Who needs cover when a young person moves in?
Two people now share one roof, with separate belongings, habits and risks. Insurance must follow that change: the host's policy protects the home, the housemate's protects their liability and possessions, ideally without gaps or expensive overlaps between the two contracts.
The host's comprehensive home policy
A French multirisque habitation policy typically covers the building or the tenant's liability, contents, water damage, fire, theft and often personal liability. It remains the foundation of protection, even if the host now uses only part of the home day to day.
Owner, flat owner or tenant: three situations
A French homeowner is not legally required to insure a house, though going without would be reckless. In blocks of flats, the 2014 ALUR law requires every co-owner to hold liability cover. Tenants must prove each year that they are insured against tenant's risks.
When the host rents the home
An older tenant may take in a young person under the homesharing framework added to French housing law in 2018, provided the landlord is informed first. The tenant's insurance should then be updated, since the number of occupants is often part of the declared information.
Telling the insurer about the housemate
French insurance law requires policyholders to report new circumstances that change the risk, and taking in someone outside the family often qualifies. A short letter or message to the insurer before move-in day avoids a dispute when a claim is made later.
What to check in the policy wording
Three definitions matter: who counts as an insured person, which belongings are covered, and which exclusions apply to non-family occupants. Some policies cover anyone usually living in the household; others expressly exclude lodgers, subtenants or people paying for their accommodation.
Damage between insured persons
If the housemate counts as insured under the host's policy, a trap appears: most liability covers exclude damage caused by one insured person to another. A housemate who scratches the host's parquet would then be covered by nobody unless they hold a separate contract.
When the change in risk must be reported
Reporting should happen before arrival or as soon as the agreement is signed. The insurer may adjust the premium or suggest an option. An omission discovered after a fire can reduce the payout in proportion to the premium that should have been charged.
The housemate's cover: liability and personal belongings
Most homesharing charities ask the housemate for a liability certificate before move-in. It covers damage caused to others, including the host if they are not co-insured. Students may already be covered by their parents' policy, which should be confirmed in writing.
Who insures what? A quick reference table
The table sets out a common split, to be adapted to the contracts actually held. UK and US readers will recognise similar logic, although policy names and legal obligations differ from one country to another.
| Risk | Policy that responds first | Watch out for |
|---|---|---|
| Fire or water damage to the home | Host's comprehensive home policy | Housemate declared to the insurer |
| Housemate's laptop destroyed in a fire | Housemate's own contents cover, if any | Lodgers' belongings often excluded from the host's policy |
| Housemate breaks the host's furniture | Housemate's liability cover | Exclusion between co-insured persons |
| Housemate causes a leak into the flat below | Housemate's liability or host's policy | Occupant status must be clear |
| Theft from the housemate's room | Housemate's own policy | Break-in and locking conditions |
| A guest of the housemate is injured on the stairs | Host's or housemate's liability depending on fault | Set visiting rules in the agreement |
How much should be budgeted?
Stand-alone personal liability cover is usually inexpensive, and French student room policies are designed precisely for young people renting a single room. On the host side, any premium rise linked to the housemate can be discussed when setting the monthly contribution, without inflating it.
Steps before handing over the keys
- Read the definition of insured persons in the host's policy together.
- Notify the host's insurer in writing, giving the housemate's arrival date.
- If the host rents, inform the landlord and update the tenant's insurance.
- Ask the housemate for a liability certificate in their own name.
- Estimate the value of the housemate's belongings and choose suitable cover.
- Attach the certificates to the agreement and note renewal dates.
- Take dated photos of the room and shared areas on arrival.
Common insurance mistakes
Problems almost always surface at claim time, when it is too late to fix a contract. Several oversights come up again and again in homes shared between an older person and a young adult.
- Assuming the host's policy automatically covers the housemate's belongings.
- Saying nothing to the insurer for fear of a higher premium.
- Accepting a parent's liability certificate without checking it covers a child living elsewhere.
- Forgetting to renew the certificate at the start of the next academic year.
- Skipping the move-in inventory, which serves as evidence in any dispute.
Frequently asked questions
The answers below describe typical cases; only the general and specific terms of the contracts involved settle a particular situation, and the insurer remains the right contact to confirm whether a given guarantee applies.
The housemate breaks a valuable vase: who pays?
In principle the housemate's liability cover compensates the host, provided the housemate is not co-insured under the host's policy. For a high-value item, listing it specifically in the host's contract helps, since liability limits for such objects are often low.
A leak from the housemate's room floods a neighbour: what now?
Both occupants alert their insurers quickly and complete a joint water damage report with the neighbour. The insurers then share the cost according to where the leak started and each occupant's status in the home.
Can the charity require proof of insurance?
Yes, many charters make it an entry condition. They ask the housemate for a liability certificate and sometimes for confirmation that the host has informed their insurer. These documents usually go into the matching file kept by the charity.
Is the housemate covered if injured at the host's home?
If the accident results from the host's fault, the host's liability cover may apply. Otherwise the housemate relies on public health insurance and, if they hold one, a personal accident policy that pays for injuries where nobody else is responsible.
