How Do I Leave Assets to Minor Children?

Leaving money or property to a young child sounds simple until you realize that the law will not let a minor take control of significant assets on their own. How you structure the gift determines whether your child is protected or left with a legal tangle at the worst possible moment.

Why You Cannot Just Leave Assets to a Minor Outright

A minor cannot legally manage or hold title to substantial property. If your will or beneficiary designation simply hands assets directly to a child who is under eighteen, the money cannot just be deposited into the child's hands. Instead, a court typically has to get involved to appoint someone to manage the funds until the child reaches adulthood, and that oversight continues under the court's supervision. That process costs money, takes time, and often ends with the child receiving everything in a lump sum at eighteen, an age at which many young adults are not equipped to handle a large inheritance wisely.

The good news is that Washington law gives you several better ways to provide for a minor. Each has its place, and the right choice depends on how much is involved and how much control you want to keep over when and how the child receives it.

A Testamentary Trust Built Into Your Will

One of the most flexible options is a testamentary trust, which is a trust created inside your will that comes into being when you die. You name a trustee to hold and manage the assets for your child, and you write the rules: at what ages the child receives distributions, what the money can be used for along the way, such as health, education, and living expenses, and when the trust finally ends. Washington's trust law, found in chapter 11.98 RCW, governs how that trustee must operate, including the duty to manage the property prudently and to administer the trust for the benefit of the child.

The great advantage of a testamentary trust is control over timing. Rather than a lump sum at eighteen, you might direct that your child receive part of the trust at twenty-five, part at thirty, and the balance at thirty-five, with the trustee free to spend on the child's needs in the meantime. For families with meaningful assets, or for a child who may need extra structure, this tends to be the most protective option.

A Custodianship Under Washington's Uniform Transfers to Minors Act

For more modest amounts, a simpler tool often does the job. Washington has adopted the Uniform Transfers to Minors Act, found in chapter 11.114 RCW. It lets you leave property to a custodian who holds and manages it for the child until a set age, without the expense of drafting a full trust.

A custodian under this act has real responsibilities. Under RCW 11.114.120, the custodian must keep records of all transactions and manage the property with the standard of care that applies to fiduciaries. The tradeoff for its simplicity is less flexibility on timing. Under RCW 11.114.200, custodial property generally must be turned over to the child at twenty-one for property transferred by will or trust, and at eighteen in certain other situations. You do not get to fine-tune the ages the way a trust allows, but for smaller gifts the ease and low cost are often worth it.

A Guardianship of the Estate

If assets pass to a minor without a trust or a custodianship in place, a court may need to establish a guardianship of the estate, sometimes called a conservatorship of the child's property. A guardian of the estate is appointed and supervised by the court to manage the child's property until adulthood. This is the default that kicks in when no better plan exists, and it is generally the least attractive of the three. It involves ongoing court oversight, reporting requirements, and cost, and like an outright gift it usually ends in a full handover when the child turns eighteen. Setting up a trust or a custodianship in advance is almost always preferable to leaving your family to the guardianship process.

Do Not Overlook Beneficiary Designations

One of the most common and avoidable mistakes is naming a minor child directly as the beneficiary of a life insurance policy or a retirement account. Those designations pass outside your will, so even a carefully drafted testamentary trust will not catch them unless you coordinate. If a minor is named directly, the same problems return: a court may have to step in to manage the money. The fix is to name a trust or a custodianship as the beneficiary instead, or to otherwise coordinate those accounts with the rest of your plan. Reviewing your beneficiary forms is just as important as writing your will.

A Note for Married Parents in Snohomish County

Married couples in Washington should also keep community property rules in mind. Under RCW 26.16.030, neither spouse may give away more than one-half of the community property by will. That rule affects how much either parent can direct into a trust or custodianship for the children, and it is one more reason to build the plan with care rather than assumption.

Protect Your Children With a Plan That Fits

Providing for a minor child is one of the most important reasons to have an estate plan at all, and it is one of the easiest to get wrong with a form or a guess.
