Getting ordained?

I will be officiating a friend’s wedding soon, and am looking to get ordained. I am not religiously affiliated in any way.

(To my understanding) Indiana doesn’t require state certification, but I don’t want my friends to run into any trouble filing their paperwork. If I go through something like Universal Life Church, is that legit enough? It just seems….too easy…

Please advise!

Edit: wow, okay! Guess it is just that easy lol. Thank you guys for your input, looks like I’ll be ULC certified.
