H1b transfer while divorcing wife on H4

[mak83]

I am on H1b and I am in process of divorcing my wife (having a linked h4) with whom I have been estranged for over a year. I am also changing my employer in the US. But, I do not wish for my employer to apply for her new H4 application. Do I need to inform the employer's lawyer or can I withhold the information that I am married? Will this cause a problem in the H1b transfer? What is the best option for such a situation?

Thanks
