The Bottom Line

In most Massachusetts personal injury cases, you pay your lawyer nothing upfront. Attorneys work on contingency, meaning they’re only paid a percentage of your settlement or verdict if you win. Case costs (filing fees, expert witnesses, etc.) are usually advanced by the firm too, then repaid out of your recovery.

That’s the short version. Here’s what actually goes into the cost of hiring a personal injury lawyer in Massachusetts, and the questions worth asking before you sign anything.

What Is a Contingency Fee, Exactly?

⚖️ Key Rule

A contingency fee means your lawyer only gets paid if your case wins. Instead of billing by the hour, you and your attorney agree upfront on a percentage of whatever you recover. No recovery generally means no attorney fee, though case expenses may still apply, depending on your written agreement.

A contingency fee just means your lawyer’s payment depends on your case resulting in a recovery. No recovery, no attorney’s fee. Instead of billing you by the hour as the case moves along, you and your lawyer agree upfront on how the fee gets calculated if (and only if) money comes in.

Massachusetts allows this kind of arrangement, but it has to follow some rules. The agreement must be in writing, signed by both of you, and spell out the key details: what triggers payment, how the fee is calculated, and how expenses get handled. See Massachusetts Rule of Professional Conduct 1.5 for the full rule.

There’s no single “standard” percentage that applies to every case in Massachusetts. It varies by firm and by case, and it should be spelled out in plain language before you ever sign on.

Attorney Fees vs. Case Expenses: Two Different Buckets

A contingency fee doesn’t mean your case is free. It means your lawyer’s time is free unless you win. Case expenses are a separate bucket entirely, and a solid fee agreement should spell out both.

Some cases are simple and inexpensive to prosecute. Others need serious investigation, expert testimony, or a full trial, and the expenses increase accordingly.

Who Pays the Upfront Costs, and When Do You Pay Them Back?

💰 Who’s on the Hook

Most Massachusetts firms advance case expenses out of pocket and only get reimbursed from money they actually collect for you. You’re typically not personally on the hook for those costs if there’s no recovery, but confirm this in writing, since other lawful fee arrangements do exist.

This is the question that actually matters most: who fronts the money for expenses while your case is pending, and are you on the hook if you lose?

Under the standard approach most Massachusetts firms use, the lawyer advances the out-of-pocket costs, and you’re not personally liable for them except out of money the lawyer actually collects for you. Other lawful arrangements exist too, but whichever one applies to your case, your agreement should say so in plain terms. No guessing.

What Happens If You Don’t Win?

In most personal injury cases, the entire point of a contingency arrangement is that the fee only comes from a recovery: settlement, judgment, or otherwise. But “most cases” isn’t a guarantee for your case. The written agreement controls, and Massachusetts law requires it to spell out whether you could owe anything beyond what the lawyer actually collects, and how expenses get handled either way.

What If You Switch Lawyers Partway Through?

Sometimes the attorney-client relationship ends before a case ends. You’re allowed to make that call. Massachusetts Rule of Professional Conduct 1.16 covers how and when a lawyer can withdraw or be discharged. If that happens, a lawyer who wants to be paid for work already done has to have disclosed that possibility in the original agreement. If a new lawyer takes over, your agreement should also say who’s responsible for any fees that might be owed to your former attorney, you or the new firm.

At the end of a contingency case, your lawyer has to give you a written statement showing exactly how the numbers worked out. And if you ask in writing before the case resolves (or the representation ends), you can generally get an itemized breakdown of services and expenses within twenty days.

Medical Malpractice Cases Play by Different Rules

⚖️ Fee Caps at a Glance

Massachusetts caps attorney fees in medical malpractice cases on a sliding scale: 40% of the first $150,000 recovered, 33⅓% of the next $150,000, 30% of the next $200,000, and 25% of anything above $500,000. There’s also extra protection so you aren’t left with less than your unpaid medical bills.

If your case is a medical malpractice claim, the usual contingency-fee rules don’t fully apply. Massachusetts law caps how much a lawyer can charge in these cases: 40% of the first $150,000 recovered, 33⅓% of the next $150,000, 30% of the next $200,000, and 25% of anything above $500,000. There’s also extra protection built in so you aren’t left with less than your unpaid medical bills after fees and expenses. See Mass. Gen. Laws Chapter 231, Section 60I for the exact language.

Questions Worth Asking Before You Sign

No one can tell you exactly what your case will cost or what it’s worth. That depends on your injuries, how clearly negligence can be established, the evidence, the insurance involved, and a dozen other case-specific factors. If you want a clearer picture of what your specific claim might involve, it helps to talk it through with someone who handles these cases regularly. Butters Brazilian LLP’s Massachusetts personal injury lawyers can walk you through your options and what the fee structure would look like for your case, including the types of compensation you might be able to recover and how the claims process typically unfolds from here.
