What Neblett said is correct. If the DOFD is from '99, then it's well past 7-1/2 years and needs to come off. Dispute with the CRAs. Tell 'em it's too old to report.
I believe it's optional. You can tell the CRAs to send updates to anyone you've applied with, but they aren't required to unless you ask.
Paid collections are danged tough to do anything about. Hop on over to creditinfocenter, if you're interested, and there's some discussions about ways to fight those. However, odds are not with you. Worth a shot though. Nothing to lose by trying. Feel free to PM me and I'll point in the right direction.
If it was settled for less than the full amount, then you have some leverage with which to negotiate a PFD. The 7-1/2 year clock starts ticking at DOFD. Generally speaking, an account goes 30 days late, 60 days late, 90 days late, 120 days late, and that month it went 120 days late and stayed delinquent is the DOFD. Also some discussion about tax liens over on creditinfocenter.
For the collection that isn't yours, did you recently receive a written notice in the mail from the CA? DV it and dispute with the CRAs. Use the address on the notice, or the address on your CRs if you didn't get anything in the mail.
"You claim that I owe you a debt. In accordance with FDCPA, send me validation of this debt." Send them your name, address, the account number, and no other info (like SSN). If it ain't yours, then they don't have your SSN and you don't wanna help 'em tag you with it. Send it CMRRR. Same your CM receipt, RRR green card when it comes back, USPS receipt (which has the CM # on it), and a photocopy of your signed letter. Also put a reference line at the top of the letter.
