I realize you have a question about social security. My goal is to help you better understand your options.
Do you have low income benefit or regular social security disability?
If you have regular social security, your children's benefits will not be impacted by your ex wife's new marriage.
Your children get the benefit no matter what - it's their entitlement
Also, if you die and she has remarried, they will still get a benefit from you until age 18
However, your ex wife would no longer be eligible for a widow's benefit - but, your children remain eligible
You're welcome. Please take a moment to rate my response "excellent' so that I may receive credit for assisting you today
