When an injury lawyer takes a case they do so on the belief that they will have a reasonable chance of success, because they don't work for nothing, they take a huge chunk of the complainants pay out. A lot of this nuisance/vexatious litigation comes when big companies find it cheaper to pay out a nuisance complainant, or not want bad publicity associated with legal action even if they aren't actually in the wrong. Most cases don't even make it to court and are settled with a payout.
If the case went before a jury, or even with a magistrate I would back myself 100%. I have found magistrates not to be sympathetic with people that waste court time. I have also found that magistrates aren't stupid either. Unless there is a case involving archery bows breaking that has set a precedent in your jurisdiction, that clearly states you are in the wrong, stop worrying.
An injury lawyer is not going to sue someone with low assets because even if they won the case they aren't going to get paid. You can't get blood out of a stone.
If you incorporate a business, and then the business gets sued and you are not personally liable. If the assets of the business don't amount to much, the business might close down but you aren't going to lose your house. I don't particularly like this approach but so many weasel businesses that accept your money and fail to deliver the goods to an acceptable standard use this approach. They either close down and re open under another name or declare bankruptcy.
