Record of interest

What is the difference of "record of interest in property" versus a quick claim. My mother has already quit claimed us her property and we have already closed on the loan. She now wants to have something recorded that states record of interest. If there were creditors they would recoup her interest by putting a lien on the house and we would have to sell. Wouldn't that impact our credit since the title and mortgage is in our name?

Can she file this document without our approval?
