How do I negotiate a settlement for a civil summons for past credit card debt?

I have received a civil summons for past credit card debt. The summons was received 2 weeks after the court date. I have contacted the court who advised the summons was not turned in due to this and recommended I contact the attorney listed on the summons in an attempt to work out a settlement. I contacted them and they advised me to submit a settlement offer they can present to their client. I am seeking advice and counsel as to the best path forward and settlement recomendations.
