OPINION FILED 01/14/26

KERN, Retired Justice [¶1.] Martin Allen Webb (Butch), age 57, and Stephanie Eagleberger, age 29, planned to marry in 2013 after dating for nearly a year. Butch was a successful businessman and rancher in South Dakota, and Stephanie co-owned and operated a high-end horse breeding business in Colorado. At Butch’s request, his attorney, Eric Bogue (Eric), drafted a prenuptial agreement for his review. The proposed agreement, among other things, waived Stephanie’s right to claim any share of Butch’s estate after his death. Butch presented Stephanie with the agreement the day before their planned civil wedding ceremony, which was scheduled for the following evening at Eric’s law office. The parties signed the agreement shortly before the ceremony began, and the two were married on October 11, 2013. [¶2.] Butch died approximately eight years later. Stephanie petitioned the court for an elective share of Butch’s estate per SDCL 29A-2-201 and a family allowance under SDCL 29A-2-403, arguing that her signature on the prenuptial agreement was involuntarily made and that the agreement itself was unconscionable. After a trial on the matter, the court granted Stephanie’s request for a family allowance but denied her petition for an elective share. The court found Stephanie voluntarily signed the agreement, and that the agreement was not unconscionable. Stephanie appeals. We affirm.

Factual and Procedural History [¶3.] Butch Webb died on December 9, 2021, at the age of 65. At the time, he was married to Stephanie, who had been his wife since late 2013. Butch was nearly 30 years older than Stephanie at the time of their marriage, and this was a

second marriage for both parties. Throughout his life, Butch built a substantial career in the financial industry. Butch was college-educated with a bachelor’s degree from the University of Wyoming. He was the past president of a bank and a very successful businessman, accumulating significant wealth through payday lending businesses. In addition to his business ventures, he operated a sizeable ranching operation near Isabel, South Dakota, where he raised cattle and valuable horses. [¶4.] Stephanie lives in Loveland, Colorado. She graduated from high school in 2002 and has a bachelor’s degree in equine science with minors in agricultural and racehorse economics from Colorado State University. While in college, Stephanie started working for Royal Vista Equine, a high-end horse breeding business. She began as an undergraduate intern and was later “hired on to help sales prep racehorse yearlings” around 2006. The company employed 10 to 12 employees and was headquartered in Fort Collins, Colorado. She eventually became the office manager in 2007 after graduating from college. Her duties included oversight of client billing, entering into contracts with clients, and working with CPAs to do the year-end taxes. She has been in charge of “the books since [she] started working in the office in 2006.” [¶5.] While working for Royal Vista in 2007, Stephanie married Chris Kepplinger, her first husband. They separated in 2011 and divorced in 2012. The divorce did not involve attorneys and was described as amicable. Also in 2011, the owners of Royal Vista decided to retire and turned the business over to Stephanie and her business partner, Jake Dahl. Through this process, Stephanie acquired a

45% interest in Royal Vista Equine. She testified that the reason the previous owners chose to turn the business over to her instead of selling it was because she was good at what she did. After acquisition, Stephanie and Jake changed Royal Vista’s name to Vista Equine LLC. Her interest remained at 45%, and she continued in her role as office manager with a salary of $45,000 per year. [¶6.] Stephanie and Butch’s romantic relationship began in January 2013. Butch became a client of Vista Equine in 2007, but it was not until Stephanie began texting Butch about acquiring a brood mare in early 2013 that their friendship deepened. The two began texting and calling each other frequently, and their first date was February 11, 2013, where they met at a bull sale in Nebraska, and Butch asked Stephanie to join him for dinner. [¶7.] Stephanie testified that the couple “had so many similarities” and “looked at things the same way.” Their relationship “flowed” naturally despite the nearly 30-year age difference. Butch and Stephanie traveled to South Dakota for the first time together to visit Butch’s ranch and to meet his children and other family members in the spring of 2013. Butch was previously married and had four children from his first marriage and from another relationship: Dee, Deb, and two minor children. Dee Haugen, the oldest of Butch’s children, was 46 years of age at the time of trial. [¶8.] After a few months of dating, Butch proposed to Stephanie on May 16, 2013. Because Stephanie was not ready to move to South Dakota, Butch purchased a property in Loveland, Colorado, for her on May 20, 2013, titling it solely in her name. The property covers nearly 70 acres and was valued at $1.3 million in 2013.
