The answer turns on a distinction that is both important and frequently misunderstood: the dissolution of the marriage itself is final once the decree is passed and the appeal period has lapsed. Being divorced cannot be undone — except through a successful appeal to the Allahabad High Court within the limitation period. However, the ancillary orders attached to that decree — on maintenance, permanent alimony, and child custody — are modifiable when circumstances genuinely change.

For financial provisions, Section 25(2) of the Hindu Marriage Act expressly empowers the court to vary, modify, or rescind a permanent alimony order on proof of a change in the circumstances of either party. The kinds of change courts recognise include a significant increase or decrease in the paying spouse's income, the remarriage of the recipient spouse (which generally terminates periodic alimony automatically), a serious deterioration or improvement in the recipient's health, or a change in the recipient's earning capacity. An application for modification is filed before the same Kanpur Family Court that passed the original order, with supporting evidence of the changed circumstances — income documents, marriage certificate, medical records, as applicable. The court does not modify orders casually; a genuine, material change must be demonstrated, not a marginal fluctuation.

Custody and visitation orders are treated with even greater flexibility, because the court's concern is the child's ongoing welfare — a concern that does not cease when a decree is passed. If the circumstances affecting a child's welfare change materially — a parent's relocation, a change in the child's school or health needs, the development of the child's own preferences as they grow older, or a parent's changed capacity to provide care — an application to modify the custody or access arrangement is available at any time. The threshold is not "some change" but a change that genuinely affects what arrangement best serves the child. The family law advocates and experienced retired judges at the Kanpur panel of Aapka Legal Advice can assess whether the change in your circumstances meets the threshold for a successful modification application and file it before the Family Court with the right supporting material.

So while no one can undivorce you, the law does not lock you permanently into maintenance or custody terms that life has subsequently made unfair or unworkable.
