Does infidelity impact custody rulings in a no-fault divorce?

Instead of citing adultery, cruelty, or abandonment, spouses can simply claim irreconcilable differences or an irretrievable breakdown of the marriage. While infidelity may be emotionally devastating, its direct impact on custody rulings is often limited in states that follow no-fault divorce principles.
