Okla. Stat. tit. 19, § 19-62: Method of division - Agreements as to division

For the purpose of this article, the property, assets and

liabilities of the counties, as referred to in the preceding

section, at the time of the admission of the state into the Union,

shall be deemed the property, assets and liabilities of the original

county or counties in Oklahoma Territory, and the new county or

counties created, in whole or in part out of such original county or

counties; and the decree of the Supreme Court in all such actions

shall be based, as near as may be, upon the fair and reasonable

value of such of the property and assets belonging to such counties,

and the taxable value of the property in the counties, or parts of

counties, affected by such divisions or distribution, so that each

county shall be charged with liability and awarded assets in the

proportion which the taxable value of its property bears to the

taxable value of other counties affected by and interested with it

in the divisions and distribution of property, assets and

liabilities, as shown by the tax rolls for the year 1907; and such

decree shall be so framed as to fix and describe the assets awarded

to each county and the liabilities which shall be borne by it, and

determine whether such liabilities shall be borne by any such county

separately or jointly with another county, and determine the amount

and proportion of liabilities. All property of a permanent and

fixed nature, as mentioned herein, shall be decreed to and the title

thereto be vested in the county in which the same shall be situated:

Provided, however, that the board of county commissioners in any

such county are hereby authorized to confer and agree upon such a

division of any and all such property, assets and liabilities as may

to them seem just and equitable, and when such agreement shall have

been reached it shall be reduced to writing, subscribed by a

majority of the members of the board of county commissioners of each

of the counties that is a party to such agreement; and the same

shall be entered at length upon the records of the proceedings of

the board of county commissioners of the respective counties; a

certified copy of such agreement shall thereupon be transmitted by

one or more of the county clerks of any such county or counties to

the Clerk of the Supreme Court, within thirty days of the date of

such agreement; and the Supreme Court shall, thereupon, render a

final judgment decreeing the division and distribution of any and

all such assets and the apportionment of such liabilities according

to the terms of such agreement, and vesting the title to any

property mentioned in such agreement as therein provided; and such

judgment shall be final and conclusive in law and equity, and no

rehearing shall ever be allowed in any such case.
