When a Singapore company needs to initiate legal proceedings in a foreign jurisdiction, the foreign court and law firm will typically require the complaint and related authorization documents to be notarized and apostilled before they can be formally accepted. This guide explains the notarization and apostille process for corporate litigation documents, what you need to prepare, and how the complaint, letter of engagement, and company registration documents are typically processed together.
A corporate complaint is a legal document issued by the company itself — it is not a government-issued certificate. It therefore cannot proceed directly to apostille and must first be notarized by a lawyer before the apostille can be applied, enabling it to be formally accepted by a foreign court.

If the destination country is a member of the Hague Apostille Convention, combining all documents in a single notarization booklet and apostilling them together is the most common and convenient approach. However, the following situation requires special attention:
Legal proceedings often have strict deadlines. If you need urgent processing, please contact us in advance with your deadline and we will do our best to prioritize your order. Contact us for a quote.
1. Does the signatory need to appear in person?
No. Simply courier the signed complaint and letter of engagement to our Singapore office by international courier. No in-person attendance is required at any stage.
2. Does the company need to draft the complaint itself?
No. The complaint is typically drafted by the overseas law firm appointed to handle the case. Our role is the notarization and apostille. If you have not yet appointed a lawyer, we recommend doing so and obtaining the draft documents before contacting us to arrange notarization.
3. Must the complaint and letter of engagement be combined in the same notarization booklet?
In most cases combining is recommended — it gives the foreign court or law firm a complete document package in one booklet, which is simpler to process. However, if the destination country requires embassy legalization, some embassies require each document to be independently notarized. Please let us know your destination country in advance and we will advise on the most appropriate approach.
4. Can the certified documents be sent directly to the overseas law firm?
Yes. Once the process is complete, we can courier the documents directly to your appointed overseas law firm or court, or send them back to you for onward delivery. Please provide the preferred delivery address when placing your order.
5. Can I get copies of the notarized document?
No. Singapore notarizations are issued as originals only — no certified copies are produced. If you need multiple sets, each must be ordered and paid for separately. We recommend confirming the number of sets needed before placing your order.
6. The litigation has a filing deadline — can you process this urgently?
We will do our best to accommodate urgent requests. Please contact us as early as possible with your deadline and we will prioritize accordingly. We strongly recommend submitting documents well in advance of any court deadline to avoid last-minute complications.
