Okla. Stat. tit. 11, § 11-17-211: Expenditure of funds - Balances to be carried forward -

Unlawful acts and liability therefor.

A. No expenditure may be incurred or made by any officer or

employee which exceeds the fund balance for any fund. Any fund

balance remaining in a fund at the end of the fiscal year shall be

carried forward to the credit of the fund for the next fiscal year.

No expenditure may be authorized or made by any officer or employee

which exceeds the appropriation of any fund.

B. It shall be unlawful for any officer or employee of the

municipality in any budget year:

1. To create or authorize creation of a deficit in any fund; or

2. To authorize, make or incur expenditures in excess of ninety

percent (90%) of the appropriation for any fund of the budget as

adopted or amended until revenues received, including the prior

fiscal year's fund balance carried forward, totals an amount equal

to at least ninety percent (90%) of the appropriation for the fund.

Expenditures may then be made and authorized so long as any

expenditure does not exceed any fund balance.

C. Any obligation that is contracted or authorized by any

officer or employee in violation of this act shall become the

obligation of the officer or employee himself and shall not be valid

or enforceable against the municipality. Any officer or employee

who violates this act shall forfeit his office or position and shall

be subject to such civil and criminal punishments as are provided by

law. Any obligation, authorization for expenditure or expenditure

made in violation of this act shall be illegal and void.
