For the year 1912 in my Great Grandfathers Civil Guard records there are two entries.
Here is the second one (start 1913 later - has 3 notes):
I thought that this note might have a baring on the first note (the Judicial stuff).
Transcribed text so far:
El dia 11 de Agosto año marginal, se incogono al puerto de Corcoya para puesta el servicio de el clase, al que fue destinado por orden del Señor primer (1ª) Jefe de la Comandancia donde finio el ano.
El 2º Jefe
I don't know if my efforts are accurate? I don't see any references to judges here but I do note he has now moved from Herrera to Corcoya. Might be related?
I tried to see if there was a Civil Guard office in Corcoya still but I could not find one. Only the one in Herrera so far.
Translation based on provided answer:
On the 11th of August of the marginal year, he joined the Corcoya post to render the service of his class, to which he was assigned by order of the 1st Chief of the Command where he finished the year.
The 2nd Chief
