A legal remedy is a way to set things right when your rights aren’t respected.
How do legal remedies work in practice?
When your rights aren’t respected, sometimes the law is able to take action.
A court might make whoever didn’t respect your rights change their behaviour. That means they would have to respect your rights in the future.
Or the court might make whoever didn’t respect your rights give you something in return. For example, they might have to give you money.
These are just two kinds of legal remedy. Depending on what’s happened, there may be others.
