Circuit courts in the exercise of their equity jurisdiction, upon being satisfied by competent evidence independent of the admissions in the pleadings or elsewhere in the proceedings, that one or more of the types of relief hereinafter specified will promote the interest of an owner of land, or any interest therein, who is a person under a disability as defined in this chapter for whom a conservator has not been appointed pursuant to Chapter 20 (§ 64.2-2000 et seq.) of Title 64.2, and taking into consideration the rights of any other party interested in such land, may order the sale, exchange, lease, encumbrance, redemption, or other disposition of such real estate as to the court may seem just and equitable. In the case of the sales of such lands or interest therein, the court shall be governed by the established practices for judicial sales generally except as they may be specifically modified by provisions of this article.
