Acquittance

You're done. After 30 years of onerous mortgage payments, you finally own the house...it no longer owns you. What do you get (other than full title, a headache, and the sewer system that reminds you it needs love every summer)? You get an acquittance, which is a paper stating clearly that you no longer own any money for whatever debt you took out to buy that house (or whatever you borrowed money to buy). You are "acquitted" of owing anything more.
