It is legal advice (and something lawyers actually get paid for) to tell you
whether you have a case. We do not provide legal advice here on able2know.
However, you can go to many, many personal injury lawyers and get a free initial consultation. Just contact your local Bar Association (they are in the telephone directory) for the names of some firms. Have all of your ducks lined up
before you go in for an appointment. As in, names, dates, records. Bring copies, not originals of any documentation you have.
You are going in for a consultation and are not retaining anyone. You are just asking whether they think you have a claim.
Shop around a bit as you will undoubtedly be charged 1/3 of any settlement or verdict plus court costs. You're not only looking at price, and how much they think they can get you in a verdict or settlement, you're also looking at how comfortable you are with any particular lawyer or firm. This is why I am suggesting copies and leaving the originals at home -- you are shopping around as if you were buying a car. So long as you are not close to the Statute of Limitations or any sort of time limit for any preliminary filings (requirements vary from state to state, so ask when you go in!), you should have a little time to shop.
Best of luck to you -- and I hope for a full recovery for your husband.
