It seems counterintuitive that lawyers would need to source their own malpractice insurance.  After all, do the people filing the malpractice suits really get sued themselves? Lawyers themselves can actually be sued for a number of reasons: claims of negligence, breach of confidentiality, administrative errors, missing filing deadlines, and professional misconduct.

You’ve probably heard of medical malpractice insurance or nursing malpractice insurance. Legal malpractice insurance is its litigation profession cousin. You might commonly see it referred to as lawyers professional liability insurance. It’s simply a type of insurance that protects lawyers when damages are claimed by the result of errors or omissions by the lawyer or colleagues.

For example, below are a couple incidents where this type of insurance is a must, in addition to the lawsuit reasons listed above:

  • When a client is awarded less than they hoped after a case
  • Errors made in applying statue or interpreting the law

In short, if someone claims damages because of a perceived error on the part of the lawyer, that lawyer could be sued.  

Often these lawsuits can be quite damaging. As listed by insurer Aon Attorney’s Advantage, the average jury awarded $198,878 as part of legal malpractice suits and 22 percent of jury awards are over $1 million.  

As such, you’ll often see coverage that runs in the millions. For instance, a plan may offer $1 million per claim and $3 million aggregate.

When looking for malpractice insurance for attorneys, it’s important to make sure you’re working with an insurer, broker or agency that can write a custom plan for your type of practice or law firm. For instance, Aon Attorney’s Advantage offers coverage for everyone from solo general practitioners to specialty firms that handle riskier cases. The higher the risk and the larger the firm, the more coverage you are likely to need.

Unlike other types of insurance, legal malpractice insurance tends to be offered on a claims-made basis. According to insurer ALPS, claims-made policies mean that claim has to be filed while the policy is in effect in order to be covered, versus occurrence where the event alone has to happen while the policy is in effect.

You may also see the term “retro date” on claims-made legal malpractice policies, which is usually the date after which the negligent act can happen. The American Bar Association gives the example that a policy period may run from Aug. 15, 2009, to Aug. 15, 2010, but have a retro date of Jan. 1, 2003. The claim has to happen during that one year of policy effectiveness, but the malpractice event can happen Jan. 1, 2003 or later.

Malpractice insurance for attorneys is another one of those insurance types where the cost can vary greatly based on a number of factors.

  • Size of your law firm: larger law firms have higher rates
  • Prior claims: a claims history can mean more expensive policies
  • Coverage amount: this factor most directly affects premiums, since more coverage is more expensive to carry
  • Deductible: higher deductibles mean lower premiums, since you’re paying a higher amount for coverage to take effect
  • Length of time with a firm: premiums tend to increase the first few years a lawyer is at a firm because the lawyer amasses more cases and thus more risk – however, premiums tend to even out around the sixth year
  • Location: denser populations can increase risk of claims and boost premiums
  • Type of practice: some practice types naturally have higher risks attached to them because of their complexity, like securities or medical malpractice, which can increase premiums
  • Risk management: in some cases, you could have lower premiums if you demonstrate that you have a risk management policy in place

L Squared lists some premiums as examples:

  • Annual premiums can run $300 to $500 for a new attorney in a low-risk practice.
  • Average costs run around $1,200 to $2,500 per year.
  • Higher risk attorneys can pay $3,000 to $10,000 per year. 

Attorneys and lawyers practicing in the areas of practice of medical malpractice, intellectual property, oil and gas, class action, mass tort, securities, and even mergers and acquisitions are considered high-risk. These are the areas of practice that have something called claims severity, ie. these claims usually results in large settlement amounts. Medical malpractice claims, patent mistakes, and patent infringement are typical in these high-risk areas of practice. Many carriers actually refuse to underwrite policies in these areas. If they do, they often offer lower coverage with higher premiums.

Unlike medical malpractice insurance which is required in all states, legal malpractice insurance isn’t required, except Oregon where all practicing attorneys are required to have a malpractice policy. However, many lawyers and attorneys still choose to have a malpractice insurance policy to protect themselves from law suits. It may be necessary given it is estimated that 5-6% of all attorneys are sued each year due to malpractice.

However, more and more states require attorneys to disclose to their clients if they do not have legal malpractice insurance. Help Abolish Legal Tyranny (HALT) group has successfully lobbied for disclosure laws in 26 states, including Alaska, Ohio, New Hampshire, California, Colorado, Washington, South Dakota, Delaware, Virginia, Nebraska, and North Carolina, etc.

If you are a new solo practitioner, you may want to become insured to protect yourself.

Does My Firm’s Malpractice Insurance Policy Cover My Pro Bono Work or Moonlighting?

You definitely need to check with your managing partner if the firm’s policy covers your pro bono or moonlight work. Don’t assume that it does. If you work for your own firm as a solo practitioner, you need to check with your insurance agent when you are buying malpractice insurance.

Do I need Malpractice Insurance If I Join a Small Company as an In House Counsel?

There is a special policy for inside counsel. You need to check with your employer. You may also want to discuss with a malpractice insurance agent or broker to get their advice. This coverage is usually referred to us “Employed Lawyers Coverage”. It may not cover your work in pro bono or moonlighting capacity.

What Do ‘Retro Dates’ Mean in Attorney Malpractice Insurance?

The term ‘retro date’ or ‘dates’ simply refers to a retroactive period to your current insurance coverage activation date. Sometimes, lawyers will purchase insurance with a retroactive date that covers work done for clients in the past to provide additional protection. 

Retroactive coverage may be necessary for a few reasons; the lawyer didn’t have insurance when they were working during these periods, or they had insurance, but the previous policy no longer covers them. A retroactive insurance may also be called, ‘prior acts coverage.’

What is ‘Innocent Insured’ Coverage in Attorney Malpractice Insurance?

If you are part of a practice or an employer who hires in-house counsel, you may want to get legal malpractice insurance for attorneys with an additional ‘Innocent Insured’ clause. This clause is a common addition to legal malpractice insurance that is designed to provide coverage for companies and law offices. 

Most insurance providers require lawyers to tell them about any previous acts that they could be sued over during the application process. The innocent insured clause means that law firm won’t lose their policy if one member of the firm doesn’t disclose a potentially pre-existing legal claim.

If that attorney is sued over the incident, this usually results in the insurance provider rescinding the policy, but the firm can point to the innocent insured clause saying they were kept in the dark about the prior claim. So, the law firm is able to keep their legal malpractice insurance coverage.

What is ‘Tail Coverage’ in Attorney Malpractice Insurance?

Although it’s called, ‘Tail Coverage,’ this is actually an extension of your last insurance policy with an ‘Extended Reporting Endorsement.’ When you leave a practice, and unable to work as a lawyer any longer, or retire, your existing legal malpractice policy will end. If you don’t purchase an extension you won’t be covered by malpractice insurance if sued later for a prior act. However, the tail coverage keeps your coverage active even in retirement. 

Most insurance providers have strict rules for tail coverage, such as:

  • Only providing a 30-day window to purchase the Extended Reporting Endorsement
  • Not allowing coverage of work completed after retirement or injury
  • No allowing you to increase the limits on your prior coverage
  • Requiring lawyers to renew their Extended Reporting Endorsement every year or every five years

How Do I Determine How Much Attorney Malpractice Insurance I Need?

It’s up to each person to decide how much coverage they require, but your insurance agent or broker can help you determine the ideal amount for your needs. It’s important to look at how much you are willing to pay in premiums and what level of risk is involved in your area of practice.

Generally, those operating in legal fields where clients can potentially lose large amounts of money on a failed defense or poor piece of legal advice will need a lot of coverage. 

These high-loss areas of practice can include:

  • Real Estate Law
  • Corporate Organization & Securities
  • Trusts & Estate Law
  • Commercial Business Transactions
  • Tax Law
  • Plaintiff and Intellectual Property Law

For instance, if you work in corporate tax law and advise the client on a series of deductions that the IRS later denies and charges a fine over it could mean millions in losses for the client. If the client decides to sue, whether the case has merit or not, it could mean you are on the hook for a multi-million-dollar settlement. 

Where Can I Buy Attorney Malpractice Insurance?

Many insurance companies offer attorney malpractice insurance across the United States. You can find a full listing of providers on the American Bar Association’s website. We recommend that you work with a national broker specializing in small business insurance such as CoverWallet or Simply Business. They will allow you to compare quotes from leading insurance companies in one place.

In 2018, the statute of limitations for tort claims of legal malpractice in Wisconsin was shortened from six years to three years. Great, you think! I can finally stop worrying about Troublesome Client X, whom I represented four years ago. Not so fast. Since the attorney-client relationship is recognized as a contractual relationship, Troublesome Client X can technically sue for breach of contract, for up to six years. 

There is also some leeway as to when a tort claim can be filed. All of this means you need to keep your records on file for at least six years, and if a client was problematic, it’s a good idea to keep them longer. 

Colorado lawyers in private practice are required to report to the Supreme Court about whether or not they have legal malpractice insurance. Note that actually having malpractice insurance is not required, but you do need to report it annually. Even though about 15% of Colorado lawyers in private practice don’t have any legal malpractice insurance does not mean it’s a good idea. As a lawyer, you should know anyone can get sued. 

You’re not required to carry legal malpractice insurance in Florida, but you are required to report whether or not you have it every year. And Florida not only has an abundance of sunshine, they also have an abundance of lawsuits. It used to be on the list of judicial hellholes, but Florida fell off the list in 2019, due to tort reform. However, this might come as news to residents of Florida, who have a reputation as being very litigious, especially for personal injury cases. 

California is second on the American Tort Reform Association’s (ATRA) list of the top 10 Judicial Hellholes. Part of the reason for this is because California created new laws regarding whether someone was or was not an employee (as opposed to just calling them independent contractors), to protect gig workers at companies like Uber, Doordash, Instacart, etc. These laws may be a good thing, but they opened themselves up to endless wage and hour lawsuits, thus ranking it as a judicial hellhole. 

All of it is to say if you are an attorney or a lawyer in California, you should seriously consider having proper legal malpractice insurance.

Alabama attorneys are not required to carry malpractice insurance (most states don’t require it—if you’re curious, see the table of legal malpractice insurance requirements by states above.

Alabama isn’t super litigious, but it’s still a good idea to protect yourself with a proper legal malpractice insurance.

New Jersey is the other “Judicial Hellhole” on this list, according to American Tort Reform Association. New Jersey is number ten on the list, mostly due to high-profile lawsuits against Amazon and other behemoths. Also, you can get sued for anything in New Jersey—some middle school teacher got sued just for telling a baseball player to slide into third base. So, yes, you need to be careful in New Jersey. If you are practicing in New Jersey, it is a good idea to have sufficient legal malpractice insurance coverage.

Plaintiffs in Maryland who want to sue an attorney need to show three things:

  • The attorney was working as your lawyer
  • They neglected a reasonable duty
  • The client suffered as a result of that neglect

Since you are a lawyer, you should know that this fairly subjective language can result in years of litigation. There is a three-year statute of limitations, but there is also some question about when the statute begins (when you were hired? During the initial consultation? After you cashed the first check?). 

Attorneys in Arkansas are not required to carry legal malpractice insurance. However, since at any given time, about 5% of practicing lawyers are being sued for malpractice, you should consider protecting yourself. Arkansas is in the bible belt, so the state skews conservative, but most people are friendly and love to talk to pretty much anybody. However, that doesn’t mean they won’t sue you.

Final Thoughts

Even lawyers themselves can get sued if someone claims damages due to an error or omission on their part. That’s where legal malpractice insurance can help protect against these claims. Prices can go from hundreds to thousands per year, depending on a number of factors. Because malpractice insurance for lawyers is so specialized, it pays to shop around with companies directly.
