Understand Florida Income Shares & 2023 Alimony Reform

Q: What changed in Florida’s 2023 alimony reform?

Permanent alimony was eliminated. Durational alimony now has strict duration caps based on marriage length and a 35% income differential cap. Rehabilitative support is capped at five years and bridge-the-gap remains limited to two years.

Q: How does Florida’s Gross Up child support method work?

When both parents have substantial time-sharing (73+ overnights each), the combined obligation is multiplied by 1.5 and costs are cross-credited to reflect dual households, per Florida Statute § 61.30(11)(b).

Q: What is the health insurance reasonable cost rule in Florida?

Health insurance premiums are presumed reasonable if they do not exceed 5% of the providing parent’s gross income. Courts may adjust support if costs surpass that threshold.

Q: Can alimony be modified after the 2023 reform?

Durational alimony amounts remain modifiable upon a substantial change in circumstances, but duration can only change in exceptional cases. All support terminates automatically at death and generally at recipient remarriage or supportive relationship.

Income Shares + Gross Up

Florida Statute § 61.30 framework

Florida’s support begins with combined monthly gross income, referencing the guideline schedule to establish the basic obligation. When substantial time-sharing occurs, the Gross Up method multiplies obligations by 1.5 and cross-credits expenses to reflect two households.

Reasonable cost tests keep insurance affordable—health premiums must be ≤5% of gross income. Uninsured medical costs are typically split proportionally or as the court orders.

2023 Alimony Durational Rules

Permanent alimony eliminated, caps enforced

Durational alimony now carries strict limits: 50% of marriage length for short-term (<10 years), 60% for moderate (10-20 years), and 75% for long-term (20+ years). Amounts cannot exceed 35% of the net income difference.

Rehabilitative support requires a defined plan and is capped at five years. Bridge-the-gap remains two years. Cohabitation and remarriage terminate support automatically, in addition to death of either party.
