Enforcement of the liens thus created is not to be denied by equity because the services are to be performed and the assessments charged and collected by an agency other than the covenantee. The defendant cites the case of Riverview Manor Assn. v. Bruckner ( 223 N.Y. 526) in support of the proposition that the covenant here involved cannot be enforced at the suit of one who is not a covenantee and to whom the covenantor was under no obligation at the time of the making of the covenant. But careful examination of the agreed submission of facts in that case will reveal that the covenant there created was a personal one, the grantee agreeing to become a member of the Riverview Association and to pay into the treasury of this association a certain fixed sum on or before January first of each year.
