How much does it cost to speak with a Boston personal injury lawyer?

It costs nothing to speak with Gavagan Law about a potential injury case. We offer free consultations, and there is no fee unless we recover compensation for you. You pay nothing up front. If you are ready to talk, you can request a free case evaluation here.

What should I do after an accident in Massachusetts?

After an accident, seek medical attention, report the incident when appropriate, and preserve photos, records, and witness information if you can. Avoid giving recorded statements to the insurance company before getting legal advice. Acting quickly can help protect both your health and your claim. For more guidance, review our Boston car accident lawyer page.

What compensation may be available in a Massachusetts personal injury case?

Compensation may include medical bills, lost wages, reduced future earning capacity, pain and suffering, and other damages depending on the injuries, liability facts, and available insurance coverage. Every case is different, so the value of a claim depends on its specific facts. You can explore more case types on our Practice Areas page.

How long do I have to file a personal injury claim in Massachusetts?

Generally, under Massachusetts law, most personal injury claims must be filed within three (3) years of the date of the accident. However, certain cases involving government entities — including accidents involving municipal property, city or town negligence, or public transportation systems like the MBTA — involve shorter notice deadlines and additional legal requirements.

Under the Massachusetts Tort Claims Act, written notice of the claim (known as “Presentment”) must be provided to the appropriate government entity within two (2) years of the accident. Failing to comply with these requirements can jeopardize your right to recover compensation and pursue a claim.

Because these deadlines and notice requirements can vary depending on the circumstances of the accident, it is important to speak with an experienced Massachusetts personal injury attorney as soon as possible.

What should I do if the insurance company is calling me, blaming me, or offering quick money?

Be careful. Insurance adjusters may ask for recorded statements or push quick settlements before the full value of your injuries is known. Before agreeing to anything, it is often wise to speak with a personal injury lawyer who can help protect your rights and evaluate the claim.
