No, no, no. When you file a lawsuit in Florida in a circuit court you have to state that you're seeking damages in excess of $15,000. There is no top end. Under $15,000 puts you in County court. She is seeking in excess of $15,000, I assure you!
The mother did not file the lawsuit. Suit was filed on behalf of the Estate of the deceased. Any individual with a claim under Florida's Wrongful Death statute has to bring their claim through the Estate.
The Estate is entitled to expenses associated with the death; i.e. funeral bills. A large part of the claim of the estate is the loss of net accumulations; the amount of money the deceased would have had left over at the end of his life, had he lived a normal life expectancy, reduced to present value. I forget if he was in college or had already graduated but one has to assume his potential to earn income over his lifetime was substantial.
Parents normally do not have a claim if the deceased was married. Only the spouse would. In this case the deceased was unmarried so parents are allowed to bring a claim via the estate. That's where the mother fits in. Have not heard mention of the father but his claim is there too if he is alive and was part of the deceased's life. If he was providing any financial support to a parent, that is part of the claim. When there is no spouse, each parent may recover for mental pain & suffering. And THAT is where the big money comes in.
As many have pointed out, no money can bring the deceased back. However, the only method we have of compensating people for such losses is monetary. That's just the way it is.
