• The province will vote with the traditional boleta partidaria, while the national elections on October 26 will use the Boleta Única de Papel.
• Under Law 5.109, impugned ballots require fingerprint expert verification before being counted, and there is no separate 'voto nulo' category as in national contests.
• The veda electoral begins Friday, September 5 at 08:00 and runs until Sunday at 21:00, restricting campaigning, poll publication and certain activities such as alcohol sales from Saturday evening.
• Voting is compulsory for citizens aged 18–70 and voluntary for 16–17 and over 70; outlets report conflicting fine amounts for non‑voters, classes resume normally on Monday, September 8, and initial results are expected after 21:00 on election night.
