DADAE

Hi..im 95% complete my I-130 form...the thing is that for the Bonafide marriage requirements i already have my sons birth cert NSO,Pictures of Proof and i do want to add the AFFIDAVIT OF SUPPORT from my father/friends/relatives..the question is that should i notarize them all? or is it ok to just have the letter of proof that they were and are trustful friends of more than a few years along with their info on DOB address and full name, and that they attended the wedding in which they were invited to...i just want to be safe by adding additional requirements so that i dont have to back track on anything i left out... any help is appreciated..!! thanks.. oh and can i use family members as an affidavit...?
