Plain-English Summary (for reference only — not a substitute for the rule text above)
This summary is not the rule. The rule text controls.
If you are a defendant in a lawsuit, you can bring other people into the case who you think share responsibility for what the plaintiff is claiming. This means you do not have to face the lawsuit alone if you believe someone else is partly or fully at fault.
You can add someone new to the case if you think they are the only one actually responsible, if they owe you money or coverage because of the lawsuit, or if they share the blame with you. You can also make a claim directly against another defendant who is already part of the case.
This rule applies to both original defendants and anyone who was already added to the case as an additional defendant. Either type can use this rule to bring in more parties or point to others who should share in any potential payment to the plaintiff.
