Do you have the desire to find out if there are any active arrest warrants out there in your name? One of the easiest ways to do that is to visit your local courthouse.
Your local police station will also be able to provide you with that information as well.
However, if you think about it, the last place you should be headed if you have an arrest warrant out in your name is to the place that will arrest you if you do...
The courthouse will ask for a proof of identification, as most jurisdictions have adopted privacy policies that require you to either be the person asking for the warrant or to have written permission from the person that is actually asking for the warrant.
The written permission has to be very specific in that it states you have the permission to not only perform the search, but it also has to state the reason you want to perform the search and that you have the permission to view the results, even though it might have incriminating information in it.
Good luck getting permission from the person you're looking up in those exact words.
Luckily, there are websites that are specifically designed to scrape, consolidate, and display all of the information not only in arrest warrants but in dozens of other types of public records such as divorce records, court records, property records, and much more.
Short of an official private investigator or criminal background check, which could cost thousands, these are your best bet in terms of safely checking the status of arrest warrants on anyone - yourself included.
