Mayor Rodrigo Duterte's son and Vice Mayor Sara's brother Paolo is running as chair of Barangay Catalunan Grande, a barangay in Talomo district with 9,000 registered voters.
The younger Duterte, earlier touted as heir to his father's hold on Davao City's politics, runs opposite four other candidates, according to the Commission on Elections Sunday.
Lacsasa Casar, election officer for another district, said it is confirmed that the mayor's eldest child is batting for the village chief position.
The office of the election officer of District 1, where Catalunan Grande, Talomo, belongs, could not be reached by telephone.
The office of Catalunan Grande incumbent barangay chairman Jesus Sabio confirmed the younger Duterte filed his candidacy for the post, on October 19.
Dodong Arnaiz a staffer of Sabio at the barangay hall, told MindaNews via telephone there is no question about the younger Duterte's residency as he lives in Monte Maria Village.
Sabio is not seeking reelection. Duterte's four opponents are businessman Rudy Abella, former barangay kagawads Minda Rodriguez and Tata Kurato, and incumbent kagawad Dodong Ambe.
If he wins, Duterte could also bat for the presidency of the 184-member Association of Barangay Councils, which would make him an ex-officio member of the city council presided by his younger vice mayor-sister.
Earlier reports in the media said Paolo's move surprised the barangay and even the officials of his father's Hugpong Party.
Catalunan Grande is one of the 54 barangays in Davao City's first congressional district, which covers the downtown area where House Majority Floor Leader Prospero Nograles is the incumbent congressman.
