KERN, Retired Justice [¶1.] Bill Thovson, a South Dakota resident, contacted attorney Seamus Culhane, a South Dakota attorney, following the tragic death of Thovson’s wife, Paula, as a result of a car accident in North Dakota on July 28, 2020. Culhane agreed to represent Thovson and his minor daughter in relation to Paula’s death and the parties signed a legal services agreement establishing a one-third contingent fee. Shortly thereafter, Culhane recruited Thomas Dickson, a North Dakota trial attorney, to assist. The parties signed a second legal services agreement establishing that the one-third contingent fee would be split equally between Culhane and Dickson (collectively Attorneys). Both agreements permitted Attorneys to withdraw from representation and file a lien for the full amount of their contingent fee in the event that Thovson refused to accept a settlement offer that Attorneys considered reasonable. [¶2.] Within one month of Paula’s death, the at-fault driver’s and vehicle owner’s insurer tendered the policy limits on both policies for a total of $500,000. With the hope of recovering a larger sum, Attorneys and Thovson continued to look for additional assets and potential sources of recovery but were ultimately unsuccessful. Attorneys advised Thovson in November 2020 that settlement was the best option. Thovson declined to accept the settlement at that time. Attorneys provided notice of their withdrawal in January 2021 and filed an attorney’s lien in the amount of $170,049.81 representing one-third of the $500,000 settlement offer, plus costs. Eighteen months later, in July 2022, Thovson accepted the insurer’s settlement offer and Attorneys brought suit against Thovson, seeking a declaratory

judgment enforcing their attorney’s lien and alleging breach of contract. Thovson counterclaimed for fraud, recission, breach of fiduciary duty, breach of contract, and deceit, relying in part on North Dakota law. [¶3.] Following discovery, the parties filed cross-motions for summary judgment. The circuit court granted Attorneys’ motion for summary judgment on their claims and ordered Thovson to pay Attorneys’ fees and costs plus $31,303.59 in prejudgment interest. The court also granted Attorneys’ motion for summary judgment on Thovson’s counterclaims, which were dismissed. Further, the court held that North Dakota law did not apply, but that even if it did, Thovson failed to provide notice of recission within the statutory timeframe required under North Dakota law in order to void the agreement. Thovson appeals. We affirm in part, reverse in part, and remand for a determination of Attorneys’ reasonable fees based on quantum meruit.
