I know in Texas you can apply for a bonded title, if nobody contests it in 3 years they issue you a clear title. Since there is murkiness around this, why not go this route? Since you have the quasi-title you should be ok no?

You can do bonded titles in OK, but like you say, it's merely an insurance policy for a three year period, allowing registration only, but the murkiness surrounding this deal negates the possibility.
Clear title issuance isn't until the end of the three year period, if uncontested, and still requires the current titleholder being served.
Sounds OK, right?
Remember, the titleholder and signer is the deceased father of seller, therefore I'd be bonding a title and investing money into a vehicle that has, "dead Indian potential", a term used to express possible claims by heirs, known or unknown, on land dealings here in OK.
Pretty much, if one survivor of an heir liquidates what was stipulated as Indian land, yet unpaid heirs existed (now descendants two/three times removed. All of this made possible by a litigious society and attorneys who like easy money) regardless of the fact that you hold title, it's not deemed clear.
Title insurance on land is a serious affair in OK, to say the least, and that's all a bonded title is. Insurance that no heirs will demand retribution during the three year period.
Here's the scenario. Invest cash into it and two years, nine months later an heir contest the original sale, I'm screwed, no ifs, ands, or buts about it, since legally the seller isn't the titleholder.
Other investigated option is a court order for the OK DMV to issue a clear title, in my name, after a factual outlay of all information possible, which may or may not have criminal implications (If the title had been certified mailed, it'd be a different story. ALWAYS USE CERTIFIED MAIL FOR TITLES YOU CAN'T INSPECT.) since a case of fraud, regardless of intent or malice.
Again, the titleholder has to be named on the affidavit and served as the title holder, which isn't a possibility since titleholder and signer is deceased, so more legal wrangling, it's an expensive proposition. Filing fees, legal fees, documentation fees, third party servers, could all easily add up to more than I paid for the vehicle, forcing punitive damages being sought to cover the expenses incurred, again from a seller whose not the titleholder, so next best thing, a mother who has absolutely no involvement.
I do not wish to seek retribution at this point, therefore I don't want to incur expenses that would necessitate, but have a fair timeline in mind to get this taken care of, considering its now been a known issue for almost a month.
At the advice of counsel, the only means to not incur expenses that would demand and a case be made for punitive damages, since estimates exceed the purchase price of vehicle, is for seller to produce a valid duplicate title.
I just want a friggin title I can transfer that was presented as part of the deal, and get on with it.
No hokey crap, no legal wrangling, just a friggin duplicate title.
