Ask How do freelance platforms handle it when a third party claims ownership of work a freelancer delivered?

[Edward22]

This is a situation that does not happen every day, but when it does, it can get really complicated. Imagine delivering a project and then someone outside the contract shows up claiming that the work belongs to them. Maybe they say the freelancer used their content or copied their design. Platforms usually have a process for these kinds of disputes, but the steps are not always explained clearly to freelancers. If you have ever been caught in something like this, what did the platform actually do to resolve it?
