Why Delhi’s encumbrance certificate is not a Tamil Nadu-style EC
In the southern states the EC is a by-product of how registration offices index their records. Tamil Nadu’s registration department, for instance, issues Form 15, which lists every registered transaction — sale, mortgage, gift, partition, lease — on a survey number for the period asked, and Form 16, a nil certificate where there is none; its records from 1975 onward can be viewed on the TNREGINET portal.
Delhi’s sub-registrar records have historically been searched mainly by party name, deed number and date, not as a property-wise ledger. The Registration Act, 1908 still governs: under Section 57, Book No. 1 (non-testamentary documents relating to immovable property, which is where sale deeds and registered mortgages sit) and its index are open to inspection by any person on payment of the fee, and the registering officer gives certified copies of entries. Delhi gives you that right to inspect and copy; it does not compile the result into a certificate for you.
Two recent changes matter. First, Delhi moved registration onto the central National Generic Document Registration System (NGDRS); the Lieutenant Governor’s office said in August 2024 it was in use across all of Delhi’s then 22 sub-registrar offices, with documents retrievable by deed number, PAN or property number (reported by The Tribune). Delhi raised its sub-registrar offices to 39 in September 2026. Second, the Revenue Department’s registration information page now lists an “Encumbrance Search”, e-search modules for documents registered before 1993 and from 2002 onward, a DORIS deed-document search and a DORIS “prohibited property” list, and states that there is no fee for searching details of past registrations. They are a useful first pass, but older coverage is patchy and no search result carries the weight of a certified copy.
The one gap no registry search closes
The most common home loan in India is a mortgage by deposit of title deeds (Section 58(f) of the Transfer of Property Act). The owner hands the original sale deed to the bank; nothing is registered with the sub-registrar. A Delhi search — and, for the same reason, a southern-state EC — will show that floor as clean. That mortgage shows up only in the lender’s filing with CERSAI, or in the fact that the seller cannot produce the original deed.
