Why you need it

When you need it

For adding or clarifying terms to an already-signed agreement to sell, without rewriting it. Identify the original agreement precisely, list clauses affected, state the supplementary wording, and set a priority rule so both instruments read together. If it touches possession, registration or consideration, assess this document's own stamp/registration treatment rather than assuming the original formality covers it. Gives one traceable record of the exact change, instead of ambiguous WhatsApp/email amendments.

What follows is written for Punjab and Chandigarh. It states the position there rather than describing how it varies, so the amounts below are the ones that apply — worth confirming at the sub-registrar’s office, because rates change. If the property is anywhere else in India, none of this is yours.

Stamp duty

Chargeable as an agreement not otherwise provided for (Art.5, Sch.I-A, Punjab/Chandigarh) — doesn't re-stamp the principal agreement. Raising earnest money under a 5%-duty Chandigarh Item-22 agreement: check the increase's duty with the Sub-Registrar; giving the buyer possession: the Collector may treat it as a conveyance. Stamp at signing (s.17) — unstamped, inadmissible until duty+penalty paid (s.35).

Registration

Not registrable merely for earnest money. But a s.53A (TP Act) contract to transfer for consideration IS compulsory under Registration Act s.17(1A); RERA s.13 may also apply.

Notarisation

Doesn't substitute for compulsory registration or create enforceability where none exists.

Witnesses

Two witnesses are recommended as execution evidence for substantial agreements; doesn’t replace mandatory registration.
