The levying officer shall tender the amount deposited by the redemptioner to the purchaser. (CCP 729.080(b))
If the purchaser and the person seeking to redeem the property disagree on the redemption price or as to whether the person is entitled to redeem the property, or if the purchaser refuses the levying officer’s tender of the redemptioner’s deposit, then the person seeking to redeem may file a petition with the court for an order determining the redemption price or whether the person is entitled to redeem the property. The petition must be filed within the redemption period. Written notice of the filing of the petition and a deposit of the undisputed amount of the redemption period must be given to the levying officer within the redemption period. At the hearing on the petition, the court shall determine by order the amount required to redeem the property. If the amount deposited with the levying officer is not sufficient to redeem the property, the person seeking to redeem shall, within 10 days after the issuance of the order, deposit the additional amount required with the levying officer.
