Just gone through the process of ROM in JPN Putrajaya and would like to share some info.

I guess in most cases, Chinese would like to have the ROM done in Tien Hau temple. But found out that it's only permitted if either one is Buddhist. Since we are both Christians, JPN is the best option. In order to avoid hassle, we went straight to the one in Putrajaya.

Then comes the funny part. I'm from Selangor and my wife is from KL. She can submit her form in Putrajaya. But for me, I need to submit in Petaling Jaya. Kind of odd considering that JPN Putrajaya is supposed to be the HQ. Here's the loophole. In the building itself, you can update your Selangor MyKad address to KL address. Just cost RM7. Far cheaper than driving all the way back to Petaling Jaya and paying for toll and parking. After updating my address to KL address, we headed back downstairs to the ROM department. Since both candidates are KL 'residents' now, we can proceed as usual. Submitted stuff like IC and passport sized photo. Blue or white background does not matter.

They'll provide a date for you if there's no preferred ones. The list is quite full for the month of September. So, do expect them to give you a date which is more than a month eventhough the 'notice board' thingy is 21 days. They'll inform you that the time is at 8am. But when we check the letter, it shows between 8m-11am. Information from the internet says that you need to submit the witness's photocopy IC (and nominate 2 names). But they didn't ask us for it. Still, be safe and bring it. When this is done, go home and wait for the big day.

On the actual day, we arrived before at 7:30am. There's already a couple before us and another 3 more after us. So, be there early. First come first serve basis. After presenting your letter and IC, they'll print out a form for you to double check. Verify the information. They'll ask you to wait. In less than 10 minutes (depending on crown as well), they'll announce your name and room number. Head inside and wait for the officials to arrive. During this time, feel free to take pictures.

When the official arrived, the bride, groom and witness will sit down. Others are still allowed to take pictures but be abit respectful. Both bride and groom and stand up and do acknowledge some oath thing. Just some simple "yes" and "kami faham" words. The official will read the stuff for you. Now, time to sign the cert. You are now officially a couple. The official leaves the room. You'll have a few minutes to take more pictures (there's even an arch for decoration) and exchange rings.

That's all. Feel free to send a PM if you need more info. I've heard that Tien Hau temple requires some sort of "akuan sumpah" but JPN Putrajaya seems simpler. All done in less than an hour under the same roof.

Nowadays, only certain churches is licensed to conduct the ROM during the wedding mass itself. Mainly old ones like Assumption in PJ. My parish is in a different place and my wedding is not held there. Therefore, we had to do the ROM first, then wedding mass.
As for "why Tien Hau Temple", it opens on weekend. Can save up the annual leave. But at that time, we didn't know it's tied to religion. Thought there's a JPN proxy there who can do for non-muslim.

Nope. Putrajaya didn't need the sumpah thing. Hence, that is why I didn't want to do it in Tien Hou. Because of the hassle of sumpah, I'll still need to bounce a few places if go through Tien Hou. Well, another reason is, at least one side must be Buddhist to register in Tien Hou. Both me and my wife aren't.

I had the exact same issue. Officially, your GF can register in Putrajaya because her IC is KL. You on the other can will need to register in Putrajaya, then bring a form back to Selangor NRD office. in short, it will be a hassle. You can't do everything in one place.
But here's the loophole. In that same Putrajaya building, you can update your IC. Change your address to KL. You don't need to change the physical card. Just update the chip. The whole process including waiting time takes less than 30 minutes. Once both IC is considered KL, head back to the marriage department and register as both KL. You can now skip the whole "Selangor NRD" thing.

2 years ago, we registered in Putrajaya. And yes, BOTH must be from KL. The person who is not from KL must take a form and get it stamped in their state. For example, if I am from Selangor, I'll need to get a special form, go to PJ registration office and get it stamped, then bring it back to Putrajaya. Sounds weird because I thought Putrajaya is like the hub for all govt dealings. So I changed my MyKad address on the spot to KL as a loophole. The MyKad process took only 15 minutes and can be done in the same building.
