So, basically, in 2007 you purchased a home and secured a mortgage in your name, even though you had no income. Your ex-boyfriend made all of the payments.

In 2008 your then-boyfriend borrowed about $30,000 from his father, and you agreed that he could use your home as security - presumably because he was making all of the payments? Exactly how is this loan secured - a mortgage and note? A lien? This is the loan you purport to be "predatory"? What do you imagine "predatory" to mean in this context?

In 2012, although your ex-boyfriend has continued to pay your house payments. he has not paid off the @$30,000 loan from his father? If not, who is making the payments?

(If you want a court to order your ex-boyfriend to pay child support, petition for child support.)
