The Short Answer
There are four ways to leave money to a grandchild, and they differ on the three questions that matter. Who holds the money while the grandchild is young, at what age the grandchild takes control, and whether anything protects the gift after that.
| The route | Who manages it | Grandchild controls at | Protection after |
|---|---|---|---|
| Named directly in a will | A court-appointed guardian, above $15,000 | 18 | None |
| Custodial account (FUTMA) | The custodian you name | 21, or 25 with a catch | None once it ends |
| 529 plan | The account owner | Education spending only | Good, for one purpose |
| Trust share | The trustee you choose | The age you choose, or never fully | Renewable for life and beyond |
The 529 is a fine education tool and works alongside everything here. For the inheritance itself, the trust is the only route where you pick the age, name the manager, and keep the protection running after the handover, and for most grandparents it costs a few paragraphs inside the revocable living trust they already need.
Why You Cannot Just Leave Money to a Minor
Florida law lets a parent receive and manage only a limited amount for their own minor child without court involvement. Under Fla. Stat. §744.301(2), the cap is $15,000 in the aggregate, whether the money comes from a settlement, an estate, or a trust. Above that, someone has to petition the court, be appointed guardian of the property, post the required filings, and account to a judge until the child turns 18, when the child takes everything outright. The guardianship spends your gift on court costs and hands the balance to an 18-year-old. Every route below exists to avoid that outcome.
What About a Custodial Account?
A Florida custodial account under the Uniform Transfers to Minors Act, ch. 710, is the simple option, and for small gifts it is often enough. An adult you name holds the account and spends for the grandchild’s benefit with no court involvement. It has two built-in limits. First, it ends. Custodial property from a lifetime gift goes to the grandchild at 21 under §710.123, and while a transferor can extend the custodianship to 25, the statute gives the grandchild a window to demand everything at 21 anyway unless a specific written notice procedure is followed on time. Second, the day it ends, the money is the grandchild’s outright, with no protection from anything that happens next. A custodial account is a container with a timer. A trust is a container with rules.
The Trust Options, from Simple to Multi-Generation
Three designs cover nearly every family, in rising order of ambition.
- Grandchildren’s provisions inside your revocable trust. This is the common one. Your trust says what happens if a share passes to a grandchild, names the trustee, sets the distribution standard for health and education along the way, and picks the age for control, commonly staged at 25 and 30. It also catches the scenario nobody plans for, where a child dies before you and that child’s share drops down a generation. The provisions cost a flat $750 add-on to our trust-based plan.
- A standalone gift trust, funded now. For grandparents who want to give during life rather than leave an inheritance later. Annual exclusion gifts of $19,000 per grandchild per giver (2026) go into the trust each year, an attorney-drafted withdrawal-notice procedure keeps them tax-free, and the money grows under your rules instead of in a custodial account with a timer. Quoted at the consult, because the design depends on the gift program.
- The bloodline design. Each grandchild’s share stays in trust for life. The grandchild takes over management of their own share as an adult, the assets stay protected from their divorces and creditors, and whatever remains passes to their children rather than to an in-law. Florida allows the structure to run up to 1,000 years under Fla. Stat. §689.225, which is the same law behind the Florida dynasty trust. Our guide to protecting your child’s inheritance walks through the case law that makes the protection real.

The numbers are friendlier than most grandparents expect. You can give each grandchild $19,000 a year (2026) with no gift tax return, and a married couple can give $38,000. Tuition paid directly to the school and medical bills paid directly to the provider do not count against that at all. Bigger transfers use your lifetime exemption of $15 million per person, so federal gift and estate tax is simply not in play for most families, and Florida has no estate or inheritance tax of its own. There is a separate federal tax on skipping a generation, aimed at very large fortunes, and it has its own $15 million exemption. For the families it does touch, the planning lives on the dynasty trust page. For everyone else the real tax planning is simpler, since inherited assets receive a stepped-up basis while gifted assets carry your old basis, which is one more reason the trust-at-death design usually beats giving appreciated assets away early.
Two Traps When You Skip a Generation
1. Share language that disinherits a branch. "To my grandchildren equally" and "to my descendants per stirpes" produce different families getting different money the moment one of your children has a different number of kids, or dies first. We draft the shares by branch, name the backup takers, and add a survivorship rule so a common accident cannot route a share through the wrong estate. It is one page of drafting that prevents the most common grandparent-gift dispute we see in litigation.
2. The trustee in the middle of a divorce. Naming your child as trustee of their kids’ shares is natural and usually right. It goes wrong when that child’s own marriage or finances are unstable, because the account statements, the discovery requests, and the pressure all arrive at their kitchen table. Your trust can name a co-trustee or an independent backup, and give a trust protector the power to make a change without going to court. If any grandchild receives disability benefits, the share belongs in a special needs trust from the start.
What This Costs
Grandchildren’s provisions ride inside a trust-based estate plan. The plan is a flat $3,200 for an individual and $4,500 for a couple, and the grandchildren’s, minors’, and spendthrift provisions are a $750 add-on, drafted to your family rather than from a form bank. A standalone lifetime gift trust or a full bloodline design is custom work quoted at the consult. Recording and other government costs are additional and passed through at cost.

Frequently Asked Questions
How Do I Set Up a Trust for My Grandchildren?
For most grandparents it is a set of provisions inside your revocable living trust rather than a separate document. Your trust names the grandchildren’s shares, the age or standard for distributions, and the trustee who manages the money until then. A standalone gift trust funded during your lifetime is the second route, used when you want to make annual gifts now rather than an inheritance later. Both are drafting projects an estate planning attorney handles inside a normal plan.
How Much Can I Give My Grandchildren Tax Free?
The federal annual exclusion is $19,000 per grandchild per giver in 2026, so a married couple can give each grandchild $38,000 a year with no gift tax return at all. Tuition paid directly to the school and medical bills paid directly to the provider are unlimited on top of that. Larger gifts simply use part of your lifetime exemption, which is $15 million per person in 2026, so almost no Florida family actually pays gift tax. Florida has no state gift, estate, or inheritance tax of its own.
At What Age Should a Grandchild Get the Money?
Later than most people first say. At 18 a custodial arrangement under the old rules would hand over everything, and Florida’s custodial accounts end at 21, or 25 with the right election. A trust lets you choose, and common designs stage distributions at 25 and 30, or keep the share in trust for life with the grandchild taking over as trustee once they are mature. The lifetime version is what keeps the money protected from a future divorce or lawsuit, which is covered in our guide to protecting an inheritance.
What Is a Bloodline Trust?
A trust designed so the money follows your family line. Each child or grandchild benefits from their share for life, and whatever remains passes to their own children rather than to a spouse or an ex-spouse. Florida law supports the design well, since a trust here can run up to 1,000 years and the creditor protection renews at each generation. It is the same architecture as a dynasty trust, scaled to an ordinary family.
Can My Grandchild’s Parent Manage the Money?
Yes, and it is often the right choice. Your trust can name your adult child as trustee of their own children’s shares, with the checkbook and the investment duties, subject to the distribution rules you wrote. Think about family facts first. A child in a rocky marriage, with creditor trouble, or with poor money habits argues for a different trustee or a co-trustee, and your trust can name a backup and let a trust protector make a change later.
What If My Grandchild Receives Disability Benefits?
Never leave the money outright. An inheritance in the grandchild’s own name counts against the $2,000 resource limit for SSI and Medicaid and can end their benefits the month it arrives. The share goes into a third party special needs trust instead, which supplements benefits without disqualifying them, and there is no payback to the state because it was never the grandchild’s money. We build that as part of the same plan.
Common Situations
The grandparents with a 529 already. College is funded, and they want to leave $60,000 more to each of five grandkids. We added grandchildren’s provisions to their trust, with distributions staged at 25 and 30 and each parent serving as trustee for their own kids. Total drafting cost was the $750 add-on.
The share that skipped down. A widow’s son passed away before her, and his third of her estate now belongs to his two young children. Because her trust already held grandchildren’s provisions, the shares stayed in trust with her daughter-in-law as trustee instead of landing in a court guardianship that would have paid out at 18.
The family that wanted the money to stay in the family. Grandparents with a seven-figure estate wanted their wealth protected through their children’s marriages and on to the grandchildren. We built lifetime shares with the bloodline remainder, each adult child managing their own share, and an independent trustee ready if trouble ever appears.
