ILE for my son?

[joebloggs]

Ok thank you so much for all your advice!

My son is turning 13 by October !

I got sole responsibility of my son, his dad is not on his birth certificate and he don't see him, we don't know where he is.

I think you mean you have sole custody, that is not the same as 'sole responsibility'

It's possible you could have sole custody but not sole responsibility, or even have sole responsibility but not sole custody
