W. Va. Code § 37-1-2

If the guardian of any minor, or the committee of any insane person or convict, think that the interest of the ward or insane person or convict will be promoted by a lease or by a mortgage or by a trust deed upon or by a sale of his estates, or of an estate in which he is interested with others, infants or adults; or if the trustee of any estate, or any person interested in any estate in trust, whether he be interested with others or not, think the interest of those for whom the estate is held will be promoted by a lease of the same, mortgage or trust deed upon the same, or a sale thereof; such guardian, committee, trustee, or beneficiary, whether the estate of the minor or insane person or convict, or any of the persons interested, be absolute or limited, and whether there be or be not limited thereon any other estate, vested or contingent, and whether the guardian, committee or trustee, or the minor, insane person, convict, or any of the persons interested, reside in this state or not, may, for the purpose of obtaining such sale, lease, mortgage or trust deed, file a bill in equity in the circuit court of the county in which the estate proposed to be leased, sold or encumbered by mortgage or trust deed or some part thereof may be, stating plainly all of the estate, real and personal, belonging to such infant or insane person or convict, or so held in trust, and all of the facts calculated to show the propriety of the sale, lease, mortgage, or trust deed. The bill shall be verified by the oath of the plaintiff; and the infant or insane person or convict, or the beneficiaries in such trust, when not plaintiffs, and all others interested, shall be made defendants. The word "lease" as used in this article shall include any mining or timber lease or any lease of any profit in land, and the word "sale" shall include the sale of any undivided interest, or any part of the corpus of land, or anything in or growing upon land.
