English translation
If a party to a case pending before the court dies before the court gives judgment, the court shall postpone the hearing until an heir of the deceased, an administrator of the deceased's estate, or another person having custody of the estate has entered the case as a party in place of the deceased, whether by his own application or by a summons issued by the court upon the ex parte application of either party. Such an application must be filed within one year from the day on which that party died. If no application is made by the said persons, or no application is made by either party within the period fixed, the court shall order the case to be struck off the cause list.

Firm annotation
Section 42 addresses what happens when a party dies while the case is still pending, before judgment. The court must postpone the hearing to allow a proper successor, an heir, an estate administrator, or a custodian of the estate, to be substituted as the new party, either on their own application or by summons on the ex parte application of the other side. The provision sets a firm one-year time limit running from the date of death, and paragraph two requires the court to strike the case off the cause list if no substitution application is made in time. It works together with section 43, on voluntary applications to substitute, and section 44, on the summons procedure, and is often applied through special-court procedure statutes such as those for juvenile and family cases. It applies to cases still under trial, not to duties that have already passed to heirs at the enforcement stage.
Why this matters in practice
This one-year deadline is a trap for the unwary: if a party to your case dies and no heir or administrator steps in within one year, the court can strike the whole case, wiping out the progress made. If you are on the other side, you can apply for a summons to bring in the successor and keep the case alive. Sorting out who the heirs or administrator are often means dealing with the estate first, so this is where litigation and inheritance work overlap; our inheritance guide explains the estate side. Act well before the year runs out and get a lawyer to file the substitution properly.

Supreme Court Judgment No. 3902/2568 (2025)
Where a party dies and no heir can be found to substitute within one year of the death, the case must be struck off the cause list under section 42 paragraph two.
The applicant died on 12 December 2023, and the trial court notified counsel to find a person to substitute for the deceased. No heir could be traced to enter as a party within one year of the death. The Supreme Court held that the case had to be struck off the cause list under section 42 paragraph two, applied through section 182/1 paragraph two of the Juvenile and Family Court and Procedure Act, and struck the Supreme Court case accordingly.

Supreme Court Judgment No. 2659/2566 (2023)
When a defendant in a combined criminal and civil case dies, the criminal case is struck, but for the civil part the trial court must arrange for the person designated by law to be substituted for the deceased under section 42.
The defendant died, so the right to bring the criminal case lapsed under section 39(1) of the Criminal Procedure Code and the criminal part was struck off. For the civil part, the Supreme Court directed the trial court to arrange for the person designated by law to be substituted for the deceased defendant under section 42 of the Civil Procedure Code.

Supreme Court Judgment No. 2232/2567 (2024)
Where a defendant dies after judgment while the civil matter continues, the attorney's authority does not end at once, and if the civil part is not pursued within the one-year period referable to section 42, the judgment creditor may still enforce against the deceased's heirs.
The Supreme Court held that on the defendant's death the attorney's authority to conduct the civil part did not immediately cease under the agency rules of the Civil and Commercial Code. When the attorney did not act in the civil part within one year under section 42, the plaintiff could still enforce, because the right of enforcement is a property right, not a personal one, and liability under the judgment passed to the defendant's heirs under sections 1599 and 1600 of the Civil and Commercial Code.
