You don't need a specific amount upfront to sue, as costs vary greatly, but expect potential expenses like small claims filing fees ($30-$100+) or thousands for complex cases, plus attorney fees (hourly or contingency, meaning you pay a percentage if you win).

Causation, linking an action directly to harm, is notoriously difficult in medical malpractice, and proving a specific mental state at the time of a crime (like insanity) faces significant challenges with expert testimony and jury skepticism. 

What are 5 examples of evidence?

The specific elements to prove (like breach of contract or harm) depend on the case type, but the core standard is slightly more convincing evidence than the defendant's.
