Okla. Stat. tit. 70, § 70-5-160: Interaccount and interfund transfers

The chief executive officer, or designee, as authorized by the

governing body, may transfer any unexpended and unencumbered

appropriation or any portion thereof from one account to another

within the same fund; except that no appropriation for debt service

or other appropriation required by law or regulation may be reduced

below the minimums required. Other interfund transfers may be made

only as authorized by this act or as provided in the budget as

adopted or amended according to this act. Whenever the necessity

for maintaining any special fund of a school district has ceased to

exist and a balance remains in the fund, the governing body may

authorize the transfer of the balance to the general fund.

Applicable law shall govern the use or transfer of any remaining

balance in any debt service or bond fund.
