exactly. and if you get paid, you won't be going to court anyway! But no, getting the contract notarized doesn't guarantee anything, so don't bother. You make two originals, you and the band's representative (whoever's writing the checks) sign both, you keep one and they keep the other. The tricky part, and it applies to what Camilo said, is how to keep the music in the studio. In the old days it was easy because cassettes made of mixes weren't the masters, so the client always had to settle up to get the master mix. Now, with everyone wanting CDs, you're basically letting the masters out everytime the band goes home "to check the mix". This also gets back to the schedule thing. It might be possible to not let the final mix of the final song out until you get your final payment. I dunno, if you're really worried, maybe you can give them the roughs in MP3 format or something. I have to say, I've been on the film side and out of the music side for a long time now, so as far as what format to give out I'm sure there are other options, but business is business and so you do have to be careful about what you let out. Not paranoid, because that's insulting to the client, but careful. If you're matter-of-fact and upfront about the business side, it avoids a lot of confusion and problems down the road.
