Requires disclosure of third-party litigation funding agreements and establishes certain responsibilities for litigation funders.

This bill requires parties in civil lawsuits to disclose any third-party litigation funding agreements to the court and all parties at the time of filing or when the agreement is made. It establishes that litigation funders must act in the best interest of the funded party (a fiduciary duty), prohibits them from influencing case decisions or taking more than 25% of settlement proceeds (with a combined 50% cap including attorney fees), and bans them from offering legal advice or assigning funding agreements. Funders become jointly liable for costs or sanctions against the funded party, and agreements violating these rules become unenforceable. The bill directly affects civil case participants and third-party funders by increasing transparency and limiting funders' control over litigation outcomes.
