Yes, on the show "Love Is Blind," couples do actually get legally married if they choose to say "I do" at the altar. The weddings are legally binding, and the marriages are official, meaning couples would need to get a legal divorce if they choose to separate later. This applies to both the US and UK versions of the show. While many couples get engaged, only a few make it all the way to the wedding day, and even fewer remain married over time. The show documents the process from engagement in the pods to the wedding day, including a honeymoon and moving in together before the final decision at the altar.
