Good morning Gwen,
Thanks for the additional information. While your husband died before he was eligible to take social security, presuming that he worked at least 10 years in his lifetime, then he qualified for social security as early as age 62.
The fact that he died while married to you, and presuming that you had been married for at least 9 month, then that makes you eligible for a survivor benefit beginning as early as age 60, and a full survivor benefit after age 66.
Now it is not possible for me to know what level of benefit he would have qualified for---however if he earned more money on average than you did during your life, then his social security retirement benefit would have likely been higher than the one you are collecting.
You should contact social security and ask them to consider switching you to a survivor benefit and if that will pay you a larger monthly cash benefit, then that is the one you will be able to collect. A survivor benefit is equal to 100% of the benefit that your husband would have been eligible for at age 66.
When you contact social security (it is usually best to go into a local social security office) be sure to take a copy of your marriage certificate, a copy of his death certificate and both of your social security numbers. Social security will be able to tell you whether they will able to give you a larger social security benefit.
