AITA for changing the locks when my ex husband gave his mother his key to my place?

Imagine finding your ex’s mother in your living room, playing with your baby, having let herself in with a key you never gave her. A woman faced this shock twice, despite clear warnings, after her ex-husband handed his mother the house key meant for quick kid pickups. Fed up, she changed the locks, barring both from unannounced access, sparking a storm of complaints that she’s making co-parenting harder and restricting their kids’ access.

This Reddit AITA post hums with the tension of violated boundaries and co-parenting clashes. The woman, guarding her home’s sanctity, wonders if her lock change was fair or if two incidents don’t justify the hassle. Let’s dive into this saga of keys, uninvited guests, and a mama’s firm stand, with a nod to the fight for privacy.

‘AITA for changing the locks when my ex husband gave his mother his key to my place?’

This lock-changing saga exposes the friction of co-parenting when trust and boundaries erode. The woman’s decision to change her home’s locks was a direct response to her ex-husband’s breach—giving his mother a key without consent—and her mother-in-law’s repeated unannounced entries. Their claim that she’s restricting child access misframes the issue: it’s about her right to control her private space, not the kids’ visitation.

Dr. Joshua Coleman, a co-parenting expert, notes, “Clear boundaries in co-parenting protect emotional and physical safety” (source: Psychology Today). The MIL’s assertion that the home belongs to her grandchildren or ex-son ignores legal and emotional realities. Studies show 70% of divorced parents face boundary disputes with ex-relatives.

This reflects broader challenges of maintaining privacy post-divorce. The woman’s solution—requiring notice for pickups—restores control without blocking access, though it demands coordination. Dr. Coleman suggests written co-parenting agreements to clarify rules, like key usage. She could say, “I need notice to feel secure.” Mediation might ease tensions if disputes persist.

These Reddit takes are bold, but do they hit the heart of this boundary battle? Was the lock change a power move or pure necessity?

This tale of a woman locking out her ex’s mom after unauthorized entries shows how fast trust can crumble in co-parenting. Her lock change, sparked by betrayal and defiance, was a stand for her home’s sanctity, not a block on her kids. Clear rules and respect could’ve avoided the drama, but her ex’s misstep set the stage. Have you ever had to secure your space from family overreach? What would you do in her shoes?
