Key points
This case in 30 seconds
- Situation
- A couple married in the Mainland and now live in Hong Kong. They were getting ready to divorce when they found their marriage certificate was lost.
- Approach
- We helped them find out how to replace the Mainland certificate and prepared the Hong Kong divorce documents in parallel.
- Result
- Once they had the certificate back, it was filed with the divorce documents already prepared, so the replacement did not slow things down.
Three points for handling this well
- If your marriage certificate is lost, you can apply for a replacement from the Mainland marriage registration authority.
- The replacement and the Hong Kong divorce documents can be prepared at the same time, so you do not have to wait for one before starting the other.
- If both of you are already Hong Kong, Macao or Taiwan residents, check with the registration authority first about where to apply.
Background
A couple married in the Mainland and now live and work in Hong Kong.
They were ready to apply to the court for a divorce when they found their marriage certificate was lost.
They were not sure whether Hong Kong could trace a marriage registered in the Mainland.
- They did not know where to apply for a replacement of a lost certificate
- They worried that Mainland procedures differ from Hong Kong’s and would take a long time
- They were unsure how a replacement could be used in a Hong Kong divorce application
They had searched online, but different websites said different things, and they did not know whether to replace the certificate first or apply to the court straight away.
They wanted to file for divorce as soon as possible, but did not want one certificate to hold the divorce back.
When a marriage certificate is lost, the first thing to work out is how to replace it through the Mainland marriage registration authority and use it in Hong Kong.
Why confirm the replacement first and prepare the divorce documents in parallel?
In this case we chose to replace the Mainland certificate first, because for a marriage registered in the Mainland, the Mainland marriage certificate must be submitted for a divorce in Hong Kong.
Can a lost Mainland marriage certificate be replaced in Hong Kong?
Hong Kong only holds records of marriages registered in Hong Kong. A Mainland marriage certificate must be replaced through the Mainland marriage registration authority.
Where do I apply for a replacement?
To replace a Mainland marriage certificate, apply to the Mainland marriage registration authority.
Since 10 May 2025 applications can be made anywhere in the Mainland. If both of you are already Hong Kong, Macao or Taiwan residents, apply to the authority where you registered, or where you work or live. Check with the authority first.
What is different about replacing a certificate registered in Hong Kong and one registered in the Mainland?
| Marriage registered in Hong Kong | Marriage registered in the Mainland | |
|---|---|---|
| Lost certificate | Applying for a certified copy of the marriage certificate | Apply to the Mainland marriage registration authority for a replacement |
| Where to apply | Any Marriage Registry | Mainland marriage registration authority |
| What it covers | Hong Kong registration records only | Applications accepted anywhere in the Mainland since 10 May 2025 |
| Afterwards | The certified copy can be used as it is | File it together with the other documents once you have the certificate back |
Follow the Mainland rules. Once you have the certificate back, we help you prepare the documents needed for a Hong Kong divorce.

Once you know how to replace the certificate and use it, what remains is how each stage works in practice.
How we helped
From the first consultation to filing the divorce application, the same dedicated consultant follows your case. Our help comes in three stages.
-
Stage 1: applying to replace the Mainland certificate
From the first consultation
At the first consultation, the dedicated consultant learns how the certificate was lost and confirms that a replacement must be applied for from the Mainland marriage registration authority.
We help gather the information needed, and explain how the replacement connects to the Hong Kong divorce application.
Checking the replacement details early is the key to this step.
-
Stage 2: preparing the Hong Kong divorce documents in parallel
While waiting for the replacement
While the replacement is pending, we help prepare the other documents for the Hong Kong divorce application, including organising the information and explaining the procedure.
Once the documents are ready, they can all be filed together when the certificate comes back.
Preparing in parallel is the key to shortening the overall time.
-
Stage 3: collecting the certificate and filing the application
After you get the certificate back
Once the certificate is back, we remind you to check the details on it to make sure they are correct.
It is filed together with the divorce documents already prepared, picking up the work done earlier.
Completing the replacement and the Hong Kong documents at the same time was the key step in this case.
Throughout, the client could phone the dedicated consultant at any time, in Cantonese, Mandarin or English.
For every document, we first explain its contents and what needs following up.
We are a divorce consultancy. We help you organise information, prepare documents and understand the procedure. If your case needs legal advice or a representative in court, we will tell you honestly and help you make other arrangements.
With the three stages joined up, this was the outcome.
Outcome
We first found out how to replace the Mainland certificate, then prepared the Hong Kong divorce documents alongside it, so the two sides fitted together and one certificate did not cause delay.
The direction for the replacement was confirmed at the first consultation, so there was no need to go back and forth between two procedures while preparing the documents.
For the clients, the biggest difference was this: once the certificate came back, it could be filed together with the documents already prepared.
Throughout, the dedicated consultant followed up the documents from the information already gathered, and reminded them of the time limits for the replacement and the filing.
Without doing both at once, waiting for the certificate to come back before starting the other documents often takes longer.
They are now ready to file for divorce, and the case continues on the information already gathered. This was what they cared about most from the start.
How does the procedure change if your situation is different?
The approach in this case reflects a certificate registered in the Mainland and then lost. If your situation is different, the approach will change too.
Married in Hong Kong: If you married in Hong Kong and have lost your certificate, you can apply for a certified copy of the marriage certificate. The situation is similar to the case described earlier.
Unable to deal with it together in Hong Kong: If the two of you cannot deal with the divorce application together in Hong Kong, one of you can apply in Hong Kong without the other’s consent.
Both Hong Kong, Macao or Taiwan residents: If both of you are already Hong Kong, Macao or Taiwan residents, apply to the authority where you registered, or where you work or live. Check with the authority first.
Three things you can do first in a similar situation
- A lost marriage certificate can still be replaced through the Mainland marriage registration authority.
- The replacement and the Hong Kong divorce documents can be prepared at the same time.
- If your situation is different, the procedure may need adjusting, so find out first.
