A legal reservation of a liability insurance company is the expression of the insurer`s agreement to defend its policyholder on the limited condition that it does not waive a right to later refuse coverage under the conditions of insurance.  A reserve of law allows an insurer to adapt to its broad duty of defence while avoiding the waiver, waiver or forfeiture of rights or the indictment of a judgment against its policyholder and to warn the policyholder to take steps to protect himself from the insurer who reserves.  An insurer that reserves its rights may recover from its own taker certain sums that have been spent on defence costs and settlement costs.  A right that does not yet exist cannot be created by reservation.  A valid legal reserve does not require the approval of the policyholder.
