How can a PI help your case?
A private investigator (PI) can play a valuable role in a child custody case by uncovering and documenting evidence that may support your claims or concerns. Here’s how they can help:
1. Documenting Parental Behavior
Substance abuse: Surveillance may reveal drug or alcohol abuse, which could impact custody decisions.
Neglect or abuse: A PI can observe and report neglectful or abusive behavior toward the child.
Violation of court orders: If the other parent is breaking custody agreements (e.g., unauthorized visits, not following visitation schedules), a PI can document this.

2. Lifestyle and Living Conditions
Investigate whether the child’s living environment is safe, clean, and stable.
Document who else is frequently in the home (e.g., potentially dangerous partners, individuals with criminal records).
3. Background Checks
Perform background checks on the other parent, their new partner, or others regularly around your child.
Discover criminal history, outstanding warrants, or other concerning behavior.

4. Witness Location and Interviews
Locate and interview witnesses who can provide testimony or affidavits about the other parent’s conduct or the child’s well-being.
5. Custody Modification Support
If you are seeking to change an existing custody order, the PI’s findings can provide compelling evidence to support your case.

6. Digital and Online Behavior
Investigate social media or online activity that reflects negatively on the other parent’s judgment or parenting.
Important Notes:
Legality: PIs must operate within legal limits—no trespassing, illegal wiretapping, or privacy violations.
Admissibility: Make sure the investigator is experienced with family court so the evidence they gather is admissible in court.
Cost: Hiring a PI can be expensive. Ask for an estimate and clear scope of work before proceeding.
Our team is constantly learning and implementing new techniques to stay ahead of the game.
