JPMorgan Chase Mortgage Complaint

JPMorgan Chase Mortgage department,

Home equity loan or line of credit Settlement process and costs New York

I currently have a Home equity line of credit, which is 30 years, first 10 years are for draw, remainder 20 years is to pay back line of credit. My bank contacted me to ask if i want renew credit line, but said i would have to pay filing of lean, which would come to about $240000.00. I asked the bank since there still is a lean for another 20 years, why would i have to pay. They said thats the way it is. My question is that necessary, or can they continue to use same lean. The home is located in New York State. Thank you- -
