Capital Gains Avoidance

Hello Ladies,

Need advice on the followins:

1. How best to avoid Capital Gains?
2. I have seen bonds being offered as a solution. Where can I purchase them?
3. How much of the capital gains can be invested in one financial year? Can family members purchase bonds for part of the gains, instead of the homeowner alone?
4. Can anyone recommend a good real-estate lawyer in Chennai that canreview sale deeds, etc?

Thankyou.
