Effective Date
The date the contract's rights and obligations actually start.
What it means
The effective date is the date a contract's rights and obligations begin — which is not always the day it was signed. Contracts can state an effective date earlier than signing (covering work already underway), on signing, or at a future date or triggering event. When the parties sign on different days, the contract often defines the effective date as the date of the last signature.
Why it matters before you sign
Deadlines, terms, and renewal windows are usually measured from the effective date — make sure you know what that date actually is, especially when it is not the day you signed.
In a contract, it looks like this
Although the parties signed in March, the agreement stated an effective date of January 1 to cover services already being performed.
