A federal judge in Camden on Tuesday approved settlement of a class-action suit against a New Jersey law firm that allegedly violated the Fair Debt Collections Practices Act by sending out letters that failed to mention the consumer’s right to dispute the debt.

The firm, Mattleman, Weinroth & Miller of Cherry Hill, and its codefendant, Executive Credit Management of Stanhope, agreed to pay $2,500 to the class representative, Monique Wilson, $7,000 to the 225 other class members and $40,000 in fees to class counsel Laura Mann of West Milford, N.J., and Joseph Jones of Fairfield, N.J.
