Weltman Weinberg & Reis seem to sue just prior to the expiration of SOL.
You need to pull all three of your free credit reports and research them
for your date of last activity and date of last payment for that account.
All of the info you need should be there as far as account number
past due balance and possibly date of last activity.
If you have any bank statements from 2001, search them for any
cancelled checks you paid the account with, to find when your
last payment was.
Do not take what they are showing you ( as far as a statement ) as fact
they made many errors in my case..they still won, but made alot of errors..
Sometimes all you need is one good error to tip it in your favor.
"A statement" is not proof of when you paid on the account last.
Make them provide a copy of your cancelled check, sometimes they
can't present it..
If you find you are beyond SOL then amend your response if possible,
to include that as a defense.
They are going to charge your account for any and all court appearances
they attend so make them prove what you owe and why.
If they provide "evidence" that you owe this money..pick every bit
of it apart and compare it with what YOU have..look for errors
and show those errors to the judge.
Argue everything, respectfully..
Attend every court session so they don't get a default judgement.
If they offer to settle prior to court and you can afford to do so
consider it.. but don't agree or acknowledge the debt until you know
for sure where you stand as far as SOL.
Also, research as much as you can online and on these boards I learned
so much from doing this..above all, don't be scared, you won't go to jail...
