sorry to read about the refusal..
communications,contact,financial support from the father should NOT be there when you submitted the application ,,you provided some unnecessary information and documents which made the ECO come up with a decision that you dont have sole responsibility with your daughter.
''the father had given an affidavit that he did not support the child from the outset.''
his mother as well gave the same affidavit when we cant get hold of him.
-her biological father lives in the same village and is only a walking distance
-she sees him by accident every now and then
-she dined with him once with me
-''she asked money from him sometimes when she sees him.''
..if your daughter is living with your parents you should have a letter from your lawyer stating that your parents is the guardian of your daughter when you left her...this concerns all the day to day activities of your daughter ,parish,church ,schools extra curricular activities even if your parents act as a guardian it should still be ''you'' who will make the last decision for her ,.. chatlogs and phone calls,remittance slips will prove this and you should provide the documents for this
the only necessary affidavit you can get from the father is an affidavit parental consent that he allows your daughter to settle with you in the UK or wherever...one more thing,we got a member here who just succesfully granted a dependent visa ''rusty'' search his name and message him for more ideas on what to include with your appeal/reconsideration..goodluck and dont lose hope!!
