English to Slovak Law/Patents Law: Contract(s)

Although I understand the concept, I don't know how to translate it in Slovak. Here is a definition from Wikipedia:
An indentured servant (also called a bonded laborer) is a labourer under contract to work for an employer for a specific amount of time, usually two to seven years, to pay off a passage to a new country or home. Typically the employers provided little if any monetary remuneration; however, they were responsible for accommodation, food, other essentials, and training.

And here is context from the translated text:
They were trafficked into the country for sexual exploitation, forced marriage, and indentured servitude in domestic service or businesses.
