Case – Griffin v. Griffin 2004 OK CIV APP 58 94 P.3d 96

Enforceability

The confusion concerning burden of proof arises primarily because antenuptial agreements, like contracts in general, “can be avoided by a showing of fraud, duress, coercion, overreaching, and the like.”

Fair Disclosure

If the antenuptial agreement is “apparently unfair on its face, equity raises a presumption against the validity thereof, and casts the burden upon . . . those claiming the validity of the contract to show that a full and fair disclosure was made to [the other party] of the extent and value of the property before [the other party] signed it, or that [the other party] was aware to all intents and purposes of the nature, character and value of the estate which she was relinquishing if the marriage took place.”
