Thank you everyone.
I will try to change to unsecure.
I'm not really sure how that's done.
The trustee said to fill out the form "proof of claim" and state it is an amendment. He said I can even do it online. (www.nyeb.uscourts.gov)
Filling the "proof of claim" form, checking amend yes box and checking secured no box is all it take to make it unsecure?
Is it ok to just say it is not secure
