This document provides an overview of key concepts in the Indian Sale of Goods Act of 1930. It defines a contract of sale as one where the seller transfers property in goods to the buyer for a price. Goods are defined as movable property excluding money and actionable claims. A sale involves immediate transfer of ownership, while an agreement to sell involves future transfer. Conditions allow contract termination for breach, while warranties only allow damages claims. Implied conditions and warranties also exist. Caveat emptor generally applies, with exceptions for misrepresentation, latent defects, and implied terms. The timing of property transfer impacts risk and third party actions. Unpaid sellers have rights against goods and buyers personally.
