I don't understand a couple of things about your post:
Generally when one "opts out" of a settlement it refers to a class action settlement proposed and the party "opting out" disagrees with the amount and then proceeds on his or her own with their own lawyer independent of the class action. You say that you opted out but you are still part of a class action ?
Next-in a class action there are no attorney fees that the individual members have to pay. The attorney fees come directly from the settlement should there be one and or the verdict should the matter proceed to trial and then only if they win.
Many people are unaware that attorneys in a class action lawsuit typically don’t get paid unless they win the case, either at trial or through a settlement. They are generally paid a percentage of the money that’s recovered on behalf of the Class Members. This money is referred to as “attorneys’ fees.”
Attorneys’ fees must be reviewed and approved by the court. The judge will take a look at how much work the lawyers have put into the case, the total value of the judgment and the amount of money that it is reasonable for Class Members to recover. Although each case is different, a court will generally approve attorneys’ fees that are about 25 to 35 percent of the settlement fund.
