Husband not paying court-ordered interim maintenance of ₹20,000 per month — how do I enforce the order?

The court has already passed an order in your favour and your husband is in clear violation of it. You have strong legal remedies available and you should not hesitate to use them. The immediate step is to file an execution petition before the same Family Court that passed the interim maintenance order. In execution proceedings, the court has the power to attach your husband's salary directly from his employer, attach his movable and immovable property, and if necessary direct the sale of attached property to recover the maintenance arrears. The court can also strike out his defence in the main proceedings if he continues to disobey the court order, which would be a significant setback for him. These are powerful tools and the threat of salary attachment alone is often enough to compel compliance. Regarding your advocate's concern about a High Court revision petition — that is a risk in any litigation but should not deter you from enforcing a lawful court order. You also have the right to independently file a revision petition before the Sessions Court seeking enhancement of the maintenance amount, challenging the reduction from ₹25,000 to ₹20,000. On the question of future increases linked to his salary, the law permits you to file an enhancement petition before the Family Court whenever his income increases or your expenses grow. You should ensure that his current salary slips, Form 16, and income tax returns are already on record. Each time he receives a salary hike you can bring it to the court's notice and seek a proportionate revision upward. There is no fixed formula but courts generally consider the standard of living, the needs of the child, and the paying capacity of the husband while deciding enhancement applications. Do not wait — file the execution petition at or before the December hearing and let the court deal with his non-compliance directly.
