Registration with the Ameritano Horse Registry is based on documented parentage. If both parents qualify, your horse qualifies — there is no inspection and no conformation evaluation.
Does Your Horse Qualify?
Three conditions. Your horse must meet all of them.
- One parent is registered with the National Foundation Quarter Horse Association (NFQHA).
- The other parent is registered as a Lusitano with IALHA or APSL. If that parent is an IALHA S/P, it must be a minimum of 75% Lusitano — no more than 25% Andalusian.
- Parentage is verified. See the exception below, which applies to many horses.
An Iberian parent that is itself an Azteca does not qualify, because it already carries Quarter Horse blood. All Ameritanos qualify as Aztecas, but very few Aztecas qualify as Ameritanos.
Already registered with IALHA? You may not need testing.
If your horse has already been parentage verified and registered with a qualifying association such as IALHA or American Azteca, no additional UC Davis testing is required. Send us those papers together with the NFQHA papers and that is sufficient.
If your horse has not been parentage verified, testing through UC Davis is required.
What to Submit
Copies of the front side of both parents’ registration papers, plus parentage verification unless the exception above applies.
Papers must be legible digital copies in PDF, JPG/JPEG or PNG format, up to 10 MB per file. The digital copies supplied by each association are ideal.
Cost and Processing
Registration is $30 per horse. You may submit up to ten horses on a single application, calculated per horse.
Start Your Registration
Registration is completed online. Have both sets of papers to hand before you begin.
Not Sure Whether Your Horse Qualifies?
Send us the papers and we will tell you. Questions about eligibility are welcome and there is no cost to ask — particularly if you are unsure about the Quarter Horse parent’s certification, which is the most common point of confusion.
