AITA for “forcing” my father to pay child support?

Family financial disputes can be incredibly complicated, especially when they involve long-held resentments and legal obligations. I (28F) have always felt that my father abandoned me when he failed to pay the child support I was owed after my mother, a strong, independent woman, refused his demands to quit her job and become a stay-at-home wife.
Despite having a good life and receiving support from my maternal grandparents, my father’s failure left a lasting impact. Now, as I prepare to get married to the love of my life, my paternal grandparents intervened and gifted me the calculated sum of child support—with interest and education costs included—from my father’s trust fund, which has understandably angered him.
‘ AITA for “forcing” my father to pay child support?’
Dr. Laura Markham, a clinical psychologist specializing in family dynamics, explains, “Financial support, especially child support, is a legal and emotional commitment meant to ensure a child’s well-being. When a parent neglects this responsibility, it can have long-lasting effects on the child’s life. Your decision to hold your father accountable, even indirectly, is a reflection of deep-seated feelings of abandonment and the desire to secure your family’s future.”
Dr. John Gottman, a relationship expert, adds, “Family financial disputes often highlight unresolved issues of respect and duty. While it’s understandable that your father is upset about the financial implications for his current family, it’s also important to recognize that you have a right to seek justice for past neglect.
Open, mediated dialogue might be ideal, but sometimes firm decisions are necessary for long-term emotional healing.” Both experts agree that your actions, though harsh in your father’s eyes, are rooted in a desire to correct past injustices and secure a better future for your mother.
Here’s the feedback from the Reddit community:
Several redditors expressed support for your decision. One user commented, “If your father never paid what he owed, you’re not in the wrong for using the money to support your mother’s future. You deserve what was rightfully due to you.”
Another commenter stated, “Child support is about accountability. Even if it’s coming out of a trust fund now, it’s still your father’s responsibility. Holding him to that standard is perfectly reasonable.”
