For a new apartment, these earlier documents mainly relate to the land on which the project was constructed.

What Is a Mother Deed?

A mother deed generally means the root or earliest important document from which the property’s ownership history can be traced.

It may be a:

Sale deed, gift deed, settlement deed, partition deed, release deed, exchange deed, government grant, Inam grant, trust or endowment deed, court decree, or a will supported by the required succession documents.

Therefore, a mother deed is not always a sale deed. Its nature depends on how the earlier owner acquired the property.

What Is a Parent Document?

A parent document is an earlier title document supporting the present owner’s ownership. The latest document through which the current seller acquired the property is commonly called the immediate parent document.

For example:

• 1970 – Government grants the land to Kumar
• 1982 – Kumar partitions it among his children
• 1995 – One child sells it to Ravi
• 2010 – Ravi gifts it to his daughter
• 2024 – The daughter sells it to a builder

Here, the 1970 government grant may be the root or mother document. The partition deed, sale deeds and gift deed are successive parent documents. The builder’s 2024 sale deed is the immediate parent document.

Together, these documents form the chain of title.

Could Someone Have Owned the Property Before the Mother Deed?

Yes. Calling a document the “mother deed” does not necessarily mean that nobody owned the property before it was executed.

For example, a 1995 sale deed may explain that the seller obtained the property through an earlier partition, inheritance, grant or settlement. The details are usually found in the document’s ownership-history or recital section.

Those earlier documents may also need to be obtained and examined. The purpose is not merely to identify one document as the mother deed. The real objective is to establish a continuous and legally valid ownership chain without unexplained gaps.

Can Parent Documents Reveal a Religious or Charitable Donation?

Yes. Parent documents may reveal that the land was donated, granted or permanently dedicated to:

• A temple, deity or mutt
• A church, diocese or religious society
• A mosque or Wakf
• A charitable trust
• A school or hospital
• A religious festival or daily worship
• Another public or charitable purpose

The relevant document may be described as a gift deed, settlement deed, trust deed, endowment deed, Inam grant, Wakf deed or government grant.

What Should Buyers Look for?

The document should be checked for the following details:

Name of the Beneficiary

The land may have been transferred to a named temple, deity, trustee, religious institution, church, mosque, Wakf or charitable trust.

In some cases, a Hindu temple property may stand in the name of the deity represented by its trustee or executive officer.

Purpose of the Donation

Look for expressions such as:

• Donated to the temple
• Dedicated permanently
• For religious or charitable purposes
• For conducting daily pooja
• For lighting temple lamps
• For conducting annual festivals
• Devadayam
• Dharmadayam or Dharmam
• Service Inam
• Kattalai land
• Wakf property

Restrictions on Transfer

The original deed may state that:

• The property must not be sold
• Only the income from the property may be used
• The land must be used for a particular religious purpose
• The trustee can manage but cannot personally own it
• A sale requires approval from the relevant authority

Property Description

The survey number, subdivision number, extent and boundaries in the donation or endowment document must match the property now being sold.

A similar village name or temple name is not enough to establish that both documents relate to the same land.

Why the Latest Sale Deed May Not Reveal the Problem

Suppose land was donated to a temple in 1940 but was wrongly treated as private property and sold in 1995. The 1995 sale deed may omit or incorrectly describe the earlier dedication.

Therefore, the latest sale deed, patta or Encumbrance Certificate cannot be accepted alone as final proof of private ownership. The complete document chain must be traced backwards through the earlier document numbers mentioned in each deed.

Does a Religious Condition Always Make the Temple the Owner?

Not necessarily.

A document may require a private owner to use part of the property’s income for temple pooja or a festival. This may create an obligation or charge without transferring ownership of the land itself.

But if the property was permanently dedicated or transferred to a deity, temple or religious institution, it may no longer be ordinary private property.

The exact wording of the original document determines whether the institution owns the property or only receives a benefit from it.

Are Parent Documents for the Land or the Apartment?

For a newly constructed apartment, the older parent documents mainly relate to the entire project land because the individual apartment did not exist earlier.

After construction and sale, the apartment buyer receives a registered sale deed covering:

• The individual apartment
• The proportionate Undivided Share of Land or UDS
• Rights in the project’s common areas, subject to the applicable documents

Under Section 17 of the Real Estate (Regulation and Development) Act, the promoter must execute a registered conveyance deed in favour of the allottee along with the proportionate title in the common areas. (RERA Act – Section 17)

When the apartment is later resold, the first buyer’s apartment sale deed becomes the immediate parent document for the next buyer.

Will Every Apartment Buyer Receive the Original Parent Deeds?

Every apartment owner cannot normally hold the same original land documents. Buyers generally receive copies or certified copies for verification.

The common original documents may later be held by the apartment owners’ association or another legally authorised custodian. However, the builder must establish the legal right to develop and sell the property and allow the title documents to be examined.

What New Apartment Buyers Should Verify

Before purchasing, verify the project land’s complete title chain, including the builder’s or landowner’s title deed, Joint Development Agreement and Power of Attorney, patta and survey records, Encumbrance Certificate, land-classification records, religious or charitable claims, court or government proceedings, planning approvals, TNRERA registration, Completion Certificate, mortgage release or lender’s NOC, and the apartment’s correct UDS.

Under Section 55 of the Transfer of Property Act, 1882, the seller must produce title documents in their possession or control for the buyer’s examination. (Transfer of Property Act, 1882 – Section 55)

A new apartment has no previous sale deed, but the land beneath it must have a clear, traceable title history. Obtain certified parent documents and land records, and secure an independent legal title opinion before paying a major advance. Verified.RealEstate provides the checking of the title, land-record, approval and encumbrance checks, including verification of temple, HR&CE, Wakf, religious, charitable or other restricted-property claims.

A major property tax dispute has erupted in Chennai’s Mogappair West, where residents of a large apartment complex have alleged that the Greater Chennai Corporation (GCC) incorrectly recorded the sizes of their flats, resulting in significantly higher property tax assessments.

According to the residents, the discrepancies came to light when homeowners compared their latest property tax assessment notices with the measurements mentioned in their registered sale deeds and builder documents.

The issue affects around 1,840 apartments, with residents estimating that the incorrect assessments are collectively costing them an additional ₹30 lakh every year in property taxes.

Flats Allegedly Measured Much Larger Than Their Actual Size

One of the examples highlighted by residents involved a flat with an actual size of 1,062 sq ft, which was reportedly assessed by the Corporation as 1,498 sq ft.

The recorded area was nearly 41% larger than the actual size of the apartment.

Residents claim that several flats in the complex were similarly overestimated, leading to substantially higher tax demands.

Why Does an Increase in Square Footage Matter?

In Chennai, property tax is calculated based on several factors, including:

• Built-up or plinth area;
• Location of the property;
• Nature of usage (residential or commercial); and
• Classification of the building.

Since the built-up area is one of the primary components in determining the property’s annual value, any increase in the recorded square footage directly increases the tax payable.

Even a few hundred extra square feet reflected in municipal records can substantially increase the annual tax burden on homeowners.

How Did the Discrepancy Come to Light?

Residents reportedly discovered the issue after comparing:

✔ Registered sale deeds

✔ Builder agreements and floor plans

✔ Existing property tax records

✔ Recent assessment notices issued by GCC

The mismatch prompted residents to raise objections with the civic body, arguing that the Corporation’s records did not reflect the actual dimensions of their apartments.

GCC Agrees to Physically Remeasure the Flats

Following complaints and public backlash, the Greater Chennai Corporation has agreed to conduct a physical remeasurement of the properties in the presence of homeowners.

The exercise is expected to:

• Verify the actual built-up area of each flat;
• Correct any erroneous entries in municipal records;
• Revise property tax assessments where necessary; and
• Consider adjustments or refunds if excess tax has already been collected.

The decision has been welcomed by residents, who have been seeking corrections to what they describe as an unjustified increase in their property tax liability.

What Could Have Caused the Error?

While GCC has not publicly disclosed the exact reason behind the discrepancies, experts point to several possible causes:

1. Data Entry Errors

Incorrect information may have been entered during digitisation of property records.

2. Confusion Between Different Area Measurements

There is often confusion between:

• Carpet Area
• Built-up Area
• Super Built-up Area

Recording the wrong type of measurement can significantly alter the tax calculation.

3. Migration of Legacy Records

Errors may have occurred while transferring older records into newer digital assessment systems.

4. Survey and Measurement Mistakes

Incorrect measurements during previous inspections or assessments could also have contributed to the issue.

What Should Property Owners Learn From This?

The Mogappair incident serves as an important reminder for property owners across Chennai to periodically verify their municipal records.

Homeowners should compare the area recorded in their property tax assessment with:

• The registered sale deed;
• Approved building plans;
• Builder documents; and
• Previous assessment records.

Any discrepancy should be immediately brought to the attention of the Corporation to avoid paying excess taxes.

Can Homeowners Challenge Incorrect Property Tax Assessments?

Yes. Property owners can submit representations and supporting documents to the concerned Corporation authorities if they believe their assessments contain errors.

Documents that can help establish the correct area include:

• Registered Sale Deed;
• Approved Building Plan;
• Completion Certificate;
• Previous Property Tax Assessment Orders; and
• Builder’s Allocation Statement.

The Mogappair case demonstrates the importance of maintaining accurate property records and regularly reviewing tax assessments, especially as civic bodies increasingly rely on digitised data.

In many parts of Chennai, apartment residents are facing an unexpected and frustrating issue—no proper water or sewer connections, even years after construction.

The root cause? A major confusion between two similarly named but completely different charges collected by two separate authorities:

• Infrastructure & Amenities (I&A) Charges by Chennai Metropolitan Development Authority
• Infrastructure Development Charges (IDC) by Chennai Metropolitan Water Supply and Sewerage Board

Because both are commonly referred to as “infrastructure charges,” many residents—and even some officials—have misunderstood their purpose.

⚠️ Real Problem: Residents Paying Twice?

A striking case from Tiruvottiyur highlights the issue.

An apartment with over 237 families, built nearly 17 years ago, is still dependent on water tanker lorries and private sewage disposal.

The residents claim:

• Their builder already paid ₹1.05 crore as I&A charges to CMDA during planning approval
• Yet, Metro Water is demanding IDC at ₹320 per sq. ft. before giving connections

Naturally, residents are asking:
“If infrastructure charges were already paid, why should we pay again?”

🧩 The Core Confusion Explained

Let’s break it down clearly.

🏙️ What Are I&A Charges (CMDA)?

I&A charges are collected by CMDA during planning permission approval.

These funds are used for:

• Roads and flyovers
• Parks and public amenities
• Drainage and urban infrastructure

👉 These charges support city-level development, not individual building connections.

💧 What Are IDC Charges (Metro Water)?

IDC is collected by Metro Water when applying for:

• Water supply connection
• Sewer connection

These charges are used for:

• Laying pipelines
• Expanding sewer networks
• Enabling building-level connections

👉 These charges are specific to providing water and sewer access to your property.

🔍 Why This Has Become a Serious Issue

The confusion has led to multiple real-world problems:

❌ 1. Misinformation at Ground Level

In some cases, local engineers reportedly told residents that CMDA has not transferred funds to Metro Water, reinforcing the misunderstanding.

❌ 2. Delayed Water & Sewer Connections

Residents are stuck waiting because they assume no further payment is needed.

❌ 3. Financial Shock for Buyers

Unexpected IDC demands come years after purchase.

❌ 4. Dependence on Tankers

Without connections, buildings rely on:

• Private water tankers
• Costly sewage disposal services

🏢 Not Just One Case — A Citywide Pattern

This issue is not isolated.

In fast-developing areas like OMR:

• Many apartments were built during 2008–09
• At that time, water and sewer infrastructure was not fully developed

Now, residents are facing the consequences:

• Buildings exist
• People live there
• But infrastructure approvals and connections are still incomplete

🧠 Official Clarification (What Authorities Say)

A senior CMDA official clarified:

• I&A charges cannot be transferred to Metro Water
• They are meant for general urban development, not utility connections

Metro Water officials have also acknowledged:

• There is confusion among junior staff and residents
• Awareness needs to be improved

🏠 What Property Buyers Must Learn From This

This situation exposes a major gap in real estate awareness.

Before buying an apartment in Chennai, always verify:

✔️ Whether Metro Water connection is approved
✔️ Whether IDC has been paid
✔️ Availability of sewer network in the area
✔️ Completion Certificate and utility readiness
✔️ Not just CMDA approval—but actual service connections

⚡ The Bigger Insight

Planning approval does NOT guarantee water connection.

Just because a builder paid charges to CMDA doesn’t mean your home will automatically get Metro Water supply.

This gap between approval and actual infrastructure delivery is what’s affecting thousands of residents today.

🔎 How to Stay Safe

To avoid such issues:

• Verify utility connections before purchase
• Don’t rely only on builder claims
• Cross-check approvals with both CMDA and Metro Water
• Use professional due diligence tools and services

🧾 Final Takeaway

The confusion between I&A and IDC charges may sound technical—but its impact is very real.

Families are living without basic water access, despite owning approved apartments.

Until awareness improves and processes become clearer, buyers must take responsibility to verify every layer of approval—not just paperwork, but actual infrastructure readiness.

🧱 What Is Built-up Area?

Built-up Area = Carpet Area + External walls + Balcony + Utility areas

It covers your private unit’s entire built structure, including outer walls and private additions.

👉 Usually, this is 10–20% more than carpet area.

📍Example Continued:
Carpet Area = 600 sq.ft + walls + balcony = 120 sq.ft
➡ Built-up Area = 720 sq.ft

🏢 What Is Super Built-up Area?

Super Built-up = Built-up + Share of common areas like lift, lobby, staircase, and even clubhouse or stilt parking.

⚠ This number is not regulated by RERA and varies between builders.

📍Example:
Built-up Area = 720 sq.ft + Common Area = 180 sq.ft
➡ Super Built-up Area = 900 sq.ft

📐 What Is RERA Carpet Area?

Under RERA, carpet area is clearly defined to exclude balconies and external walls, but include internal walls.

✅ Builders must mention RERA Carpet Area in all agreements.

🧱 What Is Plinth Area?

Plinth Area = Total built-up footprint of your flat measured from the outer wall to outer wall — used mostly for plan approvals and DTCP/CMDA clearance.

It includes walls, ducts, and structural space but excludes shared areas and parking.

🌍 What Is UDS – Undivided Share of Land?

UDS refers to your share in the total land that your apartment building stands on. Higher UDS = more ownership and better resale/development rights.

📌 How it’s calculated:
UDS = (Your flat’s built-up area / Total built-up area of all flats) × Total land area

📍Example:
6 flats of 800 sq.ft on 4800 sq.ft land
➡ Each flat’s UDS = 800 sq.ft

🧮 Bonus: Stamp Duty Implications

Builders often charge based on super built-up area, but stamp duty and registration apply to carpet or built-up area.

📢 What Smart Buyers Always Ask:

• ✅ What is the RERA Carpet Area?
• ✅ What is the Super Built-up Area and Loading %?
• ✅ How much UDS will I own?
• ✅ Is the project CMDA/DTCP approved?
• ✅ Does the plinth area match approved plans?
