Reader question: Which forms are required for a return to Belgium?

take a plane, live in your house or rent something, and file a declaration at city hall. Notify the embassy that you are living back in Belgium once you have an address here. Depending on your age, see where you should register, retired not of course. Is .Arranging the health insurance fund here.

I think it's a rather odd question. The Embassy needs to know what is needed in your case and if they are 'unclear' about it then check back or ask for someone who knows more about it, as far as I'm concerned even the ambassador himself! After all, that's what an embassy is for. Readers of this blog have made their own experiences. But that is an individual thing, and if you follow some advice, you may fall into a trap.
Success!

Dear Gery,
I'm surprised they can't give you the necessary information at the Belgian embassy. It is, however, a very simple matter: returning to your own country.

There is no problem for you: you simply go back to Belgium as a Belgian and you report this to the embassy where they will adjust your file as "no longer living in Thailand".
Once you have arrived in Belgium, go to the town hall and register again in the population register of your new place of residence (within 8 days). After checking by the community police officer whether you actually live at this new address, your identity card will be adjusted or renewed. You inform all services again: health insurance fund, taxes….. see unsubscribing file for Belgians, but in reverse order.

For your wife it's a different pair of sleeves, there will be more work to be done there, but shouldn't be a real problem.

I assume that she used to have an “F card” (2005). This is valid for 5 years and can then, upon request, be replaced by a Belgian identity card. She will NOT have this because you only lived together in Belgium for 3 years and one of the conditions is : 5 years of uninterrupted residence in Belgium. 6 months, reported absence is allowed as well as some exceptional cases that do not apply to you.
So in short: the F card has expired because you have not lived in Belgium for 5 years.

Even if you are married under Belgian law, she will need a new residence permit (visa) for Belgium because she does not have Belgian nationality. This must be applied for at the Belgian embassy with the following documents and on the basis of "family reunification". This procedure will not be completed in a very short time, as everything must be sent to the Immigration Department and you will first have to make sure everything is in order in Belgium.

Necessary documents:

passport or identity card of the country of origin (possibly with a visa)
if applicable: employer's certificate and/or work card/professional card
passport photos with white background
certificates of civil status (birth, marriage and/or divorce certificate) – possibly translated and provided with legalization or apostille

You will also have to submit certain documents as you will have to guarantee her:

identification
proof of residence
proof of income
proof that you lived together in Thailand ( investigation into marriage of convenience by DVZ )

My personal advice for a simple and legal handling:

first go to Belgium ALONE and initially arrange all administrative matters there: registration, residence... then, if necessary, come back to Thailand to assist your wife in the procedure to be followed and once all of this has been Then return together to Belgium where they can apply for an F card again and restart the entire previous program.

good luck, Lung addie.
