APHA unfortunately won't help you much in this situation unless you can get the "owners" who still have the papers to turn them over to you. If you know their name, it is still worth giving APHA a call and sending photos in so they can match him and put a flag on those papers. At least APHA will know they have a dispute.
You can however register him with the Pinto Horse Association for less than $100. They have many great showing opportunities too.
If he was actually rescued by a recognized group or seized by governmental authority, APHA may transfer the papers to you if you can show them the rescue/seizure documents.
