Must ex-spouses disclose dating relationships during divorce settlement negotiations? Miner v. Miner Explained

In Miner v. Miner, the Utah Court of Appeals addressed whether former spouses have a duty to disclose romantic relationships during post-divorce settlement negotiations. The case provides important guidance on the boundaries of disclosure obligations between litigation adversaries in family law contexts.

Background and Facts

John and Lisa Miner participated in mediation to resolve post-divorce disputes, including John’s $18,690 monthly alimony obligation and a substantial tax liability. During the September 7, 2022 mediation, Lisa agreed to accept only $1,000 per month in alimony in exchange for John assuming the entire $893,000 tax obligation. The court entered a modified decree on September 23. However, Lisa remarried just one week later on September 30, automatically terminating John’s alimony obligation. John claimed he learned of Lisa’s marriage plans only after the fact and filed a rule 60(b)(3) motion to set aside the decree based on fraudulent nondisclosure.

Key Legal Issues

The primary issue was whether Lisa had a common-law duty to disclose information about her romantic relationship during settlement negotiations. John argued that Lisa leveraged her willingness to reduce alimony while knowing she would soon remarry, effectively trading a valueless concession for substantial tax relief. The court also addressed whether John’s rule 60(b) motion qualified as an action “to establish” an order under Utah’s family law attorney fees statute.

Court’s Analysis and Holding

The court applied the fraudulent nondisclosure framework, which requires proving by clear and convincing evidence that the defendant had a legal duty to communicate information. The court emphasized that duty determinations depend on “all the circumstances of the case,” including the parties’ relationship structure, relative bargaining power, and available alternatives for obtaining information. Here, John and Lisa were litigation adversaries with contrary interests, both represented by counsel, with no fiduciary relationship. Crucially, John had adequate discovery tools available but failed to inquire about Lisa’s relationship status before mediation. The court declined to impose a common-law duty that would “upset settled expectations around litigation” and transform discovery disputes into torts.

Practice Implications

This decision reinforces that discovery rules, not common-law tort duties, generally govern disclosure obligations between litigation opponents. Practitioners should use formal discovery procedures to obtain information material to settlement negotiations, particularly regarding circumstances that could affect ongoing obligations like alimony. The court also clarified that rule 60(b) motions can constitute actions “to establish” orders under the attorney fees statute, but courts must still make detailed findings regarding financial need and ability to pay before awarding fees.
