A: I know people hate this answer from attorneys, but it depends on the wording of the contract and the specific facts of the situation.
Most contracts will have a clause governing assignment of the contract to a third party. That clause will determine if the terms of the original contract are assignable to the new company operating the venue. If the contract is not assignable, or if the original operator decided not to assign the contract to the new operator, then you will have a new agreement with the new operator.
Most contracts will also have a clause governing how the terms of the contract can be changed.
If you would like a review of your situation and your contract, you can request a proposal for a review session. I generally do those at a flat fee, based on the length of the contract. I'm sure other attorneys would offer similar rates.
