Over 50s life insurance plans can be the most hassle to setup, because they often require physical examinations and come with higher premiums.  To set up a competitive policy try a reputable provider, like Legal and General.  To help sort through the plans quickly there are a few things that should be taken into account from the start.
When choosing a life insurance plan, only look at plans in which the premium will not increase for any reason, including age or medical history, as long as it is paid on time.  You should only choose a plan that will not place a financial burden on you at some point in the future. 
Also, choose plans that guarantee lump-sum cash payment at the time of death.  Some insurance companies, including Engage Mutual, offer tax-free cash payments.  Look for these in order to save your loved ones money in the future and to guarantee that the full amount you intended them to have will actually be paid. 
A bonus to look for when choosing plans is an increase in the plan benefit.  For example, Legal and General offer their customers a 10% benefit increase once a life insurance plan has been in place for five years and this does not cost the customer anything.  Finally, you should always examine the fine print and enquire as to how easy it will be for the beneficiaries to claim the benefit.
