I would need some more information such as how the ladder was positioned, who positioned it, what the surface was like and your medical treatment thus far. As my colleagues below have stated, it depends on the homeowner's insurance policy language and when it occurred.
That is an unfortunate situation. Was your colleague injured? The casino should still have the surveillance so it is important to speak to an attorney immediately. I will provide a complimentary case evaluation if you would like to give me a call or send a private message.
A lot of times attorneys are able to negotiate medical liens down so you will not be responsible for the full amount. However, I can only determine whether this would apply to you by reviewing the specific facts of your case. I am happy to provide a free consultation if you would like to contact me. My email address is email@example.com. Thanks.
You should definitely speak to an attorney. I am happy to provide a complimentary evaluation. I am a strong negotiator, especially with insurance companies. I used to defend them. I am also happy to provide a discount since you are further along in the process than most.
That sounds awful. Best wishes to your father on a speedy recovery. I am more than happy to discuss your case with you, but would like to know some additional information before commenting here. Please send me a private message or call me to discuss.
