21. Where the contributor dies before all the payments for the redemption of any period of service have been made, those payments are deemed to have been effectively remitted to Retraite Québec for the purposes of this plan.
Notwithstanding the foregoing, where, on that date, an amount payable by the contributor is due and exigible, Retraite Québec shall, if the amount including the interest provided for in section 25 is not paid immediately by the contributor’s personal representative or, after having been enjoined to do so, by the contributor’s spouse and children eligible for an allowance under this plan, deduct that amount by withholding a lump sum or periodic payments from such allowances, without prejudice to any other recourse available to Retraite Québec with respect to recovery.
