La compra de sentencias consists of a procedure, where a private entity, assumes the position of a creditor of the debt or economic rights of judgment, whose beneficiary is a natural or legal person who has been a victim of both the omission and the action of the State. 

These private entities buy the economic rights to these rulings. They pay the beneficiary of the judicial sentence (Victim of the state), after a discount, and the private entity is the one who waits for the transfer from the state, while the beneficiary obtains his payment much faster.
