Signing the employment contract on behalf of the worker without consent

I have had a domestic worker ‘nanny‘ under my sponsorship for 7 years.

She decided suddenly to terminate our existing contract which will end after 4 months and ran away with her boyfriend!

Tried to negotiate with her to come back till I search for a replacement but unfortunately, she did not agree.

I usually take her with me to renew her working visa and contract in TADBEER. But last year, after reaching there, my son was sleeping in my car and she stayed with him.

I had to sign the work contract on my behalf and her behalf in front of the officer who told me it is ok as she was our nanny for 6 years that time. I’m not sure if I finger stamped on her behalf or not.

My question is: can she file a case that I signed on her behalf on the maid contract?

If she did this, what will the consequences be on me?

Thanks!
