Property that is exempt by filing a claim may be claimed within the time and in the manner prescribed in the applicable enforcement procedure, and if not so claimed, the exemption is waived. (CCP 703.030) However, the court does have authority to grant relief from a failure to file a timely and proper claim of exemption. (CCP 473) Therefor, if a claim is submitted beyond the statutory time accompanied by a certified court order allowing the claim, it shall be accepted so long as the lien is in place or property remains in the custody of the levying officer.
