Ajai Agarwal & Ors vs Har Govind Prasad Singhal & Ors

The Supreme Court held that under Section 16(10) of the Uttar Pradesh Urban Buildings (Regulation of Letting, Rent and Eviction) Act, 1972, any enhancement of rent must be supported by a written agreement, and oral agreements for such enhancement are not valid. The Court found that the landlord's claim for increased rent was not substantiated by any written documentation, thus ruling in favor of the tenant's heirs. The appeal was allowed, and the earlier judgments of the lower courts were set aside, reinforcing the necessity of written agreements for rent enhancements.
