Guarantee is a secondary repayment support where another party agrees to pay or perform if the borrower defaults. In MSME lending, guarantees are commonly taken from promoters, group companies, directors, partners, or guarantee institutions to strengthen the lender’s recovery position. A guarantee does not replace the borrower’s own repayment capacity, but it gives the bank an additional legal claim. For example, a company loan may be backed by personal guarantees from directors so that the promoters remain accountable for repayment. The value of a guarantee depends on the guarantor’s net worth, enforceability, documentation, and willingness to support the account. The common mistake is to treat a guarantee as strong security without checking whether the guarantor actually has financial capacity and whether the guarantee documents are legally valid.
