The correct answers are: Subsequent illegality of the venture; Expiration of a fixed term partnership; Notice by a partner in a partnership of indefinite duration.

Criminal or civil proceedings against a partner will not affect the partnership unless they result in bankruptcy or unless there is a written agreement which specifies otherwise. A partnership for a fixed term will terminate as soon as that term expires, or, if it was for an indefinite period, when any partner serves notice to bring it to an end. If the purpose of the partnership becomes illegal, that will also serve to terminate it automatically.
