Effective date

Many contracts distinguish between three dates: the date of signature, the effective date, and the start of services. They often coincide, but not always.

Common patterns

• Signature date: the agreement is effective when the last party signs.
• Stated date: "effective as of January 1" even if signed later, sometimes called backdating.
• Conditional: effective once a condition is met, such as payment of a deposit or delivery of a bond.
• Amendments: each amendment has its own effective date, which determines which version of a term applies at a given time.

Why it matters

The initial term is normally counted from the effective date. A mistake of a few weeks moves the renewal date, the notice deadline and the date price changes apply.

Example

A services agreement signed on November 12 states: "This Agreement is effective as of December 1." The 12-month initial term ends on November 30 of the following year, not November 11. A non-renewal deadline of 60 days is then October 1.

Record the effective date from the contract text, not from the signature page. Compare with effective terms, which reflect the contract as amended.
