2026 Special Needs Estate Plan: Expert Guide

Short answer: If your family includes someone with a disability who receives, or may someday need, Medi-Cal or Supplemental Security Income, do not leave that person money outright and do not name them as an equal beneficiary of your trust. A direct inheritance can knock them off benefits they depend on. The standard fix is a special needs trust that holds the money for that person without counting as their own asset, combined with a clear plan for who steps in to help with decisions once you are no longer able to.

What is a special needs trust and why would my family need one?

A special needs trust is a trust written specifically to hold assets for a person with a disability without those assets being counted against them for Medi-Cal or SSI eligibility. The trustee, not the beneficiary, controls the money. The trustee pays for things that improve the beneficiary’s life such as therapies, equipment, education, transportation, and personal care, while the beneficiary keeps the government benefits that cover basic medical care and income support.

Without this kind of trust, a well meaning inheritance can do real harm. A parent who leaves a share of the estate directly to a disabled adult child, or a grandparent who names that grandchild in a will, can accidentally push that person over the asset limit for Medi-Cal or SSI and cause benefits to be suspended until the money is spent down.

First party or third party: which trust do we actually need?

The distinction matters and families often get it backward. A first party special needs trust is funded with the beneficiary’s own money, most often an inheritance received before anyone thought to protect it, or a personal injury settlement. Because the money technically belonged to the beneficiary, this type of trust generally must reimburse Medi-Cal for benefits paid during the beneficiary’s lifetime before anything left over goes to other heirs.

A third party special needs trust is funded by someone other than the beneficiary, typically a parent or grandparent planning ahead. Because the money never belonged to the beneficiary, there is no Medi-Cal payback obligation, and whatever remains at the beneficiary’s death can pass to siblings or other family exactly as the trust document directs. If you are a parent or grandparent doing this kind of planning, a third party trust built into your own estate plan is almost always the better tool than hoping a first party trust gets set up correctly after the fact.

A pooled trust, managed by a nonprofit organization that combines the funds of many beneficiaries for investment while keeping separate accounting for each person, is a third option worth knowing about, particularly for smaller inheritances or for families who do not have someone they trust to serve as an individual trustee.

Do we need a guardian, a conservator, or both?

In California, the terms are not interchangeable and mixing them up leads to real confusion. A guardianship applies to a minor child. A conservatorship applies to an adult who cannot manage their own person, their own finances, or both. Parents of a special needs child have automatic legal authority to make decisions while the child is a minor. Once that child reaches adulthood, that authority does not automatically continue, disability or not, and the family typically needs to petition the court for a conservatorship if the adult child cannot safely manage decisions independently.

Conservatorship of the person covers decisions about health care, living arrangements, and daily welfare. Conservatorship of the estate covers financial decisions and asset management. The same person can hold both roles, or a family can split them between two people, such as one parent handling care decisions and a sibling or professional fiduciary handling money. Because conservatorship is a court process with ongoing court supervision, some families structure a special needs trust with a corporate or professional trustee specifically to reduce how much financial oversight falls to an individual conservator.

Where do ABLE accounts fit into the plan?

An ABLE account is a tax advantaged savings account available to eligible people with disabilities, and it works alongside a special needs trust rather than replacing it. Funds in an ABLE account can be used directly by the account owner for disability related expenses such as housing, transportation, education, and health care, without the account being counted against Medi-Cal or SSI eligibility the way an ordinary bank account would be.

The tradeoff is capacity. An ABLE account is meant for modest, ongoing savings and day to day flexibility. A special needs trust is built to hold a larger inheritance, a settlement, or life insurance proceeds over the beneficiary’s lifetime. Most families who need both use the special needs trust as the primary vehicle and let the trustee fund the ABLE account periodically for money the beneficiary should be able to spend without asking permission.

What makes a good trustee for a special needs trust?

The trustee has to understand both trust administration and the rules that govern the beneficiary’s public benefits, because a distribution that looks generous on paper can still disqualify the beneficiary if it is paid the wrong way. Look for someone who can commit to learning the beneficiary’s actual needs, who will keep records and file the accountings a trustee is required to provide, and who can say no to a distribution that would put benefits at risk even when a family member is pushing for it.

Some families name a parent, sibling, or trusted friend who already knows the beneficiary well. Others use a professional fiduciary or a corporate trustee for the impartiality and administrative consistency that role requires, sometimes paired with a family member serving as a trust protector or care advocate who has no financial authority but can flag when something is not working. Either structure can work. What matters is naming successor trustees several layers deep, since a special needs trust often has to run for decades.

What to do next

Pull together what you already have: any existing will or trust, information about the benefits your family member currently receives or is likely to need, and a rough list of who you would trust to serve as trustee and, separately, as conservator if it comes to that. Bring that to an estate planning attorney before you name anyone as a direct beneficiary of an account, a life insurance policy, or a trust, since those beneficiary designations are often the first place families accidentally undo years of careful planning.
