Ala. Code § 35-11-331: Enforcement of Lien.

For the enforcement of such lien the owner of any such animal may have process of attachment from any court having jurisdiction of the amount claimed, leviable on the animal or animals upon which the lien exists:

(1) When such claim is due, and the defendant, on demand fails or refuses to pay.

(2) Whether such sum is due or not, when the defendant has traded off or otherwise disposed of, or there is good reason to believe he is about to trade off or otherwise dispose of, or remove from the county, any of the animals on which the lien exists, without paying the stipulated price for such service.
