Find the agreement before moving the balance
Under section 62 of the Indian Contract Act, 1872, the parties can agree to substitute a new contract, rescind or alter the old one. Where a debtor is being replaced, establish who agreed to the substitution and whether the creditor actually accepted the incoming party instead of the original debtor. Illustration (a) to section 62 shows a creditor and both debtors agreeing that the incoming debtor will be liable instead of the original debtor. A journal or payment instruction alone does not establish substitution. Under section 41, acceptance of performance from a third person prevents enforcement of that performance again against the original promisor; it does not by itself substitute the payer for the unpaid balance.

Separate a substitution from an alteration
A three-party deed can evidence the creditor’s acceptance of the incoming debtor and the terms on which the outgoing debtor is released. A maturity or instalment amendment with the same debtor can be an alteration, with the revised obligations applying under the agreed terms. Spell out whether accrued interest, disputed invoices, deposits and performance obligations transfer, survive or are excluded. If the creditor retains a claim against the old debtor, identify the exact obligation that was replaced; avoid describing the entire original debt as discharged. A promisee’s waiver or acceptance of satisfaction under section 63 raises a separate question; an accepted reduced payment does not by itself evidence substitution of the debtor.
Build an effective-date bridge
Set out the original principal, payments received, accrued charges, disputed items and the balance expressly transferred. Match that amount to the opening balance under the new agreement. Where consent, approvals or payment are conditions precedent, keep the old position open until their satisfaction is evidenced. Record any reserved claims by party, amount and source.
Protect collateral and separate statutory work
Identify guarantees, security, insurance, title documents and restrictive covenants. Obtain legal review and required consents before assuming security follows the revised liability; section 133 addresses variance without a surety’s consent for subsequent transactions. Also consider section 134 where the creditor releases the principal debtor or otherwise causes a legal discharge. Check the guarantee wording and any applicable consent or exception. Have the accounting team assess derecognition, the tax team assess tax and invoicing, and the legal team assess stamp duty, registration or charge steps as applicable. The contractual bridge is evidence for these decisions, not a substitute for them.
Six worked illustrations
All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.
Illustrative example 1: Full substitution
A tripartite agreement transfers ₹48 lakh principal and ₹2 lakh accrued interest and releases the former debtor when effective. The new contractual opening is ₹50 lakh, and the replaced balance is nil.
Illustrative example 2: Retained claim
The original balance is ₹75 lakh. The agreement transfers ₹60 lakh and reserves ₹15 lakh against the original debtor. Show ₹60 lakh and ₹15 lakh on separate lines, tied back to ₹75 lakh.
Illustrative example 3: No creditor assent
A customer’s subsidiary sends ₹9 lakh accepted on account of a ₹30 lakh balance. With no substitution or release, the remaining original balance is ₹21 lakh and the subsidiary has not become debtor merely by paying.
Illustrative example 4: Deferred effectiveness
A signed deed requires a ₹4 lakh payment before a ₹24 lakh principal balance can transfer. If payment is credited to principal and the condition is satisfied, transfer ₹20 lakh; before satisfaction the transfer amount is zero.
Illustrative example 5: Same debtor, revised schedule
A ₹36 lakh principal balance is rescheduled from three ₹12 lakh instalments to six ₹6 lakh instalments, with no other changes. Principal remains ₹36 lakh with the same obligor.
Illustrative example 6: Cut-off receipts
A ₹45 lakh debt is due to transfer at month end. The original debtor pays ₹7 lakh before the cut-off and the parties confirm no other movement; ₹38 lakh transfers.

Sixteen practitioner FAQs
1. Does a new invoice recipient become the debtor?
Only if the underlying agreement and facts support that result.
2. Does the outgoing debtor always have to be fully released?
A substitution may be confined to identified obligations; expressly record anything reserved.
3. Can an affiliate pay without becoming a debtor?
Yes. Under section 41, accepted third-party performance prevents the creditor from enforcing that performance again against the original debtor. It need not substitute the payer for the outstanding debt.
4. Is a payment plan always a novation?
No. With the same debtor and debt, it may simply alter payment terms.
5. Can a signed deed be conditional?
Yes. Verify its conditions and actual effective date.
6. Is a draft without creditor acceptance sufficient?
No. Retain the executed agreement or other persuasive evidence of assent.
7. Can past interest stay with the former debtor?
Yes if validly reserved. Show it outside the transferred principal.
8. How should disputed invoices be handled?
Identify each dispute and say whether it transfers, stays or is settled.
9. Can parties release only some obligations?
Record the precise scope, including any contractual obligations outside the balance.
10. What if the incoming debtor later defaults?
Check the new agreement and any surviving guarantees or reserved rights.
11. Can a guarantor be assumed to remain liable?
No. Review the guarantee and consent, including section 133 where relevant.
12. What if there is a deposit on the old account?
Document whether it transfers, is repaid or is applied under the agreement.
13. Should accounting follow the deed date?
Assess the effective contractual change and applicable accounting rules; the signature date may differ.
14. Does a new counterparty require a fresh onboarding file?
Operationally yes where controls require it; do not treat onboarding as consent.
15. What if invoices are credited after transfer?
Allocate them under the agreed cut-off and reconcile both counterparties.
16. Is novation the same as waiving the unpaid balance?
No. Waiver or accepted satisfaction under section 63 requires its own analysis.
