Tax return is for a married couple. Wife has SE income and wants to claim insurance premiums. Most of the year the husband had an employer who offered health insurance but it was too costly so they did not take insurance through the employer. I know that part of the year she cannot use premiums she paid. Question is about first 3 months of the year when he was changing jobs. He left one job and had the option to continue paying health insurance premiums on policy he had with that company (COBRA). Does the period of time he was elibible for this COBRA disqualify her during that time as well, or can she claim the premiums for that 3 month period?

Thank you
