Recently I was in the hospital for about a month and I also lost my job. The hospital, doctors and labs have started sending bills. Is there a legal minimum amount that I can pay without being sent to collections?
Not in any jurisdiction where I practice (unless the creditor AGREES to accept the payment and to make no further efforts at collection as long as you pay the agreed upon amount).
This "I paid a little so they can't sue me" myth is fairly widespread, but I have yet to find a jurisdiction in which it actually works.
