You should apply if you are age 65.
Do you plan to delay your benefits when you are 65?
That is the question I need to ask because I think I want to.
Since you want to delay your Medicare benefits then you need to contact Social Security about 3 months before you turn 65.
Btw, for the Rest of the Information I Require. What if my ex-husband is eligible for his own pension?
He can then switch to his own retirement benefit.
May I ask a question about applying for Medicare? What if I forget to register for Medicare?
All you need to do is read the general and special enrollment period on page 12 of the Medicare booklet and also your Medicare coverage could be delayed and cost more.
Are you aware of the benefits payable to family members? What is the maximum amount that a family is entitled to receive?
The limit varies but it is generally between 150 to 180 percent of the basic benefit rate. If the sum of benefits payable to family members is greater than this limit the benefits will be reduced proportionately.
To know whether to apply for Medicare, if I have health insurance through an employer, should I apply  for Medicare?
Yes, you still should check to see whether you need to sign up for Medicare because some health insurance plans change at age 65.
Will other family members or minor children qualify for benefits under my record?
Actually, the value of their benefits added to your own will help you decide if taking your benefits sooner is your best choice.
What if something like an accident occurred?
