Real Evidence for Child Custody Proceedings

In parental responsibility proceedings, one parent's word against the other is rarely enough. We work to gather crucial evidence that can determine the child 's future.

Lifestyle Assessment
We investigate whether the parent has habits (alcohol or drug use, or exposure to dangerous environments) that put the minor at risk.
Breach of Agreements
We document cases where court-stipulated visitation schedules or visitation times are not respected.
Detection of Abuse or Neglect
Discreet surveillance to confirm that the minor is being well cared for and that their schedules and basic needs are being respected.

Monitoring of Youth Behavior
If you notice sudden changes in your teenager's behavior, isolation, or suspicious company, our intervention can be preventative:
Identifying Friendships
Find out who your children are associating with outside of home and school.
Substance Use
Verification of behaviors related to the consumption of illicit substances.
Bullying and Online Dangers
Support in identifying risky situations that may be hidden by the child or young person.
