As far as remember goes they mean the exact same thing. Recordar algo = Acordarse de algo. Acordarse  needs the de recordar doesn't. Recordar also can mean to remind and acordar to agree.
Typically Bankruptcies will stay reported on your Credit Report for 10 years (per Fair Credit Reporting Act (FCRA) ). However, fortunately, most of the Credit Reporting Agencies will remove then after 7 years has passed.
However, there are a few rules regarding the reporting of negative information. For example, a late payment cannot be reported on a credit report unless it is at least 31 days late. After that time, it usually shows up on the credit report within the usual 30 days. Creditors usually do not charge off a debt and turn it over to a collection agency until 180 continuous days of non-payment have passed, so you may have at least six months before a collection or charge off shows up on your credit report.
