The Crown reserved for itself important tools of intervention. The "capitulacion" clearly stated that the conquered territories belonged to the Crown, not to the individual. On the other hand, "concessions" allowed the Crown to guide the Companies conquests to certain territories, depending on their interests. In addition, the leader of the expedition received clear instructions about their duties towards the army, the native population, the type of military action. A written report about the results was mandatory. The army had a royal official, the "veedor". The "veedor" or notary, ensured they complied with orders and instructions and preserved the King's share of the booty.
