Affidavit of heirship

In 2016 my aunt filled out an affidavit of heirship where she put that my deceased father, her brother didn’t have any children so she could sell the oil and mineral rights that have been in my family for decades in Oklahoma. After she died I filled for probate and was awarded her estate. So I’m wondering if I have the right to take the companies that bought the oil and mineral rights from her to court bc they didn’t do their diligence in making sure that the information on the affidavit was true? Also how can I legally put the remaining deeds in my name if the affidavit of heirship doesn’t reflect my name? The oil and mineral rights are in Oklahoma and the probate was awarded to me in Texas, where she resided. I really need some guidance on this matter any advice would be greatly appreciated.

You need Oklahoma counsel. A Texas court has no jurisdiction over oil & gas mineral rights in Oklahoma.

So it’s doable if I get a lawyer in Oklahoma? I am new to all this.

I would think so (he says reluctantly without looking at any documents.)

It all depends upon the chain of title on each mineral tract. You need a good estate attorney in Oklahoma. Good luck to you sir.

If she sold the mineral rights, then you would likely need a quiet title in county where the minerals were located. Sounds like a mess that will need some sorting out.

I agree with Mr. Winblad that something should be filed in the county where the minerals lie. Not sure where I got this, but I believe some states have a 10 year statute ?

If an Affidavit is not corrected or challenged, then after a certain amount of time it is assumed to be true.

She sold about 6500 acres to Cinco Energy land Service in Oklahoma. Would it be a good idea to reach out to Cinco energy about the incorrect information on the affidavit of heirship that my aunt used to sell? What will a quiet title do? Also what type of lawyer would I need to get a real estate lawyer or an oil and gas lawyer and what to expect if I was to get a lawyer? Do you have any recommendations for lawyers that have dealt with this before? I appreciate everyones help.

Not sure if the 6500 acres is both land and minerals, or minerals only. And I know nothing about Oklahoma law. But my sense is that first contact with Cinco should be through your attorney. I would want an O£G attorney with title opinion experience. You can help your attorney by providing him with all documents fully and quickly, and doing as much legwork as possible. The more support you provide the better your case will be and lower costs. Also, are there cousins involved to join in and split the costs?

I’m the only heir out of 3child which was my dad, his twin brother and his sister. No cousins also in probate I was awarded everything she owned. But before she died, she lied on an affidavit of heirship to sell mineral rights. These mineral rights were supposed to stay in the family, passed down to each generation but because she lied and said my dad didn’t have any children that’s how she was able to sell them.

You can observe qualified professionals (often with localized expertise) who provide services to mineral owners right here on The Mineral Rights Forum. You will notice them in 3 different places on the site:

  • in display image ads and text links on site

  • in our Mineral Service Provider Directory in the main navigation bar above. These are arranged by professional discipline.

  • as a Business Member within many conversations throughout the site Look for the blue colored “B” on their picture and blue colored text).

These practitioners are often able to provide specific (and often localized) services that meet your needs.

Great Advice, I would think that if the Affidavit of Heirship was incorrect then I would say the the title failed and the sale too.

Someone needs to challenge the Affidavit before it is is deemed to be accurate, due to lack of objections!

I agree with Benjamin , that if the affidavit stands unchallenged for the prescribed period of time, in may be accepted as validating title. Both land and minerals are subject to adverse possession in Texas. Maybe someone with experience in Oklahoma can speak to this.

In Oklahoma Section 67 - Acquiring a Severed Mineral Interest from Decedent - Establishing Marketable Title Cite as: 16 O.S. § 67, __ __
