The bank's former head of lending, Tom Browne, secured the discovery orders at the Commercial Court as part of his defence to a case taken by the bank to recover €50m in unpaid loans.
Mr Browne will also be given access to information on Anglo's loans to businessman Sean Quinn and his family.
The bank had agreed to release some of the documents, subject to confidentiality obligations, but Mr Justice Peter Kelly said he was entitled to more information.
The court also ruled he was entitled to ask questions about Anglo's loans to directors and about the reasons for the movement of €7.3m in loans between Anglo and Irish Life and Permanent.
The judge said this information could be elicited through correspondence or 'interrogatories' and would not require an order for discovery.
Mr Browne alleges Anglo engaged in wrongful and unlawful conduct which undermined the bank's stability and failed to inform him of these activities.
He claims he would not have executed his share options and borrowed money to buy shares in 2007 if he had been made aware of the situation and would not have suffered losses when the share price collapsed.
He claims the banks engaged in deceit and fraudulent misrepresentation to induce him to enter into loan agreements, which he claims are now void and invalid and should be set aside. The bank denies the claims.
