A sale deed may mention a Survey Number, while the Patta shows a sub-division number. An urban property may instead have a Town Survey Number (TS No.), while a plotted development has a Plot Number and the completed building has a Door Number.

These numbers are not interchangeable.

Each one is created for a different purpose and helps identify the property at a different level. Understanding the difference can make it easier for buyers and landowners to read property documents and carry out basic due diligence.

The Simple Way to Understand Property Numbers

Property identification numbers can broadly be grouped according to their purpose:

1. Land survey and revenue identification
2. Revenue account and ownership-related records
3. Planning and layout identification
4. Local body and building identification
5. Apartment-specific identification

Let us look at each group.

1. Land Survey and Revenue Identification Numbers

These numbers are primarily used to identify the actual parcel of land in government survey and revenue records.

Survey Number (S.No.)

A Survey Number, commonly written as S.No., identifies a parcel of land in survey and revenue records.

For example:

Survey No. 120

A large area of land may originally be recorded under one Survey Number.

Survey Numbers are particularly common in revenue villages and areas covered by the regular land survey system.

Where can you find the Survey Number?

A Survey Number may be found in:

• Sale Deed
• Patta
• Revenue records
• FMB Sketch
• Encumbrance Certificate
• Parent documents
• Government land records

However, buyers should not rely only on the Survey Number. It is important to check whether the land has subsequently been subdivided.

Sub-Division Number

When a larger Survey Number is divided into smaller land parcels, the government may assign sub-division numbers.

For example:

Original Survey No.: 120

After subdivision, the records may contain references such as:

• Survey No. 120/1A
• Survey No. 120/1B
• Survey No. 120/2

The sub-division reference helps identify the exact portion of the larger original Survey Number.

Why is this important?

A buyer may find that an old document refers only to Survey No. 120, while a recent Patta refers to a more specific sub-division.

Therefore, property verification may require checking whether the survey number in older title documents correctly corresponds to the current sub-division number.

Where can you find it?

• Patta
• Sale Deed
• FMB Sketch
• Revenue records
• Property title documents

RS Number (R.S. No.)

RS No. is commonly associated with a re-survey or revised survey reference used in land and revenue records. When an area is surveyed again or its survey records are reorganised, land parcels may be assigned revised or re-survey numbers.

For eample:

R.S. No. 125/3A

An RS Number should be verified with the relevant revenue records to understand its relationship with any older Survey Number.

Where can you find it?

Depending on the locality and applicable survey system, it may appear in:

• Sale Deed
• Patta
• Revenue records
• Land survey records
• Older and newer title documents

Important point for buyers

Do not assume that an RS Number and an old Survey Number automatically refer to the same land merely because they appear similar.

Where older and newer property documents contain different survey references, the correlation should be verified using the relevant official land records.

TS Number (T.S. No.) – Town Survey Number

A TS Number generally means Town Survey Number.

It is used to identify land parcels in areas covered by the town survey system, particularly urban and town areas.

For example:

TS No. 45/2

Instead of a conventional Survey Number used in a revenue village, an urban property may be identified through a Town Survey Number.

In some documents, additional references such as Ward and Block Numbers may also appear along with the TS Number.

For example:

Ward No. 10, Block No. 5, TS No. 45/2

Where can you find it?

• Sale Deed
• Town Survey records
• Patta or land records, where applicable
• Urban property documents
• Government survey records

2. Revenue Account and Land Record Identification

These numbers do not necessarily identify the physical land parcel in the same way as a Survey Number.

Instead, they are connected with revenue records and government land accounts.

Patta Number

A Patta Number identifies a Patta or revenue account record.

For example:

Patta No. 1234

A Patta may contain details such as:

• Name of the recorded pattadar
• Survey Number
• Sub-division Number
• Extent of land
• Classification of land

Where can you find the Patta Number?

• Patta document
• Government land records
• Revenue Department records
• Sometimes in the Sale Deed

3. Planning and Layout Identification Numbers

Once a large parcel of land is developed into a plotted layout, additional numbers may be created to identify individual plots and the relevant planning approval.

Plot Number

A Plot Number identifies an individual plot within a layout.

For example:

Plot No. 15

A larger Survey Number may be developed into multiple plots.

For example:

Survey No. 120

may contain:

• Plot No. 1
• Plot No. 2
• Plot No. 3
• Plot No. 15

An important difference to be noted is that Plot No. 15 alone does not uniquely identify a property because there can be many Plot No. 15s in different layouts and locations.

The complete property description should also identify details such as:

• Layout name
• Survey Number
• Village
• Taluk
• District

Where can you find it?

• Sale Deed
• Approved layout plan
• Planning approval documents
• Developer documents

Layout Approval Number

A layout may also have an approval reference or approval number issued by the competent planning authority.

This number identifies the approval granted to the layout or development, rather than replacing the Survey Number or Plot Number.

Where can you find it?

• Approved layout plan
• Planning approval documents
• Developer documents
• Property records referring to the approved layout

Why is it important?

A Plot Number may tell you which plot you are looking at.

The underlying Survey Number helps identify the original land.

The layout approval reference helps establish which planning approval applies to the layout.

These references may therefore need to be examined together during property due diligence.

4. Local Body and Building Identification Numbers

Once land is developed and a building is constructed, local bodies may use separate identification numbers for administration and taxation.

Ward Number

A Ward Number identifies the larger administrative area in which the property is located.

For example:

Ward No. 12

A Ward Number identifies the administrative division of a Corporation, Municipality or other local body.

For example, the Greater Chennai Corporation is divided into multiple administrative wards. A property may fall under Ward No. 12 of the Corporation. Ward No. 12 falls under Zone 1 – Thiruvottiyur.

Where can you find it?

• Property tax records
• Local body records
• Municipal or Corporation documents
• Certain urban land records

Ward boundaries can also change following administrative or electoral delimitation.

Block Number

A Block Number may be used as part of a larger survey or administrative identification system.

It can be particularly useful in town survey records.

For example:

Ward No. 12
Block No. 5
TS No. 45

Together, these references help locate the property within the relevant town survey system.

Where can you find it?

• Town Survey records
• Urban land records
• Sale Deeds where applicable

Door Number

A Door Number identifies a particular building or premises.

For example:

Door No. 25, Anna Street

It is mainly an address and local administration identifier.

Where can you find it?

• Property tax receipt
• Electricity connection records
• Water and sewerage records
• Local body records
• Sale Deed

Important point

A Door Number is not a substitute for a Survey Number or TS Number when verifying the underlying land.

Door Numbers can also change due to renumbering by local authorities.

Property Tax Assessment Number

Local bodies may assign a separate Property Tax Assessment Number or similar reference for tax administration.

This is primarily used for:

• Property tax assessment
• Tax payment
• Local body records

Where can you find it?

• Property tax receipts
• Corporation or Municipality records
• Local body property databases

5. Apartment and Building Identification

Apartment properties involve another set of identifiers because the buyer is purchasing a specific unit along with a share in the underlying land.

Flat Number

The Flat Number identifies the particular apartment unit.

For example:

Flat No. B-302

This identifies the apartment within the building.

It does not independently identify the underlying land parcel.

The land should still be connected to the relevant:

• Survey Number or TS Number
• Patta and land records, where applicable
• Parent documents

UDS – Undivided Share of Land

UDS means Undivided Share of Land.

This is not an identification number, but it is one of the most important property details for apartment buyers.

For example:

UDS: 500 sq. ft.

An apartment owner generally owns a specific apartment along with a proportionate undivided share in the underlying land.

Therefore, an apartment sale document may contain several different references:

• Flat Number
• Survey Number or TS Number
• Extent of total land
• UDS

Each of these identifies a different aspect of the property.

How the Numbers Work Together

A plotted property may be identified through multiple levels.

For example:

Survey No. 120/3A → Approved Layout → Plot No. 15

An urban property may be described as:

Ward No. 10 → Block No. 5 → TS No. 45/2 → Door No. 25

An apartment may involve:

Survey/TS Number → Total Land → Building → Flat Number → UDS

This is why buyers should avoid checking only one number in isolation.

The Difference

The Most Important Difference to Remember

The easiest way to understand these numbers is to ask one question:

What exactly is this number identifying?

• Survey No. / TS No. / RS No. → Identifies the land under the applicable survey system.
• Sub-division No. → Identifies a specific portion of a larger Survey Number.
• Patta No. → Identifies the relevant revenue record or account.
• Plot No. → Identifies a plot within a particular layout.
• Layout Approval No. → Identifies the planning approval for the layout.
• Ward and Block Numbers → Help identify the larger administrative or town survey area.
• Door No. → Identifies the building or premises.
• Assessment No. → Identifies the property tax account.
• Flat No. → Identifies the apartment unit.
• UDS → Identifies the apartment owner’s proportionate share in the underlying land.

Buyers Should Check The Numbers

A property can have several numbers because the same property is recorded by different government departments and authorities for different purposes.

The key is to establish a clear connection between the different records:

Title Document → Survey/TS/RS Reference → Current Land Record → Approved Layout or Building → Physical Property

When these references do not match, the discrepancy should be examined before proceeding with a property transaction.

Understanding these numbers may seem technical, but they form an important part of basic property due diligence. Knowing what each number identifies can help buyers ask the right questions and better understand whether the documents they are examining actually relate to the property they intend to purchase.

• Sale deeds
• Partition deeds
• Gift deeds
• Settlement deeds
• Ancestral documents
• All prior title transfer deeds forming the “title chain”

If the name of the owner or their parent (father/mother) appears incorrectly or inconsistently across these documents, it causes serious complications in Patta transfer, property registration, inheritance, bank loans, and future transactions.

📌 Understanding Name Mismatch in Property Parent Documents

Name mismatch occurs when the same person’s name appears differently across documents.
Example:

• “R. Muthusamy” in Aadhaar
• “Muthu Swamy” in parent deed
• “Muthuswamy Ramasamy” in Patta

In property law, such variations are not treated lightly — because the burden of proof falls on the heir/owner to establish that all variations refer to one individual.

⚠️ How Name Mismatch Affects Property Transactions

A mismatch can lead to:

• Rejection of Patta transfer requests
• Delays or refusal during property registration
• Objections from Sub-Registrar offices
• Loan/valuation rejection from banks
• Legal-heir disputes
• Delay in selling or partitioning the property

This makes name correction a critical early step in the property documentation process.

📏 Use Verified.RealEstate Before Starting Legal Correction

Before beginning affidavits, Gazette, or court procedures, it is wise to verify the official government records.

✔ Use VerifyMyLand

A complete due-diligence tool that extracts:

• Current owner name
• EC history
• Survey number accuracy
• FMB boundaries
• Legal flags & risks
• Zone & regulatory details

This quickly tells you whether the mismatch is only in your documents or also appears in government systems.

✔ Use Find Property Owner by Address

This helps you check the official name currently recorded in government-linked datasets — useful when older documents show variations.

These tools help you decide whether you need affidavit correction only, or a deeper legal process.

🧩 Correct Procedure to Fix Name Mismatch (Complainant / Plaintiff Approach)

1. Consult a Qualified Property Lawyer

This is the most important step.
A lawyer will:

• Assess seriousness of mismatch
• Decide if affidavit alone is enough
• Advise on Gazette or declaratory suit
• Guide you with the correct documentation

2. Draft a Comprehensive Affidavit

Prepare a detailed “One and the Same Person” affidavit that includes:

• All name variations
• Reason for mismatch
• Clear declaration of identity
• Supporting document references

Get it notarized. This is the first layer of proof.

3. Gazette Publication (Official Name Clarification)

Apply to the Department of Publication (Govt of India) to publish your name clarification.

Gazette entry becomes permanent government evidence that all name variations refer to the same individual.

This is particularly important for:

• Inherited land
• Ancestral property
• Old parent documents
• Legal heir mutations

4. File a Declaratory Suit (Civil Court)

For property matters, the strongest and most legally binding solution is obtaining a declaratory decree.

Under Section 34, Specific Relief Act, the court can declare:

“All name variations refer to the same person.”

A court decree is accepted by:

• Sub-Registrar
• Tahsildar / RDO
• Banks
• Legal heirs
• Buyers
• Patta / Chitta systems

You should do this when:

• Parent deed has huge mismatch
• Original seller is dead (rectification deed impossible)
• Multiple heirs involved
• Mutation is rejected
• Banks demand proof
• Documents are 20–40 years old

🧑‍⚖️ If You Are the Victim / Affected Person

You must:

• Start early — before applying for Patta or sale
• Collect all identity proofs
• Gather parent documents
• Involve family if multiple signatures needed
• Use Verified.RealEstate tools to check official records
• Proceed to affidavit → Gazette → Court decree with lawyer guidance

This ensures smooth future property transactions.

🛠️ How Verified.RealEstate Helps in Documentation

During correction, you may need:

• Certified EC copies
• Certified copies of old deeds
• Historical EC
• Boundary/FMB verification

These are available through Verified.RealEstate’s document services (Certified EC, Certified Copy Title, Legal Assistance).
Using such services ensures that your legal affidavit and court submission are backed by correct records.

✔️ Final Outcome After Correction

Once affidavit + Gazette + court decree are done, you can:

• Update Patta
• Correct name references in parent documents (via rectification deed if possible)
• Proceed with registration
• Apply for legal heir mutation
• Ensure clean, marketable title

Consistency across all property records protects your ownership rights and future transactions.

1. What Is a Sub-Registrar Office (SRO)?

The Sub-Registrar Office, abbreviated as SRO, is a government institution responsible for the registration of properties, maintaining official records, and overseeing legal compliance within its jurisdiction. SROs operate under the Registration Department of the respective State Government.

2. Functions and Responsibilities of an SRO

The key responsibilities of the Sub-Registrar Office include:

• Property Registration:
  Facilitates official registration of property documents such as sale deeds, lease agreements, mortgages, and gift deeds.
• Maintenance of Records:
  Maintains detailed records of all property transactions within its jurisdiction, which are crucial for verifying property ownership and history.
• Issuing Encumbrance Certificates (EC):
  An EC certifies whether a property is free from legal liabilities or pending loans. It’s a critical document in any property transaction.
• Collection of Stamp Duty and Registration Fees:
  SRO collects mandatory government fees during property registrations.
• Resolution of Disputes:
  Assists in the resolution of disputes related to property registration, authenticity of documents, or claims to ownership.

3. When Would You Visit an SRO?

• Buying or selling property
• Transferring property ownership
• Obtaining property documents (e.g., certified copies of sale deeds)
• Applying for an Encumbrance Certificate
• Registering agreements such as lease agreements or mortgages

3. How to Find Your SRO?

1. Purpose of a Rectification Deed

The main purpose of a rectification deed is to amend errors found in registered documents. These errors could range from incorrect names, addresses, and boundary details to mistakes that affect the legal ownership of a property.

2. Applicable for Various Documents

A rectification deed can be used to correct mistakes in a variety of legal documents, including:

• Sale Deeds
• Settlement Deeds
• Partition Deeds
• Wills
• Power of Attorney
• Mortgages
• Release Deeds
• Agreements

3. Types of Rectification Deeds

There are two main types of rectification deeds:

• Simple Rectification Deed: For minor corrections, such as names, addresses, or boundary errors.
• Rectification Deed with Change in Ownership: For errors that impact the property’s ownership or legal rights.

4. Minor Errors

Errors such as misspelled names, incorrect town names, or small mistakes in boundary descriptions fall under minor errors and can be corrected easily with a simple rectification deed.

5. Name Mismatch

If there is a mismatch between the name on the property deed and the name on the patta (land record), a rectification deed can easily correct this issue, which otherwise could cause hesitation in proceeding with the transaction.

6. Common Errors

Some of the common mistakes that require a rectification deed include incorrect survey numbers, initial letters, wrong door numbers, or mistakes in father’s names. These errors are frequent and are typically resolved through simple rectification deeds.

7. Boundary and Utility Errors

Sometimes, property deeds may include errors regarding plot boundaries, electricity connection numbers, or street names. These issues can also be corrected using a rectification deed without altering the ownership rights.

8. Errors Affecting Ownership

If significant errors, such as incorrect acreage (e.g., recording 2 acres instead of 1 acre), are present, they require a rectification deed that involves change in ownership. This type of correction involves updating the correct market value and paying any necessary fees.

9. Market Value Consideration

When correcting errors related to the property’s size or value, the market value must be updated in the rectification deed. This ensures that all property records reflect the accurate details.

10. Stamp Duty

If the correction involves changing the property size or value, the stamp duty paid originally cannot be reclaimed. The correction will reflect the accurate size, but no refunds on previous stamp duties will be issued.

11. If the Seller is Deceased

If the seller has passed away, the legal heirs can file the rectification deed to correct any mistakes in the property documents.

12. No Legal Heirs

If there are no immediate legal heirs, the second or third-degree relatives can file the rectification deed. If no heirs are available, the matter must be resolved through a court order.

13. Seller Refuses to Correct

If the seller refuses to cooperate in filing the rectification deed, the buyer can take legal action through the courts to enforce the correction.

14. New Sale Deed Required

In cases of more significant errors, such as incorrect survey numbers or grossly incorrect property measurements, a new sale deed may be required instead of a rectification deed.

15. Self-Corrections Prohibited

Attempting to self-correct a registered deed by using white-out, making handwritten changes, or altering the document after registration is illegal. These corrections will not be recognized by the Registrar’s Office.

16. Post-registration Corrections

If an error, such as an incorrect plot number, is corrected after registration without going through the proper legal process, the incorrect information will remain in the official records, potentially leading to future disputes.

17. Legal Consequences of Self-Corrections

Any unauthorized, manual changes to a deed are considered illegal and can render the document void in court. Always file a rectification deed to make legal corrections.

18. Signed Corrections

If there are any amendments to key terms or conditions, both parties must sign the corrected document to make it legally valid.

19. Court Considerations

If the error affects key information such as property description or survey numbers, it is essential to go through proper legal channels to correct the deed. Failing to do so can lead to the court deeming the document invalid.

20. Conclusion

A rectification deed ensures that property documents are accurate and legally binding. Always consult with a legal professional when errors are found to avoid costly disputes and complications later on.
