1. Lower Costs to Litigate
The legal costs to litigate the claims will be spread across many plaintiffs, so it is more feasible for them to be able to afford to litigate the case. Many class actions are handled on a contingency fee basis, meaning that the plaintiffs do not pay for legal fees unless they win the case.
2. Opportunity to Litigate
Even if each individual claim is not for that much money, a class action lawsuit allows plaintiffs to pursue a worthy cause. For example, A group of buyers pursue their right to claim against the property developer for Liquidated Ascertained Damages (LAD) or Guaranteed Rental Return (GRR). The more plaintiffs join a class action lawsuit, the less legal costs will be borne by each plaintiff, a class action allows such plaintiffs to seek justice.
3. A Greater Degree of Uniformity
For plaintiffs, class action lawsuits allow similarly-situated plaintiffs to recover in a similar manner. Additionally, defendants benefit from class action lawsuits in that they know that many similar claims have been resolved at the end of a trial or settlement.
