Finding a Person or Business

How to find a person or business you are suing.

Finding a Person or Business


You need to find the person or business you are suing in order to serve them.  You also need to find the person or business if you win your court case and want to collect money.

The court will not find the person or business you are suing for you. Read on to find out different ways to find a person or business.

How can I find a person?

Directory Assistance: You can call 411 to see if there is a public listing. You can use an online directory or search sites such as Google. Enter the Defendant’s name, address, or telephone number to see what information is available.

Reverse Telephone Directory: Reverse telephone directories are often available at public libraries and websites. In a reverse directory, you can look up a telephone number to get the name of the account holder and address if the number is listed.

U.S. Postal Service: If the person you are looking for has moved, consider finding them through the U.S. Postal Service. To do this, send a letter to their last known address and write the words: “Return Service Requested, Do Not Forward.” If the person filed a change of address with the post office, you may get the letter back with their new address.

If the person you are suing has a P.O. Box, you can get a form from the post office called Request for Change or Box Holder Information Needed for Service of Legal Process. Complete the form and include your file number. File the completed form with the post office.

Private Investigator: You can hire a private investigator to find the person you are suing.  This can cost a lot of money.
