A bitter business divorce between San Antonio auto dealership partners has turned a once-successful partnership into a $20 million jury verdict, underscoring how partners can veer into conflicting paths with significant repercussions.
First things first: Abigail Kampmann and Mark Smith, who co-founded Principle Auto Group in 2014, expanded into several dealerships. But their relationship deteriorated in 2024 amid accusations of fraud, self-dealing, and breach of fiduciary duty, according to the San Antonio Express-News.
The central dispute involves real estate tied to BMW and Mini dealerships in San Antonio, which Smith claims Kampmann secretly controlled through shell companies, cutting him out of a lucrative business opportunity.
A North Texas jury recently sided with Smith, awarding him about $20.2 million, though the legal battle is ongoing, with more lawsuits pending and an appeal expected.
Meanwhile, both parties are trying to untangle and divide their shared business empire.
What they’re saying: “At the end of the day, these two partners need to have full separation, and I think we’ll get there,” said Kenny Meixelsperger, a Dallas lawyer representing Smith, per the Express-News. “How long it takes, I don’t know. But my hope is, in short order, we can find a way to get this business divorce finalized and let them go on with owning and managing the dealerships that they each have.”

Why it matters: This case is a reminder that partnership disputes can become expensive, distracting, and operationally disruptive very quickly.
Clear agreements around ownership, decision-making, compensation, and exit terms can be just as critical as the growth strategy itself.
Between the lines: The case adds to another concern around business partnerships, which is that about 70% fail, according to a recent Legal GPS analysis that identified “five fatal flaws” behind many breakups.
That’s a notable warning as partnerships in auto retail accelerate.
For example, unclear roles and responsibilities create confusion and conflict when partners fail to define who is responsible for what, leading to overlapping efforts and neglected tasks.
Misaligned financial expectations create tension when partners do not openly agree on profit distribution, expense responsibilities, and how differing contributions of time, money, and effort will be compensated.
Poor communication systems allow misunderstandings to build over time when partners rely on informal or inconsistent communication instead of clear processes for sharing information and making decisions.
The absence of exit strategies can make dissolving a partnership difficult and damaging, especially when partners have not planned for separation, disability, retirement, or unexpected life changes.
Incompatible work styles and values can create ongoing friction when partners differ in work ethic, risk tolerance, decision-making, and overall business philosophy.
Bottom line: A strong dealership partnership needs more than shared ambition. For dealers considering a partnership or expansion, the bigger takeaway is to put legal, financial, and governance protections in place early to reduce the risk of costly fallout later.
