Its a tricky situation. The AMHA closed for hardship so if the stud is not able to be papered like disneyhorse said then no, the colt cant be reg. with the AMHA. With the AMHR, if the sire cannot be reg, but the dam is AMHR, you could get sport performance papers for him. Its hard b/c both parents need to be papered in order to paper offspring with the AMHA & AMHR. You could ask the breeder if they can get the sire registered first but thats pretty much it. Sorry.
