For more than three decades, Andy Kay has been investigating infidelity cases throughout Los Angeles and globally. One thing he has learned is that successful investigations never begin with assumptions. They begin with facts. He approaches every case objectively, allowing the evidence to tell the story rather than rely on speculation or emotion.
Technology and investigation evolution matter. From smartphones to apps to social media DMs and Signal chats, cheaters are savvy in the rapidly changing social media landscape of the world today. Â What we have found is that while advances in technology have most definitely made it easier for cheaters to cheat, those same technological advances have also made them easier to catch. But we still figure out how to catch them.
Why Many People Wait Too Long
Infidelity can be one of the most traumatic life experiences. It’s hard to know what to do when you begin to suspect your partner of being unfaithful.  Many people do nothing, hoping they are wrong, only to end up broadsided by the truth that eventually comes to light.  Others try to do their own detective work and inevitably fail because experienced cheaters know exactly how to hide the evidence.
Many clients tell us they spent weeks, or even years, questioning themselves before contacting an investigator. They get worried they may be overreacting, damaging their relationship, or accusing someone without proof. Those concerns are understandable.
The purpose of a professional investigation is not to confirm suspicions at all costs. It is to replace uncertainty with objective facts so you can make informed decisions based on evidence rather than fear or speculation.
When You Suspect Something Isn’t Right
Most people don’t contact a private investigator because of a single event.
It’s usually a series of small changes that begin to create doubt.
Perhaps your spouse suddenly works late more often than usual. Maybe they’re unusually protective of their phone, less communicative, or frequently unavailable without a clear explanation. Financial transactions no longer make sense, weekend plans change unexpectedly, or their daily routine has become noticeably different.
Sometimes there is an innocent explanation.
Sometimes there isn’t.
The difficulty is that once trust begins to erode, it becomes increasingly difficult to separate facts from assumptions. Confronting someone without reliable information can permanently change the situation, often making it more difficult to discover the truth.
An experienced private investigator doesn’t begin with conclusions. We begin with facts.
Our role is to objectively document what is happening so you can make informed decisions based on evidence rather than suspicion. Whether the investigation confirms your concerns or provides reassurance that nothing inappropriate is occurring, our goal is always the same: to replace uncertainty with truth.
Common Signs Your Spouse May Be Having an Affair
Every relationship is different, and no single behavior proves infidelity. Many of the changes people associate with an affair can also result from work pressures, family responsibilities, health concerns, or other personal challenges.
However, when several behavioral changes occur together over time, they may warrant a closer look.
Some of the most common signs include:
Sudden Changes in Daily Routine
A spouse who consistently begins arriving home much later than usual, makes frequent unexplained trips, or develops new routines that cannot be reasonably explained may be creating opportunities to spend time with someone else. While schedule changes alone prove nothing, repeated inconsistencies deserve attention.
Increased Secrecy Around Phones and Devices
One of the most common changes investigators hear about involves technology. New passwords, hidden notifications, taking phone calls privately, quickly closing screens, or refusing to leave a phone unattended can all represent changes in behavior. These actions are not proof of infidelity, but they often contribute to growing concern.
Unexplained Financial Activity
Unexpected cash withdrawals, unfamiliar credit card charges, hotel expenses, restaurant receipts, or gifts that cannot be explained may indicate activity outside the normal pattern of the relationship. Financial changes frequently provide valuable investigative leads.
Emotional Distance
Sometimes the first noticeable change is not physical absence but emotional withdrawal. Conversations become shorter. Affection changes. Interest in spending time together declines. While emotional distance can have many causes, it is one factor investigators often hear clients describe before contacting our office.
Increased Attention to Appearance
A renewed interest in fitness, clothing, grooming, or personal appearance is not unusual by itself. However, when these changes occur suddenly and alongside other unexplained behavioral shifts, they may contribute to a larger pattern.
Frequent Business Trips or Last-Minute Schedule Changes
Legitimate work responsibilities certainly exist. But repeated cancellations, unexplained overnight trips, or vague explanations about where someone has been are situations that often lead clients to seek professional answers.
Trust Your Instincts—But Verify the Facts
Many of our clients tell us they felt something was different long before they could explain why. Human intuition can recognize changes in patterns before we consciously identify them.
At the same time, instincts alone should never be treated as evidence.
Professional investigations exist to replace uncertainty with documented facts. Whether those facts confirm your concerns or provide reassurance that your suspicions were unfounded, knowing the truth allows you to move forward with clarity rather than continuing to live with unanswered questions.
We get you answers
while you get back to your life.
Dealing with infidelity causes disruption issues in your personal and your business life which can feel overwhelming. Trying to find the answers and the proof of infidelity on your own is too time consuming, too emotionally charged, and often impossible for the person being deceived.

The Owner and Founder of Kay and Associates Investigations has been licensed and catching cheaters since 1992. Andy Kay is the most prominent infidelity investigator in Los Angeles, California.
Unfortunately, doing a good job often means bad news for my clients. We understand this, and handle each case with the utmost sensitivity and professionalism.
And quite often, long term relationships end upon the finalization of our investigations. However, it is common that our clients need our help through the ordeal, in helping them with child custody, financial asset security, and a number of other services to help them get their lives back in a calm and secure order. We are there from the beginning and work with our clients to help them every step of the way.
We stand out from our competition, not just in how we truly care, but also for the extensive services we offer that most other private investigators and agencies simply do not.
Andy KayLocal Knowledge Makes a Difference
Whether your investigation takes place in Beverly Hills, Santa Monica, Hollywood, West Hollywood, Pasadena, Malibu, Burbank, Glendale, Century City, Brentwood, Sherman Oaks, Studio City, Encino, Woodland Hills, Calabasas, Downtown Los Angeles, Long Beach, Manhattan Beach, Torrance, the San Fernando Valley, or anywhere throughout Los Angeles County, Kay & Associates Investigations has the local knowledge and investigative experience to handle your case with discretion, professionalism, and care.
Successful surveillance is about more than simply following someone. It requires understanding traffic patterns, neighborhoods, business districts, hotels, shopping centers, restaurants, entertainment venues, and the daily rhythms of the communities where people live and work. Every area presents unique challenges, and familiarity with the environment helps investigators adapt quickly while remaining discreet.
For more than three decades, our investigators have conducted surveillance throughout Southern California. We understand the complexities of navigating Los Angeles County, from congested freeways and busy commercial districts to quiet residential neighborhoods and coastal communities. This local experience allows us to develop investigative strategies that are efficient, professional, and tailored to the circumstances of each case.
No two investigations are alike. Whether your spouse lives, works, or frequently travels within Los Angeles County or beyond, we carefully plan each investigation based on the information available, using lawful investigative techniques to document the facts while maintaining the highest level of confidentiality.
Wherever your investigation leads, our commitment remains the same: to provide objective, legally obtained evidence that helps you make informed decisions with confidence.
1st Step to Infidelity Investigations
Information Gathering
First, we speak to our client in-depth about their suspicions, concerns, and goals for the infidelity investigation. Some people simply have a gut feeling that something is going on behind their back, while other clients call us with some proof they have already gathered that their partner is being unfaithful. This is foundation of what we will use to create a plan for investigation and discovery for the case.
2nd Step to Infidelity Investigations
Scheduling
Depending on the timeline needs and goals for the investigation, we will schedule surveillances and/or begin online investigations immediately. The surveillance may need to span multiple days and even require long distance travel, of which we can accommodate. Sometimes, lawyers are involved and we have the needed experience to work with them and know what they expect for court presentations.
3rd Step to Infidelity Investigations
Support & Delivery
We update the client throughout the process and change tactics as needed. There is no set way to do any investigation and it must be flexible and change according to what evidence is being found. Some clients request oral reports while others may need detailed written reports for their case; we can provide either, and in a timely and professional manner.
