When You Suspect Your Ex Is Living With Someone

What Cohabitation Investigations in Columbus, OH Actually Look Like

What do Ohio courts look for when cohabitation comes up? Usually more than a dating relationship. Courts have generally looked at whether two people are living together, whether the arrangement has lasted a sustained period, and whether they share expenses the way a married couple would. Your attorney will know how judges in your county apply that test. Our job is to gather the facts that speak to it.

A few representative situations: a Hilliard client notices a partner's car parked overnight at a former spouse's house most nights of the week. A Westerville client hears that the ex has stopped mentioning rent and a new partner is paying the mortgage. A Grove City client sees a second name on the mailbox and on utility notices. Each needs facts documented over weeks, not a single photo.

How We Build a Cohabitation Case

Which of our services go into a cohabitation case? It depends on what you already know. Each case is planned around the questions your attorney needs answered, using the same core tools we use across our family law work.

Service	How It Helps a Cohabitation Case	Typical Columbus Scenario
Cohabitation investigations	Evidence gathering focused on whether the couple lives and functions as one household	A motion to modify or end spousal support is being considered
Undercover surveillance	Discreet, documented observation of overnight stays, routines, and shared vehicles over weeks	Confirming a partner is at the residence most nights, not occasionally
Background checks	Research on the new partner, including address history and public records	Learning whether the partner lists your ex's home as their address
Alimony investigations	Documenting changes in circumstances that bear on spousal support	Support was set years ago and your ex's situation has changed
Attorney services	Organized reports and evidence your family law attorney can use	Your attorney is preparing a filing and needs documentation

Also dealing with a custody question or a suspected affair? Those cases use many of the same methods, and we handle infidelity and child custody investigations too.

Doing It Yourself or Hiring an Investigator?

Should you gather the evidence yourself, or bring in a professional? Many people start by checking social media or driving past the house, and that can help you decide whether there's something to look into. But a court usually needs consistent, documented evidence, and a former spouse who spots you watching may change their routine.

Factor	Doing It Yourself	Licensed Investigator
Independence	You're a party to the case, so your observations may be questioned	A neutral third party documents what happened
Discretion	Your ex or their partner may recognize you or your car	Unfamiliar investigators and vehicles
Surveillance and documentation	Hard to keep up for weeks while working and parenting	Dated, timed logs, photos, and video as part of daily work
Best fit	Early checks to decide whether to pursue the issue	Evidence for a motion to modify or end spousal support

Not sure whether you have enough to act on? Talk it through with our Columbus team before you decide. The consultation is free, and sometimes the honest answer is that you don't need us yet.

Frequently Asked Questions

Will my ex know they are being watched?

Discretion is the point of hiring an outside investigator. Our work is designed to document what's happening without alerting your former spouse or their partner. How and when findings are shared is a decision for you and your attorney.

Is dating someone the same as cohabitation in Ohio?

Generally, no. Ohio courts have tended to look for a marriage-like arrangement, which usually means living together over a sustained period and sharing expenses. Your attorney can explain how that applies to your decree.

Do you work with my divorce attorney?

Yes. Attorney support is a core part of our practice, and we regularly gather evidence for legal teams. Bringing your counsel in early helps everyone agree on how the work is directed and used.

Do you take cases outside Columbus?

Yes. We serve Columbus and the wider Central Ohio area. Tell us where your former spouse lives during your consultation and we'll confirm how we can help.

What information should I bring to the first conversation?

Bring your support order or decree, your written timeline, the addresses and vehicles involved, and anything you've already saved. If it feels incomplete, that's fine. Sorting out what matters is part of our job.
