Complete the jura/promesa (oath of fidelity to the King and obedience to the Constitution, art. 23 Código Civil) at the Registro Civil — must be done within 180 days of the grant notification or the concession lapses
The last formal act of becoming Spanish, exactly as the title describes: the oath of fidelity to the King and obedience to the Constitution, sworn at the Registro Civil. The title's deadline is the one thing to respect — the grant lapses if the jura isn't completed in its window after notification. After years of process, this one is an appointment and a sentence — enjoy it.
