What Is the Hunter Formula Under MGL 152 15 Workers Comp Lien Rules?
The Hunter formula is the method Massachusetts uses to make the workers’ compensation insurer bear its share of attorney’s fees that produced a third-party recovery. Under the MGL 152 15 workers comp lien, the comp insurer that paid your benefits after a Worcester crash holds a statutory right of reimbursement on money you recover from the negligent driver. M.G.L. c. 152, § 15 states that "the expenses of attorney’s fees shall be divided between the insurer and the employee in proportion to the amounts received by them respectively." The insurer shares the cost of the lawyer who produced the recovery.
Hunter v. Midwest Coast Transport, Inc., 400 Mass. 779 (1987) held that the insurer pays its share of fees and costs attributable to a third-party recovery by paying a proportionate fraction of the employee’s post-recovery claims as they arise, until the total equals the statutory "excess."
In practice, where a one-third contingency fee applies, the insurer’s reimbursement is commonly negotiated down by roughly one-third as its proportionate share, though the exact figure depends on the fee agreement, the amounts each side receives, and approval by the court or the Department of Industrial Accidents (DIA).
You were hurt doing your job, and now an insurer wants a large piece of the settlement you fought for. That does not have to be the outcome. Call Ballin & Associates, LLC at 508-882-2853 or request a free consultation today.
A work-related collision on Route 9, I-290, or a Worcester side street is really two claims at once. One is a workers’ compensation claim against your employer’s carrier, and the other is a bodily injury claim against the at-fault driver, which is where our Massachusetts car accident attorneys go to work. How these claims interact decides how much money you keep.

You Can Take Workers’ Comp and Still Sue the Driver Who Hit You
Massachusetts law does not force you to choose. Under M.G.L. c. 152, § 15, where a party other than your employer is legally liable for the injury, the employee is entitled "without election" to compensation benefits and may still pursue the third party.
The statute also provides that either the employee or the insurer may proceed to enforce that liability, although the insurer may not do so until compensation has been paid and not until seven months after the date of injury.
Because the tort claim is governed by the three-year statute of limitations for personal injury, acting early on a Worcester third party injury claim matters.
This applies to public safety workers. Ballin & Associates, LLC is dedicated to injured police officers, firefighters, and public safety officers, and an officer rear-ended in a cruiser generally has both a comp claim and a claim against the driver. The same applies for delivery drivers, home health nurses driving between visits, or municipal workers.
How the Comp Insurer’s Lien Attaches to Your Worcester Settlement
The lien is created by statute, not by contract. M.G.L. c. 152, § 15 provides that the sum recovered "shall be for the benefit of the insurer, unless such sum is greater than that paid by it to the employee, in which event the excess shall be retained by or paid to the employee."
The insurer is reimbursed out of your recovery, and whatever is left over is yours, subject to the fee-sharing rules below.
What "Excess" Means in Plain English
The statute defines "excess" as the amount by which the gross sum received in payment for the injury exceeds the compensation paid under Chapter 152. Gross recovery minus what the comp carrier paid equals the statutory excess. That number determines what lands in your pocket now and what happens to your benefits later, and, under Hunter, the employee’s share of attorney’s fees and costs is accounted for so the insurer’s offset does not exceed the employee’s net recovery.
Section 15 Attorney Fees: The Insurer Pays Its Share
Section 15 attorney fees are not your burden alone. Because the comp insurer benefits from the recovery through its lien reimbursement, the statute requires it to bear a proportionate share of the fees that produced that money. That is why the number the adjuster first demands is rarely the number ultimately approved.
Ballin & Associates, LLC handles personal injury law and nothing else. That focus is why the firm runs the apportionment math before any lien figure is accepted. The allocation is subject to negotiation and approval by the court or the DIA.
A Worcester Example: Running the Numbers on a $300,000 Crash Settlement
Here is a simplified hypothetical illustration only, not a past result. Assume a Worcester County delivery driver is struck by a negligent motorist, the comp carrier pays $90,000 in indemnity and medical benefits, and the third-party case settles for $300,000 under a one-third contingency arrangement.
| Item | Amount |
|---|---|
| Gross third-party settlement | $300,000 |
| Comp benefits paid (gross lien) | $90,000 |
| Insurer’s proportional fee share (1/3 of $90,000) | $30,000 |
| Net lien repaid to comp insurer | $60,000 |
| Statutory "excess" ($300,000 – $90,000) | $210,000 |
In this illustration, the Massachusetts Section 15 fee allocation moved $30,000 from the insurer’s column to yours. That is workers comp lien reduction fees in action, and further negotiation or an approved allocation can affect the result. Hunter governs how fees are accounted for against the statutory excess.
💡 Pro Tip: Ask for the comp carrier’s full benefit printout early. Liens are frequently overstated with charges unrelated to the crash injury.
Costs Are Not Fees, and That Distinction Is Worth Money
MGL 152 Section 15 fees and litigation costs follow different rules. The statute provides that the party which brings the action or pays the costs associated with it is entitled to retain those costs recovered in the action. Costs such as filing fees, deposition transcripts, and accident reconstruction are generally treated differently from the proportional fee split.
Interest, by contrast, is apportioned like fees. Section 15 apportions any interest received in the action between insurer and employee in proportion to the amounts received by them, exclusive of interest and costs.
What Happens to Your Future Medical Bills After the Settlement?
Once an "excess" exists, your benefits change shape. Section 15 does not expressly address the insurer’s right to offset the excess against future compensation, but that right was recognized in Richard v. Arsenault, 349 Mass. 521 (1965), which treats the excess as an offset against future compensation payments to prevent double recovery.
Under Hunter, the insurer must nonetheless keep paying a proportionate fraction of covered benefits as they arise; where a one-third fee applies, that commonly means the insurer pays about 33.3% and the employee absorbs the balance out of the excess until the excess is exhausted.
Allocation is one defense. Amounts fairly allocated to a spouse’s or child’s loss of consortium claim are generally not subject to the comp insurer’s lien or offset, and allocations to pain and suffering are sometimes argued as well. Whether any allocation is approved is fact-dependent, requires supporting evidence, and rests with the judge.
Getting the Settlement Approved in Worcester
Approval is not a formality. Except for a settlement made during trial, M.G.L. c. 152, § 15 permits no settlement by agreement without approval of the board, the reviewing board, or the court in which the action was commenced, after a hearing where both employee and insurer have an opportunity to be heard. In Worcester County, that usually means Worcester Superior Court or the Department of Industrial Accidents.
The judge decides more than one number. At approval, findings generally address:
- The fair allocation of amounts payable to the employee and the employee’s spouse, children, and parents
- The amount, if any, the insurer is entitled to by way of reimbursement
- The amount of excess subject to offset against future benefits
Where the parties cannot agree, either side may petition for a hearing. You can review the Section 15 petition process at the Department of Industrial Accidents. A Worcester workers comp lien attorney prepares that record in advance, and readers can find more articles on Massachusetts injury claims for additional guidance.
Frequently Asked Questions
-
Does the workers’ comp insurer have to pay part of my attorney’s fee in Massachusetts? Generally yes. M.G.L. c. 152, § 15 divides fees between insurer and employee in proportion to the amounts each receives, so the carrier’s reimbursement is typically reduced by its share, subject to court or board review.
-
What is Hunter v. Midwest Coast Transport and why does it matter to my settlement? The Hunter v Midwest formula MA practitioners cite comes from Hunter v. Midwest Coast Transport, Inc., 400 Mass. 779 (1987). It requires the insurer to pay its share of fees and costs by paying a proportionate fraction of the employee’s post-recovery claims until they equal the statutory excess.
-
Who approves a third-party settlement in Worcester, the court or the DIA? Either can, depending on posture. If suit is pending, the court where the action was commenced generally approves it after a hearing; otherwise the board may, and any Worcester third party injury claim with a comp lien needs approval.
-
Will I have to pay part of my own medical bills after I settle? Possibly. Once an excess exists, the offset can leave you responsible for a share of related medical costs until the excess is used up, which is why the findings and allocation at approval matter.
-
Can the lien amount itself be challenged? In many cases, yes. Unrelated charges, duplicate billing, and disputed causation are all fair grounds, though results depend on the medical record.
