As you pray for them start with the OLDEST PROBLEMS AND ACCESSES FIRST. Put any claim they make under the blood of Jesus, forbid them to do any more work against the person, and send them immediately and permanently to where ever Jesus wants them to go. Usually starting with generational spirits first is a good idea. Make sure there aren’t any of them working and then go from there.
Here is a sample prayer you can use to get started:
“Gracious Father over all, I acknowledge before you the sins of my parents and ancestors. I know that they have sinned because all men and women are sinners. And so, I openly confess the sins of my parents and ancestors. I know I cannot do what only they could have done in attaining forgiveness of their sins, but I am sorry for their sins against you and I ask that you cover their sins with the blood of Jesus and not hold their consequences against me or my descendants. I claim the finished work of Jesus Christ, Who bore all my sin upon Himself. In faith I accept that work on the basis of your holy Word. I reclaim any consent given to Satan’s forces by my parents’ sin. Dear Jesus, please set me free from all evil influences coming from my parents and ancestors in the name of Jesus. I know I am a new creation in Christ. Old things have gone and all things have become new. I here and now reject and disown all the sins of my ancestors. As one who has been delivered from the power of darkness and translated into the kingdom of God’s dear Son, I cancel out all demonic working that has been passed on to me from my ancestors. As one who has been crucified and raised with Christ and who sits with him in heavenly places, I reject any and every way in which Satan may claim ownership of me. I declare myself and my descendants to be eternally and completely signed over and committed to the Lord Jesus Christ. I now command every evil spirit and every enemy of the Lord Jesus Christ that is in or around me to flee my presence and never to return. I now ask You, heavenly Father, to fill me with Your Holy Spirit. I submit my body as an instrument of righteousness, a living sacrifice, that I may glorify You in my body. All this I do in the name & authority of the Lord Jesus Christ. Amen.”
Next pray about childhood events and experiences: trauma, rejection, etc. Put them under the blood of Jesus, take back any access demons claim through them and send them to where Jesus would have them go.
Then deal with sins and openings that have come since childhood. Take your time and be thorough. There is no hurry and no rush.
This is an important step so spend time thinking about this. Ask God to give you wisdom and insight as needed..
