How do you handle your split sheets?

[kikomori]

Hello Producers and Composers! I currently have a couple of orders in which I’ll have to keep 50% of the songwriting royalties. Usually I’d just sign a splitsheet along with the musicians, but in this case, since we’re doing it online, I can’t do this because I’m scared that my signature might get stolen (same thing for my client). Is there an easier way to do this?

Cheers!
