Define: Deemed Approval

What does deemed approved mean?

Deemed approved means the law or a contract treats something as approved even though no one actually said yes. When a person or authority is required to respond to a request, document, or action within a set window and doesn't, a deeming provision converts that silence into an approval with full legal effect. The approval is a legal fiction: it's assumed, not expressed, but it binds the parties the same way an explicit consent would.

The point of the mechanism is legal certainty. Without it, a single unresponsive reviewer could stall a contract, a construction milestone, or a supply order indefinitely. By fixing a time limit and stating that inaction counts as approval, the applicable clause or statute keeps the process moving and shifts the risk of delay onto the party who has to act.

How deemed approval works in a contract

Deemed-approval language almost always defines four things: who must respond, what they're responding to, the time period they have, and the consequence of missing it. A typical term reads that if the reviewing party does not provide written notice of approval or rejection within, say, ten business days of receiving a properly submitted request, the request is deemed approved.

• The trigger. A valid submission in the correct form starts the clock. If the request is incomplete, the deadline often doesn't begin to run.
• The period. A defined number of days (business or calendar) during which the reviewer must act.
• The default. Failure to respond within the period. Silence, not a positive act, is what matters.
• The effect. The document, change, or action is treated as approved and the parties proceed as if consent had been given in writing.

For the deemed approval to constitute a valid consent, the request usually has to be submitted in accordance with the contract's stated notice requirements. Establishing a clear time limit and a defined form of notice given is what gives the clause its legal certainty.

Why businesses use deemed-approval clauses

For a commercial or operations team running project-based deals, deemed approval is a practical control on delay. It's common in agreements where one side depends on the other's timely sign-off: landlord consents under a lease, change orders in construction, milestone acceptance in a services contract, or approval of a purchase order under a supply agreement. The clause caps how long an approval can sit unanswered and removes ambiguity about what happens next.

The trade-off is that it can also expose a party to an approval they didn't intend to give. That's why well-drafted clauses set limits: clear conditions on what counts as a valid request, an unambiguous form of notice, and sometimes carve-outs for high-value or high-risk items that always need express approval.

Is deemed approval legally binding?

Yes, where it's validly created. Deemed approval isn't an automatic right; it only exists because a contract, statute, or regulation expressly provides for it. In the contractual context, its enforceability turns on the wording the parties agreed. In the statutory context (for example, certain planning or permit regimes), the governing legislation sets out the deadline and whether non-response results in approval. Because the effect can be significant, courts read deeming provisions closely, so precise drafting of the trigger, period, and applicable conditions matters for compliance with the governing rules.

If you're setting these clauses across many contracts, it helps to standardize the response period, the notice form, and the exceptions in a playbook so every deal treats deemed approval the same way. You can review related terms such as in-principle approval to see how approval concepts differ.

How it works in practice

Consider a SaaS company delivering a custom implementation under a master services agreement. The contract says the customer must review and approve each project milestone.

The relevant clause reads:

"If the Customer does not provide written notice of acceptance or rejection within ten (10) business days of receiving a completed Milestone Deliverable, the Milestone shall be deemed approved."

Here's how it plays out step by step:

1. Day 0. The vendor submits a completed milestone deliverable in the agreed form. The ten-business-day clock starts.
2. Days 1 to 10. The customer's team is busy and no one reviews it. No written acceptance or rejection is sent.
3. Day 11. The response window has closed with no reply, so the milestone is deemed approved.
4. Effect. The vendor can invoice for the milestone and move to the next phase, exactly as if the customer had signed off in writing.

Notice the two conditions that had to be met: the deliverable was complete and in the correct form, and the defined period lapsed without a response. If the submission had been incomplete, the clock may never have started, and the deemed-approval term would not have applied.

Deemed approved vs expressly approved

Both result in a binding approval, but how the approval arises is different. That difference matters when a dispute turns on whether consent was actually given.

A related but distinct idea is deemed accepted, which applies to acceptance of goods, services, or deliverables rather than approval of a request. It works the same way (silence past a deadline counts as acceptance), but the consequence is that the recipient loses the right to reject.

Example of a deemed approval clause

A short worked example makes the point. Suppose a services agreement says: "Any change request submitted in accordance with clause 7 shall be deemed approved if the Client does not respond within fifteen (15) business days of the notice given." Here the fifteen-day time limit establishes the certainty, the reference to clause 7 fixes what constitutes a valid request, and the silence past the deadline is what triggers approval.
