Andrew engaged the services of Atty. Juju under a contingent fee agreement to help him file a complaint for damages against his employer, Wilkon Shipping, Inc. Atty. Juju handled Andrew's case for two (2) years before the Labor Arbiter and the National Labor Relations Commission (NLRC), filing the necessary pleadings and attending several hearings. The complaint, however, was dismissed. To improve his chances, Andrew replaced Atty. Juju with Atty. Jen, who eventually succeeded in getting a favorable decision from the Court of Appeals, which became final. When Andrew's claims were satisfied by Wilkon, Atty. Juju filed a collection suit against him claiming that he (Atty. Juju) is entitled to attorney's fees for the services he rendered for two (2) years. Will the collection suit prosper? Explain.
