“Trust” gets used as if it’s one thing, but it isn’t. The right structure depends entirely on what you’re actually trying to accomplish: control during your lifetime, protection for a vulnerable beneficiary, minimizing taxes across generations, or simply avoiding probate. Here’s a plain-language walkthrough of the trust types that come up most often in family wealth planning, and what each one is actually built to do.
Revocable living trust
The most common starting point for many families. You create it, you fund it, and you can change or dissolve it entirely during your lifetime, hence “revocable.” Its main practical benefit is avoiding probate: assets held in the trust pass to beneficiaries directly, without going through the court process a will alone requires. What it does not do is protect assets from creditors or reduce estate taxes, since you retain full control over it. It typically becomes irrevocable automatically upon your death.
Irrevocable trust
The tradeoff for giving up control. Once established, an irrevocable trust generally can’t be easily altered, amended, or revoked. In exchange, assets placed in it are usually removed from your taxable estate and gain real protection from creditors, since you no longer legally own them. This is the structural foundation many of the more specialized trust types below are actually built on.
Testamentary trust
Created through instructions in a will rather than during your lifetime. It doesn’t exist, and doesn’t hold any assets, until after death, and the estate must still go through probate first before the trust is funded. A common use case: providing for minor children without handing them a lump sum at 18.
Special needs (supplemental needs) trust
Built to provide additional support for a beneficiary with a disability, without jeopardizing their eligibility for means-tested government benefits like SSI or Medicaid. Direct inheritances can disqualify a beneficiary from those programs; a properly structured special needs trust is specifically designed to supplement, not replace, that support.
Generation-skipping trust
Designed to pass assets to grandchildren or later generations, intentionally bypassing your own children as direct recipients. The purpose is usually to avoid the estate tax being applied twice: once when assets pass to your children’s generation, and again when they eventually pass to grandchildren. Under federal tax rules, a “skip person” is generally defined as a beneficiary at least two generations younger than the grantor, or simply someone at least 37.5 years younger, regardless of actual family relationship. ACTEC, the national association of trust and estate attorneys, is a good starting point for a deeper, nonpartisan look at how these are structured.
Spendthrift trust
Built around a specific concern: protecting a beneficiary’s inheritance from their own potential poor decisions, or from creditors and claims against them. Rather than distributing a lump sum, a trustee controls the pace and structure of distributions according to the trust’s terms, which limits a beneficiary’s ability to assign away or lose the assets outright.
Marital trust (including QTIP trusts)
Common in second marriages or blended families. A marital trust provides income and support for a surviving spouse during their lifetime, while allowing the original grantor to control where the remaining principal ultimately goes after the surviving spouse’s death, often to children from a prior relationship. This balances providing for a spouse against a grantor’s wishes for their own children’s eventual inheritance.
Charitable trusts
Structured to combine philanthropic intent with tax and income planning. Broadly, these split into two directions: a charitable remainder trust pays income to you or your named beneficiaries for a period of time, with the remainder eventually going to charity, while a charitable lead trust does the reverse, paying income to charity first, with the remainder eventually passing to your beneficiaries.
Dynasty trust
An extension of the generation-skipping concept, structured to last across multiple generations rather than a single transfer. Depending on the state in which it’s established, a dynasty trust can potentially continue for a very long period, keeping assets outside the taxable estate of each successive generation as they pass through it.
Why the trust type isn’t the whole picture
Choosing the right structure is a legal decision, made with an estate planning attorney, based on your specific family situation and goals. But once a trust exists, someone still has to actually manage what’s inside it, in a way that’s fair to every beneficiary the trust is meant to serve. That’s a separate, ongoing responsibility governed by the Uniform Prudent Investor Act: balancing the interests of a current income beneficiary against a future remainder beneficiary, documenting the reasoning behind investment decisions, and coordinating closely with the attorney who drafted the trust in the first place.
That distinction, between drafting the trust and managing what’s inside it, is where our trust account portfolio management work actually lives.
