The Addendum To Purchase Contract is a crucial legal instrument in Hong Kong's business environment, used when parties need to modify an existing purchase agreement without creating an entirely new contract. This document type is particularly relevant in dynamic business relationships where terms, prices, specifications, or delivery schedules require adjustment. Governed by Hong Kong law, including the Contract and Rights of Third Parties Ordinance (Cap. 623) and Sale of Goods Ordinance (Cap. 26), it provides a formal mechanism to document changes while preserving the original contract's framework. Common scenarios for its use include price adjustments, specification changes, timeline modifications, or addressing unforeseen circumstances that affect the original agreement's execution.
