ANSWER:

What you have done is called slavery and it was totally prohibited to engage in such a transaction and having her work for you all this time without any pay!

You can’t marry her off to anyone as you are not her guardian and surely you can’t get her married without her consent. 

You need to pay her for all these years that she had worked for and set her free to do with that money whatever she pleases.

QUESTION: We took a maid from one of our relatives whose father is missing and mother is mentally retarded. In exchange for her work we agreed to bear the marriage expenses and get her married at the right age. But now she doesn’t get married to anybody and we do not want her to work for us anymore. Can we get her married without her consent as she rejects every single person who comes with proposal?
