Is it required to have Seller's Property Condition Disclosure?

[Andrea Tapp]

Hello,

We are writing up our first contract on an offer, and I had a question about the Property condition disclosure.  I would like to have the seller fill out the property condition disclosure, but is it required?  I ask because I do not have a copy.  Does anyone have access to a disclosure that we can have?  If it is state dependent we are in Oklahoma.

Thank you for your help!
