Sorry to hear about your refusal.
Without knowing what details you supplied with your application, it is difficult to give any further advice on what more you could supply.
For our recent application for my wife’s son, we had to wait 2 years to apply for his application due to various financial reasons and while he was still in the Philippines he was staying with her parents and family.
The biggest doubt that we had with the application was with sole responsibility. One of the reasons that I think our application was approved is that the father is not named on the birth certificate and has had very little contact and no support to his son.
We supplied 3 letters of support in the application, from my wife as the sponsor, me as co-sponsor and the mother of my wife who has been looking after him while my wife was away.
In these letters we explained the father’s lack of contact and also gave the reason, backed up with evidence, as to why it took that long to apply for the visa. The letters also highlighted that since my wife has been away she has kept in contact and been consulted on all decisions to do with her son. We also supplied receipts showing she supported her son since she was away.
Good luck with your appeal.
