In Pennsylvania, the penalty for late filing of divorce papers can vary depending on the specific circumstances and the discretion of the court. Generally, if a party fails to file divorce papers within the required time frame, it may result in delays in the divorce process and can potentially affect the final outcome of the case. The court may also impose fines or other penalties if there is a significant and unjustified delay in filing. It is advisable to consult with an attorney to better understand the specific consequences for late filing in your situation.
