definitive title vs. concession

The first section of these regulations gives the authority to governors (gefe politico) to grant vacant lands… By the 4th section, the governor being thus informed may 'accede or not' to the prayer of the petition. This was done in two ways—sometimes he expressed his consent by merely writing the word 'concedo' at the bottom of the expediente; at other times it was expressed with more formality… But it seldom specified the boundaries, extent, or conditions of the grant. It is intended merely to show that the governor has 'acceded' to the request of the applicant, and as an order for a patent or definitive title in due form to be drawn out for execution. It is not itself such a document as is required by the 8th section, which directs 'that the definitive grant asked for being made, a document signed by the governor shall be given to serve as a title to the parties interested.
