The portion the surviving spouse can claim depends on the circumstances.

The Florida Second Marriage Trap

Your second marriage is full of promise, love, and maybe even blended families. But if you have children from a prior relationship, it can also be a minefield of unintended consequences. Estate planning in a Florida second marriage isn't just a checkbox; it's a chessboard. Every piece matters. Every move counts. And if you’re not planning strategically, your children’s inheritance could be the casualty.

Let’s be blunt: love might be blind, but Florida law is not. Without proper planning, your new spouse could legally end up with assets you meant for your children. At Welch Law, PLLC in Jupiter, we see this story play out all too often. But with sharp tools, clear thinking, and a bit of Don Draper-esque strategy, you can write your own ending.

The Big Mistake: Assuming a Revocable Trust Is Bulletproof

The average Floridian thinks a revocable trust is the magic bullet. Set it up, name your kids as beneficiaries, and voilà—problem solved, right?

Not quite.

Here’s the kicker: revocable trusts are not protected from Florida’s elective share law unless they're designed and funded properly.

Under Florida Statute §732.201, a surviving spouse is entitled to an elective share of the estate—30% of the elective estate, which can include more than just probate assets. Yes, even your revocable trust may be fair game.

Real Florida Example:

After remarrying, John left everything to his children in a revocable trust. He didn’t realize that Florida law allowed his surviving spouse to claim 30% of the elective estate. The result? A courtroom battle, drained trust assets, and estranged children.

Don’t be John.

What Is the Elective Share?

Think of it as Florida's safety net for surviving spouses. The elective share exists to prevent spouses from being completely disinherited. It guarantees a surviving spouse a stake in the deceased spouse's estate—even if the will or trust says otherwise.

Assets that count toward Florida's elective estate:

  • Property in the decedent’s name alone
  • Revocable trust assets
  • Certain jointly owned property
  • Pay-on-death (POD) and transfer-on-death (TOD) accounts
  • Life insurance payable to the estate
  • Certain retirement benefits

What Happens to Your Kids’ Inheritance?

Without planning, the math can get ugly. Your kids may receive significantly less than you intended.

Even if your trust names your children as beneficiaries, your surviving spouse can assert their statutory rights. If that trust is revocable and improperly funded or structured, the assets may be up for grabs. Your legacy could be split with someone you never intended.

How to Fortify the Fortress

1. Use an Irrevocable Trust

Once assets are placed in an irrevocable trust, they are generally no longer counted in the elective estate. But there’s a catch: you give up control. This is a sophisticated move that must be executed precisely.

2. Consider a Qualified Terminable Interest Property (QTIP) Trust

A QTIP trust allows your surviving spouse to benefit from the trust during their lifetime, but ensures that the remainder passes to your children. It strikes a balance between spousal support and protecting children’s inheritance.

3. Prenuptial or Postnuptial Agreements

In Florida, these are powerful tools. A prenup can waive a spouse’s elective share and clarify exactly what happens to your assets. It’s not just for the ultra-rich. If you have kids, it's a necessity.

4. Fully Fund Your Revocable Trust

An empty or half-filled trust is an easy target. If assets are still titled in your name, they’ll be subject to probate and possibly included in the elective estate. The fix? Retitle assets now.

5. Retirement Accounts: Handle with Care

Under federal law, spouses are usually the default beneficiaries of 401(k)s and similar plans. Your spouse must affirmatively waive their rights in writing. If they don’t, your kids don’t stand a chance.

6. Update Beneficiaries and Designations

We see it all the time: clients forget to update beneficiary designations on life insurance or IRAs. Outdated forms can wreck a well-drafted estate plan. Fix it before it's too late.

7. Consider Separate Property Trusts

When each spouse contributes their own assets to separate trusts, it creates clear lines between "yours," "mine," and "ours."

Real Florida Example: The Jupiter Business Owner

A successful dentist with two children remarries lat in life. He had up a revocable trust and named his children as beneficiaries. Upon his death, his new wife claimed her elective share. Because the trust was revocable and held most of the estate’s assets, she received 30% of its value. The kids inherited the rest—but only after legal wrangling.

Had the dentist established a prenuptial agreement and used a QTIP trust, he could have provided for both his wife and children on his terms.

What Can Go Wrong (and Often Does)

  • Trust is never funded
  • No waiver of elective share in prenup
  • Spouse named on outdated IRA or life insurance
  • Children left with just the house—and a tax bill
  • Legal costs eat into trust assets
