# Rule 301: Presumptions in Civil Cases
This rule explains how presumptions work in civil lawsuits. A presumption is a legal assumption the law makes unless someone proves otherwise. For example, the law might presume something is true until a party shows evidence that it isn't.
Here's how it works: if a presumption applies to your side of the case, you have to come forward with some evidence to challenge it. If you don't offer any evidence to fight back, the presumption stands and the other side wins that point automatically.
However, this rule doesn't change who has to ultimately convince the judge or jury of the whole case. The person who originally had to prove their case still has to prove it in the end. Fighting off a presumption just means you've done your part to keep the issue alive. It doesn't mean you've won that argument completely. The final decision about who is more believable, or who proved their case better, stays with whoever had that job from the start.
