In the “Ahsan Form” of talaq, the talaq is effective:-

In the Ahsan form a single pronouncement is made during a tuhr (period of purity) followed by abstinence; it remains revocable during the iddat and becomes final "on the expiration of Iddat period". Immediate effect on pronouncement is a feature of talaq-ul-biddat, and successive pronouncements belong to the Hasan form; a written talaq-nama is not what completes Ahsan talaq.

Current law: For covered marriages in Uttarakhand from 27 January 2025, section 29 of the UCC requires dissolution in accordance with the Code, so an Ahsan pronouncement does not by itself dissolve such a marriage.
