Encumbrance certificate: how to get one, and how to read it

The EC is the document that reveals a mortgage. It is also the document people most often misread — because “nil encumbrance” sounds far more final than it is.

What is an encumbrance certificate?

An encumbrance certificate is a list of the transactions registered against a property over a period you specify. An encumbrance is any claim or liability attached to the land — a mortgage, a sale, a gift, a partition, a court attachment — so the EC is where you find out whether somebody other than the seller has a call on the property.

In Tamil Nadu it comes from the Registration Department, through tnreginet.gov.in. That is a different department and a different portal from the one holding patta and chitta, which is the single most common wrong turn here — see the patta and chitta guide if you have been searching the wrong site.

How to get an EC

There are two quite different things called an EC, and confusing them wastes either your money or your time.

Use the free view first. If what you see is clean and you decide to proceed, obtain the certified copy before any money moves.

To search, you will need:

1. The zone, district and sub-registrar office the property falls under.
2. The village, and the survey number with its subdivision — 123/2B is different land from 123.
3. A period, as a start and end date. This is a decision, not a formality — see below.

Government portals are redesigned without notice, so treat that as the shape of the task rather than a fixed sequence of clicks. The particulars it asks for have been stable for years.

How to read the certificate

An EC is a table, one row per registered transaction, in date order. The columns vary in presentation but carry the same things:

• Date of execution and registration — when the deed was signed, and when it reached the registry. A long gap between the two is worth a question.
• Nature of the document — sale, mortgage, release, settlement, gift, partition, lease, attachment. This is the column that matters most.
• Executant and claimant — who transferred, and who received. Read these down the page: the claimant of one sale should be the executant of the next.
• Survey number and extent — confirm every row is actually about your land.
• Consideration value — the amount recorded.
• Document number and year — the reference for ordering a certified copy of that specific deed.

Read the rows as a story rather than a list. Ownership should pass cleanly from one party to the next. A name that appears from nowhere, a settlement or gift deed you were not told about, or a partition that splits the extent, all change who is entitled to sell.

What a clean EC still does not tell you

This is where buyers get hurt, because a nil certificate feels conclusive and is not.

• Unregistered transactions. An EC only ever sees documents that were registered. Agreements to sell, many short leases, and informal family arrangements commonly are not.
• The wrong period. A thirteen-year EC cannot show an eighteen-year-old mortgage that was never discharged.
• The wrong office or description. A transaction registered at a different sub-registrar office, or against a differently worded property description, will not surface. A mistyped survey number returns a perfectly clean certificate for land that is not yours.
• Litigation. A pending suit does not appear unless something about it was registered.
• Dues. Property tax, water, sewerage and electricity arrears are not encumbrances in this sense and never appear.

How many years should you ask for?

Thirteen years is the common request and a reasonable floor. Thirty years is what most banks require before sanctioning a loan, and it is the better choice when you are buying rather than merely curious — it reaches back far enough to expose an old undischarged mortgage or a break in the chain of ownership that a shorter search would step over.

If a seller offers you an EC they obtained themselves, look at the period before you look at the result. A clean certificate covering a conveniently short window is not reassurance.

What to check it against

An EC on its own settles very little. It becomes useful when it agrees — or fails to agree — with everything else:

• The sale deed and the parent documents: does the chain in the EC match the chain in the deeds?
• The patta: does the person the revenue record names line up with the last claimant in the EC? (Patta and chitta, explained.)
• The FMB sketch and extent: is every row about the same piece of land?
