After her brother Levi died intestate in 1874, Lois filed an order for administering his estate. She state that as his sister she was his only living nest of kin, having been associated with Levi Deming "during the past thirty-eight years as sister and house-keeper and intimate friend. He lived and died unmarried and single, without issue of offspring. Father, mother, brother and sisters all dead". Harmon S. Barnum, Lois' son, tried to defraud his mother of part of her inheritance by means of a false, pre-dated paper supposedly signed by Levi and granting to Harmon one-half of the property known as Cottage Farm. The Supreme Court of Virginia found this to be an incredible claim, since Levi Deming "barely endured his nephew".
Harmon then filed a false deed to the property in the name of George A. Mushbach, an attorney and a comparative stranger, who deeded the property back to Harmon on 3 June 1874 for a payment of $5 and Harmon took up residence on Cottage Farm.
On 14 June Lois made her will, leaving everything to her daughter Eunice, ignoring her other three children. On August 14 she filed an order to administer Levi Deming's estate and on 13 February 1878 she filed suit in Fairfax Circuit Court seeking to void the previous illegal property division. Over the next few years the case passed through several suits, counter suits and appeals until finally, on 28 April 1887, the Virginia Supreme Court of Appeals brought a conclusion to the case by finding in favor of Lois. The Court stated in its final opinion that the record, "discloses a case of as gross and transparent a purpose on the part of Harmon S. Barnum to defraud his mother, as we have ever seen".
