Dear client,

In India, there isn't a specific law that mandates changing flat numbers due to superstitions like the number 13 being considered unlucky. However, some housing societies or builders may accommodate such requests if they're reasonable and don't conflict with any legal requirements or cause significant inconvenience. Changing a flat number typically involves formal procedures, including updating records with municipal authorities and altering legal documents. It might be possible to request a change from the housing society or builder, but there's no guarantee they'll accommodate such a request. It's essential to check with the specific housing association, builder, or relevant authorities regarding their policies on altering flat numbers. Ultimately, superstitions around numbers like 13 vary widely among individuals and cultures. While some people may seek to avoid it, others may not see it as an issue. It might be worth considering if altering the flat number aligns with your personal beliefs and if it's feasible within the guidelines set by the housing society or builder.
