Debts and Credit

Can I sue the person I consigned a loan for for their nonpayment of the loan?

My mother used her money to built on to our house, $150,000.00. It was never written down but said between us that if anything happen or sell, we would pay her back, she has only been in this space 3 1/2 years when my husband and I are divorcing. He says he owns her nothing! I do have emails between us saying he would, us pay her her on the sell of our home. Can she put a on him?

Is it true that if a loan institution passes your debt to another loan institution you are no longer obligated to pay back the debt.

Since Ohio is a non-community property state how would this situation be handled: man & wife but they handle their finances separately. If man gets in a horrific at fault car crash but he doesn't carry insurance & there is for example a $1MM judgement against him. Could the courts also seize the wife's assets &/or garnish her wages? Are liabilities such as a judgement treated like property? And this can be separated (and hers protected) due to the Ohio non-community property laws? Thank you

Is sending someone to small claims court the only way to collect money owed to me. This is a personal matter not business. I had sent this person 3 letters regarding this debt, and never heard a response.
