Your professional detective agency in Dusseldorf

The PRIMECHECK detective agency in the heart of Düsseldorf operates for you as a business and private detective agency. Our detectives have far-reaching professional expertise and have already gained many years of experience in their field. The private detectives in Duesseldorf are well prepared to identify stalkers, to determine the infidelity of your partner and to eliminate possible alimony issues.

We can both track down the current whereabouts of a dependent ex-partner and also find out his true income situation. In addition, we will of course also find out whether your ex-partner lives in a marriage-like relationship again and is therefore not entitled to your alimony payments. Also in case of theft or plagiarism the investigators of the detective agency PRIMECHECK are at your side.

An appointment can be made at any time by telephone or using our contact form. We would be pleased to welcome you for a personal conversation in our office in the heart of Dusseldorf.
