In the United Arab Emirates(UAE), a Special Power of Attorney (POA) is a legal document that grants specific and limited powers to an appointed individual (the attorney or agent) to act on behalf of the principal (the person granting the power). Unlike a General Power of Attorney, which provides broad and comprehensive authority, a Special Power of Attorney restricts the agent's powers to a particular purpose or specific transactions.

A Special Power of Attorney is designed for a specific and limited purpose or transaction. The powers granted are defined in the document and are typically related to a particular legal, financial, or personal matter. The document explicitly outlines the powers delegated to the agent. These powers can include, but are not limited to, signing contracts, conducting financial transactions, representing the principal in legal matters, or handling specific business affairs.

The Special Power of Attorney may specify a duration for which it is valid. It could be a one-time use for a specific transaction or have a defined time frame during which the agent can exercise the delegated powers.

A Special Power of Attorney may require additional documentation and legalization of documents as needed depending on the kind of POA required. 

It's important for individuals considering a Special Power of Attorney in the UAE to seek legal advice to ensure that the document is properly drafted, complies with local laws, and meets their specific needs. Consulting with legal professionals familiar with the legal requirements can help ensure that the Special Power of Attorney is valid and enforceable.
