Season 19 of Married at First Sight premiered on October 23, 2025, introducing a fresh group of hopeful romantics ready to tie the knot with a stranger. However, before they can say “I do,” participants must adhere to a strict set of nine rules that govern every aspect of the experiment, from legal obligations to filming protocols. These iron-clad regulations, as outlined by PEOPLE, ensure the process remains legally compliant, private, and true to the show’s unique format. Here’s a breakdown of the rules that every couple must follow before and during their journey on Married at First Sight US.
1. Legally Binding Marriages
The cornerstone of the show is that marriages are 100% legally binding in the United States. Couples must obtain a valid marriage license, making their union official beyond the cameras. This isn’t just reality TV drama—it’s a real commitment, recognized by law, that participants enter into the moment they exchange vows.
2. Mandatory Prenuptial Agreements
To protect both parties, all participants are required to sign a prenuptial agreement before the wedding. A show representative confirmed that this legal safeguard ensures financial clarity and security for the strangers entering the marriage, setting clear boundaries for assets and liabilities.
3. Strict Confidentiality with NDAs
Privacy is paramount on Married at First Sight. Every cast member, along with wedding guests, must sign a non-disclosure agreement (NDA). This ensures that details about the weddings and participants’ experiences remain under wraps until the season airs. Season 4 contestant Sonia Granados revealed that everyone involved takes a vow of secrecy, prohibiting social media posts or public disclosures for months.
4. No Public Social Media During Filming
To maintain the secrecy of the experiment, participants are forbidden from maintaining public social media accounts during the filming period. This rule prevents spoilers and keeps the audience in suspense until the episodes are broadcast.
5. Rigorous Psychological and Compatibility Evaluations
Before being matched, contestants undergo thorough psychological evaluations to assess their suitability for the experiment. Pastor Calvin “Cal” Roberson explained that these evaluations include psychological testing, core values assessments, and even considerations of physical traits like body ratios for compatibility. Candidates also complete questionnaires about past relationships, their openness to love, and their personal definitions of love to ensure they’re ready for the challenge.
6. Eligibility Restrictions
Not everyone can join the experiment. The show does not accept applicants with children, though previously married individuals are eligible. These strict eligibility criteria help the experts create matches that align with the show’s goals of fostering lasting relationships.
7. Collaborative Wedding Planning
While the marriages are arranged, couples have a say in their wedding day. They work with wedding planners to choose locations, attire, flowers, and color schemes, ensuring the event reflects their personal tastes. A show spokesperson noted that couples are involved in wedding planning to the extent permitted by production, balancing their preferences with the show’s requirements.
8. Flexible yet Structured Filming Protocols
Filming schedules are coordinated with contestants to accommodate their lives, but they’re still demanding. Some couples are filmed for eight hours on specific days, while others may be filmed daily. Contestants have some control over when filming occurs, allowing flexibility while ensuring the production captures the necessary footage.
9. Support for Therapy and Divorce
The experiment doesn’t end at the altar—it’s an emotional rollercoaster. To support participants, the production team provides financial assistance for therapy during the eight-week filming period. If a couple decides to part ways after filming, the show also covers divorce costs, ensuring participants have the resources they need to navigate the outcome of their journey.
A Structured Path to Love
These nine iron-clad rules form the backbone of Married at First Sight US, guiding participants through every stage of the experiment—from initial evaluations to the final decision at the end of the eight-week journey. By adhering to these legal, financial, privacy, eligibility, filming, and planning requirements, contestants ensure the integrity of the process while embarking on one of the most unconventional paths to love. For the brave singles of Season 19, these rules are non-negotiable, setting the stage for a dramatic and legally binding adventure in marriage.
