Divorce cases are not just emotional battles; they are also legal battlegrounds involving complex financial, custodial, and personal issues. When disputes arise over infidelity, hidden assets, or child custody, a private investigator (PI) can serve as a powerful ally. PIs provide objective, lawful, and sometimes critical evidence that can impact legal decisions and ensure justice for their clients. Let’s explore how private investigators contribute to divorce proceedings in six vital areas.
1. Uncovering Infidelity and Marital Misconduct
While many states in the U.S. allow for “no-fault” divorces, infidelity can still influence divorce outcomes—particularly in areas where “at-fault” divorces exist. In these cases, one spouse must prove that the other engaged in misconduct such as adultery or abandonment.
Private investigators help collect concrete proof of such misconduct through:
- Surveillance: Observing the subject’s activities without direct interaction.
- Photo and video evidence: Capturing moments that suggest infidelity.
- Digital investigations: Scraping public social media accounts or online dating profiles.
- Witness interviews: Speaking with neighbors or coworkers for corroboration.
If a spouse is cohabiting with a new partner, especially in jurisdictions where that could affect alimony, this information becomes legally relevant.
Example: In North Carolina, evidence of adultery can impact the awarding of spousal support under § 50-16.3A of the General Statutes.
2. Asset Tracing and Financial Investigations
Hiding assets is one of the most common tactics in high-conflict divorces. A spouse may attempt to underreport income, transfer funds to a third party, or conceal property.
Private investigators use forensic accounting techniques and access to databases to:
- Examine tax filings and bank records
- Detect sudden withdrawals or large unexplained transfers
- Uncover offshore accounts and shell companies
- Investigate business ownerships and unreported properties
Their findings help attorneys push for equitable distribution of marital assets under state law.
Example: In California, spouses are required to fully disclose all assets and debts. Failure to do so can result in penalties or a more favorable judgment for the innocent party.

3. Child Custody Investigations
When children are involved, the stakes are even higher. Courts must determine what custodial arrangement serves the child’s best interest—a subjective standard often involving detailed scrutiny.
Private investigators assess:
- The safety and cleanliness of a home
- A parent’s behavior, lifestyle, and routine
- Drug or alcohol abuse
- Neglect or endangerment
- The presence of unsafe acquaintances or partners
Their work involves both direct observation and background checks, often resulting in detailed reports with timestamps, photos, and logs that can be used in court.
Example: A parent trying to gain full custody may need to show that the other parent has a pattern of leaving the child unattended or associating with dangerous individuals.
4. Surveillance and Legally Obtained Evidence
The cornerstone of private investigative work is legal surveillance. Surveillance is not just about “catching someone in the act”; it’s about documenting patterns that support claims of misconduct, neglect, or fraud.
Types of surveillance may include:
- Mobile surveillance: Following a subject discreetly.
- Stationary surveillance: Watching a subject from a fixed location.
- Electronic surveillance: Monitoring online behavior or email (with legal constraints).
It’s important that surveillance is conducted legally. Any evidence obtained illegally—such as tapping phones or placing hidden cameras in private spaces—can be inadmissible and may harm the client’s case.
Example: Surveillance capturing a parent regularly dropping off their child at an unsafe home could influence custody outcomes.

5. Investigating New Partners or Childcare Providers
After separation, one parent may start dating or introduce new caregivers. This can be a source of concern for the other parent, especially when the new individual has a questionable background.
Private investigators can:
- Run criminal background checks
- Investigate restraining orders or prior domestic violence
- Verify employment and income
- Examine online behavior and associations
This information can serve as grounds to restrict unsupervised visits, request custody modifications, or challenge cohabitation-based claims for alimony adjustments.
Example: If a parent is dating someone with a history of child abuse or drug offenses, the court may prohibit overnight visits while that individual is present.
6. Expert Testimony and Courtroom Presentation
Private investigators often provide sworn testimony and detailed reports that are submitted as part of a legal case. A professional PI understands how to:
- Present findings clearly and factually
- Maintain a chain of custody for evidence
- Remain objective and professional under cross-examination
In some cases, PIs are subpoenaed to testify, especially when credibility is contested or a judge wants clarification on the evidence.
Example: A PI’s testimony that documents a spouse violating a restraining order could significantly impact both custody and property division outcomes.
Final Thoughts
Hiring a private investigator during a divorce is not about “spying”—it’s about uncovering the truth and ensuring that justice is served. Whether the issue is infidelity, hidden wealth, or concerns about child welfare, PIs help level the legal playing field. Their work often becomes the backbone of a compelling court case.
When considering hiring a PI, make sure they are licensed, ethical, and experienced in family law cases. A good investigator not only uncovers the truth but also ensures that their findings are legally admissible and useful in court.
