- Who to sue,
- Where they are,
- What you need to do before you sue them,
- Where you should sue them, and
- If you should sue them.
These are hard questions to answer, even in an easy case like a slip-and-fall in a store. For example, if you slip on the floor in a supermarket, you have to figure out if the store is part of a chain or just one store, if falling was partly or totally your fault, etc.
