Good morning house. Please if some one legally married wife get pregnant outside and give birth, can d legal husband claim the child or if after so many years u discovered ur 12 year old child is not yours, can u claim d child since u are legally married to d woman. Do u need legal permission to claim d child.

Yes
But not legal permission, what you need is traditional permission or kinsmen permission. Even the law can't force someone's child to be yours, but family can.

my brother I can not claim because I was not there.

Why will you want to claim a child that's not yours?

Tough one.. I think you can claim it by legal adoption. However, I think some conditions must be established... Like the father is no more or the baby was abandoned without traces of father.
