Vermont's marketable title act, Vt. Stat. tit. 27, §604(a), allows preservation of claims established more than forty years ago if they are re-recorded but does not require easements to be re-recorded if they are visible or evidenced by a "recorded agreement." In Gray v. Treder, 2018 VT 137, 2018 Vt. LEXIS 237 (Vt. 2018), the Vermont Supreme Court held that easements by necessity fit into neither of those categories and thus need to be re-recorded every forty years to preserve them.
While the case resulted in a landlocked parcel, the Court found the statutory policies of clearing title to be more important than ensuring access to a landlocked parcel.
