When a former spouse receiving alimony begins living with or receiving substantial support from another person, the paying spouse may question whether the existing alimony obligation remains appropriate. However, observing that two people are dating, spending time together, or occasionally staying at the same residence does not necessarily establish grounds for modifying alimony.
Florida courts examine whether a “supportive relationship” exists. Proving that type of relationship may require evidence demonstrating shared residency, financial interdependence, mutual support, or conduct resembling a permanent marital partnership. A professionally conducted cohabitation investigation can help document relevant activities and provide objective evidence for an attorney to evaluate.
Optimum Investigations conducts discreet cohabitation and supportive-relationship investigations throughout Florida. We assist family-law attorneys and private clients by documenting living arrangements, recurring overnight stays, shared activities, vehicle patterns, property use, and other observable facts that may be relevant to an alimony modification proceeding.
What Is a Supportive Relationship Under Florida Law?
Under Section 61.14 of the Florida Statutes, a court may consider whether an alimony recipient has entered into a supportive relationship with someone who is not related to that person by blood or marriage.
A supportive relationship is more than casual dating. The court evaluates the complete circumstances surrounding the relationship. Relevant considerations may include:
- How long the individuals have resided together
- Whether they use the same mailing address
- Whether they present themselves publicly as a married or permanently committed couple
- Whether they have combined income, assets, or financial accounts
- Whether one individual pays the other’s expenses or debts
- Whether they jointly own or maintain real or personal property
- Whether they provide valuable services to one another
- Whether they work together in a business
- Whether they financially support each other’s children or family members
- Whether an agreement concerning financial support or property sharing exists
The law does not require the individuals to be married or to refer to one another as husband and wife. It also does not require proof of an intimate relationship. Instead, the court considers evidence showing the nature, duration, permanence, and financial effect of the relationship.
Does Cohabitation Automatically Terminate Alimony?
No. Cohabitation by itself does not automatically terminate an alimony obligation.
Two individuals can live at the same address without being in a supportive relationship. They may be roommates, relatives, tenants, friends, or individuals who maintain separate financial lives. Likewise, a romantic relationship involving frequent visits may not include the financial interdependence or permanence necessary to establish a supportive relationship.
The court—not the investigator—determines whether the evidence satisfies Florida’s legal requirements. An investigator’s role is to gather and document objective facts that an attorney may use along with financial records, testimony, social media evidence, property records, and other discovery.
For that reason, an effective investigation should look beyond isolated overnight stays and establish a broader, well-documented pattern of conduct.
How Can a Cohabitation Investigation Help?
A cohabitation investigation can help determine whether the circumstances justify further legal and financial investigation. It may also produce documentation that supports or contradicts information provided during litigation.
Depending on the circumstances, an investigation may document:
- Vehicles regularly present overnight at the residence
- Repeated arrivals and departures over an extended period
- Whether an individual appears to maintain a daily routine from the residence
- Transportation to and from work
- Regular access to the property without the alimony recipient present
- Use of keys, garage-door openers, access cards, or gate credentials
- Receipt of household deliveries or mail
- Participation in household maintenance
- Grocery shopping and transportation of household supplies
- Joint travel, dining, shopping, or recreational activities
- Attendance at family functions and social events
- Public conduct indicating a committed relationship
- Shared use of vehicles or other property
- Activities associated with jointly operated businesses
- Statements or representations made publicly or through social media
No single observation ordinarily tells the entire story. The strength of an investigation usually comes from documenting consistent conduct over multiple dates and comparing those observations with public records and other available information.
Surveillance in Cohabitation and Alimony Cases
Surveillance is frequently an important part of a cohabitation investigation because it can establish patterns that may not be apparent from a single visit to the residence.
For example, an investigator may document that the same vehicle arrives every evening and remains until the following morning. More extensive surveillance might show that the individual leaves the residence for work, returns afterward, transports groceries into the home, performs maintenance, uses the property while the recipient is away, or routinely participates in household and family activities.
These observations can be documented through detailed, time-stamped reports, photographs, and video when legally permissible. Conducting surveillance on multiple weekdays and weekends may provide a more accurate representation of the living arrangement than surveillance performed on one isolated date.
Investigations must always be conducted from lawful vantage points and in compliance with applicable privacy and surveillance laws.
Public Records and Online Research
Surveillance may be supplemented by public-record and online research. Depending on the case and the information lawfully available, research may help identify:
- Property ownership
- Vehicles associated with the individuals
- Business affiliations
- Corporate registrations
- Professional licenses
- Court filings
- Address connections
- Public social media content
- Photographs of vacations, celebrations, and family gatherings
- Public references to a shared home or long-term partnership
Social media can be especially helpful when individuals publicly describe themselves as a couple, announce an engagement, document shared travel, discuss a joint business, or post photographs showing an established household relationship.
Online information should be properly documented and preserved. A screenshot without identifying information, dates, context, or source details may have limited value. Professional documentation helps maintain an organized record for the client and attorney.
Financial Evidence May Also Be Necessary
Private investigators can document activities and uncover relevant public information, but many supportive-relationship factors concern finances that cannot be established through surveillance alone.
Bank statements, utility accounts, leases, tax filings, insurance policies, payment applications, credit-card records, and other financial documents may require formal discovery, subpoenas, or authorization. A family-law attorney can determine which records are legally obtainable and how they should be requested.
The most effective approach often combines investigative findings with legal discovery. Surveillance may identify patterns and connections that help an attorney decide which records or testimony to pursue.
How Long Does a Cohabitation Investigation Take?
The appropriate duration depends on the circumstances of the case.
A short investigation may determine whether a suspected partner’s vehicle is regularly present overnight. A more comprehensive investigation may require surveillance over several nonconsecutive weekdays and weekends to establish a reliable pattern.
Factors affecting the investigation include:
- The individuals’ schedules
- Whether they use multiple residences
- Whether vehicles are parked in garages
- Access restrictions in gated communities or condominiums
- Work-related travel
- The length and nature of the suspected relationship
- The amount of evidence already available
- Upcoming filing or hearing deadlines
Beginning the investigation before filing a petition can be important. Florida law addresses whether a supportive relationship exists or existed during a specific period preceding the filing. Clients should consult a qualified Florida family-law attorney before determining when to begin an investigation or file a petition.
What Makes Cohabitation Evidence More Persuasive?
Persuasive evidence is generally lawful, objective, consistent, and supported by detailed documentation. It should establish a pattern rather than rely on assumptions.
A vehicle parked outside a residence for one night may have an innocent explanation. The same vehicle documented at the residence overnight on numerous weekdays and weekends—combined with observations of the driver leaving for work, returning in the evening, accessing the home independently, and performing household tasks—can provide a much clearer picture.
Investigators should report what they actually observe without exaggerating or making unsupported legal conclusions. The final report should allow the attorney and court to distinguish documented facts from assumptions.
When Should You Contact a Private Investigator?
You may want to speak with an investigator if:
- You believe your former spouse is living with a new partner
- A partner appears to spend most nights at the residence while maintaining another address
- Your former spouse and the partner appear to share household or living expenses
- They present themselves publicly as a married or permanently committed couple
- You suspect they jointly operate a business or own property
- You need objective documentation before discussing modification with an attorney
- Your attorney has recommended surveillance or background research
- A hearing or filing deadline is approaching
Clients should avoid confronting the individuals or attempting to conduct surveillance themselves. Confrontation can cause behavior to change and may compromise a future investigation. It can also create safety, privacy, or legal concerns.

Frequently Asked Questions
Can a private investigator prove that my former spouse is cohabitating?
An investigator can document activities consistent with shared residency, including recurring overnight stays, daily routines, independent property access, household activities, and shared travel. The court determines whether the complete evidence establishes a supportive relationship.
Is proof of a romantic or intimate relationship required?
Florida’s statute states that a conjugal relationship is not necessary. The court focuses on the relationship’s permanence, financial effect, mutual support, and other statutory factors.
Is one night of surveillance enough?
Usually not. One observation may show that someone stayed overnight, but it may not establish a consistent living arrangement. Multiple surveillance periods can provide stronger evidence of recurring behavior.
What if the person maintains a separate address?
Maintaining another address does not necessarily mean the individual actually lives there. Surveillance and research may help document where the person regularly sleeps, begins the day, keeps a vehicle, receives deliveries, and conducts daily activities.
Can you enter a gated community to conduct surveillance?
Investigators must follow applicable laws and property restrictions. The investigative plan will depend on lawful access, available public vantage points, the community’s layout, and the specific circumstances.
Can social media posts be used in an investigation?
Publicly available posts may provide relevant information about the relationship, shared travel, household activities, family events, businesses, or property. The material should be properly preserved with identifying details and context.
Will hiring an investigator guarantee that my alimony is reduced?
No. An investigator cannot guarantee a legal outcome. The court evaluates the evidence, statutory requirements, financial circumstances, and arguments presented by the parties.
Should I contact an attorney or an investigator first?
Whenever possible, consult a Florida family-law attorney first. The attorney can evaluate your agreement or judgment and help identify the evidence needed. Optimum Investigations can then coordinate the investigative approach with you and your legal counsel.
