Unfortunately even though your father will contribute nothing his income is still considered when applying for financial aid. You will need to look at cheaper schools or schools where you can get more merit.
@singleandreadytopringle, colleges like Northeastern (CSS Profile schools) don’t care what the divorce papers say. They expect both parents to contribute according to what the college thinks is appropriate based on each parent’s income, assets, etc. If the colleges didn’t, then every family with divorced parents would play the game of saying only one parent (the less wealthy parent) would pay.
You need to talk to your father and explain this to him. See if he is willing to contribute. Otherwise you will have to look at schools that give significant merit or schools that only use the FAFSA and only take the custodial parent’s income into account. Unfortunately most every top tier school uses the CSS Profile and will require him to pay.
What @mom2collegekids said. If he did not pay anything before 18, then go after it. No matter what was agreed, he must pay your support before 18. A judge has to sign off in a “no support” agreement.
