II
During the trial, evidence was presented that the defendant received actual notice of the condominium conversion during October, 1979. The plaintiff contends that even if there was a technical defect in the notice given, the defendant's actual knowledge of the conversion could be substituted for the statutorily described notice. We disagree. Compliance with the statutory procedure for notice is a prerequisite to any valid and effective action under the statute. Aurora v. Zoning Board of Appeals, 153 Conn. 623,625, 220 A.2d 277 (1966). "Where a specified mode of giving notice is prescribed by statute, that method is exclusive." 58 Am.Jur.2d, Notice 22; State v. Baltromitis, 5 Conn. Cir. Ct. 72, 77, 242 A.2d 99 (1967). Generally, where notification is required for some definitive purpose, and where valuable interests of the addressee are being destroyed, strict adherence to the prescribed procedure is required. 1 Merrill, Notice 509.
