Given that you have very little earned income (assuming this has been your pattern for many years) and your husband is highly compensated, you might consider collecting your benefits at age 62 then changing to spousal benefits at age 66 when he is age 70. They will be 1/2 of your husband's.
I also strongly recommend that your husband consider filing and suspending at age 66 then begin collecting benefits at age 70. This will allow his benefits to grow by 8% per year and will also give him the flexibility to change his mind and collect benefits in arrears that he would have received had he begun collecting at age 66.
Why would he do this? For example, say he has a normal life expectancy of living until age 90 but is diagnosed with cancer at age 68. Because he now has a shortened life expectancy, he might not break even on waiting to collect. The SSA will let him revert back to age 66 and collect at that rate, paying out back benefits.
By waiting until age 70 and letting his benefits grow, however, he will not only receive a much bigger check each month, you will be guaranteed that same much bigger widow's benefit if he should die before you. There is nowhere I know of that you can earn an 8% guaranteed return. I hope you will consider this strategy.
Your local Social Security Administration office should be able to answer any questions you have to help you arrive at the right decision for you.
Good luck and I hope this helps!
