This is the classic scene of condominium life: a stain on the ceiling, a knock on the door upstairs, and the question that immediately points in three directions – my insurer, the neighbour's or the building's? Leak cases are difficult not because the rule is complicated, but because they look different from the point of view of each of the three parties. This article – the expanded successor of the quick-guide piece – shows all three at once.
- Three possible lines: the injured party's own home insurance (settlement under your own policy), the liability cover of whoever caused the damage (where there is negligence), and the building's policy (where the source is common property).
- The question of “which one pays” is decided by the source of the damage – which is why the first substantive step is always to find that source.
- For the injured party their own insurer is typically the fastest route; the insurers can settle liability between themselves afterwards.
The three lines – who goes where?
1. The injured party's own home insurance. For the owner of the flat that has been soaked this is typically the fastest route: their own insurer pays for the damage to the flat on its own terms, and then – if someone else is liable for the damage – can pursue a claim against them afterwards. 2. The liability line of whoever caused the damage. If the damage originates in the privately owned pipework of the upstairs flat, and negligence attributable to the neighbour can be established (e.g. a known defect left unaddressed, or a lack of maintenance), the liability line – typically the liability section of their home insurance – can apply. Absent attributable fault (e.g. a hidden pipe defect), the neighbour is typically not liable; in that case, the injured party's own insurance may pay. 3. The building's policy. If the source is common property – a riser, the roof, a shared section of pipe – the building's insurance responds, and the claim runs through the property manager. On ownership boundaries: where the line runs.
What should the injured party do?
In order: mitigation and photos; a message to the flat above and to the manager (so the source can be shut off as soon as possible); a report on their own home insurer's claims line – even if “the neighbour is to blame anyway”: your own insurer is the fastest route, and winning the argument about liability is not the injured party's job. If you have no home insurance of your own, what remains is claiming directly against the party who caused the damage or against the building – a slower, bumpier road, which is in itself a good argument for having your own policy.
What should the “party at fault” – and the manager – do?
Two pieces of advice for the upstairs resident: do not admit liability on the spot (that is for claims handling to settle – a well-meaning “of course, I'll pay for it” can backfire later), but cooperate fully: allow the exploratory work, report the damage to your own insurer on the liability line, document everything. The manager's job is to organise the search for the source – shared or private section? –, to report on the building's policy where common property is affected, and to keep the parties informed. The practical process: water damage in practice.
And if it turns into a dispute?
The typical way leak cases stall: everyone points at the other's insurer while the repairs stand still. The solution is usually in the documents – the photos of the opened-up surfaces and the expert opinion settle the question of the source. If a case affecting the building's policy stalls or becomes disputed, I step in as broker and help the building: this is how it works. And the lesson is nearly always the same: the condition of the risers and prevention cost less than repainting ceilings.
