Oh, yes. If the conservator isn't performing their due diligence and you can point to any negligence on their part. Not only will the judge remove them but they may be liable for their inaction too.
Malfeasance is a comprehensive term used in both civil and Criminal Law to describe any act that is wrongful. It is not a distinct crime or tort, but may be used generally to describe any act that is criminal or that is wrongful and gives rise to, or somehow contributes to, the injury of another person.
Malfeasance is an affirmative act that is illegal or wrongful. In tort law it is distinct from misfeasance, which is an act that is not illegal but is improperly performed. It is also distinct from Nonfeasance, which is a failure to act that results in injury.
The distinctions between malfeasance, misfeasance, and nonfeasance have little effect on tort law. Whether a claim of injury is for one or the other, the plaintiff must prove that the defendant owed a duty of care, that the duty was breached in some way, and that the breach caused injury to the plaintiff.
I think that given the facts you stated - you could have a review by the judge of the conservator's inactions and negligence and have them removed. Whether there is a negligence claim where you could pursue their malpractice insurance may be an issue. If they didn't act when they knew they should have - they very well may be liable.
As stated as to the duties of a conservator:You have a fiduciary duty to the protected person, meaning that you must always act in the best interest of and with undivided loyalty to the protected person, avoid transactions that cause a conflict of interest, and administer the conservatorship estate with care and prudence.
You must always act in the best interest of the protected person. You should not enter into transactions in which you will benefit at the expense of the protected person. In some instances, you may need to get the approval of the Court before finalizing any transactions.
You must keep the conservatorship estate separate from your own assets, and the assets must be readily indefinable.
You must manage the conservatorship estate as a prudent person would in similar circumstances. You are ultimately accountable and may employ the use of professionals and other agents in order to carry out your duties, unless otherwise specified by the Court,
The Court may require you to obtain a type of insurance policy called a “fiduciary bond.” The bond assures that the protected person’s assets are protected in the event that you fail to carry out your duties and there is a loss to the conservatorship estate. If a bond is required, it is generally paid for with the protected person’s funds.
