Many people hesitate to consult a lawyer because they are afraid of the cost.

Even if you have a low income, you should not be deterred from consulting a lawyer. You can obtain a voucher for legal advice („Beratungshilfe“) at the district court („Amtsgericht“) with little trouble, and then the government will pay your lawyer. All you have to pay is a fee of 10 €.

This is the form that you have to take to the Amtsgericht. If you need any explanations, I can easily give them to you by telephone.
When you come to me, I shall also inform you exhaustively of the eventual costs and risks of going to court.
