Okla. Stat. tit. 11, § 11-37-233: Right of action of bondholder

Any holder of any improvement bond issued hereunder shall have

the right to institute, in the name of the municipality issuing the

bond, an action in the district court in the county in which the

property is located to foreclose the lien of the assessments

whenever the assessments, or any installment thereof, are delinquent

for a period of at least six (6) months. The petition for

foreclosure shall generally:

1. State the ownership of the bond;

2. Describe the property assessed;

3. Describe the nature of the improvement;

4. Set forth the amount of the unpaid delinquent assessment or

installment and penalty thereon at the rate of twelve percent (12%)

per annum; and

5. Pray for the foreclosure of the lien.

Summons shall be issued on the petition as in other civil actions

and the cause tried by the district court. Judgment may be entered

on the petition for the amount of the unpaid assessment, or

installment, together with interest thereon at the rate of twelve

percent (12%) per annum from the date the assessment or installment

was due and payable up to the date of the filing of the petition,

and for the sum of six percent (6%) interest on the judgment

computed from the time of filing the petition until the judgment is

paid, together with reasonable attorneys fees. If the judgment,

together with interest, costs and attorneys fees, is not paid within

six (6) months after the date of the rendition thereof, an order of

sale shall issue by the clerk of the court, directed to the sheriff

of the county, to sell the real estate in the manner and form as for

sale of real estate under execution. Upon the payment of the

judgment, the amount thereof exclusive of costs and attorneys fees

shall be paid to the municipal treasurer for deposit in the

separate, special fund to pay outstanding bonds and interest

thereon. The judgment shall provide for the sale of the real estate

subject to existing general ad valorem taxes. All owners or

encumbrancers shall be made parties defendant in the suit. Upon the

institution of an action to collect delinquent and unpaid

assessments in any improvement district against property liable

therefor, no other or further action shall be instituted and

maintained to collect such delinquent assessment against the

property for that year.
