Leaving Money to Adult Children: Outright, in Trust, or Something Between

Most parents' estate plans leave everything to the children, equally, outright, at the second death. For many families that's exactly right. For families with more than a couple of million dollars, or with a child whose marriage, career, or judgment carries some risk, whether to leave the inheritance in trust deserves a real answer. And the trust designs available now are far more flexible than the ones parents remember from their own parents' plans.

Outright

An outright bequest is simple and cheap. The child receives the assets, owns them, and does whatever they want. No trustee, no separate tax return, no ongoing administration. The inherited assets get a step-up in basis, and inherited retirement accounts pass under the 10-year rule straight to the child.

The cost is exposure. Assets the child owns outright are reachable by the child's creditors, in a lawsuit, and, depending on how the child handles them, in a divorce. An inheritance kept in a separate account is generally separate property in Florida and most states. An inheritance that gets commingled with marital funds, used to buy a jointly titled house, or dropped into a joint account can become marital property. Many adult children commingle within a year. We've watched it happen over and over. The assets also sit fully in the child's taxable estate at their own death.

In trust

A trust for an adult child holds the inheritance under a trustee's management, distributes according to the document's terms, and keeps the assets legally separate from the child. A well-drafted discretionary trust with a spendthrift clause protects the assets from the child's creditors, from a divorcing spouse (the trust assets aren't the child's property and, if distributions haven't been commingled, aren't marital), and from the child's own worst decisions. It can also be built to skip the child's estate for estate tax purposes and pass to grandchildren, using the parents' GST exemption.

The costs are real, though. Legal fees to draft it. A trustee to run it. An annual trust tax return. Compressed trust tax brackets on income that's retained (the top 37% rate kicks in above about $16,000 of trust income in 2026, which pushes trustees to distribute income). And the child's potential resentment at being "not trusted," which is the one parents underestimate.

The middle designs

The choice isn't outright versus a restrictive trust. The designs that most often fit capable adult children keep the protection and hand the child the control.

The child as trustee. A discretionary trust where the child serves as their own trustee (or co-trustee with an independent party) and can distribute to themselves for health, education, maintenance, and support. The child manages the investments, decides on distributions within the standard, and lives with the money much as they would outright. Because the assets are held in trust under an ascertainable standard, they stay protected from the child's creditors and divorcing spouse under most states' law, including Florida's. The child can also be given the power to appoint an independent trustee for purely discretionary distributions beyond the standard.

The beneficiary-controlled trust with a removal power. The child can't be trustee but can remove and replace the trustee at will. Practical control without legal ownership.

A lifetime trust that converts. The trust can give the child the right to withdraw the assets at a chosen age, or leave them in trust at the child's election. A child who wants simplicity takes the money; one who values protection keeps it where it is.

Staggered distributions, one-third at 25, 30, and 35, are the traditional design and the least useful one for adult children. By 35 the protection is gone, the child has had three separate chances to receive a lump sum at a moment of uncertainty, and the trust has cost money for nothing. Staggered distributions make some sense for young beneficiaries. They make very little sense for a child who's already 45.

Retirement accounts

An IRA left to a trust is a special case. Under the 10-year rule, an IRA inherited by a trust still has to be emptied within ten years, and if the trust holds onto the distributions rather than passing them to the child, the income gets taxed at trust rates. A conduit trust passes the distributions through to the child (protection ends for whatever's distributed); an accumulation trust keeps them (protection continues, tax is higher). For most families the answer is to leave the IRA outright or through a conduit trust, and to put taxable and Roth assets, which have no forced distribution schedule, in the protective trust. The beneficiary designations have to match the plan, or none of this works.

Deciding

The questions we walk through with parents:

• How much will each child receive, and is it enough to change their life or their exposure?
• Is the child's marriage stable, and does the spouse's family have a history of litigation or financial trouble?
• Is the child in a profession with liability exposure (medicine, business ownership, real estate)?
• Has the child managed money well so far?
• Does the child have a child with special needs, an addiction, or another circumstance a trust would protect against?
• Will the family's estate exceed the exemption in the child's generation, so that generation-skipping design has tax value?
• Does the parent want to shape what the money is for (education for grandchildren, a home, a business), or just protect it?

A capable child, a stable marriage, a $500,000 inheritance: outright. A capable child, a stable marriage, $5 million: a beneficiary-controlled trust, for the protection alone. A child with any of the risk factors above: a trust with an independent trustee for at least part of it.

Tell them

Whatever the design, the child should hear about it before the parent dies. An adult child who learns at the funeral that their inheritance is in trust hears "not trusted." One who heard, years earlier, that the trust was there to protect against divorce and lawsuits and that they'd control it hears something else entirely. The family meeting is part of the plan, not an optional extra.

Where we come in

The design is part of the estate plan, decided with the parents and drafted by their attorney. We model what each child will receive, the tax effect of trust versus outright treatment on retirement accounts and taxable assets, and the practical administration the child will actually face. Then we make sure the beneficiary designations and the titling deliver the assets the way the documents intend. That last step is where most plans quietly fail.
