Margaret Qualley's representatives denied infidelity on July 10, 2026, in her separation from producer Jack Antonoff after three years of marriage, calling cheating rumors "categorically untrue." The dispute matters legally because, in New Jersey, adultery rarely changes the financial outcome of a divorce — the state's no-fault framework under N.J.S.A. 2A:34-2 makes marital misconduct largely irrelevant to property division and alimony.

The rumors ignited after Qualley skipped Taylor Swift's July 3 wedding and removed her own wedding photos from Instagram, while Antonoff was reportedly still wearing his wedding ring. Her team responded that "there was no infidelity or anything outside of respect and partnership," according to TMZ. Because the couple has ties to New York and Antonoff's New Jersey roots run deep, this split offers a useful lens on how three different states — New Jersey, New York, and California — treat allegations of cheating in divorce.
Why this matters legally
Infidelity almost never changes the financial outcome of a divorce in no-fault states, and that reality drives why celebrity denials focus more on reputation than legal exposure. New Jersey, like New York and California, allows couples to divorce without proving wrongdoing. Under N.J.S.A. 2A:34-2, a spouse may cite "irreconcilable differences" that have lasted at least six months, sidestepping any need to allege adultery, desertion, or extreme cruelty.
The public denial from Qualley's team is best understood as reputation management, not legal defense. In court, adultery is one of several fault grounds a spouse may plead, but it rarely alters how a judge divides assets or awards support. New Jersey courts follow equitable distribution, meaning marital property is divided fairly — not necessarily equally — based on statutory factors that generally exclude who caused the breakup. For most divorcing couples, proving an affair costs money and delivers no financial return.
How New Jersey law handles this
New Jersey law makes marital misconduct nearly irrelevant to property division and alimony in the vast majority of cases. The state offers both no-fault and fault grounds, but the financial machinery of divorce operates the same way regardless of which path a spouse chooses.
Property division follows equitable distribution under N.J.S.A. 2A:34-23.1, which lists 16 factors a judge weighs — including the duration of the marriage, each spouse's income and earning capacity, and contributions to the marital estate. Adultery is not among those factors. New Jersey courts have repeatedly held that marital fault is not a basis for dividing property, so a cheating spouse does not automatically forfeit assets.
Alimony works similarly. Under N.J.S.A. 2A:34-23, courts consider 14 statutory factors when setting support, such as the standard of living during the marriage and each party's financial needs. The 2014 alimony reform eliminated permanent alimony in favor of "open durational" awards for marriages of 20 years or longer, and generally caps support duration at the length of the marriage for shorter unions. A three-year marriage like Qualley and Antonoff's would produce, at most, limited-duration alimony — likely far shorter than three years.
There is one narrow exception worth noting. New Jersey recognizes the concept of "economic fault," where a spouse who dissipated marital assets — for example, spending marital money on an affair partner — may owe reimbursement. But this turns on the financial dissipation, not the affair itself. A spouse who cheated but spent no marital money faces no financial penalty for the infidelity alone.
For short marriages without children, New Jersey's irreconcilable-differences path often resolves quickly. The six-month separation-of-grounds requirement is satisfied simply by asserting the differences have persisted that long, and uncontested cases can conclude in a matter of months.
Practical takeaways
Here is what New Jersey residents should take from this celebrity split:
-
Do not assume proving an affair will help your case. In New Jersey, adultery generally has no effect on how a judge divides property under N.J.S.A. 2A:34-23.1 or awards alimony under N.J.S.A. 2A:34-23. Chasing proof often wastes legal fees.
-
Consider the no-fault route to save time and money. Filing under irreconcilable differences avoids a contested fault trial and typically produces a faster, less expensive resolution. Map your options with a personalized divorce roadmap.
-
Watch for economic fault, not moral fault. If your spouse spent marital funds on an affair, document those expenditures. Dissipation of assets — not the affair itself — is what New Jersey courts may address through reimbursement.
-
Understand that marriage length shapes alimony. A short marriage rarely produces long-term support. For a three-year marriage, any alimony would be limited-duration and modest under New Jersey's 2014 reform.
-
Protect your privacy early. Scrubbing social media, as Qualley reportedly did, is a reputation choice — but it is not a substitute for legal planning. Consult a professional before making financial or custody decisions.
