Hi arkles
You won’t find any specific reference to the office of treasurer in the Act.
Only the offices of president, vice-president, secretary and administrator are dealt by the Horizontal Property Act. Nevertheless the last paragraph of section 13 (1) of the mentioned Act makes provision for ‘other governing bodies of the community’
‘The Articles of the commonhold association or a majority resolution from the Owners’ Committee may establish other governing bodies of the community, but only insofar as this does not entail any impairment whatsoever of the roles and duties regard to third parties that this Act confers to the aforementioned’(president, vice-president, secretary, administrator and the Owners’ Committee)
You should read the Articles (Estatutos) of your community or the minutes appointing the office of treasurer in order to find out if there is any restriction imposed to hold such office
