EUTR1 form

Hi ladies and gents

A quick question, I have a job and a place of residence in galway, I have a completed the EUTR1 form for my wife and included paperwork required including utility bills and marriage certificates etc.

The only part if the form I am not sure of is for the children (2 boys not mine) but are hers with proof of birth certificates.

What should I send for proof of them residing with me and do I have to prove they are dependent on myself or because they are only 9 does the INIS not need too much info about them.

Sorry if this is a dumb question I just want to make sure I have got everything correct before sending form.

Thanks in advance
