Question 1

Is the commencement date the same as the effective date?

Accepted Answer

Often, but not always. The effective date is when the contract becomes binding. The commencement date is when specific obligations (like paying rent or starting work) begin. A lease might be effective (binding) on March 1 when you sign it, but the commencement date (when rent starts) could be April 1.

Question 2

What happens if the commencement date isn't specified?

Accepted Answer

The contract likely takes effect on the date both parties sign it. But this can create problems if you assumed you had prep time before obligations kicked in. Always specify the commencement date explicitly — especially in service agreements and leases where timing affects money.

Question 3

Can a commencement date be retroactive?

Accepted Answer

Yes. Contracts sometimes set a commencement date in the past to cover work or arrangements that were already underway informally. This is common when parties started working together before the paperwork was finalized. Make sure both parties agree on the retroactive date and understand the implications.

Question 4

What happens if work starts before the commencement date?

Accepted Answer

Work done before the commencement date may not be covered by the contract's protections — insurance, indemnification, IP assignment, and liability clauses might not apply. If you start early, consider amending the commencement date or adding a clause that covers the interim period.

Question 5

How does the commencement date affect contract deadlines?

Accepted Answer

Most deadlines and milestones in a contract are measured from the commencement date, not the signing date. If a contract says 'deliverables due within 90 days,' that's 90 days from the commencement date. Misunderstanding this can mean missing deadlines you thought you had more time for.
