In Mumbai, the Land Records Superintendent has implemented a new system to allocate a unique identification number to land parcels known as the CTS Number, which stands for City Title Survey Number. This number is now mandatory for property owners, sellers, and buyers as it plays a crucial role in verifying land ownership details and ensuring transparency in real estate transactions.

In the complex and intricate world of real estate, clarity and transparency are crucial. Whether you are a first-time homebuyer, seasoned investor, or legal consultant, understanding the technical details of property documents can save you time, money, and future legal disputes. One such essential detail is the CTS number of a property.
The CTS number, often seen in official paperwork and municipal records, plays a crucial role in identifying, tracking, and verifying property ownership. Yet, many property owners and buyers remain unaware of what it actually stands for and why it is so important.
This article aims to answer the fundamental question: “What is a CTS number of a property and why is it important?” Through an in-depth explanation, examples, and practical insights, we’ll help you navigate this topic with clarity and confidence.
What is a CTS Number?
CTS Number Full Form
CTS stands for City Survey Number. It is a unique identification number assigned to a land or property by the local municipal authority, particularly in Maharashtra, including cities like Mumbai, Thane, Pune, and Nashik.
This number is used to uniquely identify and catalog a piece of land or property in the city survey records maintained by the land revenue department or municipal corporation.
1.2 Alternative Names of CTS Number
Depending on the state and municipal system, the CTS number may also be known as:
-
Survey Number
-
Dag Number
-
Khata Number
-
Khasra Number
But in cities like Mumbai and Pune, CTS number is the official terminology used.
Where Can You Find the CTS Number of a Property?
The CTS number is usually mentioned in multiple legal and municipal documents, including:
-
Property Tax Receipts
-
Sale Deed
-
7/12 Extract (for land outside city limits)
-
Property Registration Documents
-
Property Mutation Records
-
Municipal Records or Online Property Portals
2.1 How to Search for CTS Number Online (Maharashtra Example)
In Maharashtra, you can find the CTS number of a property through:
-
Municipal websites such as MCGM (Municipal Corporation of Greater Mumbai)
-
MahaBhulekh portal (Maharashtra land records)
-
Local Property Tax Department
You’ll need basic details like the location, ward number, and building name or plot number to conduct a search.
Why is the CTS Number Important?
3.1 Legal Identification of Property
The CTS number ensures that a particular plot or property is legally recognized and registered in the land records. It provides an official trail and acts as a legal ID for that parcel of land.
3.2 Vital for Property Registration
During the registration of property transactions such as buying, selling, mortgaging, or leasing, the CTS number is a mandatory input in government systems. Without this number, registration may be incomplete or rejected.
3.3 Required for Building Permissions
If a landowner wants to construct or redevelop a building, municipal authorities demand the CTS number while issuing permissions, NOCs, and approvals.
3.4 Used in Property Tax Assessment
The property tax amount levied by municipal corporations is linked to the CTS number. Any change in property use (e.g., residential to commercial) must be updated against the corresponding CTS number.
3.5 Prevention of Land Disputes
With a proper CTS number, the chances of land ownership disputes reduce significantly, as the number is unique and reflects in official land records.
3.6 Helpful in Real Estate Due Diligence
Lawyers and real estate consultants check the CTS number to ensure clean title ownership, absence of litigation, and compliance with zoning norms before advising clients on purchase.
CTS Number vs Survey Number – What’s the Difference?
While both numbers serve the purpose of land identification, they are not the same.
Feature | CTS Number | Survey Number |
---|---|---|
Full Form | City Survey Number | Survey Number (Rural) |
Used In | Urban Areas (e.g., Mumbai) | Rural and Semi-urban Areas |
Maintained By | City Survey Department | Talathi or Village Officer |
Purpose | Urban property identification | Agricultural/Non-urban land |
Format | Numeric (e.g., 125/1, 126/B) | Alphanumeric or Numeric |
So, if you’re buying a flat in Mumbai, you’ll need the CTS number. But if it’s a farmland in Maharashtra, you’ll likely need the Survey Number or Gat Number.
Structure and Format of CTS Numbers
CTS numbers are typically alphanumeric, especially in older municipal records. However, modern records often use structured numeric formats. Here’s how they usually appear:
Example Formats:
-
CTS No. 123/1/A – This denotes plot number 123, subdivision 1, sub-subdivision A
-
CTS No. 456/2B – Plot number 456, sub-plot 2B
This hierarchy helps identify divisions of the same property or land when it has been split or developed over time.
What If My Property Has No CTS Number?
This is a common concern, especially in areas undergoing urbanization or redevelopment.
Here’s what you should do:
-
Contact the Municipal Ward Office with your property documents.
-
Apply for a CTS Number allocation, especially if your land has recently been developed.
-
In case of disputes or overlapping surveys, hire a licensed land surveyor to conduct a fresh city survey.
-
Regularize unapproved constructions (if any) through the appropriate municipal channel.
Remember, any delay in regularizing the CTS number may affect your legal rights and property value.
Importance of CTS Number in Redevelopment Projects
With the rise of redevelopment in cities like Mumbai, the CTS number becomes extremely important for:
-
Verifying if the plot is eligible for redevelopment.
-
Coordinating with MHADA, SRA, or MCGM.
-
Acquiring Transfer of Development Rights (TDR).
-
Calculating Floor Space Index (FSI) and area to be redeveloped.
-
Getting project approvals from civic bodies.
Builders and developers always refer to the CTS number before acquiring old buildings for redevelopment to avoid legal and zoning issues.
Common Mistakes Regarding CTS Number
8.1 Confusing CTS Number with Property ID
Property ID is used for tax purposes and is often different from the CTS number. Don’t mix the two while filing taxes or registering your property.
8.2 Ignoring CTS Number in Legal Documents
Never sign a sale deed or lease agreement without verifying the correct CTS number. A mismatch can result in disputes or invalidation.
8.3 Assuming All Properties Have a CTS Number
Not all properties automatically get a CTS number—especially unauthorized constructions or new urban zones. Always verify from municipal records.
Legal and Government Use of CTS Numbers
Various authorities use the CTS number to:
-
Verify property details during mutation and transfer of ownership.
-
Issue Notices of Demolition or Acquisition.
-
Collect property tax.
-
Approve architectural plans and layouts.
-
Maintain digital land records under e-governance systems.
A property without a registered CTS number may be considered illegal or unauthorized in urban planning records.
CTS Number in Property Litigation and Court Cases
In court proceedings related to land disputes, eviction, property possession, or ownership titles, the CTS number becomes a central point of reference. Judges and legal representatives rely on this number to trace municipal and revenue records.
Lawyers typically use the CTS number to:
-
Check encumbrances and liens
-
Identify if land is under acquisition
-
Determine land zoning classification
-
Verify authenticity of ownership claims
Understanding the CTS Number
The CTS Number is a unique identification code assigned to each land parcel in Mumbai. It serves as a reference point for the land’s location and ownership details. This number is generated based on a systematic survey conducted by the city authorities, ensuring accuracy and reliability.
With the CTS Number, property owners, sellers, and buyers can easily access and verify essential information about the land, such as ownership records, property tax details, and any existing encumbrances. This helps in preventing fraudulent transactions and provides a level of trust and security for all parties involved.
Allotment Process
The process of allotting a CTS Number involves a comprehensive survey of the land parcel by the city authorities. The survey includes mapping the boundaries, measuring the area, and documenting other relevant details. Once the survey is completed, the authorities assign a unique CTS Number to the land parcel.
It is important to note that the CTS Number is not randomly assigned. It follows a specific format that includes the ward number, division number, and plot number. This format ensures that each land parcel is uniquely identified and can be easily located on the city’s records.
Importance of the CTS Number
The CTS Number holds significant importance for property owners, sellers, and buyers in Mumbai. Here are some key reasons why it is crucial:
1. Verification of Ownership
By having the CTS Number, property owners can easily verify their ownership details. They can access official records and ensure that their ownership rights are correctly documented. This helps in avoiding disputes and legal complications in the future.
2. Transparency in Real Estate Transactions
For sellers and buyers, the CTS Number provides transparency in real estate transactions. It allows them to check the ownership history, any existing encumbrances, and property tax details. This information helps in making informed decisions and ensures a fair and transparent transaction process.
3. Prevention of Fraudulent Transactions
The CTS Number acts as a safeguard against fraudulent transactions. With access to the land’s ownership details, buyers can verify the authenticity of the seller and ensure that the property is legally owned. This helps in preventing scams and protects the interests of all parties involved.
4. Easy Access to Property Information
Having the CTS Number simplifies the process of accessing property information. Property owners can easily retrieve documents related to their land, such as property tax receipts, building plans, and development permissions. This saves time and effort in dealing with government authorities.
Conclusion: CTS Number is Your Property’s Legal Identity
To summarize, the CTS number of a property is a vital identification tool, particularly in urban cities of Maharashtra. It holds legal, financial, and municipal importance across every stage of property lifecycle—purchase, development, taxation, and resale.
Ignoring or overlooking the CTS number may result in:
-
Registration issues
