3. Get Half of Your Spouse’s Benefit
If you’ve been married to your spouse (or had an ex-spouse) for at least 10 years, there’s a Social Security benefit you could be overlooking. If you were the lower earning spouse, you might be eligible to receive up to 50 percent of your spouse’s or ex-spouse’s retirement benefit in addition to any benefit you’re entitled to.
There’s a caveat: To receive the spousal benefit, your spouse must have claimed his or her benefit. Also, you can only receive an ex-spouse’s benefit if you haven’t remarried.
