If your Application for Registration is complete when it arrives at the ILR, you should receive it back in ten to fifteen days.
Incomplete applications can result in unnecessarily long delays.
It often can be a hassle to obtain the signature of the sire's owner. The best way to avoid the problem is to get an Application for Registration form signed when you have the breeding done and fill in the particulars when the cria is born. If you do have to go back to a previous owner for a signature, you can send him or her a copy of the application and have it returned directly to you. You can then send it to the ILR yourself, so you'll know for sure when and if it was sent. Lack of bloodtyping information is another cause of delay.
