In most escalator and elevator cases, responsibility is split among several parties, and sorting it out is a key part of the claim. The property owner is responsible for keeping its devices reasonably safe — but it almost always hires a separate maintenance company to inspect and service them under a contract, and that company can be responsible for a servicing failure.
If the device or a component was defectively designed or manufactured, the manufacturer can be responsible too, under product-liability principles. Which parties are liable usually depends on who controlled what failed: a servicing lapse points to the maintenance company and owner, while a design or component defect points to the maker.
The maintenance contract, the inspection and service records, and an expert examination of the device are how these questions are answered. Identifying every correct party — and the right insurance — is essential, because missing one can undermine an otherwise strong claim. It is exactly the kind of untangling we handle for you.
