Spouse visa application with dependent child visa - no whereabouts of biological fath

[joebloggs]

.....in your case you will not need this as you said you were abandoned since your child was 3months old.
Goodluck!!!

i wolud have thought the embassy would want some sort of evidence, because I'm sure many people say they dont know where the father is, thou in some cases they dont, but some will know the father might try and objection if contacted or the child does still have contact with the bio father
