I agree with texasgal. It is not strange.
I ended up with an APHA registered horse a few years back (still have him) and the papers were a mess. Well, the whole situation the horse was in was a full blown nightmare. I contacted APHA and they were awesome, gave me every piece of info I needed. I contacted the breeders who were still listed as the owners. They were very understanding and just happy to hear the horse landed a good home and they just signed a new copy of the papers and a bill of sale. It was quick, simple and cost me just the transfer fee, granted I already had a membership with APHA.
