What quantum meruit means
Quantum meruit is payment for work done when the contract cannot tell you what to pay.
It arises where somebody requested work, the work was done, and there is no enforceable agreement on price. Rather than let the person who received the benefit keep it for nothing, the law allows a claim for what the work was reasonably worth.
It is restitutionary in character. The measure is not what the claimant hoped to earn or what they would have made had the contract run its course. It is the reasonable value of what was actually provided.
Several situations produce it. No price was ever agreed. The contract was void or unenforceable for a technical reason. Work was done outside the scope of an existing contract at the other party's request. Or the contract was terminated part way through and the work already done was of value.
How it is used
For Nigerian freelancers, consultants and contractors, this is the claim that exists when the paperwork does not.
A designer produces a brand identity on a verbal brief and the client disappears. A contractor completes two of three phases before the project is cancelled. A consultant is asked to add work outside the scope and the variation is never documented. A supplier delivers on a purchase order that was never signed.
In each case, if there is no enforceable term about price, the claim is for reasonable value.
Proving it requires evidence of three things. That the work was requested or accepted, which is where emails, WhatsApp messages and briefs matter. That the work was done, which is where deliverables, drafts and progress records matter. And what it was reasonably worth, which is where market rates, your own usual rates and any figures discussed matter.
A demand letter setting out those three things, with the evidence attached, resolves a good number of these before anybody goes near a court.
Key features
- A claim for the reasonable value of work done
- Arises where no price was agreed or the contract falls away
- Restitutionary rather than compensatory, so it does not include lost profit
- Requires proof of request or acceptance, performance, and value
- Available for work outside the scope of an existing contract
- Commonly pleaded as an alternative to breach of contract
How this works in Nigeria
Nigerian courts recognise the claim, and it does real work in a market where a great deal of commercial activity is transacted on WhatsApp and trust.
The practical difficulty is proof of value. Without a rate card, a quote, or evidence of what similar work costs, a claimant is asking the court to pick a figure. Freelancers who send a written quote before starting, even when the client never signs it, put themselves in a much stronger position, because the quote becomes evidence of the value discussed.
The second difficulty is establishing that the work was requested. A person who did work speculatively, hoping to be paid, has a weaker claim than one who was asked. Confirmation by email or message saying please go ahead is the difference.
It is also usually pleaded in the alternative. The primary claim is breach of contract, on the basis that a contract existed and was breached, with quantum meruit as the fallback if the court finds there was no enforceable contract. That structure is standard and worth knowing about.
Quantum meruit vs breach of contract damages
Two ways to be paid for work, measured very differently.
Damages for breach of contract put you in the position you would have been in had the contract been performed. That includes the profit you would have made on the remaining work, which is why a contractor terminated at the halfway point can claim more than the value of what they built.
Quantum meruit pays the reasonable value of what you actually did. No lost profit, no expectation, just what the work was worth.
So the first is better where an enforceable contract exists and you can prove it. The second is the fallback where you cannot, and it is why a written contract is worth more than most freelancers assume.
A claimant usually pleads both: the contract claim first, quantum meruit in the alternative, so a finding that no contract existed does not end the case.
Limits and risks
It does not compensate for lost opportunity or profit. A claimant who turned other work away and lost a large project recovers only the value of what they did.
It also depends on the work being requested or accepted. Unsolicited work is generally not recoverable, however useful it turned out to be.
Where an enforceable contract does cover the work and fixes a price, quantum meruit is not available. The contract governs, even where the price now looks unfair.
And valuation is uncertain. Without evidence of rates the court is estimating, and estimates tend to be conservative.
Worth knowing
Send a written quote or scope before starting work, even for a client you trust, and get any expansion of scope confirmed in a message. Nigerian freelancers lose these claims not because the work was not done, but because nobody can establish what it was worth or that it was asked for.
Questions people ask
What does quantum meruit mean?
As much as they have earned. It is a claim for the reasonable value of work done, available where no price was agreed or where the contract fell away before payment.
Can I claim payment without a signed contract?
Often yes. Where work was requested and done, a quantum meruit claim for its reasonable value can be brought even though no enforceable agreement on price existed.
How is the reasonable value calculated?
By reference to market rates, your usual rates, any figures discussed, and the nature and extent of what was delivered. Without such evidence the court is estimating, and estimates tend to be conservative.
What is the difference between quantum meruit and damages for breach?
Damages put you where you would have been had the contract been performed, including lost profit. Quantum meruit pays only the reasonable value of work actually done, with no expectation element.
Can I claim for work I did without being asked?
Generally no. The claim depends on the work having been requested or accepted. Speculative work done in the hope of payment is usually not recoverable, however valuable it turned out to be.
What evidence do I need?
Proof the work was requested, such as emails or messages. Proof it was done, such as deliverables and drafts. And proof of value, such as a quote you sent, your rate card, or evidence of market rates.
