There exist essentially two legal arrangements for someone who can’t manage their affairs: conservatorship and power of attorney. They serve similar purposes but differ significantly. How and when they’re established, and the authority they grant, should be key considerations when deciding between the two. Families face difficult but crucial decisions when caring for loved ones of diminished capacity due to age, illness, or disability.
A financial advisor can help guide you through the process of transferring assets and managing new accounts.
What Is a Power of Attorney?
Power of attorney lets a third party make legally binding or legally protected decisions. For example, say you assign someone financial power of attorney. This means they can access your bank accounts, pay your bills, and otherwise act in your place. When someone holds your power of attorney, third parties bestow the same authority and access that you would have.
This is an entirely voluntary assignment. You can give someone power of attorney by choice and can rescind it at any time. You can also specify the scope of a power of attorney assignment. A power of attorney can also be structured around timing. A “springing” power of attorney only becomes effective once a specific triggering event occurs. The most commonly form comes from a doctor who certifies that you’ve become incapacitated.
An immediately effective power of attorney, by contrast, grants authority the moment it’s signed. It takes effect regardless of your capacity at the time. A springing POA avoids handing over authority prematurely, but can require extra steps to formally activate when needed. An immediately effective POA is ready to use right away, but relies entirely on your trust. Whomever you name will have authority even while you’re still fully capable of managing your own affairs.
A specific power of attorney means someone can only act regarding a specific area, issue, or amount of time. For example, you might give someone power of attorney to negotiate a specific contract for you. This means that they can sign a deal that binds you for that negotiation. They couldn’t use it to access your bank accounts. Or you could assign someone power of attorney while you are traveling and will be unreachable. You can give them an assignment that automatically ends on the date of your return.
How Power of Attorney Works
The most common types of power of attorney are financial and medical. Financial assignments generally give the power of attorney access to your banking and finances. Medical power of attorney assignments generally occur generally while you are unconscious or otherwise incapacitated. They allow someone to make medical decisions on your behalf.
Someone with power of attorney cannot contradict or override your own decisions, but they can change your decisions at will. For this reason, it is rarely (if ever) a good idea to assign someone power of attorney while you’re capable. At best, that can lead to confusing, conflicted authority.
You do not need any formal process to assign a power of attorney. In most cases, you need only to sign a document specifying the assignment and have it notarized. However, you cannot assign power of attorney if you cannot make legally binding decisions. For example, someone who is heavily medicated might not be considered competent to understand his own actions. In that case, a court might strike down any power of attorney that the person assigns as invalid.
You also technically cannot revoke a power of attorney assignment if you lack mental competence at the time. The POA itself implies you lack the ability to take legally binding actions. However, in practice, courts are generally less strict about these conditions. Depending on the circumstances someone may be able to revoke a power of attorney assignment.
What Is Conservatorship?

A conservatorship is a legal assignment that a judge or hearing officer will make. In a conservatorship, the court will take away certain legal rights from one person. This court then assigns this person, now known as the “ward,” to a third party, known as the “conservator.” Like a power of attorney, a conservatorship covers the authority to make legally binding decisions.
However, a conservatorship can be significantly more sweeping. A conservator assumes the power to make personal, financial or medical decisions for their ward. For example, a conservator may assume the authority to manage their ward’s finances or sell their property. They can even tell their ward where to live.
Courts can assign either a general conservatorship or a specific one. In a general conservatorship, the conservator can make virtually any decision for the ward’s personal, medical and financial life. For this reason, general conservatorships are rarer, but not as rare as a general power of attorney. With a specific conservatorship, the court gives the conservator authority over specific aspects of the ward’s life.
For example, the court might assign a financial conservatorship. This allows the conservator to make decisions about the ward’s money and property but not their medical or personal decisions. In either case, the conservator has a fiduciary duty to the ward.
How They’re Different
Unlike with a power of attorney, a ward cannot overrule the decisions made by the conservator. In most cases, the ward loses all authority to make these decisions at all. For example, in a financial conservatorship, only the conservator would have access to the ward’s money and financial decisions. The ward would have no authority in those matters and would need the conservator to sign off on any withdrawals, personal loans, payments, or other transactions.
Judges will assign a conservatorship when they believe that the ward is no longer mentally competent to make their own decisions. Often, the judge will also need some sort of showing that this incompetence makes the ward a threat to themselves or others. In this case, “incompetence” has a specific legal context.
It means that the individual cannot understand the nature and quality of their actions. For example, the court may consider an elderly person suffering from dementia or an individual suffering from severe mental illness as legally incompetent. Someone who makes misguided decisions will not meet that standard.
A ward cannot rescind a conservatorship. Only a court order can rescind one, which means that the ward must file a formal legal challenge with a hearing. At the hearing, the ward must prove that circumstances have changed and they are no longer incompetent. Absent this proof, the conservatorship remains in place indefinitely.
How to Set Up Either Option
Setting up a power of attorney is usually straightforward and does not require court involvement. You choose an agent to act on your behalf, define the authority you want to grant, specify when that authority takes effect and sign the document according to your state’s legal requirements. Most states require notarization, and some also require witnesses. Many states provide standard forms for simple situations, while people with more complex needs often work with an estate planning attorney.
It’s also wise to name a successor agent. If your first choice dies, becomes incapacitated or is unwilling to serve, the successor can step in without disrupting the arrangement. Without a successor, your family may have to ask a court to appoint a conservator if no one has legal authority to act on your behalf.
Setting up a conservatorship is a court process. A family member or another interested party files a petition explaining why the individual can no longer manage personal affairs or financial plans. Courts typically require medical or psychological evidence showing that the person lacks the capacity to make those decisions independently.
The court then holds a hearing to review the evidence. The proposed conservatee may have legal representation, and the judge decides whether a conservatorship is necessary and who should serve as conservator. If approved, the court appoints a conservator, who may be a family member or, in some cases, a professional fiduciary.
Unlike a power of attorney, establishing a conservatorship can take weeks or months. Some states also allow temporary or emergency conservatorships when immediate action is necessary, with a full hearing scheduled afterward.
An estate planning attorney or financial advisor can help you understand your state’s requirements and decide whether putting a power of attorney in place now could reduce the need for a conservatorship later.
Can You Use Both a Conservatorship and a Power of Attorney?
Yes, sometimes you can use conservatorships and powers of attorney together, though they serve different purposes under different circumstances. A power of attorney allows someone to make decisions on another person’s behalf while they’re still competent but perhaps unable or unwilling to handle certain matters. Meanwhile, a conservatorship equals court-appointed oversight that typically comes into play when someone can no longer make sound decisions for themselves.
There are situations where both legal arrangements might be appropriate. For instance, someone might establish a power of attorney while they’re healthy, but if their condition deteriorates beyond what the power of attorney covers, a conservatorship might become necessary. The power of attorney might continue to handle certain matters while the conservatorship addresses others, particularly if the power of attorney remains effective even after incapacity.
It’s important to understand that a conservatorship can potentially override a power of attorney. Court-supervised conservatorships generally take precedence in cases of conflict. However, courts often respect previously established powers of attorney if they adequately address the person’s needs and were created when the individual was competent to make such decisions.
Working with a financial advisor who specializes in estate planning can help you determine whether you need both a conservatorship and a power of attorney. They can guide you through creating comprehensive legal protections that work together rather than conflict. The goal should always be to ensure your wishes are respected while providing the appropriate level of protection based on your specific circumstances.
Bottom Line
A power of attorney offers a proactive approach, allowing individuals to designate someone they trust while they still have capacity. Conservatorships, on the other hand, provide court-supervised protection when someone can no longer make decisions and hasn’t established alternatives. The right choice depends on your specific situation, timing, and the level of oversight needed. For most people, establishing a power of attorney early is the preferred option, as it respects personal autonomy and avoids court intervention.
