Your account may be in suspense for one of the following reasons:
- Title requirement
- Address unknown
- Uncashed revenue check
- The revenue accrued is under the minimum release threshold per applicable state statute
Following a well’s first production, a revenue check will be issued within the state’s applicable statutory period regarding initial production revenue disbursement, assuming none of the above apply.
If you determine there are discrepancies with how your interest has been calculated, please provide in writing a full explanation of how you believe your interest should be calculated along with the supporting documentation to:
Casillas Petroleum Corp.
P.O. Box 3411
Tulsa, OK 74101Or you may email us at owner.relations@casillaspetro.com
A change in a life situation may result in either a change of ownership or a change to an owner’s payment status. Should one of those situations occur, we may require documentation to effectuate the change. Please note that certain jurisdictions may have differing legal requirements and additional documentation may be required. We will not accept unrecorded copies of conveyance document to process changes in ownership. However, upon request we will suspend the interest being conveyed until recorded documents are received.
TRUSTS:
Provide a recorded copy of the Memorandum of Trust as well as recorded conveyance documents into the trust. Alternatively, if a trust is dissolved, provide a copy of the dissolution document and appropriate recorded conveyances
DEATH:
1) By testate succession (Last Will & Testament of deceased owner has been probated in a district court of the state where the property is located) – Provide a copy of the final distribution of the estate, recorded in the county and state where the property is located along with names, current addresses and Tax ID’s of devisees.
**Some states (including Oklahoma) do not accept probate from other states to transfer title on real property. Ancillary probate is the only means of passing marketable title when a will has been probated in another state.
2) By intestate succession (in the absence of a will or the will is not probated, the property will be distributed according to the Laws of Descent and Distribution for the State in which the property is located). Provide a properly executed and recorded Affidavit of Heirship*** (AOH). AOH’s CANNOT be completed by an heir/devisee of the deceased. They must be completed by someone who knew the deceased and has knowledge of the family history.
***We will review each account, on a case by case basis, to determine if Casillas will accept an Affidavit of Heirship to distribute property. There will be times that Casillas will require the estate be probated even if there is not a will to provide minimal business risk to the company.
Please consult with a qualified legal representative if you have questions.
Transfers are processed in the order in which they are received. Our goal is to have the transfers processed within 45 days.
Upon completion of a transfer, an amended division order will be issued/mailed reflecting this change. If you have not received a division order after 60 days, please contact our office at (918) 582-5310 or owner.relations@casillaspetro.com
If you haven’t received your payment and it has been at least 20 days since issuance, contact the Revenue Department at (918) 582-5310. The payment can be voided and reissued on the next qualifying disbursement. We need to be aware that the payment is missing.
If your address has changed since the disbursement took place, contact us at the Owner Relations number listed above. The payment can be voided and reissued on the next qualifying disbursement.
This can occur for numerous reasons, including:
Other factors possibly causing variances between family member check amounts may be related to stale dated checks, returned checks and/or address changes
Mineral ownership between family members is not equal
The family members’ interests arise from different leases with different terms
Some family members may not have provided Casillas Petroleum Corp. with a Tax ID (TIN) or other required information
State withholding for family members residing in different states
Some family members may own interest in other properties in addition to those commonly owned
