In a legal dispute, one party may file a motion to compel if the opposite party is withholding supportive documentation, instead of submitting it for inspection, states Cornell University Law School. Another example is a motion to compel a testifying party to complete a deposition.
Another type of motion known as an interrogatory may compel one party to answer questions submitted by the other party, Cornell University Law School explains. One party can file a motion to compel after making reasonable attempts to obtain the requested information from the opposing party.
During the pretrial process known as discovery, all parties are entitled to access to specific types of evidence or testimony, according to the American Bar Association. This process prevents one party from withholding evidence in an attempt to hinder the opposite party's preparation for the trial.
