Let G be a graph with its vertices and edges. On defining bijective function ρ:V(G) →{0,1,...,p}. For each edge assign the label with 1 if ρ*(ab)= | ρ(a)2−ρ(b)2/ρ(a)−ρ(b) | is odd or 0 otherwise such that |eρ(1) − eρ(0)| ≤ 1 then the labeling is called as divided square difference cordial labeling graph. We prove in this paper for relatively possible set of spider graphs with atmost one legs greater than one namely J(SP(1m,2n)) ,J(SP(1m,2n,31)), (SP(1m,2n,32)),J(SP(1m,2n,41)),J(SP(1m,2n,51).
