Okla. Stat. tit. 84 § 221
Current through Laws 2024, c. 453.
In the collateral line the degrees are counted by generations, from one of the relations up to the common ancestor, and from the common ancestor to the other relations. In such computation the decedent is excluded, the relative included, and the ancestor counted but once. Thus brothers are related in the second degree, uncle and nephew in the third degree, cousins german in the fourth degree, and so on.
