A Special Power of Attorney (SPA), also called a Limited Power of Attorney, is a written instrument by which the Principal authorises an Agent to carry out one specific act or transaction on their behalf. The moment that act is completed, the SPA automatically comes to an end.
Like all PoAs, an SPA operates on the law of agency under Chapter X of the Indian Contract Act 1872, and the term Power of Attorney is defined under Section 1A of the Powers of Attorney Act 1882. What sets the Special PoA apart is its narrow, single-purpose scope. It grants exactly the authority needed for one task and nothing more, which makes it the safest and most common PoA type in everyday use.
A Special PoA is used for a single property sale, one court appearance, signing a specific set of documents, completing one bank transaction, registering one vehicle sale, or representing the principal in one specific dealing. Because it dies with the act, an SPA limits the agent's exposure window and is far harder to misuse than a broad General PoA.
For property transactions, the Suraj Lamp ruling (2011) is just as relevant to a Special PoA: the PoA does not transfer ownership. It only authorises the agent to execute the Sale Deed. Title still passes through the registered deed itself, never through the PoA. A Special PoA for a property sale must be registered under Section 17 of the Registration Act 1908.
Governing Law: Powers of Attorney Act 1882 (Section 1A defines PoA), Indian Contract Act 1872 (Chapter X, Law of Agency; Section 202 for irrevocable PoA coupled with interest), Indian Stamp Act 1899 (state-wise stamp duty), Registration Act 1908 (Section 17 mandatory registration for property PoAs), and Indian Evidence Act 1872 (Section 85 presumption of authenticity for notarised PoAs).
