Cal. Health & Safety Code § 7928

After making provisions for an endowment care fund to provide for maintenance and care, the governing body of the cemetery corporation or association may use such portion of the funds then remaining as it may determine to be just and fair in reimbursing those who voluntarily and at their own cost and expense removed the remains of friends or relatives from the cemetery lands from which the remains were ordered removed. Such reimbursement shall not be greater in amount than the average cost to the cemetery corporation or association for removals directly made by it.
