One. The fees and contributions from members and supporters must be paid into accounts held with financial institutions which have been opened exclusively for that purpose. The payments made into these accounts can only be for said fees, and they must be made through direct debit from an account whose title holder is the member, or by means of a transfer to the account designated by the political party which must bear the member's name.
Two. Other private contributions must be paid into a different bank account from the one mentioned in the previous paragraph. In any case, a record must be kept of the date of the deposit, the amount of the deposit and the full name of the member or the payer. The financial entity where the deposit is made shall be obliged to issue a document confirming the above-mentioned details.
