Interpretation boundary
Uniform ancestry does not make state law uniform.
States amend model acts, courts interpret identical words differently, and enactment dates determine whether an older agreement falls under the current chapter. “Non-uniform” likewise does not mean unregulated. It means the current package routes research through state-specific statutes, cases, or mixed frameworks rather than a current UPAA or UPMAA enactment.
