Whenever possible, strive to include signed contracts. There is no requirement that contracts are fully-executed, however, it is not advisable to rely solely on unsigned contracts. At the very least, some of the contracts should be signed by one party. In lieu of contracts, it is perfectly acceptable to include letters of intent, deal memos or other written confirmation of dates listed on the itinerary. Remember that for multiple venue petitions, agent appointment letters should be completed by other employers and by the beneficiary artist/entertainment group.
