Last (Wo)Man Standing: Why Blended Families Need Estate Plans the Most

If you have a spouse and children from a previous relationship, you want two things: to take care of your spouse, and to make sure your kids receive what you intended for them. Those goals can work against each other, and Florida law doesn’t always settle the tension the way you’d expect.

At Aventus Law Group, we help blended families in Winter Park, Orlando, and across Florida put plans in place that reflect what they actually want. Here’s what to know before you start.

What Happens Without a Will in Florida

If you pass away without a valid will, Florida’s intestacy laws decide who gets your probate assets. When you leave a spouse and children who are not also your spouse’s children, your spouse generally receives half of the estate. Your children share the other half. That split may not match what you had in mind.

Stepchildren are in a tougher spot. Unless you legally adopted them or named them in your estate plan, they generally have no inheritance rights under Florida law.

Why Having a Will Isn’t Always Enough

Many people assume a will lets them leave their assets to anyone they choose. In Florida, a surviving spouse has legal rights that can override a will.

A surviving spouse can generally claim 30% of the deceased spouse’s “elective estate,” even if the will leaves everything to children from a prior marriage. The elective estate can include some assets that never go through probate, such as property held in a revocable trust. So your children may end up with less than you planned.

A Quick Example

Here’s a simplified, hypothetical case. Say you remarry and have about $1 million in assets. Your will leaves everything to your two children from your first marriage. Your spouse can still claim 30% of the elective estate, roughly $300,000 here, and may also have homestead rights in the house. Your children receive less than you planned, even though nobody did anything wrong.

The Family Home Can Be a Sticking Point

Florida’s homestead rules add another layer. When a married homeowner dies, there are limits on leaving the home directly to children if a spouse survives. Often, the spouse can live in the home for life, and the children receive what’s left after that.

That arrangement can work, but it can also cause friction if the spouse and the children disagree about what should happen to the house. In some cases, a spouse can waive certain rights through a valid written agreement.

Common Estate Planning Mistakes in Blended Families

Even people who already have documents can run into trouble. These are the problems we see most:

• Leaving everything to your spouse and trusting they’ll pass it to your children later. Once the assets are theirs, you have no say in where they go.
• Mismatched beneficiary designations. Retirement accounts and life insurance go to the person named on the form, no matter what your will says.
• No plan for the family home after one spouse dies.
• Picking a trustee or personal representative who is caught in the middle, such as a spouse or child who may struggle to stay neutral.
• Not updating documents after a marriage, a new baby, or the sale of a business.

Planning Options That Can Help

The right setup depends on your assets, your family, and your goals. Some common tools include:

• Premarital or postnuptial agreements to spell out each spouse’s expectations and address certain inheritance rights.
• Trusts that let your spouse use property or receive income during their lifetime, with what remains passing to your children afterward. A QTIP trust is a common version of this: your spouse receives the income for life, and your spouse can’t redirect what’s left to someone else.
• An independent trustee to make decisions according to the trust’s terms and keep family tension down.
• Life insurance, separate accounts, and careful asset ownership to give your children a more predictable inheritance while your spouse stays financially secure.

The key is making sure everything works together. Your will, trusts, beneficiary forms, deeds, and business agreements should all point the same direction.

Guardianship and Incapacity Planning

Estate planning isn’t only about what happens after you die. If you have minor children, a stepparent generally has no automatic legal authority over a stepchild without an adoption or a court order, so it’s important to put your wishes in writing.

A durable power of attorney and a health care surrogate designation matter too. They name who can handle your finances and medical decisions if you become incapacitated.

If You Own a Business

Your business may be your largest asset, and a blended family makes it harder to sort out. Will your spouse take it over, your children, or will it be sold? If your spouse inherits it, your children may have no say. If your children inherit it, your spouse may depend on the income it provides.

A buy-sell agreement and a succession plan can answer those questions ahead of time, as long as they match your will and trust. If you’re thinking about selling in the next few years, it’s worth planning before the sale, not after.

Frequently Asked Questions

Do stepchildren inherit in Florida?

Not automatically. Unless you adopt them or include them in your will or trust, stepchildren generally don’t inherit under Florida’s intestacy laws.

Can my spouse give up their right to part of my estate?

In some cases, yes, through a valid written agreement. The details matter, so it’s best to have an attorney draft it.

If I put my assets in a revocable trust, can my spouse still claim a share?

Possibly. Revocable trust assets can be included in the elective estate, which is what the 30% claim is based on.

Start a Plan That Protects Your Family

The goal is simple: your spouse is provided for, your children are protected, and nobody has to guess what you wanted.
