Family law disputes are among the most emotionally charged and high-stakes matters that attorneys handle. Whether the issue involves custody of a child, a contested divorce settlement, or an ongoing alimony obligation, the outcomes of these cases shape families for years—sometimes decades—to come. Judges rely on evidence to render fair decisions, and attorneys bear the responsibility of presenting the strongest possible case on behalf of their clients. Yet many family law attorneys overlook one of the most effective evidence-gathering tools at their disposal: professional surveillance conducted by a licensed private investigator.
Surveillance in family law is not about espionage or invasion of privacy. It is a lawful, strategic approach to documenting behavior, verifying claims, and uncovering information that would otherwise remain hidden from the court. When deployed at the right moment and managed by experienced professionals, family law surveillance can be the deciding factor in securing a favorable outcome for a client. For attorneys practicing in South Florida, where complex family dynamics and significant financial assets are common, understanding when and how to recommend surveillance is an essential part of effective client representation.
This guide explores the specific circumstances in which an attorney should consider recommending surveillance to a family law client, the types of evidence surveillance can produce, and the importance of partnering with a reputable firm like Crossroads Investigations to ensure that every piece of evidence is gathered legally, ethically, and in a manner that holds up in court.
A licensed private investigator brings a skill set that attorneys and their clients simply cannot replicate on their own. Professional investigators are trained in discreet observation, mobile and stationary surveillance techniques, evidence documentation, and Florida-specific privacy laws. They know how to follow a subject without being detected, how to capture photographic and video evidence that meets evidentiary standards, and how to compile detailed reports that attorneys can present during hearings or depositions.
In family law, the role of a private investigator extends across a wide range of case types. Investigators can monitor a parent’s behavior during custodial time, document a former spouse’s cohabitation with a new partner, verify or disprove claims of disability or financial hardship, and reveal patterns of conduct that contradict sworn statements. Because surveillance provides objective, real-time documentation of behavior, it often carries significant weight with judges who are tasked with making decisions based on facts rather than allegations.
Attorneys who regularly work with a private investigator in family law matters gain a strategic advantage. Rather than relying solely on testimony—which can be subjective and disputed—they can present concrete, visual evidence that tells a clear story.
One of the most compelling reasons for an attorney to recommend surveillance is when a client raises legitimate concerns about the welfare of a child during the other parent’s custodial time. Family courts prioritize the best interests of the child above all else, and surveillance can provide the court with an unfiltered view of a parent’s behavior when they believe no one is watching.
Surveillance may be warranted in custody cases when the client suspects any of the following:
A skilled private investigator can conduct discreet surveillance that documents these behaviors through timestamped video footage, photographs, and detailed written reports. This type of evidence is far more persuasive in court than a client’s verbal claims alone. Crossroads Investigations specializes in child custody investigations and works closely with attorneys to develop tailored surveillance plans that address the specific concerns of each case.
Alimony obligations are a frequent source of conflict in family law, particularly when the paying spouse suspects that the recipient’s financial circumstances have changed. Under Florida law, cohabitation with a new partner can be grounds for modifying or terminating alimony payments. However, proving cohabitation requires more than a hunch—it demands concrete evidence that the recipient is engaged in a supportive relationship that reduces their financial need.
This is precisely where family law surveillance becomes indispensable. An attorney should recommend surveillance when a client reports indicators such as:
Surveillance can document the comings and goings of a new partner at the former spouse’s residence, capture evidence of shared domestic routines, and establish a pattern of cohabitation over time. Crossroads Investigations conducts thorough cohabitation investigations using a combination of physical surveillance, background checks on the suspected cohabitant, and financial analysis to build a comprehensive picture that supports a motion for alimony modification.
Without surveillance evidence, alimony modification petitions often devolve into a contest of competing claims. With it, attorneys can present the court with objective proof that shifts the burden of explanation to the opposing party.
While Florida is a no-fault divorce state, evidence of infidelity can still play a meaningful role in divorce proceedings. Extramarital affairs can directly affect the equitable distribution of marital assets, particularly when a spouse has been spending marital funds on the affair. An attorney should consider recommending a private investigator when infidelity is suspected and the financial implications may be significant.
Surveillance in infidelity cases can reveal whether a spouse is diverting marital income or assets to support an extramarital relationship, frequenting hotels, restaurants, or other locations with a third party, or engaging in a pattern of deception that undermines their credibility in other aspects of the case.
Beyond financial considerations, documented infidelity can influence custody determinations if the affair has exposed children to inappropriate situations or has destabilized the family environment. An attorney who presents evidence of infidelity gathered through lawful surveillance gives the court a factual basis for considering these factors during asset division and custody decisions.
Crossroads Investigations handles infidelity investigations with the highest level of discretion, understanding that these matters are deeply personal and emotionally sensitive for clients. Their experienced field investigators use proven surveillance techniques to gather admissible evidence while protecting the client’s privacy and legal standing.
Divorce proceedings frequently involve disputes over the true extent of a couple’s marital estate. When one spouse suspects the other of concealing assets, underreporting income, or engaging in financial misconduct, surveillance can provide the evidence needed to uncover the truth.
An attorney should recommend surveillance for financial matters when a client observes warning signs such as a spouse’s lifestyle appearing more affluent than their disclosed income would support, unexplained transfers of funds or property, or the sudden acquisition of expensive items, vehicles, or real estate by the other party or their associates.
A private investigator can monitor a spouse’s spending habits, document evidence of undisclosed assets such as luxury purchases or unreported property, and identify discrepancies between a spouse’s sworn financial affidavit and their actual behavior. This evidence can be instrumental in ensuring an equitable division of assets and in holding a dishonest spouse accountable.
Attorneys recommending surveillance must ensure that their clients understand the legal boundaries within which a private investigator operates. In Florida, a licensed private investigator can lawfully observe and document individuals in public spaces, capture video and photographic evidence of subjects who are in locations where they do not have a reasonable expectation of privacy, conduct interviews with neighbors, coworkers, and other relevant parties, perform public records and database searches, and utilize GPS tracking under specific conditions where the client owns or co-owns the vehicle in question.
However, there are clear legal limitations. A private investigator cannot trespass on private property, record audio without consent (Florida is a two-party consent state), hack into electronic devices or accounts, or engage in harassment or intimidation. Working with a firm like Crossroads Investigations ensures that all surveillance is conducted within the boundaries of the law, which is critical because improperly obtained evidence can be ruled inadmissible and may even expose the client to legal liability.
Crossroads Investigations maintains strict compliance with all applicable Florida statutes and does not include audio in surveillance recordings, does not use GPS trackers unless the client owns the vehicle, and ensures that every piece of evidence is gathered in a manner that will withstand judicial scrutiny.
One of the most important aspects of recommending surveillance is timing. Attorneys should consider the stage of the case, the strength of the client’s suspicions, and the potential return on the investment in investigative services.
Surveillance is often most effective when initiated early in the case, before the opposing party becomes aware that their behavior may be scrutinized. Once litigation is underway and both parties are represented by counsel, subjects tend to become more guarded, making it harder to capture authentic behavior. For this reason, attorneys should discuss the possibility of surveillance during initial client consultations when concerns about custody, cohabitation, infidelity, or hidden assets first arise.
There are also situations where surveillance becomes necessary mid-case, such as when new information surfaces during discovery, when a client reports a sudden change in the other party’s behavior, or when the opposing party’s testimony contradicts known facts. In these scenarios, targeted surveillance can provide the evidence needed to challenge the credibility of the opposing party and strengthen the client’s position.
Selecting the right investigative partner is as important as deciding to pursue surveillance in the first place. Crossroads Investigations has built a reputation as the premier private investigation firm in South Florida, earning recognition from the Daily Business Review as the top investigation firm in the region for seven consecutive years.

Family law attorneys have an obligation to explore every legitimate avenue for strengthening their client’s case.

The key is knowing when to recommend it—and partnering with a firm that has the expertise, professionalism, and legal knowledge to execute it flawlessly.
Whether the concern involves a child’s safety during custodial exchanges, a former spouse’s undisclosed cohabitation, the dissipation of marital assets, or any other issue where documented evidence can make a difference, surveillance offers a path to clarity and accountability. Attorneys who proactively discuss surveillance options with their family law clients demonstrate thoroughness, strategic thinking, and a commitment to achieving the best possible outcome.
