can at any time a person's bank account be brought into court as evidence ?
there willl always be a test of relevance for any evidence to be admissible. if the bank records are relevant, then they can be admitted as evidence. such records can be subpoened, with the bank served with a subpoena and required to attend court with the documents, it what you are talking about are records not of yourself but the opposing party.
