When you sit down to plan what you’ll leave your children, you’re really trying to answer one question: how do I make sure this actually helps them?
Two tools come up a lot in that conversation – the dynasty trust and the special needs trust. They sound like they might be competitors, or two versions of the same idea. They’re not. Both protect your child’s inheritance, but they protect it from completely different things. And choosing between them isn’t about which one is “better.” It’s about who your child is, what their needs are, and what you’re protecting them from.
Let us walk you through the difference, because once you see it, the right choice usually becomes clear.
What the Two Trusts Have in Common
Let’s start with why people confuse them in the first place, because there is some “overlap”.
Both are ways of leaving money to your child without simply handing it to them outright. Both can keep that money out of the reach of a divorcing spouse or a creditor. And both are built on the same basic insight: sometimes the most loving thing you can do isn’t to give someone a pile of cash, but to set up a structure that supports and protects them over time.
So if you’ve been told “you need a trust for your child,” and you’re trying to figure out which kind, you’re asking the right question. The answer comes down to one more: does your child rely on, or might they ever rely on, needs-based public benefits?
It might not be the first question that comes to mind, but it’s an important one.
What Is a Dynasty Trust?
A dynasty trust is an irrevocable trust designed to protect and pass down wealth across more than one generation: your children, then your grandchildren, and sometimes beyond. (I’ve written a full explainer on how dynasty trusts work in California if you want to go deeper.)
Here’s what it’s really for. Money placed in a dynasty trust isn’t legally your child’s money, even though they can benefit from it. That’s what gives it its power:
- If your child ever goes through a divorce, what’s in the trust stays with your child – it doesn’t walk out the door with an ex-spouse.
- If your child is ever sued, or works in a profession where lawsuits are a real risk, the trust assets are generally protected.
- And for families with larger estates, a dynasty trust can pass wealth to future generations in a tax-efficient way.
In California, a dynasty trust can last up to about 90 years, thanks to our state’s rule against perpetuities – usually, about three generations of protection before the trust distributes what’s left.
What a dynasty trust does not do is protect your child’s eligibility for needs-based public benefits. And for some families, that’s the one thing that matters most.
What Is a Special Needs Trust?
A special needs trust (SNT) is also sometimes called a supplemental needs trust; they’re two names for the same thing. It is built for a specific and very important job: it lets you leave money for your child with a disability without disqualifying them from the public benefits that support their care. (You can read more about how we approach special needs trusts here.)
Here’s why that matters. Programs like Supplemental Security Income (SSI) and Medi-Cal are needs-based, which means they come with strict asset limits. SSI’s limit is just $2,000. And in 2026, California reinstated a Medi-Cal asset limit – $130,000 for an individual – for the disability and aged programs many of our families rely on. (In 2027, that limit may change again.) For a person with a disability, Medi-Cal is often the doorway to far more than health coverage: it provides in-home support, therapies, and other services your child may depend on every day.
Now here’s the trap. If you leave your child an inheritance outright – even a modest one – you can push them over those limits and cost them the very benefits that fund their care. Families don’t do this on purpose. They do it out of love, not realizing the gift can do harm.
A special needs trust solves this problem. Assets held in a properly drafted third-party SNT don’t count against those limits, because your child doesn’t own or control them. The trust can pay for the things that make life fuller – travel, hobbies, education, a caregiver, the extras that benefits don’t cover – while the benefits keep doing their part. It’s not an either/or, it’s both.
One important note about how these are structured, because it’s a common point of confusion. A third-party special needs trust – the kind that holds what you leave, not assets already in your child’s name – is connected to the rest of your estate plan. It receives what you’re passing on through your revocable living trust and your beneficiary designations. It isn’t something you fund during your lifetime, and it shouldn’t be buried inside your revocable trust. Getting that coordination right is a big part of what we do.
(There’s also a first-party special needs trust, used when the money is already in your child’s name – say, from a settlement or an inheritance they received directly. That version carries a Medi-Cal payback requirement. It’s a different tool for a different situation, but it’s worth knowing it exists.)
The Real Difference: What Are You Protecting Against?
Here’s how I describe it to a family sitting across from me.
A dynasty trust protects your child’s inheritance from outside threats like divorce, creditors, lawsuits, and estate taxes across generations.
A special needs trust protects your child’s inheritance from a threat most people never see coming: the risk that the inheritance itself disqualifies them from the benefits that fund their daily care.
Same goal – to protect what you leave your child – but completely different dangers.
And notice something: a well-drafted third-party special needs trust already gives you much of what a dynasty trust gives you. Because your child doesn’t own or control the assets, they’re generally shielded from your child’s divorce and creditors, too. So for a family whose child relies on public benefits, the special needs trust usually isn’t a step down from a dynasty trust – it does the protective work and the benefits work at the same time.
When a Dynasty Trust Is the Right Tool
A dynasty trust tends to be the right fit when:
- Your child does not rely on needs-based public benefits, and isn’t likely to.
- You want to protect their inheritance from divorce, lawsuits, or creditors.
- You have a larger estate and want to pass wealth to grandchildren and beyond in a tax-efficient way.
- You want the money to stay protected and guided over time, rather than handed over all at once.
If that sounds like your family, the dynasty trust is a powerful tool – and one a lot of families don’t even realize is available to them.
When a Special Needs Trust Is the Right Tool
A special needs trust is the right tool when:
- Your child has a disability and receives (or may someday receive) SSI, Medi-Cal, or other needs-based benefits.
- You want them to be able to inherit without losing access to those programs.
- You want the inheritance to pay for the extras that make life richer, on top of what benefits provide.
- You want that money protected from your child’s own potential creditors or a divorce, too.
If your child relies on public benefits, a special needs trust is often the right tool. And this is why working with a firm that specializes in this field matters. A special needs trust that isn’t drafted correctly, or isn’t coordinated with the rest of your plan, can fall short right when your family is counting on it.
What If You’re Not Sure – or You Want Both?
Plenty of families don’t fit neatly into one box. You might have one child with a disability and another without. You might not know yet whether your child will need benefits down the road. You might want both multi-generational protection and benefits protection.
The good news: you don’t have to choose in a vacuum, and you’re not locked into a single tool for your whole family. A thoughtful estate plan can hold a special needs trust for one child and a different structure for another. What matters is that each piece is drafted for the specific child it’s protecting – and that the pieces are coordinated so they actually work together when the time comes. That coordination is the part families most often underestimate, and it’s a cornerstone of how we think about protective planning.
