to LOL,
he cannot do that because if you are married and applying a housing allowance from HMC, HMC will ask a letter from the company that neither the husband or the wife is receiving housing allowance. how can they do that if they are working in the same company, at the same time HMC will do a background check. think man. for married with a grade of 107 and below, you will receive 3k as housing allowance while for 108 and above you will get 5k. you can try to apply the housing accomodation instead of the allowance since you are both working at HMC. you just have to inform the housing section that you want to give up your allowance and avail the housing accomodation.
