No. There are no upfront fees.
The general answer here is no. Most lawyers will handle personal injury cases on what's called a contingency fee basis, meaning, if there is no financial recovery for the client, the client doesn't owe anything to the lawyer in terms of attorney's fees. Under these types of arrangements, most lawyers will also advance the costs, including the cost of litigation for the case. Again, if something goes south, there is no recovery. The client is not responsible for reimbursing the lawyer for the costs advanced and doesn't owe the lawyer any money. If there is a recovery, then the costs and an agreed-upon attorney fee percentage come out of the recovery.
