How Does Guardianship Affect Inheritance?
Families often worry that placing a loved one under guardianship will somehow rewrite who inherits from whom. It does not. Guardianship and conservatorship change who manages a person's affairs, not who is entitled to receive money when someone passes away. The Law Office of Chad Foster helps Snohomish County families with guardianship and conservatorship. Financial authority also matters when selling property belonging to a person under guardianship. Who inherits is a separate question governed by a will or Washington intestacy rules.
Guardianship Does Not Change Who Inherits
The first thing to understand is the difference between managing property and owning it. A guardianship or conservatorship is a management arrangement. When a court appoints someone to help a person who cannot fully manage their own life, it does not transfer that person's property to the appointee, and it does not alter the inheritance rights of anyone. A protected person continues to own their assets. Heirs and beneficiaries keep whatever rights they already had under a will, a trust, a beneficiary designation, or the state's intestacy rules. The appointment simply installs a responsible fiduciary to handle things during the protected person's life.
It also helps to separate the two roles the law creates. Washington distinguishes between a guardian, who makes decisions about a person's personal affairs, and a conservator, who makes decisions about property and financial affairs. Those definitions appear at RCW 11.130.010. A guardian focuses on care, health, and welfare. A conservator focuses on money and assets. Some people need one, some need both, and understanding which role is involved makes the inheritance question much clearer.
What a Conservator Does With a Protected Person's Assets
When a person cannot manage their own finances, the court can appoint a conservator to do it for them. The conservator's job is to manage and protect the estate, not to spend it freely or redirect it. Washington sets out the conservator's duties at RCW 11.130.505, which makes the conservator a fiduciary with duties of prudence and loyalty and directs the conservator to invest and manage the estate as a prudent investor would.
Crucially for inheritance questions, that same section, RCW 11.130.505, tells the conservator to consider the protected person's own estate plan. In investing, in selecting property for distribution, and in exercising powers over the person's assets, the conservator must consider any estate plan of the individual that is known or reasonably ascertainable, and may examine the person's will or other planning documents. In other words, the law expects a conservator to respect, not override, the protected person's existing plan for who receives what. The conservator manages the assets during the person's life and must account for them, but the person's chosen beneficiaries remain the people set to inherit.
A conservator cannot simply substitute a preferred inheritance plan. RCW 11.130.435 identifies estate-planning powers that require specific court authorization, including certain trust, gift, and beneficiary-designation actions. The appointment itself does not change the plan, but a court-authorized action may affect what ultimately passes. The protected person's welfare remains central.
Inheritances Coming Into a Guardianship or Conservatorship
The question also runs the other direction. What happens when a person under guardianship or conservatorship inherits money, or when a family wants to leave assets to someone who is protected? If a protected person receives an inheritance, those funds generally become part of the estate the conservator manages, subject to the same fiduciary duties, accounting requirements, and prudent-investor standard described in RCW 11.130.505. The money belongs to the protected person and is preserved and managed for their benefit.
This is where careful planning matters, especially when the protected person relies on public benefits. For someone receiving needs-based assistance such as Medicaid or Supplemental Security Income, a direct inheritance can unintentionally push them over asset limits and jeopardize eligibility. That is a benefits problem, not a guardianship problem, but it often surfaces in guardianship families. A commonly used tool is a special needs trust, which is designed to hold assets for a person with disabilities in a way that supplements, rather than replaces, their benefits, so an inheritance can help without disqualifying them. Whether a special needs trust fits, and how it must be structured, depends on federal and state benefit rules and on the individual's circumstances, so it is a planning decision to make with qualified advice rather than a do-it-yourself project.
Planning Ahead So Guardianship and Inheritance Work Together
The practical takeaway is that guardianship and inheritance are two different systems that need to be coordinated, not confused. If you are naming a beneficiary who is or may become subject to guardianship, thinking through how they will receive the gift, whether outright, through a trust, or by another route, can spare the family real trouble later. If you are already serving as a conservator and an inheritance arrives, handling it consistently with your fiduciary duties and the person's existing estate plan keeps you on solid ground.
For Snohomish County families, the smartest move is usually to align the estate planning documents with the guardianship reality before a crisis forces a rushed decision. The Law Office of Chad Foster helps families coordinate guardianship, conservatorship, and estate planning so that a protected person is cared for and an inheritance actually reaches its intended purpose.
