the range of the value of the property available for execution.
