Hi.. your concern is how to get a labor card? if you are a husbands visa then your husbands PRO's company (to my knowledge) will arranged it for you. and for the certificate yes you should have an authenticated certificate like your TOR etc, someone from your relative could do it for you. it's easy but not too fast. better starts now.

some company doesn't need it but some did require. There is a ramdom checking for all the companies today. so bettter had one tha caught. I'm not sure for this but my mate mentioned it that to be safe in working for the husbands visa..try to get a working permit in MOI. Much better to inquire and to ba safe for you and for the companies, just get the non-objection letter from you husband and a working permit in the immigration and the authenticated certificates zeal by our embassy and QA
