Can a family filing jointly hold an HSA and FSA?

Hello, 

 

My family has been Married Filing Jointly for several years. Both spouses have held an HSA account along with a High-Deductible plans. For 2025, my Spouse accidentally opened an FSA. I don't believe we can cancel it per her administrator. My questions are

-What needs to happen to my current HSA? (stop contributing, etc).

-If I stop contributing immediately, can I still use the principle balance of my HSA to pay for health care expenses? Or don't touch it. 

-Is my family forced to start using ONLY the FSA for 2025?

 

Many thanks!!
