Adjudication of Stamp Duty: Meaning and Process (2026 Guide)

Understand the adjudication of stamp duty in India. Learn what stamp adjudication means, when it is required, how the process works in Karnataka, penalties for under-stamping, and how to apply.
Quick Summary (TL; DR)
Adjudication of stamp duty is the process of getting the correct stamp duty on a document officially determined and certified by a competent authority, typically the District Collector or Collector of Stamps.
It is required when the stamp duty paid on a document is unclear, disputed, or when a foreign document needs to be stamped for use in India.
In Karnataka, adjudication is governed by the Karnataka Stamp Act, 1957. The application is made to the District Collector or the authority designated under the Act.
An under-stamped document is not invalid, but it attracts a penalty of up to 10 times the deficit stamp duty if not adjudicated and the deficit paid.
You receive a Power of Attorney executed in the United States. Before it can be used for property transactions in Karnataka, it needs to be properly stamped. But what is the correct stamp duty? Who determines it?
Or you purchase a property and later discover the stamp duty paid on the sale deed may have been calculated on a lower value than what the law requires. What happens now?
Both situations lead to the same process, the adjudication of stamp duty. It is the official mechanism through which the correct stamp duty on a document is determined, certified, and collected.
What is the Meaning of the adjudication of Stamp Duty?
When the correct stamp duty on a document needs to be officially determined, the District Collector or Collector of Stamps steps in. That process of examination and official determination is the adjudication of stamp duty.
Both the Indian Stamp Act, 1899, and the Karnataka Stamp Act, 1957, give any person the right to approach the Collector of Stamps when there is a genuine doubt about the stamp duty chargeable on a document.
What Does Adjudication Establish?
The correct stamp duty chargeable on the document
Whether the document is properly stamped, under-stamped, or unstamped
The amount to be paid if the document is under-stamped
The penalty applicable to the deficit
An official certification that the document is now duly stamped after payment
Adjudication does not make a document legally valid from scratch. It certifies that the stamp duty has been correctly determined and paid, after which the document can be used for its intended legal purpose.
When Is Adjudication of Stamp Duty Required?
Adjudication is not part of every property transaction. For most documents, stamp duty is paid at the time of execution, and registration handles the rest. It becomes necessary only in specific situations:
1. Foreign Documents Being Used in India
When a legal document is executed outside India, such as a Power of Attorney signed in the USA, UK, UAE, or any other country, it needs to be stamped for use in India. Foreign documents are not stamped as per Indian rates at the time of execution abroad.
Once in India, the document must go to the Collector of Stamps within the time the law allows. The Collector works out the correct stamp duty under Indian law, the document is stamped, and it can then be used legally.
This is particularly relevant for NRIs who execute Powers of Attorney abroad for managing property in India. After apostille or consular attestation, the GPA must be adjudicated in India before it is accepted by the Sub-Registrar's office.
2. Under-Stamped Documents
A document is under-stamped when stamp duty less than what the law requires has been paid on it. This can happen due to:
Deliberate undervaluation of the property to reduce stamp duty
Genuine errors in calculating the applicable stamp duty
Changes in stamp duty rates after the document was executed
Disputes about the nature of the transaction and the applicable stamp duty rate
An under-stamped document cannot be used as evidence in court and may be refused by registration authorities. Adjudication allows the deficit stamp duty and applicable penalty to be paid, after which the document is certified as duly stamped.
3. Documents of Uncertain Stamp Duty
When a document involves a complex transaction, and there is genuine uncertainty about which stamp duty rate applies or about the value on which stamp duty should be calculated, the parties can voluntarily approach the Collector for adjudication before or after execution.
4. Disputed Stamp Duty Assessments
When the stamp duty paid is questioned by the revenue authority.
For example, when the Sub-Registrar disputes the value declared for stamp duty purposes, the matter may be referred for adjudication to determine the correct duty.

What Is the Legal Basis for Stamp Adjudication in India?
Stamp adjudication in India is governed by two sets of laws:
Legislation | Scope | Relevant Sections |
Indian Stamp Act, 1899 | Central legislation: governs stamp duty on instruments at the national level | Sections 31 to 42 (Adjudication provisions) |
Karnataka Stamp Act, 1957 | State legislation: governs stamp duty on instruments in Karnataka | Section 31 and Schedule I (instrument-wise rates) |
Registration Act, 1908 | Governs registration of documents: links to stamp duty compliance | Section 17, 33, 35 |
Section 31 of the Indian Stamp Act, 1899, gives any person in doubt about the correct stamp the right to approach the Collector. The Collector is then required to examine the instrument and certify in an endorsement on the document itself, the correct duty chargeable.
In Karnataka, the Deputy Commissioner (DC) of the district functions as the Collector of Stamps for adjudication purposes. Applications are filed at the DC's office or the designated stamp authority office.
What is the Process for the adjudication of Stamp Duty in Karnataka?
The adjudication process in Karnataka follows these steps:
Confirm which document needs adjudication, whether it is a Power of Attorney, a sale deed, a lease deed, or another instrument
Draft the application addressed to the Deputy Commissioner (Collector of Stamps) of the relevant district
Submit the original document alongside supporting documents, like property details, market value, identity proof, and any related agreements
Pay the prescribed application fee at the DC's office
The Collector examines the document and determines the correct stamp duty
If the document is under-stamped, the Collector issues a notice of deficit and penalty
Pay the deficit stamp duty and applicable penalty within the time specified
The Collector endorses the document, certifying it is duly stamped
The document can now be used for registration, court proceedings, or any other legal purpose

Documents Required for Adjudication Application
Original instrument requiring adjudication (Power of Attorney, sale deed, lease deed, etc.)
Copy of the document for office records
Details of the property or transaction involved
Market value or guidance value of the property (if property-related)
Identity proof of the applicant
Address proof
Any supporting agreements or correspondence related to the transaction
Prescribed application fee (varies by district and document type)
What Are the Penalties for Under-Stamping in India?
Under-stamping is taken seriously under Indian stamp law. A document that has not been properly stamped attracts significant penalties.
Default | Penalty Under the Indian Stamp Act |
Under-stamped document | Penalty of up to 10 times the deficit stamp duty amount |
Unstamped document | Penalty of up to 10 times the full stamp duty amount |
Deliberate undervaluation | Penalty of up to 10 times the deficit plus potential prosecution |
Late payment of the deficit | Interest at the prescribed rates from the date of execution |
Using an under-stamped document | Document not admissible as evidence in court until the deficit is paid |
An under-stamped document is not automatically void. But until the deficit stamp duty and penalty are paid through adjudication, it cannot be used as evidence in court and may be rejected by registration and revenue authorities.
What Is the Difference Between Adjudication and Registration of a Document?
Adjudication and registration are two separate processes that often occur together in property transactions but serve entirely different purposes.
Factor | Adjudication of Stamp Duty | Registration of Document |
Purpose | Determines the correct stamp duty and certifies that the document is properly stamped | Records the document in government records and gives it public notice |
Authority | Collector of Stamps / Deputy Commissioner | Sub-Registrar of Assurances |
Governed By | Indian Stamp Act, 1899 / Karnataka Stamp Act, 1957 | Registration Act, 1908 |
Mandatory | Only in specific situations | Mandatory for immovable property documents above a certain value |
Outcome | Document endorsed as duly stamped | Document entered in the government register becomes a public record |
Sequence | Adjudication before registration for foreign documents | Registration after stamp duty is paid, and adjudication is complete |
For most property transactions in Karnataka, adjudication is not a separate step; stamp duty is paid at the time of registration, and the Sub-Registrar verifies it simultaneously. Adjudication becomes a separate process only when documents arrive from outside India or when under-stamping is discovered after the fact.
Adjudication of Stamp Duty for NRI Power of Attorney: Step by Step
This is the most common scenario where adjudication is required in Karnataka. Here is the complete process for an NRI GPA arriving from abroad:
NRI executes the Power of Attorney in the country of residence, notarised by a Notary Public
GPA is apostilled (for Hague Convention countries) or attested by the Indian Embassy / Consulate
Original GPA is sent to the authorised representative in India
Representative presents the GPA at the office of the Deputy Commissioner (Collector of Stamps) of the relevant district in Karnataka
An application for adjudication is submitted with the GPA and supporting documents
DC's office examines the GPA and determines the applicable stamp duty under the Karnataka Stamp Act
Stamp duty is paid, and the GPA is endorsed/stamped by the DC's office
Adjudicated GPA can now be presented at the Sub-Registrar's office for use in property transactions
Time limit: A foreign document must be presented for adjudication within 3 months of arriving in India. Presenting after this period may attract a penalty on top of the stamp duty.

What Are Common Situations Where Adjudication Becomes Necessary in Karnataka?
Situation | Why Adjudication Is Needed |
NRI Power of Attorney arriving from abroad | Foreign documents not stamped as per Indian rates must be adjudicated before use |
Property sold below the guidance value | Revenue authority disputes the stamp duty paid, and adjudication determines the correct amount |
Under-stamped sale deed discovered after registration | Deficit stamp duty and penalty must be paid through adjudication |
Complex transaction with disputed stamp duty rate | The collector determines which rate applies and certifies the document |
An old document with no stamp duty paid is being produced in court | The court may refer to the Collector for adjudication before admitting as evidence |
Partition deed, settlement deed with disputed valuation | The value of shares being split is disputed; the Collector adjudicates |
