Detailed Answer

Short answer: if a recorded survey and chain of title show the property was lawfully conveyed out of your mother’s estate decades ago, you likely no longer have a legal interest in that property. But there are several important exceptions and practical steps you should take before concluding you have no claim.

Why a recorded conveyance matters

Recorded deeds and a clear chain of title are the primary public evidence of who owns real estate. When a deed was properly signed, witnessed (if required), and recorded, the new owner usually gains legal title. If the conveyance was part of a probate administration and the court approved it, that makes the transfer more secure.

Common reasons you might still have a claim

Forgery or fraud. If the deed was forged or procured by fraud, you can challenge it, even after many years.
Improper probate procedure. If the estate never had proper legal authority to convey (for example, there was no valid probate administration or the person who signed lacked authority), the conveyance could be voidable.
Clerical or recording errors. Mistakes in the deed, a missing signature, or a gap in the recorded chain can create problems that a title company or court can remedy.
Will or intestacy disputes. If the conveyance came from an estate distribution that wrongly excluded heirs, an heir might have a claim to set aside the transfer in some cases.
Equitable claims. Under limited circumstances (equitable estoppel, undue influence, or breach by an executor), courts can undo or adjust prior transfers.

Common reasons you probably have no interest

Long-ago, properly recorded sale or transfer by the decedent’s personal representative with court approval.
Subsequent bona fide purchaser. If a later owner bought the property in good faith and recorded the deed, courts generally protect that purchaser.
Adverse possession or statutes of limitations. If a third party occupied and used the land openly and continuously for the statutory period, they may have acquired title. (See Oklahoma statutes on limitations and property for details.)

What you should do next — step by step

Get copies of the recorded deed(s) and the survey. Check the recording dates and grantor/grantee names.
Obtain the probate file. Ask the probate court where your mother’s estate was opened (usually the county probate court) for the estate file. The file will show whether the court authorized sale or distribution of the property. Oklahoma decedents’ estates laws are codified at Title 58 of the Oklahoma Statutes: https://www.oklegislature.gov/Statutes/Title58/t58.htm.
Order a title search or contact a title company. A title search will identify breaks in the chain, liens, encumbrances, and whether the conveyance was recorded properly.
Check tax and possession history. See who paid property taxes and whether anyone has openly possessed the property. Oklahoma property and recording laws are in Title 60 (Property): https://www.oklegislature.gov/Statutes/Title60/t60.htm.
Consider limitations periods. Many claims (like quiet title or claims to set aside a conveyance) must be brought within a statutory period. Oklahoma’s statutes governing limitations and civil actions appear under Title 12: https://www.oklegislature.gov/Statutes/Title12/t12.htm. Talk to a lawyer promptly if you believe you may have a claim.
Talk to an attorney. If you find possible problems (forgery, no probate authority, or suspicious facts), you will need counsel who can advise whether to sue (for quiet title, to cancel a deed, or to pursue claims against an estate representative) and who can explain likely costs and timelines.

Possible legal remedies (depending on the facts)

Quiet title action — asks a court to declare who owns the property. Used when title is disputed.
Action to cancel or set aside a deed — used if the deed resulted from fraud, forgery, or lack of authority.
Claims against estate representatives — if an executor or administrator mismanaged estate assets, heirs can sometimes recover value from the personal representative’s estate or from the representative personally in cases of bad faith.
Equitable relief — in narrow situations courts may apply doctrines like undue influence, constructive trust, or equitable estoppel.

Practical outcomes you may face

If the conveyance was valid and recorded, you will likely have no legal interest and cannot reclaim the property.
If the conveyance was void or voidable (fraud, forgery, lack of authority), a court might cancel the deed and restore title or provide monetary relief.
If the matter is unclear, a negotiated solution (buyout, settlement, or partition of proceeds) may be faster and cheaper than litigation.

Where to find the records: county recorder (deeds), county probate court (estate files), and county tax assessor (tax payment history). For statutory law, see the Oklahoma Legislature: https://www.oklegislature.gov.

Important: statutes and procedures vary with the exact facts. Adverse possession, limitations periods, and probate rules can change available remedies and deadlines. Consult an attorney quickly if you suspect your rights are at issue.

Helpful Hints

Start by getting certified copies of any deeds, the survey, and the probate file. Accurate records make assessment faster.
Look for court orders in the probate file authorizing sale or distribution. A court order increases the chances the sale was valid.
Check whether anyone has paid property taxes and who has been in physical possession. Long-term possession can affect claims.
Contact a title company for a professional chain-of-title report. That report clarifies whether the recorded transfers created marketable title.
Ask an attorney whether the facts suggest fraud, forgery, lack of authority, or a recording error — these are the most common bases to challenge an old conveyance.
Act quickly. Even if you think you have a claim, statutes of limitation or laches may bar relief if you wait too long.
Keep your communications documented. Preserve emails, certified mail receipts, and copies of records you obtain.
If you cannot afford a private attorney, check for legal aid programs in Oklahoma or limited-scope help from local bar associations.
