Start with unpaid status and possession
Sections 45–49 of the Sale of Goods Act, 1930 address unpaid-seller status and lien. An unpaid seller in possession can retain goods for the price in the stated section 47 circumstances: no credit stipulation, expired credit, or buyer insolvency. Do not treat an overdue debtor balance as a general right over every asset of the buyer. Identify the sale goods and who actually possesses them. UP Commercial Tax Department: Sale of Goods Act, 1930, sections 45–49.
Reconcile price evidence separately
Section 45 includes where the whole price has not been paid or tendered, and conditional negotiable-instrument payment where its condition fails through dishonour or otherwise. Keep the invoice, credit terms, receipts and any instrument status together. Our practical schedule shows the unpaid price as a debt measure; it does not pretend that a proportionate number of units must always be released for every rupee received. UP Commercial Tax Department: Sale of Goods Act, 1930, sections 45–49.
Read the credit and custody facts
A sale on unexpired credit to a solvent buyer is different from expired credit or insolvency. Confirm the actual due terms rather than inserting a standard number of days. Section 47(2) also recognises possession as the buyer's agent or bailee. The capacity in which goods are held therefore needs documentation, not an assumption that ownership and custody are the same question. UP Commercial Tax Department: Sale of Goods Act, 1930, sections 45–49.
Part delivery needs its own assessment
Section 48 permits lien on the remainder after part delivery unless the circumstances show agreement to waive it. Keep released and retained quantities in one goods register, and document the release terms. A quantity subtraction can establish what remains physically held; it cannot by itself establish whether lien was waived. Avoid warehouse instructions that promise release without preserving the intended legal position. UP Commercial Tax Department: Sale of Goods Act, 1930, sections 45–49.
Check for termination before relying on lien
Section 49 addresses loss through delivery to a carrier or other bailee for transmission without reserving disposal rights, lawful possession by the buyer or agent, and waiver. Obtaining a decree for price alone does not end lien. Retention, stoppage in transit and resale are distinct remedies; this guide does not infer an unrestricted resale power from a lien or authorise seizure after lawful delivery. UP Commercial Tax Department: Sale of Goods Act, 1930, sections 45–49.
Use a release decision supported by evidence
Our recommended file combines contract terms, payment status, custody, release documents and the legal review. The statutory text is available from the Uttar Pradesh Commercial Tax Department; the analysis here concerns the central sections identified, not a state-specific land or tax recovery process. The examples assume no overriding contract, document-of-title issue or other fact defeating the stated right. Values exclude tax and other charges.

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: No credit and part price unpaid
A sale price is ₹5 lakh, ₹2 lakh is paid, and the seller retains all identified goods with no credit stipulation. Unpaid price is ₹3 lakh. Assuming the other lien conditions remain satisfied, the working does not automatically convert that amount into a right to seize unrelated buyer goods.
Illustrative example 2: Credit has not expired
The agreed contract fixes 31 October 2026 as the payment due date. Review is on 20 October, eleven days earlier, and the buyer is assumed solvent. The expired-credit trigger is not established merely because a ₹4 lakh invoice is still unpaid.
Illustrative example 3: Credit has expired
Keep the agreed 31 October 2026 due date but review on 2 November. Two calendar days have elapsed after that date. With goods still possessed and no termination or waiver assumed, the expired-credit limb is relevant. This example does not impose a universal two-day grace period.
Illustrative example 4: Remainder after part delivery
A seller held 100 identified units and delivered 40. Physical remainder is 60 units. At the illustrative contract rate ₹1,000 each, that remainder has a ₹60,000 contract-price reference, but section 48's waiver review still determines whether lien persists; quantity arithmetic is not the legal test.
Illustrative example 5: Payment instrument dishonoured
Price is ₹6 lakh. A verified unconditional cash receipt covers ₹1 lakh; a ₹5 lakh instrument received only as conditional payment is dishonoured. The unpaid-price reconciliation remains ₹5 lakh on these stipulated facts. Preserve dishonour evidence rather than treating an unfulfilled conditional receipt as settled cash.
Illustrative example 6: Buyer lawfully receives all goods
Of 80 units, 30 and then 50 are lawfully delivered to the buyer, leaving zero units in the seller's possession. An unpaid ₹2 lakh balance remains a debt, but the former possessory lien is not maintained merely by keeping the invoice open.

Sixteen practitioner FAQs
1. Does every overdue invoice create a lien on all buyer assets?
No. Identify the sale goods and the possessory right.
2. Must the whole price be unpaid?
Section 45 includes the case where the whole price has not been paid or tendered.
3. Can a dishonoured conditional instrument matter?
Yes. Retain the condition and dishonour evidence.
4. Does unexpired credit equal expired credit?
No. Read and compare the actual due terms.
5. Is commercial concern alone proof of insolvency?
Do not substitute an unsupported label for the legal facts.
6. Can the seller hold goods as bailee for the buyer?
Section 47(2) addresses that capacity; document it.
7. Does part delivery necessarily waive lien on the rest?
No. Examine the circumstances under section 48.
8. Can the remaining quantity be calculated without deciding waiver?
Yes. Keep physical arithmetic and legal conclusion separate.
9. Does a payment require proportionate unit release under these examples?
No automatic proportional-release rule is asserted.
10. Can lawful delivery end the possessory lien?
Yes, under the stated termination framework.
11. Should carrier handoff terms be reviewed?
Yes. Reservation of disposal rights matters under section 49.
12. Does a decree for price alone end lien?
Section 49(2) says it does not.
13. Is lien an automatic right of resale?
No. Resale requires its own applicable analysis.
14. Can an unpaid balance justify taking goods back after lawful delivery?
Do not infer a seizure right from this lien guide.
15. What should stores receive before withholding release?
A clear authorised instruction tied to identified goods and a supported review.
16. What is the main reconciliation?
One record of price status, possession, deliveries and events affecting lien.
Conclusion
An unpaid invoice alone does not establish a continuing lien over goods. Test possession, the section 47 trigger and any event ending the lien before withholding delivery.
