Everything engaged couples need to know about making a prenuptial agreement valid and enforceable in Maryland — in plain English, reviewed by attorney James Sexton, Esq.
Yes — prenuptial agreements are legal and enforceable in Maryland under common-law contract principles shaped by Cannon v. Cannon.
Maryland is not a UPAA state. Prenups are governed by case law, and the controlling decision is Cannon v. Cannon, 384 Md. 537, 865 A.2d 563 (2005). Maryland treats engaged couples as being in a confidential relationship as a matter of law, so a prenup gets closer scrutiny than an ordinary business contract. The central question under Cannon is overreaching — whether that relationship of trust was exploited, either in how the agreement was procured or in an unfairly one-sided result. An agreement entered voluntarily, with full knowledge of its meaning and effect, and supported by honest disclosure is enforced like any other contract.
A Maryland prenup is enforceable when it was signed voluntarily, with full knowledge of its meaning and effect, and without overreaching — and full, frank financial disclosure is what closes the door on most challenges.
An agreement made in contemplation of marriage should be a written document signed by both parties. A written, signed prenup is the baseline for enforcement in Maryland.
Under Cannon, the agreement must be entered voluntarily, freely, and with full knowledge of its meaning and effect. Springing a prenup on a fiancé days before the wedding invites a duress claim.
Because Maryland treats engaged partners as being in a confidential relationship, each must honestly disclose all property covered by the agreement. Cannon holds that where disclosure is full and truthful, there can be no overreaching.
Courts examine both how the agreement was procured and whether its result is unfairly one-sided. Reasonable terms plus a fair process is what defeats an overreaching claim.

|---|---|
| Property division | Equitable distribution |
| Notarization | Recommended (not required by statute) |
| Waiting period | None required — but sign well before the wedding |
| Spousal support | Alimony can be waived if the agreement passes the overreaching test |

Maryland courts set aside prenups for overreaching — an abuse of the couple's confidential relationship shown by hidden assets, a coerced signing, or an unconscionably one-sided result.
Under Cannon v. Cannon, courts examine both the procurement of the agreement and its result. If financial disclosure was incomplete or the signing was pressured, the whole agreement is vulnerable. But where disclosure was full, frank, and truthful, the attacking spouse is limited to ordinary contract defenses — fraud, duress, coercion, mistake, undue influence, or incompetence — which are hard to prove. Disclose everything, sign early, and keep the terms defensible: that's how a Maryland prenup holds.

No — Maryland law does not require notarization for a prenuptial agreement to be valid. It's still strongly recommended as proof of authenticity, and it's available as an add-on.
Yes — the usual attack is overreaching under Cannon v. Cannon: that the confidential relationship was abused in how the agreement was procured or in its result. Full financial disclosure and an unpressured signing are the strongest defenses.
Maryland law presumes engaged couples are in a confidential relationship — a relationship of trust — as a matter of law. That means prenups are reviewed for fairness more closely than ordinary contracts, which is why honest disclosure matters so much.
Yes. Maryland couples can waive, limit, or set alimony in a prenup, as long as the provision survives the Cannon overreaching test — it can't be procured unfairly or leave one spouse destitute while the other keeps substantial wealth.
No, independent counsel isn't legally required — but each side having a lawyer review the agreement is strong evidence there was no overreaching. Trusted Prenup offers an optional attorney-review add-on for exactly this.
