Section 362 of the Bankruptcy Code imposes the automatic stay the instant a bankruptcy petition is filed, without any separate court order. It reaches an expansive range of conduct: filing or continuing a lawsuit against the debtor, enforcing a judgment, perfecting or enforcing a lien, and most collection communications or actions against the debtor or estate property. The stay applies regardless of whether the creditor knew about the filing, though actual knowledge affects remedies for a violation.

The stay is not absolute. Section 362(b) lists statutory exceptions, including most criminal proceedings, certain family law actions such as child support enforcement, and some regulatory or police-power actions. A creditor who needs to proceed despite the stay — to foreclose on collateral, for example — must file a motion for relief from stay and show cause, such as lack of adequate protection or absence of equity in the property. A creditor who willfully violates the stay can face damages, including in some cases punitive damages and attorney's fees.

Because the automatic stay freezes an in-progress lawsuit the moment a defendant or plaintiff files bankruptcy, it functions as a hard procedural interrupt on any litigation timeline touching the debtor. Juricratic models the stay as a freeze dial that pauses the affected branch of a simulation rather than terminating it, letting a user see how the case tree resumes, and on what terms, once the stay is lifted or the bankruptcy concludes.

Litigation counsel monitoring an opposing party's financial distress checks for a bankruptcy filing before taking any further action in a pending case, since continuing to litigate after a stay arises — even inadvertently — can expose the litigant to stay-violation damages, and instead promptly evaluates whether a relief-from-stay motion is warranted.
