My partner locked me out of the business bank account, can I get the court to act quickly?

Possibly, yes, through what's called emergency relief, specifically a temporary restraining order or a preliminary injunction, court orders that can take effect on a timeline of days rather than the months or years a normal lawsuit takes to resolve. In more serious situations involving active fund dissipation, courts can also appoint a receiver, a court-supervised third party given authority to manage partnership assets during the pendency of the litigation, specifically to prevent further harm while the underlying dispute is resolved.

This type of emergency motion practice operates under an entirely different, much faster procedural track than a standard partnership lawsuit, and if partnership assets are genuinely being actively moved, spent, or otherwise dissipated right now, this is a situation requiring an attorney's immediate, hands-on involvement rather than a standard document-preparation service, given both the urgency and the specialized procedural knowledge genuine emergency relief requires.
