In thinking through how to deal with your mom's property while preserving her eligibility for Medicaid for nursing home care, you should immediately consult an elder law specialist in your area. This is more complicated than you can deal with adequately through any internet legal forum. See http://www.michbar.org/generalinfo/libraries/elderlaw.cfm
Most states have some version of a "dram shop" law under which a person injured by a customer of a bar or restaurant who was served alcohol when visibly intoxicated (or some language generally along those lines) can sue the bar for its negligence in suing a drunk. Sometimes the bar is the last target in line after the drunk driver's insurance and uninsured / underinsured motorist coverage is exhausted or at least determined to be inadequate. Often the identity of the bar is unknown until the...
Some lawyers handle both personal injury (tort) and workers compensation cases, though these are radically different system. Many of us do one or the other but not both. You need an experienced workers compensation lawyer in your city. Workers compensation provides for income loss on a limited scale and medical expense, but not for pain and suffering. It is normally your only remedy with regard to your employer.
Your question is absolutely unintelligible. If you signed a release, you signed it and you're done. If you signed something equivalent to a power of attorney authorizing someone else to release your claim for you, and they signed a release for you within the scope of authority you granted in writing, you are done. If an attorney somehow defrauded you, contact the State Bar in your state, which appears to be Michigan. http://www.agcmi.com/
If your case in in Brunswick, there is good reason that lawyers turn it down. In the entire history of Brunswick all the way back to colonial days, apparently there has never been a jury verdict in favor of a plaintiff in a medical malpractice case. One local lawyer who incurred the wrath of the local medical community was blacklisted so that no local physicians would even treat his children. Moreover, at least 80% of all medical malpractice cases that go to trial statewide in Georgia are won...
Under Georgia law the claim for property damage is separate from the claim for bodily injury so that the property damage can be settled promptly. Check to make sure that you signed a property damage only release rather than a general release that could include the bodily injury claim too.
There is no automatic legal presumption against you, but as a practical matter I think you will lose this one in traffic court. I hope you have reported the incident to your insurance carrier, which will be obligated to provide coverage and a defense for the claims against you which are likely coming.
If there was a workers compensation case at the time that was not completed closed out with a stipulated settlement, then you should talk with an experienced workers compensation lawyer in Savannah. See http://savannahbar.org/directory. For heaven's sake, don't go with those who run sleazy ads on TV. Savannah has some of the worst in that category.
Every state is different and I have not examined the New Jersey Open Public Records Act. http://nj.gov/opra/ Where I practice in Georgia, we routinely send Open Records requests to police departments for their files, photos, videos, etc. Unless there is an open criminal case, and otherwise if the prosecutor consents, we are at least theoretically able to get these files. The challenges arise when there are notes stored apart from the main file and clerks are not motivated to search.
