I agree with my colleagues. I would also like to add that most personal injury attorneys offer a free consultation. Your friend should immediately consult with a personal injury attorney. Waiting and unnecessary delays could hurt your friend's case.
Attorneys would need more information to provide a general response. Most personal injury attorneys offer a free consultation. You should schedule a consultation with a local personal injury attorney. It sounds like you have a serious case. Don't rely on a general response on this site when a consultation could analyze your entire situation.
It is possible. There are cases that address this issue. You can also Google Florida dog bite landlord liability and see what comes up for your own edification. I would personally not rent to a tenant with these dogs. Talk to your insurance company and attorney to protect yourself prior to doing anything.
I agree with my colleague. I am a little confused about the post. Feel free to re-post with more details. In general, amending a complaint can be accomplished. Did you consider hiring an attorney for help?
If you have not scheduled a consultation with a personal injury attorney, you should immediately do so. You did not post any facts about the accident. There may be issues of liability and potential monetary damages available. Attorney should assist their clients with medical bill issues. I do agree with my colleagues.
It is my opinion that it would not be easy to set aside the judgment. I believe the court would be loathe to change a signed agreement that the judge ultimately signed. Your ex had an opportunity to challenge the signed agreement prior to the court signing the judgment. However, she might allege duress of some sort, and make up a creative and compelling reason for the court to consider, but I think it's a long-shot especially if it sounds like she's making stuff up.
The issues relating...
I agree with my colleagues, and would like to add another point. Since you don't know what side your attorney is on, it would probably be worth it to consult your own attorney. You can ask the attorney if you can pay for a limited scope of representation to review what is going on. There is a lot riding on the line, and the last thing you would want to have to consider is a potential bankruptcy.
Dog owners can be liable for dog bites even if there is no history of dog bites. California Civil Code Section 3342 and 3342.5 are a couple code sections you may want to consider. Some people are shocked to find out they don't have the appropriate insurance coverage. You really need to consult with a defense attorney, especially if your insurance carrier hasn't covered you for dog bites. Check with you carrier.
