Amendment
Short answer
An amendment is a written, signed change to an existing contract that modifies, adds or removes specific terms without replacing the whole agreement. Each amendment has its own effective date, and the current position of the contract is the original text combined with every amendment in force.

Amendments, also called addenda, variations or change orders, are how a contract evolves: new prices, an extended term, added services, a revised notice address.
Key characteristics
- Formal requirement. Many contracts say changes only count if written and signed by both parties.
- Scope. An amendment changes only what it says. Everything else in the original continues.
- Precedence. A later amendment normally overrides an earlier or original term on the same point.
- Amend and restate. Replaces the whole agreement with a new consolidated text.
Example
The original contract has a 12-month term at USD 10,000 per year. Amendment 1 extends the term by 12 months. Amendment 2 raises the fee to USD 11,000 from the extension. The current position is a 24-month term, with USD 10,000 for the first year and USD 11,000 for the second.
Why it matters
The signed original rarely shows the true deadlines. The date a contract ends, the price and the notice address often come from the latest amendment. Reading only the original is a frequent cause of wrong renewal dates.
