Is it legal to hire a private eye to spy on someone?

It depends on the situation, but in general, the law in most countries is very concerned with people’s privacy, and private investigators are required to meet certain standards to obtain and maintain licenses.  There are a few exceptions to this, for example in many places it’s legal to conduct surveillance on public spaces.  Also, it’s legal for certain professions to investigate people, such as child protection services or insurance claims inspectors.
