Blended families are the norm across Miami, and they raise a hard question: how do you provide for a current spouse while protecting children from a prior relationship? Florida law adds specific guardrails, and the planning tool you choose largely determines whether your wishes hold. Here is a comparison of the main approaches.
The Florida Rules You Cannot Ignore
Two provisions shape every blended-family plan. First, the elective share (Fla. Stat. §732.2065 and following) gives a surviving spouse the right to 30% of the elective estate, regardless of what your will says. Second, homestead under Art. X, §4 of the Florida Constitution restricts how you leave your primary residence: if you have a spouse or minor child, you generally cannot devise the homestead freely. A surviving spouse typically receives a life estate (or can elect a half interest), with the remainder to your descendants. These rules can unintentionally pit a spouse against children if you plan around them carelessly.
Option 1: A Simple Will
A will under §732.502 is better than nothing, but for blended families it is the weakest tool. If you leave everything to your spouse outright, nothing legally compels that spouse to pass assets to your children later. And the will still runs through Miami-Dade probate, where homestead and elective-share disputes commonly surface.
Option 2: A Revocable Trust
A revocable trust under Chapter 736 gives far more control. You can provide your spouse income and the right to live in a home for life, then direct the remainder to your children. This is the classic structure for second marriages, often built as a marital or QTIP-style trust. Assets in the trust avoid probate, stay private, and the successor trustee enforces your two-tier plan without relying on goodwill between step-relatives.
Option 3: A Marital Agreement Plus a Trust
Spouses can waive or modify elective-share and homestead rights through a valid prenuptial or postnuptial agreement under Florida law. Paired with a trust, this lets a couple agree in advance how assets divide, removing the surprise that often fuels litigation after a death in Miami families.
Beneficiary Designations: The Quiet Risk
Life insurance, IRAs, and POD accounts pass by designation, not by your will or trust. In blended families, an outdated form naming an ex-spouse or only one set of children is a common and painful mistake. These should be reviewed alongside the rest of the plan.
Which Approach Fits?
If your goal is simply to leave everything to your spouse, a will may suffice, but it offers no protection for your children. If you want to care for your spouse and guarantee something for your children, a revocable trust, often combined with a marital agreement, is the stronger choice. The right structure depends on the home, the ages of any minor children, and the relationships involved.
