If you are the owner or an owner, under New York law you could be passively liable for the injuries or damages caused by your friend. Make sure you report any accidents to the insurance company covering the vehicle at the time of the accident. If timely reported, you'll be covered and they'll deal with the claim.
Is this a case you're handling yourself? If you are, you shouldn't be. If you have an attorney, he or she should have put the manufacturer on notice and investigated the possibility of successfully pursuing a products claim. Make sure the sink itself has been preserved and is available to determine why it failed. If your attorney is not looking at this aspect of a claim, perhaps you should consider a second opinion.
You are not "charged" in the criminal sense but you are liable in money damages. If you receive a letter or legal process concerning a particular incident, turn it over to your insurance company immediately. If there was an accident, make sure your carrier is aware of it. Not telling them in a timely fashion may result in the insurance company denying coverage in which case you may become personally liable.
Make sure she gets the medical attention she needs and all relevant insurance companies are put on notice. The statute of limitations for her is tolled until she reaches the age of majority. If something accident related develops in that time, you can always proceed with a claim. You do not indicate if the vehicle was private or public.

The fact that you fell and sustained injury does not, by itself, determine whether or not you have a case. The lawyer may be investigating to figure out who, if anyone, may be liable for your fall. Also, since this occurred such a short time ago, your injuries may not have fully developed. You are always free to change lawyers but a month is not a long time for a lawyer to do a proper investigation. Contact him or her and then, if you're not satisfied, consider asking someone else to take a...
In NY, your exclusive remedy for on the job injuries is workers compensation unless you can show your employer intended to cause your injury or provided no comp coverage which is obviously not the case. As indicated by my colleague, you may have a claim outside of worker's comp if you can show someone other than your employer caused your injury.
There is certainly a chance. It depends on the facts of the accident which are not posted here and given that the matter is in litigation, it's probably not wise to post any further information. Your attorney is in the best position to evaluate both the liability and damages situation. Ultimately, the decision is yours to settle a case or not howver you may be selling yourself short. Sit down with your lawyer and discuss your concerns and what he/she realistically hopes toachieve by...
This is a problem. There is a good chance that defense counsel will be armed with this information as part of their trial prep. You don't want your attorney to hear about this for this first time during your wife's cross examination. He will lose all credibility before the jury and it will be difficult if not impossible to rehabilitate your case. Although you may have already jeopardized the case, do not compound the problem by not telling your attorney. Do it now.
