The Law Firm of Jeffrey Alan Aenlle, PLLC is a boutique divorce and family law firm located at 1221 Brickell Avenue, Suite 900, Miami, Florida 33131 – directly accessible from Key Biscayne via the Rickenbacker Causeway. We represent individuals and families in divorce, child custody, alimony, child support, paternity, and prenuptial agreements throughout Miami-Dade County.
Key Biscayne is one of Miami-Dade’s most exclusive island communities, home to a significant population of international residents, diplomats, high-net-worth individuals, and luxury waterfront property owners. Divorce and family law matters in Key Biscayne frequently involve complex international asset structures, offshore accounts, luxury real estate valuation, and timesharing arrangements with cross border considerations. Our firm has the experience to navigate these matters effectively in Miami-Dade Family Court.
Where Key Biscayne Family Law Cases Are Heard
Key Biscayne is in Miami-Dade County, so family law cases for Key Biscayne residents are filed in the Eleventh Judicial Circuit. The primary family courthouse is the Lawson E. Thomas Courthouse Center at 175 NW First Avenue, Miami, Florida 33128, which houses the family division and the domestic violence division. Petitions for dissolution of marriage, paternity actions, timesharing disputes, child support proceedings, and injunctions for protection are heard there.
Residency is a threshold requirement. Under Fla. Stat. § 61.021, at least one spouse must have resided in Florida for six months before the petition for dissolution is filed.
Divorce in Key Biscayne
Florida is a no-fault divorce state. The principal ground for dissolution of marriage is that the marriage is irretrievably broken. Fla. Stat. § 61.052. At least one spouse must have been a Florida resident for a minimum of six months before filing. Fla. Stat. § 61.021.
Divorce proceedings for Key Biscayne residents are handled by the Eleventh Judicial Circuit Family Division in Miami-Dade County. Our firm guides clients through every stage of the process, from initial filing through mediation, discovery, and trial if necessary.
Equitable Distribution in Key Biscayne Divorces
Florida divides marital assets and liabilities equitably between spouses under
Fla. Stat. § 61.075. In Key Biscayne divorces, equitable distribution frequently involves:
- Key Biscayne luxury waterfront condominiums and single-family homes
- Offshore and international accounts
- Foreign real estate and international investment portfolios
- Business ownership interests and professional practices
- Retirement accounts including 401(k), IRA, and pension plans
- Boats, vessels, and watercraft
- Cryptocurrency and digital assets
Key Biscayne divorces involving international assets frequently require coordination with foreign counsel and forensic financial analysis to ensure full disclosure and proper valuation of all marital property. Our firm has experience handling these complex cross-border asset matters.
When a Nonmarital Home Becomes Partly Marital
Key Biscayne has a high proportion of residents who owned their home or condominium before they married. It is a common assumption that a property owned before the marriage stays entirely outside the divorce. Florida law is more nuanced than that.
The enhancement rule
Under Fla. Stat. § 61.075(6)(a)1.b, marital assets include the enhancement in value and appreciation of nonmarital assets resulting from the efforts of either party during the marriage, or from the contribution to or expenditure on them of marital funds. The underlying property can remain nonmarital while a portion of its increase in value is marital and divisible.
What this looks like in practice
A spouse who owned a Key Biscayne condominium before the marriage, then used income earned during the marriage to pay down the mortgage, renovate the kitchen, or fund a special assessment, has likely created a marital interest in part of the appreciation. The same is true where a spouse’s own labor during the marriage materially improved the property.
Passive appreciation is treated differently
The statute keys on efforts and on marital funds. Appreciation that is purely passive, market movement that would have occurred whether or not either spouse lifted a finger, is not what the provision captures. Separating passive market appreciation from enhancement attributable to marital effort or money is the analytical work in these cases, and in a contested matter it usually calls for records going back to the date of marriage and, frequently, an expert.
Child Custody and Timesharing in Key Biscayne
Florida law governs parental responsibility and timesharing through a mandatory Parenting Plan. Fla. Stat. § 61.13. Effective July 1, 2023, Florida established a rebuttable presumption that equal timesharing – a 50/50 schedule – is in the best interests of the child. Fla. Stat. § 61.13(2)(c)(1).
Key Biscayne families with international ties present unique timesharing challenges – including international relocation requests, Hague Convention considerations, and passport and travel consent disputes. Our firm handles these complex cross border custody matters and represents parents in contested timesharing proceedings before Miami-Dade Family Court.
Child Support in Key Biscayne Divorce and Paternity Cases
Florida calculates child support under the income shares model in Fla. Stat. § 61.30. A statutory guidelines schedule produces a base obligation from the parents’ combined monthly net income and the number of children. That amount is apportioned between the parents in proportion to their incomes and adjusted for health insurance, uncovered medical costs, and work-related child care.
The parenting plan feeds directly into the arithmetic, because the number of overnights each parent exercises changes the calculation. That is one reason timesharing and support are negotiated together rather than settled one after the other. Where a parent’s income is not a simple salary, or where combined income exceeds the top of the schedule, the court must first determine net income before the guidelines can be applied, and any departure from the guidelines figure requires written findings.
Paternity in Key Biscayne
Where the parents were not married when the child was born, paternity has to be established before either parent can enforce anything. Under Fla. Stat. § 742.011, a proceeding to determine paternity may be brought by a woman who is pregnant or has a child, by a man who has reason to believe he is the father, or on behalf of the child.
The consequence of skipping that step is regularly misunderstood. Until a court enters an order, an unmarried father has no enforceable right to timesharing or to participate in major decisions, and the mother has no enforceable claim for support. Appearing on the birth certificate is not a judicial determination of paternity. The same proceeding can establish paternity, a parenting plan, a timesharing schedule, and a support obligation together.
Alimony in Key Biscayne Divorce Cases
Florida’s alimony law was significantly reformed effective July 1, 2023. Permanent
alimony was abolished. Courts may now award bridge-the-gap, rehabilitative, or durational alimony based on the length of the marriage and the factors set forth in
Fla. Stat. § 61.08.
Key Biscayne divorces frequently involve high-income earners and significant lifestyle considerations that factor into alimony determinations. Our firm represents both payors and recipients of alimony in negotiation and litigation throughout Miami-Dade County.
Prenuptial Agreements for Key Biscayne Residents
For international residents, high-net-worth individuals, and luxury property owners in Key Biscayne, a well-drafted prenuptial agreement is essential for protecting pre-marital assets, international holdings, and financial plans. Florida prenuptial agreements are governed by the Florida Premarital Agreement Act, Fla. Stat. § 61.079.
Our firm drafts and reviews prenuptial and postnuptial agreements for Key Biscayne residents with particular attention to international asset structures and cross-border enforceability considerations.
Frequently Asked Questions: Key Biscayne Divorce Attorney
Where is my divorce case filed if I live in Key Biscayne?
Key Biscayne is in Miami-Dade County, so the case is filed in the Eleventh Judicial Circuit. The primary family courthouse is the Lawson E. Thomas Courthouse Center at 175 NW First Avenue, Miami, Florida 33128.
How long must I live in Florida before filing for divorce?
Six months. Fla. Stat. § 61.021 requires one of the parties to have resided in Florida for six months before the petition is filed.
Is my spouse entitled to half of everything?
The starting point is close to that. Fla. Stat. § 61.075 requires the court to begin from the premise that distribution should be equal, and a court dividing marital assets unequally in a contested case must make specific written findings tied to the statutory factors.
Does Florida still award permanent alimony?
No. Fla. Stat. § 61.08 authorizes temporary, bridge-the-gap, rehabilitative, and durational alimony. Permanent alimony was eliminated, and the length of the marriage governs what is available.
How is child support calculated in Florida?
Under the income shares model in Fla. Stat. § 61.30, using the parents’ combined monthly net income, the number of children, and the number of overnights in the parenting plan, adjusted for health insurance, uncovered medical costs, and child care.
Can I move away with my child after the divorce?
Not without consent or a court order. Under Fla. Stat. § 61.13001, a change in the child’s principal residence of at least 50 miles for at least 60 consecutive days is a relocation requiring the other parent’s written agreement or court approval.
I owned my home before the marriage. Is it safe?
The property itself is generally nonmarital, but part of its increase in value may not be. Under Fla. Stat. § 61.075(6)(a)1.b, enhancement and appreciation resulting from either spouse’s efforts during the marriage, or from marital funds spent on the property, is a marital asset. Purely passive market appreciation is treated differently.
