If you didn't exchange informaiton, that's probably the end of it. If you did, and the other person is injured, or has uncompensated property damage, you could be on the hook still. The converse is true also.
This is MUCH too complicated an issue for this forum. You MUST get an experienced family law attorney in your area involved asap! Now that suit has been filed, there are time deadlines that you must adhere to. Move quickly on getting yourself representation....
You need a new lawyer asap. Call Evan Hughes, a very good criminal lawyer in Phila, at 215-731-9500. Tell him I referred you. Under circumstances such as these, the Court is likely to grant you a continuance. Good luck with your case. Slade McLaughlin
You most likely could sue in either the US or Canada (but not the UK, which would likely lack in personam jurisdiction). You should choose whichever country's law is more favorable to you, and contact a lawyer there. If you are looking for specific recommendations, please feel free to contact me directly. Thanks.
Report the accident to your insurance company asap and get a lawyer appointed. Why are you being sued? Your lawyer should move to have you dismissed asap. Presumably, you had no knowledge of your wife's condition (nor did she), so you certainly should not be responsible. There may be caselaw permitting your wife to file for summary judgment if this was an unforeseeable event. You mentioned your property and medical coverage, but what is your LIABILITY coverage? That's what is implicated here....
If you were wanted for questioning about a domestic violence incident, and your car fit the description, that would be probable cause to stop you. If you were found to be driving and drunk at the time, that arrest would not be illegal.
