124.—(1) Subject to paragraph (2), where a liable relative makes a periodical payment concurrently with any other payment, and the weekly amount of the periodical payment as calculated in accordance with regulation 122(1) to (4) (calculation of the weekly amount of a liable relative payment) is equal to or greater than the amount referred to in sub-paragraph (a) of regulation 121(2) (period over which payments other than periodical payments are to be taken into account), less the £2 referred to therein, or sub-paragraph (b) of that regulation, as the case may be, the other payment shall be treated as capital.
(2) If, in any case, the liable relative ceases to make periodical payments, the other payment to which paragraph (1) applies shall be taken into account under paragraph (1) of regulation 121 but, notwithstanding paragraph (4) thereof, the period over which the payment is to be taken into account shall begin on the first day of the benefit week following the last one in which a periodical payment was taken into account.
