In the area of shidduchim, there are numerous rules and regulations that are adhered to in the matchmaking process. For example, it is prohibited for either party in a prospective match to provide false information or to withhold pertinent information, for doing so could result in the actual invalidation of the marriage (Igros Moshe, Even HaEzer 1:79-80). Information regarding serious physical or mental illness, infertility, lack of religious observance, and other such serious issues, may not be withheld. However, one is not required to divulge a deficiency that most people do not consider an impediment, including a minor illness or physical weakness, and there is a dispute between contemporary poskim as to whether it is permitted to slightly “adjust” the age of a boy or girl, when declaring their age. Often, older singles will answer vaguely when asked about their age, and according to some, there is legitimacy to this practice.
