Yes, I hired a lawyer for consultation.
Since I was very poor at the time, I could get the cost for it reimbursed from the state, after laying bare my finances in front of a judge.
As for the seriousness, the legal firm moving against me had opened a case before a court in Munich (500km from where I lived) and I had to plead my case in writing to the court.
Next step after a lot of legalese back and forth would have been a summons before the court in person, which didn’t happen. The letters just stopped.
In the end, I paid 60€ for fees and postage. They had wanted me to pay 2000€ to settle and my lawyer told me if it goes before a judge, worst probable outcome would have been 600€ in court and lawyer fees.
