No quick answer exists that will address the merits of a particular settlement offer. Rather, any evaluation is a careful cost-benefit analysis that considers the amount of the settlement compared to the damages of the injury. Another part of the analysis is the benefit of receiving compensation immediately, as opposed to waiting for a trial judgment. The possibility that damages from a trial might be lower than the settlement is also an important factor in the decision.
An experienced attorney can provide recommendations and guidance regarding a settlement, but the choice to settle always belongs to the client.
