On your demise intestate your 50 per cent share in apartment , money in bank accounts would devolve on your mother , your wife , minor daughter 

1. In the case of intestate ( without executing a WILL ) death of a Hindu male person, his self acquired property would devolve equally to his mother ( if alive ), wife and children.

2. In case of your joint ownership of an apartment with your wife, it depends on the narration in the sale deed. Suppose, there's  joint tenancy mentioned in the sale deed, then if one of the joint owners dies, the other joint owner gets full ownership of the property. In case of Tenancy in common, if one of the joint owners dies, his entitled share in the property devolves equally to his legal heirs.

3. In case of ancestral property, your entitled share devolves to your daughter, in case of your intestate death.
