The law is reluctant to recognize obligations based solely on family relationships. However, the failure to recognize these commonly observed obligations as legal obligations is in large part derived from a concern that intra-family litigation would exacerbate strained relationships and weaken rather than strengthen the sense of mutual obligation underlying family relationships. See, e.g., Kilgrow v. Kilgrow, 268 Ala. 475, 107 So. 2d 885 (1958) (judicial intervention in family affairs more likely to serve as 'spark to a smoldering fire' than to prevent disruption); McGuire v. McGuire, 157 Neb. 226, 59 N.W.2d 336 (1953) (no action for maintenance and support where married couple living together).
