A Saturn square would be of use in the situation someone has too little Saturn influence in their life. High Priestess Maxine Dietrich explained about such situations here:

"Saturn always gets the bad rap [obviously], but I have noted in charts  that either have an unaspected saturn, or saturn with no hard aspects,  the lives were anything but happy. One woman I knew had a life in total  chaos. Saturn is known for stability and this woman had NONE. By the  time she was 30, she had been married 5 times, she had 3 kids [not from  any of the husbands], she put all three up for adoption [one was 4 at  the time], and this haunted her every single day of her life. Her  self-esteem was total shit, her health was horrible, she could never  stay very long on a job or live very long at any permanent residence, as  circumstances always came up. She was bi-sexual, but went through men  [no stable relationships of either sex]. She had 29 of scorpio with  sagittarius intercepted in the first. Ruling Pluto at one of the worst  degrees 15 of Leo. 
 
 Saturn at its positive gives endurance and stability."
