Which court do I file a harta sepencarian claim in?

Usually the Syariah High Court of the state where you live or where the marriage or divorce was registered. Each court's jurisdiction is set by the state's Islamic administration law, and the division of, or claims to, harta sepencarian usually fall under the Syariah High Court. Some states allocate cases by the value of the assets, so ask the counter staff which court is right for your case. Bring your marriage certificate, divorce certificate, a list of assets and evidence of contribution. If you need legal help, ask the Legal Aid Department about eligibility. Every state's court addresses are in the Syariah Court directory.
