Bank Disclosure in Marital Protection Proceedings Overriding Secrecy for Spousal Support Determination

In marital protection proceedings, the higher court upheld a lower court's order compelling a bank to disclose account records where the husband had signatory power, even if the accounts were not in his name, balancing the bank secrecy interest against the spouse's and child's need to determine the husband's actual financial means, especially when the husband claimed minimal income from public benefits while evidence suggested professional activity generating undisclosed income. The court reasoned that the ability to manage third-party accounts is a relevant indicator of potential professional income or hidden assets pertinent to support obligations, and in this case, the immediate existential need of the dependent spouse and child to secure maintenance outweighed the customer's interest in discretion, given the questionable credibility of the husband's financial disclosures.
