Miscellaneous insurance is a generic term used for all types of General Insurance other than the main ones like Fire, Burglary, Marine and Motor Insurance. To have an insurance that comes in handy during times of unemployment one needs to have a Job Loss insurance. This type of insurance covers one's monthly expenses (limited to a maximum amount) for a specified period of months. This payment will happen on a monthly basis till you get a new job or the specified period of months which ever is earlier. At present there are no stand-alone Job Loss insurance products in India, although, a few companies bundle a similar product along with their loan products to mitigate their risk on EMI payments receivable from the borrower.
Ideally, it it good to have a strong health insurance for the entire family to cover any expenses on medical grounds during job loss. And of course take cover for your house against other threats as well. Home loan insurances are only available upon demise of the insured person and not for job loss or such incidences.
