Legal Question in Family Law in Maryland

"Discovery" involves formal information gathering.

This is usually done by interrogatories (written questions), Document Requests (requests to give certain paperwork/information), Subpoenas (court orders to show up and/or produce something) or Depositions (testimony under oath outside of the courtroom). The Maryland Rules of Civil Procedure describe what discovery is available and time frames for responding. A scheduling order may place further limits on the timing of discovery.

The specific types of information you might want to gather by any of these forms depends a lot on the particular circumstances of your case and is best determined in consultation with a lawyer.
