No appropriation by either party is the entry test
Section 61 of the Indian Contract Act, 1872 supplies the stated default where neither party appropriates payment: debts are discharged in time order, with proportionate treatment for equal standing. Its wording includes debts whether or not recovery is limitation-barred. Checked on 28 October 2026, this guide focuses on that fallback allocation, distinct from the debtor's invoice-specific direction under section 59 or the creditor's section 60 discretion. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.
Investigate remittance evidence before using ageing
Review payment advice, correspondence, collection requests, receipts and the contractual terms. A missing invoice number in the bank feed does not establish that neither party appropriated. A particular amount and surrounding correspondence may identify the debt. Record the supported legal conclusion before applying a default spreadsheet rule. These models assume ordinary unsecured principal debts between the same parties, no contrary agreement, no decree-specific appropriation issue and no effective appropriation by either party. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.
Establish legal time order
Build a debt register with the evidence supporting each debt's chronological standing. Do not assume that an ERP upload date or a later migration reference determines legal order. Preserve disputed dates and balances separately. In the examples, the time order is stipulated; the algorithm does not decide when a disputed debt legally arose or became payable. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.
Split equal-standing balances rather than choosing the largest
Within an equal-standing group, apply the available payment in proportion to each outstanding debt. For ₹30,000 and ₹70,000 equal-standing debts, a ₹20,000 payment splits 30:70. Only after an older group is fully discharged does the remaining payment pass to the next chronological group. Document rounding for actual paise allocations and ensure total allocated equals actual payment; the examples use exact amounts without rounding residuals. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.
Keep limitation and allocation conclusions separate
The statutory allocation wording does not automatically create a fresh enforceable claim for the unpaid remainder of a time-barred debt. Limitation, acknowledgments, part-payment consequences and any fresh promise have their own requirements. Do not convert an internal reallocation entry into a debtor acknowledgment. Preserve historical payment applications rather than moving them between invoices merely to improve the ageing report. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.
Reconcile receipts and closing debts
For every payment show opening balances, the applicable chronological group, allocations and closing balances. An amount exceeding all stated debts remains a separate unapplied amount requiring investigation, not a negative invoice invented as a refund entitlement. Confirm the debt population is complete and separately review interest, costs, security or court orders where present. Retain the source advice and review conclusion beside the calculation. India Code: Indian Contract Act, 1872, sections 59–61, particularly section 61.

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Use the oldest stipulated debt first
Assume older debt ₹40,000, later debt ₹60,000 and payment ₹50,000, with section 61 conditions established. Apply ₹40,000 to the older debt and ₹10,000 to the later; ₹50,000 remains on the latter.
Illustrative example 2: Split equal standing proportionately
Assume equal-standing debts ₹30,000 and ₹70,000 and available payment ₹20,000. Allocate ₹6,000 and ₹14,000. Closing balances are ₹24,000 and ₹56,000, total ₹80,000.
Illustrative example 3: Clear an older group before the next
Assume oldest debt ₹20,000, then equal-standing debts ₹30,000 and ₹50,000, and payment ₹60,000. Clear ₹20,000 first. Split the remaining ₹40,000 as ₹15,000 and ₹25,000; those debts close at ₹15,000 and ₹25,000.
Illustrative example 4: Limitation status does not itself change this stipulated order
Assume older limitation-barred debt ₹15,000, later debt ₹25,000 and unappropriated payment ₹10,000. Under the stipulated section 61 route, ₹10,000 goes to the older debt, leaving ₹5,000 and ₹25,000. No revival of enforceability is assumed.
Illustrative example 5: A second payment uses remaining balances
Assume equal-standing debts ₹40,000 and ₹60,000. First payment ₹20,000 splits ₹8,000/₹12,000, leaving ₹32,000/₹48,000. A second ₹30,000 splits ₹12,000/₹18,000, leaving ₹20,000/₹30,000.
Illustrative example 6: Isolate excess receipt
Assume the complete established debt population is ₹10,000 and ₹15,000, and receipt ₹30,000. Debts discharge in full and ₹5,000 remains unapplied for separate investigation. The calculation does not establish the legal character or refund terms of that excess.

Sixteen practitioner FAQs
1. Does a missing invoice number automatically invoke section 61?
No. Investigate directions, circumstances and creditor appropriation first.
2. Is this the same as section 59?
No. Section 59 concerns a debtor-indicated application; section 61 is the stated fallback.
3. Can creditor appropriation be ignored?
No. Establish that neither party appropriated before using this guide's default model.
4. Does the oldest ERP upload always come first?
No. Establish the debt's legal chronological standing.
5. How are equal-standing debts treated?
Proportionately to their outstanding amounts in the applicable group.
6. Can the largest equal-standing invoice be cleared first merely for convenience?
That would not follow the proportionate allocation used under the stated rule.
7. When does payment pass to a later group?
After the older group's relevant debts have been discharged.
8. Do the examples allocate interest or litigation costs?
No. They expressly isolate ordinary principal debts without those complications.
9. Can a court order require a separate analysis?
Yes. Do not transfer the simple model to decree or other special appropriation circumstances automatically.
10. Does the wording include limitation-barred debts?
Yes, subject to establishing the actual section 61 conditions.
11. Does that automatically revive an unpaid barred balance?
No. Enforceability and revival require their own legal analysis.
12. Is an internal ledger entry a debtor acknowledgment?
Do not treat it as one merely because the creditor posted it.
13. How should the second payment be calculated?
Use the remaining debt balances and the continuing applicable order or equal-standing proportions.
14. Can allocations exceed the actual receipt?
No. Reconcile the total allocation to actual funds received.
15. What happens to money exceeding all established debts?
Record it separately and investigate its legal character rather than inventing a negative debt.
16. What evidence should be retained?
Remittance records, appropriation review, debt standing, calculations and the closing account reconciliation.
Conclusion
Apply section 61 only after excluding an effective appropriation by either party, then discharge debts chronologically and split equal-standing debts proportionately.
