LTCG shared between family members

was your consent oral or in writing. Did it indicate the percentage of ownership in it?

the consent was oral. there is no written agreement...no legal heir certificate also. its by understanding we have shared the sale proceeds from sale of property.

you should really read the query. it helps a lot instead of just spamming.

see, in absence of the legal heir certificate and any formal NOC and your daughter's name not on paper, instead of going for taxation for each heir, I would suggest the sister in law handles taxation in her own return. The net of taxes amount can be equally divided and be shown as a gift to your daughter.
