You need to have a lawyer involved from the beginning. It will ease a lot of pain. You need a good contract that will cover all bases. In terms of bugs, make sure that the project is developed with tests. Most outsourcing places don't test anything. At all. Include it and make sure that whoever ends up managing this has a build server like jenkins where the tests can run on every commit. The PM should be able to read code and see if the tests are actually meant to do anything. I've seen projects were the tests were just code asserting types.
