Family law issue at memmardium?
I think what you are asking is what is an "at issue memorandum"?
An at issue memorandum is a document (usually filed with the court) that states that adjectives parties to a case have be served, that the parties disagree (or are "at issue") over one or more points to be resolved at trial, and how much time the parties estimate will be required for trial.
A memo on the issue at foot
