Some accidents can happen on Tucson city sidewalks or government property. Sovereign immunity for the government does not include immunity from these types of negligence lawsuits when the government failed to maintain its property.There are different rules in effect when suing the government. You have far less time to file a lawsuit against the government. While the normal statute of limitations is two years in a personal injury case, you have only 180 days to sue the government. In addition, you need to file a notice of the claim that provides specific facts that demonstrate your legal right to money along with the amount that you will accept in a settlement. You need to support those numbers in your claim. The government has lawyers whose job it is to protect their employer, so you need your own attorney who can take on the government.
