An at issue memorandum is a legal document usually filed in a civil case. It states that all the parties in a case have been served and that the parties are at issue (or in disagreement) over one or more points that need to be resolved at trial.
All of the issues to be tried are included in the at issue memorandum, as well as the estimated time required for trial. It is usually filed after the defendant responds and it indicates that the case is ready to go to trial.
