Can you serve legal separation papers to another who does have a permanent address to serve them to?

Yes, you can serve legal separation papers to someone without a permanent address, but you must follow specific legal procedures. Typically, you may be permitted to serve the papers through alternative methods, such as posting them at their last known address or through publication in a local newspaper, depending on the laws of your jurisdiction. It's crucial to check local rules or consult with a legal professional to ensure compliance with the required procedures.
