The Uniform Commercial Code (UCC) provides a basic framework for commercial transactions. It aims to promote commerce by establishing guidelines for parties involved. The UCC covers important areas like contracts, sales, leases, and secured transactions. It allows parties to vary certain provisions by agreement and must be interpreted liberally. Obligations include acting in good faith, within a reasonable time period, and according to commercial practices. The UCC governs contracts for goods and sales, and provides remedies for issues like non-payment or defective goods. It also addresses secured transactions through security interests in property.
