Here’s the short answer – anyone can sue anyone… the real issue is whether a law suit will be successful. Can the other party’s insurance sue your sister to recoup what they paid in uninsured/underinsured? You bet. Now, whether there’s a defense at law to help protect her in a lawsuit or potential judgment, I simply can’t say on your description alone. From your description, a lawsuit for the $25,000 has been filed and served against your sister. I’m assuming this happened recently and no Clerk’s Default or Default Judgment has been entered. Once served with a lawsuit, she has 20 days to file a response. She needs to consult with an attorney ASAP. If she has any defenses, she needs to raise them properly and do so before a default is entered against her.
