I'm not sure about what you mean by "allowed". Private sales are tricky things because they're not really governed by set rules.
There can be a rule about false advertising where a horse is misrepresented but I'm not sure that this is relevant in this case.
Buying horses is a lot about "buyer beware" where the buyer needs to take take the responsibility for ensuring the horse is what they want through vet checks or other expert opinions. This is compared to other forms of retail such as shops where they are required to sell things to a certain standard as described and expected.
The time to make sure everything is right is just before you hand over the money. If you're not happy call the previous owner and ask for them to take back the horses and refund your money. If you have a payment plan hopefully you wrote up an agreement to go with it, see how it describes the horses and if it makes any guarantees.
