Residuals will go to the representative you had when you booked the project, even if you no longer are represented by him/her.

In theatre, union rules require you to be paid each Thursday. The check is generally presented to you at the theatre during rehearsal or before your evening show. You are then responsible for paying your representative his/her commission in a very timely fashion. Sometimes theatre companies will deduct your rep's commission from your checks and send the commission directly to your representative (but only if you authorize this). Sometimes actors prefer to have their whole check mailed to their representative in order for the representative to take out his/her commission and send the balance back to the actor.
