A man came to our house and proposed marriage to me with the intent to dump me when I must have thought it's real. I had a son for him in 2007. He took my son away from me since 2008 till now and hasn't allowed me to see him nor given me information on how I can see him till date. I suffered greatly while searching for my baby. He never apologized till date for all he did to me. He never felt remorseful. I want a simple but effective ritual to invoke karma for all the pains he put me through and to see my son speedily and soonest. I think the kind of karma he deserves is to be useless and without nothing not even a penny, to lose all he has acquired through dubious means while he still held my son. Someone should help me with a simple and effective ritual to make this happen.
I am unsure where you are from or your local laws, but it might be best to contact the police if you haven't done so. You can go to the courts and fight for custody.
Also, in a situation like this, I wouldn't necessarily try to seek "karma" on him. I say this due to a child being involved. I would advise finding a spell to help attract your son back into your life and a spell to help win any future custody battles. You might want the man to be useless and with nothing, but your son still needs to be supported by both parents. A curse to make the man useless might also lose you the ability to see your son, because that father might be the only one who has the ability to bring your son back.
You might want something, but you got to look at how everything and everyone involvedmight be effected.
