Can a bank legally refuse to exchange an old but valid series note?
No — a bank cannot legally refuse to exchange a note that is current legal tender, regardless of how old the series is. Legal tender status is determined by law (RBI Act Section 26), not by the bank's preference. Any note that has not been formally demonetised by gazette notification under Section 26(2) retains its legal tender status and must be accepted and exchanged by banks. The bank's obligation is imposed by RBI Master Circulars on Note Exchange. Refusal is a deficiency of service remediable through the Banking Ombudsman and consumer forum.
Legal tender is the bank's obligation, not discretion
The RBI Act Section 26(1) makes every bank note issued by the Reserve Bank legal tender at any place in India in payment or on account for the amount expressed therein. A note that is legal tender must be accepted in payment and for exchange. A bank that refuses to accept or exchange a legal tender note — because it is an 'old series,' because the teller is unfamiliar with it, or for any other reason — is refusing to fulfil an obligation imposed by law.
The relevant categories: ₹100, ₹50, ₹20, ₹10, ₹5, ₹2, and ₹1 notes from all series that have not been formally demonetised remain legal tender. The Mahatma Gandhi (New) Series introduced from 2016 is current; the Mahatma Gandhi Series introduced from 1996 is still legal tender; older series that were never formally demonetised are still legal tender. The ₹2,000 note (withdrawn May 2023) retains legal tender status but exchange is only at 19 RBI Issue Offices.
The condition exception — issuable vs non-issuable
The obligation to exchange applies to notes in issuable condition. A note that is extensively mutilated — missing large portions, or in a state where its value cannot be determined — may fall under the Note Refund Rules 2009 rather than simple exchange. But a note that is merely old, worn, or from an unfamiliar series is in issuable condition — the teller's unfamiliarity with the series does not create a right to refuse.
The collector's practical response to refusal
When a bank teller refuses to exchange a valid old series note: Step 1 — ask politely for the teller's reason. Most refusals are from unfamiliarity, not policy. Step 2 — ask to speak to the branch manager. A manager should know the RBI's note exchange obligations better than a teller. Step 3 — if still refused, ask for the refusal in writing (most banks will not give this, which itself is telling). Step 4 — file a written complaint at the branch with date, time, teller's name if possible, and the note's details. Step 5 — file with the RBI Banking Ombudsman (bankingombudsman.rbi.org.in) under the Integrated Ombudsman Scheme 2021. Step 6 — consumer forum complaint for deficiency of service.

Bank cannot refuse legal tender notes — RBI Act §26(1). Old series notes that have not been demonetised by §26(2) gazette notification: must be accepted. Refusal = deficiency of service. Steps: politely inform teller of RBI obligation → branch manager → written complaint at branch → RBI Integrated Ombudsman Scheme (bankingombudsman.rbi.org.in) → consumer forum. Exception: ₹2,000 notes (exchange only at 19 RBI Issue Offices). Exception: mutilated notes (Note Refund Rules 2009 apply, Q309).
