Buying Property in Chennai? 12 Essential Documents You Must Check Before You Invest

A practical property due-diligence guide for buyers in Tamil Nadu

Buying a property is one of the biggest financial decisions you may ever make. Whether you are purchasing a residential plot, an independent house, or an apartment in Chennai, the excitement of finding the right property can sometimes overshadow one important responsibility: checking the documents.

A property may look attractive. The location may be excellent. The seller may be trustworthy. The price may seem like a great deal.

But do you know what the property records actually say?

Are you buying from the person who has the legal right to sell? Does the property description match across the documents? Are there mortgages or other registered transactions to investigate? Does the plot or building have the relevant approvals?

These are not questions to leave until after you pay a substantial advance.

At TitleScope, we believe that an informed property decision begins with careful document review. This guide explains the important records you should collect, what each one can help you understand, and why they should be examined together.

1. Sale Deed – Start with the Ownership Documents

The sale deed is one of the most important documents in a property transaction. It records the transfer of the property from the seller to the buyer.

Before proceeding, examine:

  • The name and identity of the seller.
  • The name of the previous purchaser or transferor.
  • The property description and boundaries.
  • Survey number, subdivision number or town survey details, as applicable.
  • Extent of land and measurements.
  • Registration details, including document number, year and Sub-Registrar Office.
  • Whether the document refers to any conditions, rights or restrictions relevant to the transaction.

Important: Do not examine only the latest sale deed. Earlier deeds and other documents in the ownership history may also be necessary to understand how the property came to the present owner.

A registered deed is important evidence, but simply possessing one document does not automatically establish that the seller has an unquestionable title.

2. Parent Documents – Understand the Property’s History

Parent documents help trace the property’s ownership history.

Depending on the property and how it changed hands, these may include:

  • Earlier sale deeds.
  • Partition deeds.
  • Settlement deeds.
  • Gift deeds.
  • Release deeds.
  • Exchange deeds.
  • Court orders or decrees.
  • Inheritance-related documents.
  • Other instruments affecting ownership.

Why are these important?

Imagine that a seller purchased a property in 2018. You should not automatically assume that the 2018 deed answers every ownership question. The earlier ownership and the seller’s right to transfer the property may also need examination.

The relevant period and documents to be examined depend on the property’s history and the legal review required. An advocate should determine the appropriate title-search scope.

3. Encumbrance Certificate (EC) – Check Registered Transactions

An Encumbrance Certificate, commonly called an EC, is an important record to obtain when examining a property.

It can help identify registered transactions relating to the property for the selected search period and search particulars. Depending on the records, these may include sale transactions, mortgages and other registered instruments.

When examining an EC, pay attention to:

  • Whether the property details used for the search are correct.
  • Whether the survey number and subdivision details match.
  • Whether the search period is appropriate.
  • Whether registered mortgages or other entries appear.
  • Whether the names and document references correspond with the documents supplied.
  • Whether any entries need further investigation.

One important point: An EC is not a guarantee that a property has a clear title. It may not reveal every possible claim, dispute, unregistered arrangement or issue outside the records searched.

For that reason, an EC should always be considered alongside the ownership documents and other relevant records.

4. Patta and Revenue Records – Check the Land Details

For properties in Tamil Nadu, revenue records such as Patta, Chitta, A-Register and related records may be relevant, depending on the nature and location of the property.

These records can help examine details such as:

  • Recorded landholder information.
  • Survey number and subdivision.
  • Land classification.
  • Extent and related revenue particulars.
  • Whether the information corresponds with the documents supplied.

For certain properties, an FMB sketch or other survey-related record may also be relevant.

Do not assume that Patta alone proves ownership. Revenue records and registered title documents serve different purposes. A proper review should compare them and identify discrepancies requiring clarification.

5. Layout Approval – Particularly Important When Buying a Plot

If you are purchasing a vacant residential plot, do not rely only on the seller’s statement that it is an approved layout.

Ask for the relevant layout approval documents and examine:

  • Approval number and issuing authority.
  • Approved layout plan.
  • Plot number and location within the layout.
  • Survey numbers covered by the approval.
  • Plot dimensions and extent.
  • Roads and access shown in the approved plan.
  • Open spaces and land reserved for public purposes, where applicable.
  • Whether the plot being sold corresponds to the approved plan.

Also investigate whether the approval is genuine and whether the specific plot is covered by it.

A layout brochure, marketing plan or unofficial drawing is not a substitute for the relevant approval record.

6. Building Plan Approval – Do Not Judge a Building by Its Appearance

When buying an independent house or apartment, examine the relevant planning permission and building approval documents.

Depending on the property, this may involve records issued by CMDA, DTCP or the relevant local planning authority.

Check:

  • Approval number and date.
  • Approved building plan.
  • Property and survey details.
  • Permitted use.
  • Number of floors and units.
  • Whether the constructed building corresponds with the approved plan.
  • Whether later additions or alterations require further approval.
  • Completion or occupancy-related records, where applicable.

A building that looks properly constructed from the outside may still have deviations from the approved plan.

For Chennai properties, the relevant authority and approval process depend on the property’s location and classification.

7. Tamil Nadu RERA – Check Applicable Real Estate Projects

If you are purchasing a flat or unit in a real estate project covered by the Real Estate (Regulation and Development) Act, 2016, check the project’s registration and available disclosures with Tamil Nadu RERA.

Look for:

  • Project registration details.
  • Promoter details.
  • Project location and land particulars.
  • Approved plans and permissions disclosed.
  • Proposed completion information.
  • Project updates and other available disclosures.
  • Any orders or complaints that may be relevant.

Do not rely only on a builder’s advertisement, sales brochure or verbal promise.

Also remember that RERA registration is not a substitute for an independent examination of the property’s title and the buyer’s specific transaction documents.

8. Undivided Share (UDS) – A Critical Check for Apartment Buyers

When purchasing an apartment, you are generally buying more than the physical flat.

The transaction may also include an undivided share of the underlying land, commonly called UDS.

Understand:

  • The UDS stated in the sale deed.
  • The total land extent.
  • The number of flats and relevant allocation details.
  • Whether the UDS figures are consistent across the project documents.
  • Whether the property description correctly identifies the flat and associated land share.

Do not compare apartment prices only by built-up area or carpet area. Understand what land share is being conveyed to you and have the calculation and legal implications checked by an advocate.

9. Property Tax and Utility Records – Check the Practical Details

Property tax, water and electricity records can help you understand the property’s administrative and practical status.

Ask for relevant records, where applicable:

  • Latest property tax receipts.
  • Property tax assessment details.
  • Water and sewerage charges.
  • Electricity service connection details.
  • Maintenance receipts.
  • Outstanding dues or notices.

Check whether the property identifiers, address and owner or occupier details correspond with the transaction documents.

Remember: payment receipts and utility connections are not proof of legal ownership. They are supporting records, not substitutes for title documents.

10. Inheritance, Legal Heirs and Family Rights – Take Extra Care

Properties acquired through inheritance or family arrangements may require additional examination.

For example, ask whether the property came through:

  • Inheritance after the death of an owner.
  • A Will.
  • A family partition.
  • A settlement deed.
  • A release deed.
  • A court order.

Depending on the facts, relevant supporting records may include death certificates, legal heir certificates, Wills, probate-related records where applicable, partition documents and releases.

A person claiming to be the sole owner may not necessarily have the right to sell the entire property without addressing the rights of other persons.

Never proceed merely because one family member says that everyone has agreed. The relevant documents and legal rights must be examined.

11. Boundaries, Measurements and Actual Site – Verify What You Are Buying

Paper records and the actual property should correspond.

Before completing a purchase, consider whether a qualified surveyor should verify:

  • Survey and subdivision numbers.
  • Land extent and measurements.
  • Four boundaries.
  • Access road and pathway.
  • Physical possession.
  • Encroachments or boundary disputes.
  • Differences between the registered description, revenue records and actual site.

For an apartment, also verify the flat number, floor, car-parking arrangement and the relevant common-area details.

A document review cannot replace a physical site inspection or a professional land survey.

12. Agreement for Sale – Read Before You Sign or Pay

The agreement for sale sets out important terms between the buyer and seller.

Before signing, carefully examine:

  • Correct names and identities of the parties.
  • Complete property description.
  • Agreed sale consideration.
  • Advance amount and payment schedule.
  • Time allowed for completion.
  • Responsibility for obtaining documents and approvals.
  • Treatment of existing loans or encumbrances.
  • Conditions for cancellation and refund.
  • Handover and possession terms.
  • Responsibilities for taxes, charges and outstanding dues.

Avoid signing a document simply because the seller or agent says it is a standard format.

Have the agreement and proposed sale deed reviewed by an enrolled advocate before committing to the transaction.

A Practical Checklist Before You Buy

Use this checklist to organise the documents you should request. The exact requirements will vary depending on the property type and its history.

Document or record What it helps examine
Current sale deed Present transaction and property description
Parent documents Ownership history
Encumbrance Certificate Registered entries for the search period
Patta and relevant revenue records Revenue particulars and land details
A-Register / FMB / survey records, where relevant Classification, survey and measurements
Layout approval, for plots Approved layout and plot identity
Building approval and plan Permitted construction
RERA details, where applicable Project registration and disclosures
UDS details, for apartments Land share associated with the flat
Property tax and utility records Supporting administrative and payment details
Inheritance or family documents, where relevant How ownership or rights were acquired
Agreement for sale Transaction conditions and buyer protections

Remember: Collecting documents is only the first step. The important work is checking whether the details agree, identifying missing records and investigating discrepancies.

Five Warning Signs You Should Never Ignore

A property transaction deserves additional investigation if you encounter any of these situations:

1. The seller cannot provide important ownership documents.

A missing document does not automatically mean that the property cannot be purchased, but the reason for its absence and the available supporting evidence must be examined.

2. Property details do not match.

Different survey numbers, extents, boundaries, names or document references across records may require clarification.

3. The EC contains entries that have not been explained.

Do not ignore mortgage entries, registered transactions or other unexplained records. Obtain the relevant documents and investigate them.

4. The seller pressures you to pay immediately.

A genuine transaction should allow reasonable time for document verification and professional advice.

5. The actual building or plot differs from the documents.

Differences in layout, boundaries, construction or permitted use should be investigated before proceeding.

These are warning signs, not automatic conclusions. Each situation needs to be assessed on its own facts.

Why Checking One Document Is Not Enough

Imagine that a buyer receives a sale deed, a Patta and an EC from the seller.

At first glance, everything may appear satisfactory.

But what if:

  • The survey number in one document differs from another?
  • The EC search was conducted using incomplete property particulars?
  • An earlier deed refers to a different extent?
  • The building has alterations that do not correspond with the available approval?
  • The seller’s ownership comes through an inheritance that requires further documents?

This is why property due diligence should involve more than collecting a few photocopies.

The real value lies in comparing records, understanding their limitations and identifying questions that need answers.

How TitleScope Helps Property Buyers

TitleScope provides property document review and due-diligence assistance for buyers in Tamil Nadu.

Our approach is designed to help customers organise their documents, identify inconsistencies and understand what needs further clarification.

Our review process can include:

  1. Document collection: We help organise the property documents supplied by the customer.
  2. Preliminary document checking: Relevant particulars, dates, names, property descriptions and references are examined.
  3. Cross-document comparison: Information across the supplied records is compared to identify apparent differences or missing information.
  4. Review and reporting: Findings, observations, limitations and recommended follow-up questions are organised into a structured report.
  5. Independent legal advice: Where a formal legal title opinion is required, the customer should engage an enrolled advocate independently.

TitleScope’s document review report is not a court order, government certificate, advocate’s legal title opinion or guarantee of clear title. The scope and limitations of every review depend on the documents and information made available.

We believe buyers should understand what has been checked, what has not been checked and what questions remain unanswered before making a major financial commitment.

Before You Pay an Advance, Ask These Questions

  • Have I seen the relevant ownership documents?
  • Has the ownership history been examined?
  • Have I obtained an appropriate EC?
  • Do the survey numbers, extent and boundaries match?
  • Have the relevant revenue records been checked?
  • Are the layout and building approvals applicable to this property?
  • Have I checked RERA details, where applicable?
  • Have I understood the UDS if I am buying an apartment?
  • Have I investigated any unexplained entries or discrepancies?
  • Has an enrolled advocate independently advised me on the legal title and transaction?

If you cannot confidently answer these questions, pause and obtain the necessary clarification before proceeding.
