The engagement – although traditionally used in social life k did not have any legal regulation in the modern Romanian legislation, prior to the enforcement of the new Civil Code (October 1st 2011), namely: the Civil Code of 1864 and next, the Family Code. Instead, the new Civil Code (Law no. 287/2009, republished on July 15th 2011) regulates engagement in art. 266-270. The authors of this study analyze the aforementioned enactment of engagement, concluding that the express regulation of this private law institution in the new Civil Code is beneficial.
