Co-guardians generally cannot act independently of each other. In most states, the default rule is that all co-guardians must agree before taking any action affecting the person under their care, and a single co-guardian can act alone only when the court order specifically grants that independent authority. Whether co-guardians can act independently is controlled entirely by the language of the appointment order, so the first thing to do is read it and know exactly what it allows.
The Joint-Action Default
When a court appoints co-guardians and the order says nothing about independent authority, the assumption is joint authority. Both guardians must participate in and consent to decisions, large or small. Many people named as co-guardians assume the title lets them handle things on their own when their counterpart is unavailable. It does not.
This default exists because guardianship is a court-supervised arrangement built around protecting someone who cannot fully protect themselves. Requiring agreement between co-guardians adds a layer of oversight. Guardianship is governed by state law, and each state has its own statutes, so specifics vary from one jurisdiction to the next.1U.S. Department of Justice. Guardianship: Key Concepts and Resources The joint-action default is the prevailing approach. If you want the ability to act alone as a co-guardian, the order has to say so explicitly.
What Your Court Order Can Grant
Courts have flexibility to divide responsibilities between co-guardians in whatever way best serves the protected person. The court order appointing a guardian should specify the scope of that guardian’s authority.1U.S. Department of Justice. Guardianship: Key Concepts and Resources Some orders grant each co-guardian full independent authority, so either one can make any decision without consulting the other. Others split responsibilities by category. One co-guardian might handle medical decisions while the other manages finances. Still others grant independent authority only for routine matters and require joint consent for major ones.
Courts weigh several practical factors when deciding how to structure that authority:
- Geographic proximity. Co-guardians who live far apart often receive broader independent authority for day-to-day care, because requiring joint consent for every routine decision would create unworkable delays.
- Relationship dynamics. When co-guardians have cooperated well in the past, courts may be more comfortable granting independence. A history of conflict pushes courts toward requiring joint action.
- Complexity of the ward’s needs. Someone with significant medical and financial needs may require the check-and-balance of joint decision-making; a simpler situation may not.
- Nature of the decision. Courts commonly allow independent action for routine care like scheduling appointments or buying groceries, while reserving joint consent for major financial transactions, changes in living arrangements, or significant medical procedures.
Courts increasingly tailor co-guardian authority rather than issuing broad orders, so the answer to what you can do alone lives in the specific language of your appointment. If the order is unclear, ask the court to clarify it before you act.
Decisions That Almost Always Require Both Guardians
Even when a court order grants some independent authority, major decisions almost always require both co-guardians to agree. Decisions with lasting consequences deserve more deliberation, and requiring two people to sign off reduces the risk of impulsive or self-interested choices.
Decisions that typically require joint consent include:
- Financial transactions such as selling property, making large withdrawals, changing investment strategies, or entering contracts on the ward’s behalf.
- Major medical decisions like consenting to surgery, changing long-term treatment plans, or agreeing to experimental procedures.
- Living arrangements, including moving the ward to a different facility, changing their residence, or placing them in a more restrictive setting.
- Legal matters such as filing lawsuits, settling claims, or making decisions about the ward’s legal rights.
Financial institutions add their own layer of practical requirements. When co-guardians manage a ward’s accounts, the bank typically sets up signature cards reflecting whatever the court order requires. If the order mandates joint authority, both co-guardians usually need to authorize withdrawals and sign checks. If independent authority exists, either co-guardian can transact alone. Getting the bank’s records aligned with the court order matters, because a bank that allows a single co-guardian to drain an account when joint consent was required shares in the problem.
Emergencies When You Cannot Reach the Other Guardian
The hardest practical question for co-guardians is what happens when a genuine emergency arises and one co-guardian is unreachable. A medical crisis that requires immediate consent will not wait for a phone call to go through.
Most states recognize some form of emergency authority that allows a guardian to act without following the usual procedural requirements when delay would cause serious harm. Some states have specific provisions for emergency guardianship lasting 72 hours or more. Even in joint-authority arrangements, courts generally do not expect a co-guardian to let a ward suffer harm because they could not reach their counterpart in time.
Emergency authority is narrow. It covers situations where the ward faces immediate risk to health or safety. Using “emergency” as a justification for decisions that could have waited is the kind of overreach courts punish. If you act alone in a real emergency, document everything: what happened, why it was urgent, what you tried to do to reach the other co-guardian, and what decision you made. Then notify the other co-guardian and the court as soon as possible. A well-documented emergency decision rarely causes problems. An undocumented one looks like a unilateral power grab.
What Happens if You Act Outside Your Authority
A co-guardian who makes decisions outside the scope of their court-ordered authority faces real consequences. Courts take unauthorized guardian actions seriously because the entire guardianship system depends on guardians respecting the boundaries the court set.
The consequences escalate based on severity:
- Court sanctions and removal. A co-guardian who repeatedly ignores joint-consent requirements can be removed from the guardianship entirely. The court may transfer all decision-making authority to the other co-guardian or appoint a replacement.
- Civil liability. A co-guardian who causes financial harm through unauthorized actions can be held personally liable for repayment. This includes unauthorized withdrawals, bad investments made without required consent, or selling property without approval.
- Criminal charges. In serious cases, unauthorized handling of a ward’s money or property can result in prosecution for financial exploitation or embezzlement. Every state has laws targeting financial abuse of vulnerable adults, and guardians are not exempt.
The ward’s interests sit at the center of all guardianship proceedings, and courts have broad discretion to restructure arrangements when a guardian acts outside their authority.1U.S. Department of Justice. Guardianship: Key Concepts and Resources In extreme cases, the court might remove both co-guardians and appoint a professional guardian, which pulls money from the ward’s estate and signals a complete breakdown of the original arrangement.
You Can Also Be Liable for What the Other Guardian Does
One question that catches co-guardians off guard is whether they can be held responsible for the other co-guardian’s misconduct. The general fiduciary principle, applied across trusts and guardianships alike, is that co-fiduciaries share responsibility. A co-guardian who knows the other guardian is mismanaging funds or neglecting the ward and does nothing about it can face personal liability for those failures.
Shared liability typically arises in three situations: when one co-guardian knowingly participates in or helps conceal the other’s misconduct, when one co-guardian’s own negligence enables the other to commit a breach, and when one co-guardian learns about a problem and fails to take reasonable steps to fix it. Simply looking the other way is not a defense. Co-guardians have an affirmative duty to monitor each other and to report problems to the court.
Courts also require guardians to post surety bonds in many cases, particularly when the guardian manages the ward’s finances. A surety bond compensates the ward if the guardian mishandles estate assets. The court sets the bond amount based on the value of the estate, and the guardian pays an annual premium that typically runs around 0.5% to a few percent of the bond amount, depending on the guardian’s credit history and the size of the estate. Whether co-guardians post a single joint bond or individual bonds depends on the jurisdiction and the court’s preference.
When You Disagree and Cannot Resolve It
Disagreements between co-guardians are common. The worst thing two co-guardians can do is let a dispute paralyze decision-making while the ward’s needs go unmet.
Mediation is often the first step. A neutral mediator helps the co-guardians work through their disagreement and find a solution both can accept. Some jurisdictions require mediation before the court will hear a guardianship dispute. Mediation tends to be faster and cheaper than a court hearing, and it preserves the working relationship between co-guardians better than adversarial litigation does.
When mediation fails or the issue is too urgent, either co-guardian can petition the court for a ruling. The court evaluates each guardian’s position in light of the ward’s best interests, not the guardians’ personal preferences. The court may hear testimony from medical professionals, social workers, or other experts. In many cases, the court appoints a guardian ad litem to independently investigate and represent the ward’s interests. A guardian ad litem acts as a factfinder, making recommendations to the court based on what is best for the ward rather than advocating for either co-guardian’s position.
The court’s resolution often includes guidelines for handling similar decisions in the future, which can prevent the same type of dispute from recurring. If disagreements are chronic and harmful, the court may use the dispute as grounds to restructure the arrangement entirely, including switching to a single-guardian model.
If the Other Co-Guardian Dies or Steps Down
The death or resignation of one co-guardian does not automatically transfer full authority to the survivor. When a guardian dies, their authority terminates immediately. The surviving co-guardian needs to return to court to have the arrangement formally updated, which may mean petitioning for appointment as sole guardian or requesting that a new co-guardian be appointed.
Until the court acts, the surviving co-guardian’s authority may be limited to whatever the original order granted them individually. If the original order required joint consent for major decisions, the surviving co-guardian may lack authority to make those decisions alone, even though there is no longer anyone to consent with. That gap creates urgency. Acting promptly to petition the court avoids a period where critical decisions cannot legally be made.
Some states allow for standby guardians, who are pre-designated to step in immediately when a guardian dies or becomes incapacitated, subject to court confirmation within a set timeframe. If succession planning matters to you, ask the court about designating a standby guardian when the co-guardianship is first established.
Habits That Keep You Inside Your Authority
Read your court order carefully and understand exactly what it allows you to do alone and what requires the other co-guardian’s agreement. If the order is unclear, ask the court for clarification before acting, not after. Courts prefer questions to cleanup.
Keep a written record of every significant decision, including who made it, when, and why. Document any attempts to reach the other co-guardian and the outcome. If you disagree with a decision the other co-guardian wants to make, put your objection in writing. These records matter enormously if a dispute later ends up in court.
Communicate regularly with your co-guardian about the ward’s needs, finances, and any changes in circumstances. Most co-guardian conflicts escalate not because the guardians hold fundamentally different views about the ward’s best interests, but because one guardian felt blindsided by a decision they should have been consulted on. The guardian’s core obligation is to promote the protected person’s well-being, involve them in decisions to the greatest extent possible, and respect their preferences and values.1U.S. Department of Justice.
