Received Letter In The Mail From A Law Firm With My Father And I's Names On It.

I recieved a letter in the mail today from a law firm (that I researched and is real). It claims that the responsible party(ies) are my father and I, and that we owe over $10,000. I'm quite perplexed because:
1. I haven't spoken to my father in several years

1. This law firm is a firm for property and/or personal injury damages

2. I have not been involved in any accidents or have caused any damage

I will say, part of the reason I don't speak to my father is because he has always been trying to cheat the system, get away with things, etc. He's just kind of a shady character and never gave me a super stable childhood. I wouldn't be surprised if this is something to do with that. Although, I don't think he would be trying to get me involved in any way. He isn't usually malicious like that.

How should I proceed? Should I contact the law firm? My father? I don't see how I could have became a responsible party in this matter and I don't wanna get stuck in some stupid mess that isn't my fault.

TIA!
