Married sisters who apply for subsistence allowances do not need to fill in the form. Because after getting married, my sister is no longer the main member of the family, but is counted as a member of her husband's family. Therefore, her income cannot be counted as the income of the family applying for subsistence allowances, and it is not necessary to fill in the information of married sisters when applying for subsistence allowances.
The above is the general situation, and the specific provisions may be different due to different regions and policies. It is recommended to consult relevant departments or institutions to obtain accurate information.
