How Much Does It Cost to Hire a Private Investigator to Prove Infidelity

In relationships, trust is often considered one of the most important factors. But what happens when that trust is broken due to suspicions of infidelity? For individuals grappling with this issue, hiring a private investigator may seem like the best course of action. However, many may wonder about the cost associated with such services. In this article, we will explore the typical fees for hiring a private investigator to prove infidelity and the factors that can influence these costs.

Factors Affecting the Cost of Hiring a Private Investigator

The cost of hiring a private investigator to prove infidelity can vary widely based on several factors. One major factor is the extent of the investigation. The more comprehensive the investigation needs to be, the higher the cost is likely to be. For example, if the client requests surveillance over an extended period of time, or if the investigator needs to travel to different locations to gather evidence, the fees will increase.

Another factor that can affect the cost is the experience and expertise of the private investigator. Seasoned investigators with a proven track record may charge higher fees than those who are newer to the field. Additionally, the location of the investigation can impact the cost, as expenses such as travel, accommodations, and local resources will need to be factored in.

Client expectations also play a significant role in determining the cost of hiring a private investigator. Some clients may desire regular updates, detailed reports, and other forms of communication throughout the investigative process. These additional services can increase the overall cost of the investigation.

Typical Fees

The cost of hiring a private investigator to prove infidelity can range from a few hundred dollars to several thousand dollars. In general, hourly rates for private investigators can vary widely, depending on the factors mentioned earlier. It is not uncommon for rates to start at around $50 per hour and go up to $150 per hour or more, with some investigators charging flat fees for specific services.

In addition to hourly rates, clients should also anticipate additional expenses, such as mileage, accommodations, and any necessary equipment or technology. It is essential to discuss these potential costs upfront and have a clear understanding of how they will be factored into the overall fees for the investigation.


In conclusion, the cost of hiring a private investigator to prove infidelity can be substantial, depending on various factors. Clients should be prepared to discuss their budget and expectations openly with the investigator to ensure that all parties are in agreement. It is also crucial to obtain a detailed contract outlining the scope of the investigation, fees, and any additional expenses that may arise. By understanding the typical fees and factors that influence the cost of hiring a private investigator, individuals can make informed decisions when seeking assistance with proving infidelity.
