How to Change Borrower's Insurance: A Practical Guide
How to change borrower's insurance in France with the Loi Lemoine. Eligibility, documents, model letter, bank rules, and tips to switch and save.
Since 1 September 2022, French borrowers can change borrower's insurance at any time under the Loi Lemoine. If your mortgage insurance still came from the bank, you're probably not stuck with it, and you can now replace it without waiting for the first year or the old anniversary window.
That's the useful starting point when a borrower realizes the premium has aged badly, the coverage feels too rigid, or the bank contract looks expensive compared with what's on the market. In practice, the question isn't whether you can change. It's whether your file will pass the bank's equivalence check the first time.
Why French Borrowers Switch Mid-Term
A common file lands on my desk like this. The mortgage is already running, the borrower has paid for years, and the insurance line on the statement has slowly become harder to justify. Nothing dramatic has happened, but the policy no longer feels aligned with the borrower's real life, especially when the original bank contract was chosen quickly at signing.
People usually switch for three practical reasons. They want a better price, they want clearer coverage, or their situation has changed enough that the old policy no longer fits. That can mean a new job, a change in smoking status, a shift in family responsibilities, or the feeling that the bank's group insurance was never the best deal in the first place.
The point is not only cost, although cost matters. It's also flexibility. A borrower who understands how to change borrower insurance in France can compare contracts more calmly, instead of accepting whatever was attached to the loan offer on day one. The reform from the Loi Lemoine matters because it moved the market away from a rigid switching regime and made the process continuously available for borrowers who want to reduce cost or improve coverage, as explained by the French public service page on mortgage insurance switching economy ministry guidance.
Practical rule: don't start from the premium alone. Start from the coverage you'd actually want if the bank asked you to defend the file criterion by criterion.
That's why serious borrowers treat this as a refinancing-style review, not a quick cancellation. When the file is well prepared, the switch can be straightforward. When it's rushed, the bank often finds a reason to slow it down.
Who Can Change and When Hamon, Bourquin, Loi Lemoine
Many borrowers ask me if they missed their window. The short answer is no, provided you clearly distinguish the historical timeline of the rules applicable today. Hamon opened the possibility to change during the first year of the loan. Bourquin then established an annual window. With the Loi Lemoine, the logic has changed, because since 1 September 2022, it is possible to change at any time for ongoing contracts, and for new mortgage loans taken out from 1 June 2022, as recalled by the official government information page on borrower insurance termination economy ministry guidance.
For most standard residential files, this means there is no longer an anniversary date to wait for. If the insurance is linked to a classic mortgage loan, the file can be launched as soon as the borrower has a serious replacement offer. The old timeline mainly serves as a reference point, because many individuals still think in terms of the old termination window and postpone a request they could already send.
The Concrete Eligibility Check
The real filter is not the timeline, it's the consistency of the replacement contract with the bank. The insurance must always meet the requirement of equivalence of guarantees, and that's where the files are decided. In practice, each co-borrower must be treated consistently with the structure of the loan, as the bank looks at the insured risk on the overall contract. If the loan has already been partially repaid, this does not eliminate the right to change, it only means that the request must be aligned with the remaining balance and with the loan file as it exists with the lender.
There are special cases. Some professional loans follow different rules, and a loan still at the offer signing stage must be treated as a subscription, not as a substitution. A contract without a real annual rate review can also complicate the comparison, because the displayed price does not always indicate how the insurance behaves over time.
What matters today is not having missed an old deadline. It is having a complete file, compatible with the bank's criteria, and a replacement offer already ready to be sent. This is where the request has the best chance of succeeding.
The Equivalence of Guarantees Test the Bank Will Run
The bank doesn't judge the request by price, it judges it by the equivalence of guarantees rule. In France, that test is based on the Fiche Standardisée d'Information (FSI) the bank gave with the original loan offer, and that sheet typically lists 11 or 15 guarantee criteria depending on the loan profile Santiane guide.
The practical point is simple. The new contract must be at least as strong as the current one on the criteria the bank flagged in that FSI. If the replacement is cheaper but weaker on one required line, the bank can refuse it. If the coverage is equal or stronger on every required line, the bank has far less room to object.
How the bank actually reads the file
The bank compares the old and new contracts line by line. It looks closely at the coverage wording, not just the broad guarantee name. Death, total and irreversible loss of autonomy, incapacity, and sometimes unemployment tend to be the lines where mismatches appear, because contracts often look similar at first glance but differ in exclusions, activation conditions, or scope.
The FSI is your map. If you don't have it, ask the bank for it before doing anything else.
That document matters because it gives you the exact comparison grid the bank will use. If you don't match the bank's list, you're comparing the wrong thing. If you do match it, you can often spot the weak point before the bank does.
A good self-check is to read the FSI from top to bottom and ask one question on each criterion, “Does the new policy clearly meet or exceed this line?” If the answer is fuzzy, the file isn't ready yet. This is also where many borrowers lose time, because they buy the cheapest quote first and only later discover that one criterion is just a little too narrow.
Comparing Offers and Building Your Substitution File
A proper comparison starts with three to five quotes, not one. That is enough to see whether the market really gives you a better fit, without forcing you to sort through near-identical proposals. A broker or comparison platform can help surface options, but the borrower still has to read the contract terms carefully, because the lowest monthly premium is often not the safest choice.
The first things to compare are the exclusions, the waiting periods, the way the insurer handles occupational declarations, and whether the premium changes with age or follows the same logic for the whole loan. A contract that looks attractive on a quote page can become far less interesting once you read the clauses on psychological claims, non-working-time exclusions, or specialist occupations. For example, some policies exclude claims tied to pre-existing conditions after a short waiting period, which can leave a real gap if the borrower assumes that condition is covered.
What should go into the file
The substitution file is stronger when it is built like a bank dossier, not like a shopping basket. Include the signed substitution request, the new insurance certificate or adhesion attestation, the general conditions, and the specific guarantees table. If the insurer provides an equivalence grid, add it too, because it helps the bank check the match faster and cuts down on back-and-forth.
A clean file also lets the bank's reviewer see the comparison quickly. When one piece is missing, the bank often asks for more, and the timeline drifts for no good reason. That is why the comparison stage matters so much. It prepares the equivalence test before the request leaves your hands.
For borrowers who are still house-hunting, the same disciplined comparison habit applies to the wider purchase file, as explained in this practical guide on buying an apartment in France and our model promise to sell. The insurance file works the same way, start with the conditions, then make the numbers fit.
If you want to find better insurance rates, the price still has to be read alongside the contract limits, not instead of them.
Good file, good outcome: if the bank can verify the equivalence without guessing, the request usually moves faster.
A useful rule is to reject any contract that hides its limits behind a low headline price. Look for the exact clause that weakens the cover, a narrow definition of incapacity, a longer waiting period, an exclusion for back problems, or a condition that only applies after a medical history declaration. You are not buying the cheapest monthly line, you are buying a policy the bank can accept.
Sending the Request and the Model Substitution Letter
The request should be traceable from day one. In practice, that means registered mail with acknowledgment of receipt, email, or the bank's online portal if it leaves a clear audit trail. The bank's legal response period is 10 working days once the file is complete, and sources note that the new contract's effective date is often set around one month after the request so the processing window isn't too tight France Epargne academy.
A model letter you can adapt
Monsieur, Madame,
I am writing to request the substitution of my current borrower's insurance for loan number [loan number], linked to insurance contract number [contract number], in accordance with Article L. 113-15-2 and Article L. 313-30 of the Insurance Code.
Please note that I wish this substitution to take effect on [requested effective date]. You will find enclosed the signed request, the new insurer's adhesion certificate, the policy conditions, and the documents needed to verify equivalence of guarantees against the FSI.
I ask you to confirm your acceptance in writing within the legal timeframe and to issue the free amendment if the request is accepted. If you consider any criterion not to be equivalent, please provide the detailed reason for refusal.
Yours faithfully,
[Name]
[Signature]
Delivery channel comparison
| Channel | Proof of sending | Traceable | Typical bank response speed |
|---|---|---|---|
| Registered letter with acknowledgment of receipt | Strong | Yes | Often slower to open, but strongest evidence |
| Medium to strong if properly archived | Yes | Usually faster to route internally | |
| Online customer portal | Strong if message and receipt are saved | Yes | Often the fastest to log |
A practical way to avoid a gap is to set the effective date about one month ahead, then send the file immediately. That gives the bank room to ask for a missing page without forcing you into a coverage gap.

Common Reasons Banks Refuse and How to Preempt Them
Most refusals aren't mysterious. They usually come down to one of four issues, an equivalence gap on a single criterion, a missing document, stricter exclusions in the new contract, or a request that was sent with timing the bank can't process cleanly. In real files, the bank often focuses on one weak line rather than the whole policy, because that single line is enough to break equivalence.
The cleanest response is to ask for the refusal in writing, then compare the bank's reason line by line against the FSI and the new contract. If the refusal is about a criterion the new insurer covers in an equivalent way, the issue is often wording or missing evidence, not substance. If the bank is right, the second submission needs to be tighter, not louder.
What to do when the first answer is no
Ask for the detailed reason. Re-check the FSI mapping. Then send a revised file with the exact missing proof, not a vague complaint. If the refusal is legally unfounded, the borrower can escalate inside the bank, then, if needed, turn to the relevant external channel such as the ACPR or the bank's mediator.
Practical rule: a refusal is often a document problem dressed up as a policy problem.
The best pre-emption is to eliminate the obvious mismatch before the file goes out. That means reading the exclusions carefully, checking the guarantee wording against the FSI, and making sure the insurer has not built in a narrower scope on a criterion the bank explicitly demanded. I've seen many second attempts succeed because the borrower changed the wording and attached the right document, not because the insurer changed.
The Loi Lemoine framework is the borrower's strongest ally here, because the bank has to justify a refusal. If the reason is thin, challenge it. If the reason is real, fix the file and resubmit quickly.
FAQ and a 7-Step Action Checklist to Switch Today
A few questions come up again and again once borrowers understand the mechanics. If you've had a health event since signing the loan, the key issue is not the event itself, it's whether the new contract and any declaration you make to the insurer still satisfy the bank's equivalence test. If there's a co-borrower, both sides of the coverage profile need to be consistent with the loan structure.
Can the bank refuse because the new insurer is foreign? Not just because it's foreign. What matters is whether the policy meets the bank's required guarantees and can be documented properly. The same logic applies if you're comparing options while also reviewing broader refinance timing, which is why the guide for Essex homeowners remortgaging can be a useful parallel read on timing discipline, even though the legal framework is different.
For readers working in regulated sectors, the same comparison mindset shows up in other insurance workflows too, including the practical guidance on insurance solutions. The process is different, but the discipline is the same, compare the cover first, then the price.
7-step checklist
- Pull the FSI from the original loan file.
- List the required guarantees and note the exact wording.
- Request three quotes and compare exclusions, not just price.
- Check equivalence line by line before you sign anything.
- Build the substitution file with the certificate, conditions, and signed request.
- Send the request through a traceable channel.
- Archive the bank's amendment once accepted, then store every proof.
If you want a smoother switch, start today by pulling the FSI and getting one serious quote that's designed to pass the bank's test, not just to look cheap on paper. Then send the file with a clear effective date and keep your proof of delivery.
