A Muslim man divorced before 2019 faces issues with his department demanding a court decree for his divorce, which he cannot provide as his ex-wife's name was never added to his service book. Under Sunni law, a divorce (Talaq) can be validly pronounced orally or in writing without specific formulas, as long as the husband clearly expresses his intent to end the marriage. The core issue is whether the department's request for a court decree is necessary if the ex-wife's name was never officially recorded as a dependent.
