mortgage life insurance

i was chatting with my cousin earlier and she mentioned that she recently bought a mortgage life insurance. it was the first time i heard of such so i had to ask her to tell me about it. she bought a condominium unit which is set to be completed in 2009. she is still paying for the said property and will pay for it for the next 15 years. the mortgage life insurance is to pay off her home mortgage if she was to die unexpectedly. i was at first shocked but later on realized she did the right thing. she says that just in case anything happens to her she would at least be assured no one gets burdened by her home mortgage. i never realized such insurances are already being offered. weird but it does make sense.
