Services of DEFACTO Private Detective Agency
The private detectives at DEFACTO conduct discreet investigations for private individuals in a wide range of situations. Our DEFACTO Private Detective Agency offers tailored solutions for the following areas of operation:
Infidelity and Relationship Investigations
A concrete suspicion of infidelity, cheating, or a hidden double life can place a heavy emotional burden on those affected. Uncertainty, loss of trust, and ongoing doubts can strongly affect daily life and damage the relationship over time.
DEFACTO’s experienced investigators conduct discreet and professional relationship investigations and surveillance. We observe and document relevant activities, contacts, and behavioral patterns carefully and without being noticed.
The goal is to obtain clear and reliable information that helps you make informed decisions—regardless of whether the suspicion is confirmed or disproven. Our discreet approach gives clients clarity about the situation and helps restore emotional stability.
Child Custody and Visitation Matters
In family law disputes, especially in cases involving custody, visitation rights, or child welfare, objective and well-documented facts are often essential. When trust is broken or serious allegations are raised, reliable information can support fair legal decisions.
DEFACTO private investigators provide professional evidence gathering in family law cases. We conduct discreet and lawful investigations and carefully observe, document, and structure all relevant situations and behaviors.
Our goal is to deliver clear and reliable facts for both out-of-court agreements and court proceedings. We help clients gain transparency, security, and the ability to focus decisions on the best interests of the child and their legal position.
Maintenance Fraud and Asset Investigations
f there is suspicion that income is concealed, assets are not fully disclosed, or financial obligations are avoided in separation, divorce, or maintenance cases, this can have serious legal and financial consequences. Clarifying the true financial situation is often essential.
DEFACTO conducts covert investigations, surveillance, and detailed asset and background checks. We also examine private financial arrangements between individuals, such as unpaid private loans, alleged insolvency, hidden asset transfers, or informal agreements.
The goal is to provide reliable and verifiable information that can be used in family or civil law disputes. This helps assess a person’s true financial capacity and verify inconsistent statements about solvency.
Stalking, Harassment, and Protective Measures
In cases of stalking, harassment, or repeated unwanted contact, complete and accurate documentation is crucial for effective legal protection. Victims often face high psychological stress, while evidence is difficult to secure in daily life.
DEFACTO helps document all relevant incidents in a structured way and secure court-admissible evidence. This includes contact attempts, observations in public spaces, and the collection of all safety-relevant information.
Our investigators work discreetly and professionally at all times. The subject remains unaware of any investigation. Our goal is to improve your personal safety and provide a strong basis for legal action such as restraining orders.
Missing Person Searches and People Tracing
DEFACTO Private Investigation Agency provides professional address tracing and targeted people searches when individuals are missing, avoiding creditors, or have not been in contact for a long time. Reconnecting private or business relationships is also a common purpose.
Our experienced investigators use proven research and surveillance methods to determine a person’s current location, living situation, and possible contact options. We carefully evaluate both public and non-public information sources.
The aim is to deliver accurate and usable results that allow successful contact or legal steps. Whether it involves missing persons, debtors, or lost contacts, DEFACTO works discreetly, efficiently, and with great care.
