Real estate ownership—whether with a spouse, family member, friend, or business partner—can become a financial minefield if the parties fail to document their rights and obligations. A recent appellate case, Lantz v. Gibson, illustrates how even well-intentioned co-owners can wind up in years of litigation simply because they lacked a properly drafted property agreement. The case offers critical lessons for landlords, investors, and anyone holding title with another person. Below is a summary of the case and the key takeaways for property owners who want to avoid the same fate.
Case Breakdown: When Divorced Co-Owners Disagree Over 17 Years of Expenses
The Facts: A Marital Settlement Agreement That Missed Everything Important
Jeanine Rochelle Lantz (“Lantz”) and Shawn Jeremy Gibson (“Gibson”) bought a home together in 2005 while married. When they divorced in 2007, their final judgment incorporated a self-drafted marital settlement agreement (“MSA”). That agreement contained two relevant provisions:
- If the home was later sold, they would divide proceeds 60% to Lantz and 40% to Gibson.
- Lantz would be solely responsible for the mortgage and would not seek contribution from Gibson.
However, the MSA said nothing about other expenses: taxes, insurance, repairs, maintenance, vacancy losses, or rental income.
For the next 17 years, Lantz rented the home to third parties and collected all rent. During that entire time, she paid all home-related expenses on her own. Gibson never contributed; Lantz never shared rental income.
In 2021, the parties contracted to sell the property. When Lantz learned Gibson would receive 40% of the net proceeds, she refused to close and instead filed a partition action seeking:
- Partition by sale, and
- Reimbursement for 17 years of property expenses.
Trial Court: No Reimbursement Because the Agreement Didn’t Say So
The judge denied Lantz reimbursement, reasoning that the MSA did not expressly provide for such credits and that the court would not “create terms the parties never agreed upon.”
Appellate Court: Reversed—Silence Doesn’t Release Co-Owners From Expenses
The First District Court of Appeal reversed. The appellate court held:
- Upon divorce, the property automatically became a tenancy in common.
- As tenants in common, each party remains responsible for their share of property-preserving expenses, unless a written agreement says otherwise.
- The MSA relieved Gibson only from mortgage-related expenses, not from all other categories of expenses.
Because the MSA was silent on taxes, insurance, maintenance, and repairs, Gibson was still legally responsible for a share of those expenses regardless of the parties’ assumptions or informal practices.
The court remanded the case for a full accounting, including offsets for rents Lantz collected exclusively. In fact, the court noted it could not say whether Lantz would ultimately receive anything after rental income and expenses were reconciled.
5 Critical Lessons for Florida Co-Owners From Lantz v. Gibson
1. Silence in an Agreement Is Not Neutral—It Creates Risk.
One of the biggest problems in Lantz is that the parties drafted their own agreement and failed to address critical financial terms. The MSA assigned the mortgage to Lantz, but it never addressed:
- Taxes
- Insurance
- Repairs
- Capital improvements
- Rent collection
- Profit sharing
- Management authority
- Rights to occupy the property
That silence left the parties at the mercy of Florida’s default co-tenancy rules, a costly outcome that could have been avoided with professional drafting.
2. Co-Ownership Without a Written Expense and Income Agreement Is Financially Dangerous.
Under Florida law, co-owners must contribute proportionately to expenses unless expressly released. They also must account to one another for rents and profits.
3. Partition Actions Are Complex and Can Produce Unpredictable Results.
Partition is not simply a court-ordered sale. It typically requires the court to determine ownership shares, assess claims for reimbursements or credits, calculate offsets for rental income and exclusive possession, and allocate net proceeds.
4. Self-Drafted Agreements Are Historically High-Risk in Real Estate.
The parties in Lantz drafted their own MSA, leading to ambiguity, missing terms, and years of incorrect assumptions.
5. The Right Attorney Can Prevent or Fix These Problems.
A property law attorney can draft a comprehensive Property Rights & Obligations Agreement and represent clients in partition actions where accounting and legal strategy are essential.
Bottom Line: FL Co-Owners Must Document Everything or Risk Losing Everything
Lantz v. Gibson shows how misunderstanding, inadequate documentation, and poorly drafted agreements can culminate in expensive litigation. Co-owners who fail to define their obligations risk losing significant equity and becoming trapped in disputes that could have been avoided. If you own property jointly—or plan to—protect yourself by hiring a qualified property law attorney to draft the correct agreements and represent you in any division or partition of property.
