Must a woman seek her husband's permission to fast a make up fast (qada)?
● If there is ample time to make up for the missed fasts, a woman should seek her husband's permission before fasting.
● However, if the time is running out—such as when only the remaining days of Sha'ban are sufficient to complete the qada—she does not need his permission and must fast, because Allah’s command takes precedence over the husband's consent.

It is stated in Sharh Manhaj al-Tullab (Vol.5/P.261) by Zakariya al-Ansari: "No one may offer a sacrifice on behalf of another without their permission... as opposed to when permission has been granted." And Allah the Almighty knows best.
