Here is what it does, and what it does not.
What the EC Is
Issued by the Sub-Registrar's office, the EC records the registered transactions affecting a property over a stated period: sales, mortgages, gifts and releases. Ask for an EC covering as long a period as possible, ideally thirty years or more, so the full registered history is visible.
What the EC Shows
It reveals whether the property has changed hands, whether it has been mortgaged, and whether those mortgages have been released. A clean EC over a long period is reassuring. An EC showing a mortgage with no release deed, or an unexplained gap, is a warning that needs to be understood before you buy.
What the EC Does Not Show
This is the critical part. The EC records only what was registered. It does not tell you whether those transactions were legally valid. It does not reveal unregistered claims, disputes or defects in the underlying title. It does not confirm the boundaries or the extent, and it does not tell you whether the land is prohibited under 22A or sits within a buffer zone. A clean EC is not proof of clear title. It is one piece of the picture.
How to Read It Properly
The EC should be read alongside the chain of title documents, the patta and adangal, and the survey records. Every entry in the EC should correspond to a document you can see and trace. When the EC, the deeds and the revenue records all tell one consistent story, you have real comfort. When they do not, the EC alone will not protect you.
Obtain the EC in every case, but do not stop there. The most expensive property mistakes are made by buyers who saw a clean encumbrance certificate and assumed the title was safe. The EC tells you what was registered. A proper title check tells you whether what was registered was sound.
