When Reminders Aren't Enough: Small Claims, Demand Letters, and Legal Rights in Quebec

Most late invoices get paid once a contractor sends a few well-timed reminders. A nudge at 7 days, a direct follow-up at 21, a final notice at 45 — and most clients pay.

But some don't. And when that happens, you need to know what your actual options are in Quebec. There is a full escalation ladder between "reminder ignored" and "write off the debt." Most contractors know maybe two steps on it.

This post maps out the full ladder and what each step involves.

The escalation ladder

The stages in order: friendly reminder, direct follow-up, formal demand letter, hypothèque légale de construction (if the work was on a property), small claims court, collection agency. Most invoices resolve in the first two stages. The rest of this post covers what happens after that.

Before reaching the demand letter stage, make sure you've sent a complete reminder sequence. A formal demand letter carries more weight when the client has already received multiple documented attempts.

The formal demand letter (mise en demeure)

A mise en demeure is a formal written notice that creates a legal record. It is the last step before filing anywhere. Sending one often moves a stalled client because it signals you are serious and have started a paper trail.

Under Quebec law, a valid mise en demeure must include five things:

1. Clear identification of the creditor and the debtor
2. The amount owed with the invoice reference number
3. An explicit demand for payment, not a request
4. A reasonable deadline to comply — typically 10 business days
5. A clear statement of your intended next steps if they don't pay (small claims, hypothèque légale, etc.)

A mise en demeure can be sent by registered mail or by email with a read receipt. You don't need a lawyer to write one, but the tone and precision matter. Keep a copy. This document may be referenced in any legal proceeding.

Quebec small claims: the $15,000 limit

Quebec's small claims court handles disputes up to $15,000. The limit was raised from $7,000 in 2021. Most contractor invoices fall within it.

Filing costs between $100 and $200 depending on the claim amount. You don't need a lawyer — lawyers are actually prohibited from representing parties in small claims. You show up, present your invoices and documentation (including your reminder send history), and a judge decides.

Count on 3 to 9 months between filing and judgment. It is not fast. But for amounts over $2,000 to $3,000 that a client is clearly refusing to pay, it is often worth it.

For official filing information, see the Quebec Ministry of Justice website.

The hypothèque légale de construction

If you did construction, renovation, or installation work on a property and haven't been paid, you have a right under the Civil Code of Québec (arts. 2724–2732) to register a legal hypothec on that property. This is the hypothèque légale de construction. It is separate from a regular mortgage and does not require the property owner's consent.

The critical detail: you have 30 days from the date work was completed to register the hypothec at the registre foncier. Miss that window and the right is gone.

Who can use it: general contractors, subcontractors, material suppliers, architects, engineers — anyone who contributed labour or materials to a construction project on that property.

What it does in practice: registering a hypothec makes it very difficult for the property owner to sell or refinance until the debt is settled. It is a serious tool. You will likely need a notary to handle the registration. The cost is typically $300 to $600.

The full legislative text is at article 2724 of the Civil Code of Québec.

Collection agencies

Collection agencies take a percentage of what they recover — typically 25% to 40% of the outstanding balance. You pay nothing if they collect nothing.

When it makes sense: for smaller invoices ($500 to $2,000) where small claims court isn't worth your time, or for clients who have moved or are hard to locate. Agencies have skip-tracing tools most contractors don't.

The trade-off: you give up a third of the money, and there's no guarantee they collect anything. But if the alternative is writing off the balance entirely, it may be worth it.

Reminders before legal steps

Before considering any of the above, exhaust your reminder sequence. Most invoices are paid by the end of it. And every message you send gets logged with a timestamp — if you end up in small claims court, that send history is documentation showing you attempted collection in good faith before escalating.

Relanco runs your reminder sequence automatically. When the sequence ends with no payment, your paper trail is already there.

Frequently asked questions

Does sending a mise en demeure guarantee I will get paid?

No, but it demonstrates you made a formal demand and creates a clear record before any court filing. Many clients who ignored earlier reminders will pay once a registered letter or formal email with the required five elements arrives. It also documents good-faith collection effort if the case goes further.

Do I need a lawyer to file in Quebec small claims court?

No. Lawyers are prohibited from representing parties in Quebec small claims. You file yourself, present your invoices and documentation, and a judge decides. The process is designed for exactly this kind of dispute. Filing costs $100 to $200 depending on the amount claimed.

How long do I have to register a hypothèque légale de construction?

Thirty days from the date the work was completed. After that window closes, the right no longer exists. If you are approaching that deadline, act before going through any other steps. You will need a notary to handle the registration at the registre foncier.

Automated reminders collect most overdue invoices. When they don't, you now have a clear picture of what comes next. Relanco handles the reminders. The legal options, you pursue with a clean paper trail already in hand.
