Springleaf financial Foreclosure sheriff locking doors in 2 wks letter just sent to other party not me yesterday Evansville Indianna

Equity one sold mortgage to Springleaf since then I was divorced and left house. Ex husband lived there for a year and failed to pay property taxes even when court ordered. He moved out I moved in, I had been paying reg mortgage payment and paying on taxes. Springleaf went and payed the taxes and raised the mortgage and never notified me. They sent letters to ex at his new address even after being told time and time again to sent corresponding to me at the house address. I find out about this 3 months after it was put into effect. I was still paying reg payment.last week I sold my car and sent $1500 for 2 months (mon aug4) I habe had to take personal leave from work before I have a breakdown. My don and his 3 children (2 are autistic) are staying at the house. Today I received a message his father told him he got a letter yesterday that they are foreclosing and he and the children have two weeks to get out before the sheriff locks the doors. I am scared, out of the country with family and have no where to turn or help him. And no notice was sent to me.
