A high-profile divorce in Florida is heading toward a contentious legal showdown, as healthcare investor Miguel “Mike” Fernandez seeks to enforce a decades-old prenuptial agreement against his wife of 25 years, Constance Tolevich Fernandez.
Fernandez, 73, chairman of MBF Healthcare Partners and a prominent Miami philanthropist, filed for divorce last month. At the center of the dispute is a prenup signed on the couple’s 2001 wedding day—an agreement he says limits his wife’s entitlement to a $1 million lump sum.
Constance Fernandez, 61, is contesting the validity of that agreement. According to statements from her legal team, she argues the document was presented under questionable circumstances, alleging she did not fully understand its terms or review financial disclosures before signing.
Mike Fernandez’s attorney, Raymond Rafool, rejects those claims. He maintains the prenup was discussed for months prior to the wedding and that Constance had ample opportunity to review it. Court filings assert she neither objected to the terms nor requested independent legal counsel at the time.
“The agreement was the foundation of their marriage,” Rafool said, adding that Fernandez would not have married without it.

The divorce petition, reviewed by media outlets, portrays Constance Fernandez as an experienced business professional and alleges she concealed past financial issues during their courtship—claims her attorney, Ana Martin-Lavielle, calls “unsubstantiated” and misleading.
Martin-Lavielle emphasized her client’s intention to handle the matter privately and with dignity, declining to address specific allegations out of respect for the couple’s children and long-standing relationship.
In addition to enforcing the prenup, Mike Fernandez is seeking sole ownership of the couple’s waterfront estate in Coral Gables, a property emblematic of the wealth they accumulated during their marriage.
Over the course of their relationship, the couple built a life marked by significant wealth and philanthropy. Court documents cite more than $10 million in assets and gifts provided to Constance, along with luxury holdings including a private jet, high-end vehicles, and multimillion-dollar jewelry collections.
Despite efforts to resolve the split privately—including offers of additional financial support and alternative housing—negotiations have failed, pushing the dispute into court.
A hearing is scheduled for early June, where a judge will begin weighing the enforceability of the prenup—an issue likely to determine the financial outcome of the divorce.
Legal experts note that courts closely scrutinize such agreements, particularly when claims of coercion or lack of disclosure are raised. The outcome could hinge on whether the court finds the agreement was entered into voluntarily and with full understanding by both parties.
For now, a marriage that once symbolized wealth and influence in South Florida has become a legal battle over fairness, disclosure, and the limits of a contract signed more than two decades ago.
