In Matter of Ryan Paul L., 112 AD2d 47 [4th Dept 1985] the Court held that the father's "attempts, after the filing of the [adoption] petition" to exercise his visitation rights was not significant. (See id. at 48.) However, there doesn't appear to be any authority, statutory or otherwise, which would preclude the court's examination of a period in excess of six months. On the contrary, in several cases before the Fourth Department, the facts demonstrate that that Court's inquiry typically focused upon a period of time well in excess of six months. In Matter of Ryan Paul L. (supra), the Court examined a full 20- month period prior to the adoption petition. (Id. at 48.)
