Code of Professional Responsibility and Accountability (CPRA)
Section 47. Enforcement of attorney's lien. - In case of non-payment of attorney's fees, a lawyer may resort to the enforcement of the attorney's lien under Canon III, Section 54, by filing a Notice of Enforcement of Attorney's Lien with the court, tribunal, or other government agency of origin where the action or proceeding the lawyer rendered service for is pending, without prejudice to other remedies under the law or the Rules of Court. The Notice shall be accompanied by proof of the services rendered, and served on the client. The court, tribunal, or other government agency, after hearing, shall determine the lawyer's entitlement to the claimed fees. The enforcement of an attorney's lien shall be treated as an independent claim and shall in no instance delay the resolution of the main case. The resolution of the lawyer's claim may be included in the main judgment or in a separate partial judgment. In the case of a partial judgment, the same shall be subject of appeal. An appeal in the main case shall not stay the execution of the lawyer's lien. In the execution of the judgment in the main case, the court shall give due consideration to the pending claim of the lawyer. If the claim for attorney's lien arises after a decision has been rendered by the court, tribunal, or other government agency of origin
on the action or proceeding, the claim for the enforcement of the lien shall be by an independent action.
