Service of Legal Documents

We receive a number of requests to locate individuals, not only in Perth WA but nationally also. Often the

reason is locate a tenant who may have skipped town with rent still owing and possibly damage to the property. We can usually track these people down but often it comes down to the amount of information our clients have on the people they are trying to locate.

We also track people down to serve legal documents and for people who may be avoiding their child support obligations.

Myths About PI’s

Below we have listed the most common questions we receive as Private Investigators:

  • How much will it cost to hire a Private Investigator?

It is difficult to give an exact cost for an investigation as there are many different types of investigations and circumstances. Most companies will charge an hourly rate, depending on their expertise and the scope of the investigation.

The hourly rate could range anywhere from $80 p/hr to $300 p/hr with the relevant mileage and travel time. This will be agreed upon before the commencement of the investigation and will be in the Service Agreement between yourself and Mercury Investigative Services.

  • Can Private Investigators legally listen into private telephone calls/texts?

 Absolutely not! We as Private Investigators are bound by the Surveillance Devices Act 1998, Security and Related Activities (Control) Act 1996 & the Privacy Act 1988. These Acts clearly stipulate that no conversations can be recorded without the parties consent. So if a company claims they can do this for you then we would suggest to walk away and carry on your search for a more professional, law abiding firm.

  • Can we can access bank accounts?

Private Investigators cannot obtain any such thing, including bank accounts, phone records, medical or criminal records without a person’s consent.

  • Do we have similar authority to Police Officers?

No, Private Investigators have as much authority as the average person in the street- none, although you wouldn’t think this from the way some Investigators act. This means we can’t trespass on private property or access confidential records etc. We are however, licensed and able to conduct investigations into people and have the resources and know-how that the average person may not.

  •  Following someone is easy? 

We have numerous clients who call us after they have attempted to conduct the investigation themselves. Unfortunately it is illegal and not recommended however some people do try to cut costs where possible! Following a Subject takes years of training to ensure discretion is assured and to remain in contact with the Target at all times. It is anything but simple and can be very stressful at times!

  •  Can you locate my partner if they have a restraining order against me? 

Unfortunately we get many queries on this subject and often the caller has not been truthful with us. MIS will not track down a person if we believe the client is acting illegally and/or the person’s safety may be at stake if we provide the information to the caller.
