I think I see what you're alluding to, here, but no, that on its own does not constitute domestic violence. Also, the wife, at some point, did give her consent for the husband to change the value of her insurance policy, because the insurer simply would not speak with him unless she had authorised them to do so, so rather than try and insinuate that by changing the value of a life insurance policy, the husband has somehow threatened the wife or made her feel unsafe, the more reasonable response is to contact the insurer and have him removed as an authorised person to whom the insurer can speak.
