Okla. Stat. tit. 52, § 52-570.11: Division orders

A division order is an instrument for the purpose of directing

the distribution of proceeds from the sale of oil, gas, casinghead

gas or other related hydrocarbons which warrants in writing the

division of interest and the name, address and tax identification

number of each interest owner with a provision requiring notice of

change of ownership. A division order is executed to enable the

first purchaser of the production or holder of proceeds to make

remittance of proceeds directly to the owners legally entitled

thereto and does not relieve the lessee of any liabilities or

obligations under the oil and gas lease. Terms of a division order

which conflict with the terms of any oil and gas lease are invalid,

unless previously agreed to by the affected parties. This

subsection shall only apply to division orders executed on or after

July 1, 1989.
