A man is seeking to use a video of his wife participating in a Mundan ceremony as evidence of her second marriage in a maintenance case. While the video itself may not be conclusive proof of a second marriage, it could potentially be relevant. However, legal experts advise that substantial evidence of a valid second marriage is required. Maintenance may still be payable until the date of the second marriage, even if proven. Consulting a local lawyer with the video and all relevant details is strongly recommended for accurate legal advice.
