The best visa process to follow to move to Jakarta

Easy - Turn up on a tourist visa, rent a place in Bintaro sector 9 (South Tangerang), there are several nice estates in THIS area, then get yourselves off to the Immigration office in Tangerang, taking all your documents with you, immediately applying for a KITAS with MERP.

Marriage to an Indonesian and proof of work outside Indonesia should make the ride easy and pretty quick. The cost will be about 60 to 70 quid per person. You won't need an agent as it should go through on the nod as long as you have all your documents. If it was a Muslim wedding, that makes life easier in some cases, but any legal wedding will do the job, but maybe with some extra playing around.

The British school is crazy expensive, but you have to see the place to believe how great it is. Travel from Bintaro 9 is very easy.

Get your daughter an Indonesian passport whilst in Brunei from the Indonesian embassy, failing that start the paperwork side of things for her whilst in Brunei and complete in Jakarta when you arrive, (your wife can do the application in Brunei or Indonesia but will be easier whilst overseas as your children I presume are not registered as residents in Indonesia just citizen?)
Get your singapore marriage certificate translated to Bahasa if not already registered the marriage in Indonesia along with your birth certificate (translated and legalised) to register the marriage in Indonesia you'll need all documents issued from Indonesia officials before/ after marriage plus a photo of you together and your passport
