Classify the creditor's conduct before assessing discharge
Under section 135 of the Indian Contract Act, 1872, a contract between creditor and principal debtor to compound, give time or not sue discharges the surety unless the surety assents. Section 137 distinguishes mere forbearance to sue or enforce another remedy: absent a contrary guarantee provision, that alone does not discharge the surety. Read the documents and actual dealings to establish whether there is a binding contract rather than treating every delay as a standstill.
Read the applicable text: Indian Contract Act, 1872, sections 133 and 135–141.
Identify who agreed and what the promise covered
Section 136 states that a contract to give the debtor time made between the creditor and a third person, rather than with the debtor, does not discharge the surety under that rule. Identify each signatory, authority and the covered facility. A group company can have a different legal identity from the principal debtor. Review the complete correspondence and conditions, including whether a proposed term sheet ever became effective. If a third person signed as the debtor’s authorised representative, establish who actually contracted before treating the case as an agreement with a third person under section 136.
Check surety assent and contractual exceptions
Separate notice from assent and identify which surety agreed, to what and when. Assess any advance-consent language against the actual arrangement. A contrary provision in the guarantee matters to the section 137 analysis. Do not reuse assent for one facility or standstill to justify a broader arrangement without support.
Reconcile the exposure and preserve other issues
Document debt, enforceable coverage and unresolved items by facility and surety. Separate the surety position from the debtor’s liability under the applicable agreement, and review limitation and other discharge grounds independently. Section 138 also provides that releasing one co-surety does not discharge the others or free the released surety from responsibility to the other co-sureties. A change in original contract terms or a loss of security can raise different questions under sections 133 or 141. The illustrations assume enforceable obligations and no other discharge unless stated.
Six worked illustrations
All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.
Illustrative example 1: Binding extension without assent
A borrower owes ₹32 lakh under a guarantee otherwise covering the full amount. The creditor and borrower enter a binding extension, with no surety assent. On the stated section 135 assumptions the ₹32 lakh is removed from the surety working; the borrower balance is assessed separately.
Illustrative example 2: Mere delay after maturity
A loan matured on 1 August 2026 and the creditor first pursues collection on 21 August. Twenty calendar days elapsed. With no agreement or contrary guarantee term, delay alone does not remove the assumed ₹24 lakh surety exposure.
Illustrative example 3: Two facilities, one standstill
A binding standstill covers a ₹40 lakh facility without assent; a separate ₹18 lakh facility is outside it. Out of ₹58 lakh gross exposure, ₹18 lakh remains in the illustrative surety working, subject to separate legal checks.
Illustrative example 4: Agreement made with a third person
A creditor contracts with a third person, rather than the debtor, to give time on a ₹15 lakh loan. The relevant guarantee is capped at ₹12 lakh. On the stated section 136 facts the working cap remains ₹12 lakh, before other issues.
Illustrative example 5: Assent covers only the identified facility
A surety consents to a binding extension on a ₹26 lakh facility and does not assent to a separate binding extension on a ₹9 lakh facility. The assumed section 135 split is ₹26 lakh retained and ₹9 lakh excluded.
Illustrative example 6: Identify duplicated exposure
The same ₹11 lakh loan appears in two collection reports, and one separate ₹7 lakh balance appears once. The distinct exposure is ₹18 lakh before applying the relevant legal treatment, not ₹29 lakh obtained by counting the ₹11 lakh twice.
